A Pew Research survey found that half of all respondents are more concerned than excited about the use of AI in
their daily lives, up from 38% just three years ago. The concerns fall into several categories, including anger over
the lack of choice to use AI. See Brian Kennedy et al., How American View AI and Its Impact on Society, PEW RSCH.

AI experts have a more favorable opinion of AI than the general public, but they still don’t exactly understand
how it works. Pew Research Center found that “[f]ully 56% of AI experts surveyed say AI will have a very or
somewhat positive impact on the United States over the next 20 years. This compares with 17% among the general
public.” Colleen McClain et al., How the U.S. Public and AI Experts View Artificial Intelligence, PEW RSCH. CTR.

witnesses and many top-notch experts who are beginners when it comes to machine learning and
AI. 19
Does this mean that a rule isn’t necessary? Perhaps not. It may be that a specific rule is
needed to address machine learning. It seems short-sighted to propose a rule that excludes
technically savvy experts, sweeps in lay witnesses who may not have the knowledge to discuss
certain reliability issues related to machine learning and algorithms, while also requiring courts to
engage in gatekeeping. The risk of related satellite litigation over very basic tools and instruments
that have been reliably admitted as evidence outside of the scope of a Rule 702 analysis seems
high and could needlessly bog down trial courts.
Finally, the prongs of 702(a)-(d) are not easily applied to AI or machine learning tools. It
would be better to draft a rule that doesn’t require the application of another rule. On this point,
LCJ and AAJ are in rare agreement. 20 Not only are the prongs of 702(a)-(d) hard to apply to
machine outputs, but there is also a risk of creating diametric court decisions and circuit splits.

How to Improve the Proposed Rule

AAJ recommends that the Evidence Committee go back to the drawing board and answer
the basic questions of what needs to be covered by a machine-learning rule first. Almost all
information is machine-generated, including vast amounts of financial data for both business and
personal use. To require all machine-generated evidence, which is routinely brought into court by
both expert and lay witnesses, to undergo a thorough 702 reliability analysis could significantly
delay trials and lead to unnecessary appeals. Alternatively, the Committee could decide that a rule
on machine learning is needed now, but that capturing almost all machine-generated evidence is
unnecessary. While some on the Committee may be concerned with an underinclusive rule, an
overinclusive rule would have a greater impact on the courts. To the extent that the Committee
concludes it will move forward with a rule at the conclusion of the comment period, it would be
easier to strengthen or clarify a less-inclusive rule through amendment than it would be to repeal
a rule that has overreached. 21

A. Narrow the rule to focus on machine learning
At its November 2025 meeting, the Evidence Committee discussed an alternative to the
proposed amendment on the “Output of a Process of Machine-Learning.” 22 This draft limited the
rule by focusing on the specific concerns that have been brought to the attention of the Evidence
Committee and are the impetus for moving a draft rule to public comment. Unlike the version of
the rule published for public comment, this option provided a detailed definition of machine
learning in the first sentence of the Committee Note, complete with descriptions of how these
systems work and relate to artificial intelligence:
Machine learning is an application of artificial intelligence that
is characterized by providing systems the ability to
automatically learn and improve on the basis of data or
experience, without being explicitly programmed. Machine
learning involves artificial intelligence systems that are used to
perform complex tasks in a way that is similar to how humans
solve problems. Machine-learning systems can make predictions
or draw inferences from existing data supplied by humans.
When a machine draws inferences and makes predictions, there
are concerns about the reliability of that process, akin to the
reliability concerns about expert witnesses.

A definition would help ensure that parties and courts understand the scope and application
of the rule, including that it addresses new technology and is not intended to slow down trials over
machine outputs widely accepted by the public today and generally understood to be reliable.
Further, this refinement would assist the court in assessing data where a human provides certain,
often minimal, inputs, while the machine calculates other numbers or information. For example,
truckers are responsible for starting their vehicle’s Electronic Logging Device (ELDs) at the start
of their shift by logging in, but it is the device itself that automatically records driving time, miles
driven, and other key data. 23 ELDs are widely accepted as reliable, but it would be unfair to burden
a truck driver testifying about their injuries with a 702 inquiry into whether the device accurately
recorded their inputs on the day of the crash. This draft proposal also has the added benefit of
dropping the second sentence on simple scientific instruments, as it would not be necessary.
The machine-learning alternative is also preferable to the alternative on “ComputerGenerated Evidence,” which the Evidence Committee also discussed. 24 The agenda book analysis
is that “computer-generated is narrower than the “machine-generated” text provided by the
proposed rule, it does not specifically address the concerns associated with the use of machine
learning and artificial intelligence. Word processors, calculators, and digital cameras are all
examples of simple computers that would all be considered reliable.

B. Provide a definition to the rule’s application
If the Committee decides to proceed with the current version of the amendment, it should
provide a definition of “machine-generated” preferably in the text of the rule, but at a minimum,
in the Committee Note. As drafted, there is no definition of “machine-generated” provided in either
and the discussion of the proposed rule seems to indicate that it should be given a broad
interpretation, 25 thus resulting in much of AAJ’s objection to the rule.
Failing to provide a definition will result in courts applying the rule differently to the same
instruments and technology. Circuit splits and intra-district splits could immediately develop. It
would be better to limit the scope of the rule and be clear what the rule intends to cover. This will
avoid second-guessing by parties and courts, uneven application of the rules, and satellite
litigation.
C. Exempt routinely used instruments
The sentence to exclude simple scientific instruments would barely limit the number of
items that judges would have to evaluate. By using both the word “simple” and scientific” in the
caveat, the exception could even result in some parties questioning the reliability of date and
timestamp data from mobile phones and other electronic devices. At a minimum, both the rule text
and the Committee Note’s examples need to be crafted in a more sophisticated manner, as all these
examples are items that a court could take judicial notice of as reliable under Rule 201. Should the
Evidence Committee decide to move forward with a final rule, it would be beneficial to remove
the second sentence.
Alternatively, it may be clearer for both parties and courts to rewrite the second sentence
with the aim of exempting routinely relied upon instruments:
This rule does not apply to instruments routinely used to
produce [generate] the output.

The goal of the sentence is to create an exception for the output of instruments that are
routinely used (and expected to be used) for the function being measured, captured, or produced.
At its fall meeting, the Evidence Committee thought it should not cede coverage of the rule to the
general public, which this sentence would not do, as the court would still be required to evaluate
whether an instrument is routinely used. Machines that are routinely used but are not generally
used for the function employed would not be exempted. The word “generate” would be preferable
to the word “produce” only if the Evidence Committee adopts rule text other than “machinegenerated” evidence.
The corresponding paragraph in Committee Note could be rewritten to address both the
issues of routine use and some examples could look like this:

25

Id. at 143 (“‘Machine’ is defined as ‘an apparatus using or applying mechanical power and having several parts,
each with a definite function and together performing a particular task.’ So that term covers everything from fax
machines to bulldozers.”).

Page 9 of 10

The final sentence of the rule is intended to give trial courts
sufficient latitude to avoid unnecessary litigation over the
output from simple scientific instruments that are routinely
relied upon in everyday life. Examples might include the results
of a phone log, geolocation data, or other metadata. Moreover,
the rule does not apply when the court can take judicial notice
that the machine output is reliable. See Rule 201.

This exception also has the added benefit of functioning in tandem with instructions on judicial
notice.
V.

Conclusion

AAJ urges the Evidence Committee to reconsider what sort of rule is needed to address
concerns regarding machine learning and AI and focus on a rule to specifically address those
issues. The proposed rule applies to all sorts of machines that pose no reliability concerns and the
exemption for simple scientific instruments is far too limited. The committee should pause and
reevaluate how to draft a rule in light of the comments and testimony received. Thank you for
considering these comments. Please direct any questions to Susan Steinman, Senior Director of
Policy & Senior Counsel, at susan.steinman@justice.org.

Civil liberties, civil rights, and professional organizations are asking the Advisory Committee to reconsider
proposed FRE 707. It would apply to AI-generated evidence the rules of admissibility that currently apply to
expert witness testimony in existing rule of evidence, FRE 702. We point out that the appropriate criteria for
assessing the reliability of AI-generated evidence differ from the criteria in FRE 702 for assessing the reliability
of an expert witness’s testimony, making this an improper fit. The views of these organizations, ACM U.S.

Civil Rights, Civil Liberties, and Professional Organizations’ Joint Comment on Proposed
Federal Rule of Evidence 707 Concerning Admissibility of Machine-Generated Evidence
February 16, 2026
We are civil liberties, civil rights, and professional organizations that have engaged in policy
debates surrounding the use of artificial intelligence (AI) in various contexts. We are committed
to ensuring that AI use does not exacerbate societal bias and civil liberties threats.
The Advisory Committee has proposed a Federal Rule of Evidence 707 that would govern the
admissibility in federal courts of machine-generated information (which includes AI-generated
information) based on the reliability of that information. Courts’ decisions to admit or exclude AIgenerated evidence can result in wrongful incarceration as well as significant liability. For
example, use of AI-powered facial recognition systems has resulted in a number of wrongful
arrests. This is a high-risk use of AI, and demands exacting scrutiny.
The proposed rule would apply to AI-generated evidence the rules of admissibility that currently
apply to expert witness testimony in an existing rule of evidence, FRE 702. But the appropriate
criteria for assessing the reliability of AI-generated evidence differ from the criteria for assessing
the reliability of an expert witness’s testimony, making this an improper fit. For example, AIgenerated information is more reliable if the system that produced it was trained on unbiased
data of high quality. Nothing in Rule 702 assesses the training data, which instead focuses on
the knowledge and experience of the expert.
A rule governing the admissibility of AI-generated information in court proceedings is needed,
and the Advisory Committee, to its credit, has taken up this challenging task. While it has held
hearings and received testimony from a variety of witnesses with legal training, it has not yet
heard from certain technical experts and people steeped in AI policy-making who could help it
fashion a properly-focused rule. We urge the Committee to reconsider the text of the proposed
rule and to reach out to solicit additional input from a broader range of stakeholders. We would
welcome the opportunity to more fully participate in its efforts to develop a new rule of evidence
focused on AI-generated information.

Hon. Jesse Furman
Chair, Advisory Committee on the Rules of Evidence
Administrative Office of the United States
One Columbus Circle, NE
Washington, DC 20544
February 16, 2026
Dear Judge Furman and Advisory Committee Members,
We write on behalf of the Coalition for Prior Conviction Impeachment Reform, a group of eleven
professors who study Federal Rule of Evidence 609 and are convinced of the need to reform it.1
We know from our research and efforts that change is hard to achieve in the prior conviction
impeachment sphere. We therefore express our appreciation for the fact that after years of work
by the Reporter, Academic Liaison, Committee, and invited experts (including Coalition member
Jeffrey Bellin) a proposal has reached this stage. We write to support the proposed reform and to
make two suggestions.
We have voiced our support before, by means of a letter dated September 30, 2024, and
comments (written and oral) on our behalf from Coalition member Professor John Blume. We
will distill our main points under the headings of the two goals of the Federal Rules of Evidence
laid out in Rule 102: ascertaining truth and securing just determinations.2
The proposed amendment has the potential to limit the extent to which Federal Rule of Evidence
609(a)(1)(B) detracts from ascertaining the truth. As the members of our Coalition, among many
others, have long argued,3 this rule is antithetical to the truth-seeking mission of the Federal
Rules of Evidence for a host of reasons. For example, as we have described in previous
submissions, there is no evidence that prior convictions admitted under 609(a)(1)(B) have

as an Imperative, 99 B.U. L. Rev. 1873, 1879 (2019) (“[T]he goal of the Evidence Rules [is] to ascertain truth and
secure just determinations”).
3
See, e.g., Note, The Evidentiary Use of Constitutionally Defective Prior Convictions, 68 Colum. L. Rev. 1168,
1171 (1968) (describing as “widely recognized” the fact “that informing a jury of a prior conviction before they
retire to reach a verdict may lead to a less accurate factual determination,” particularly if it “deters the defendant
from testifying in his own behalf.”)

probative value on the question of a witness’s truthfulness.4 Social science data suggests, to the
contrary, that such prior convictions likely will not assist fact-finders in predicting a defendant’s
truthfulness.5 Yet, courts routinely admit prior convictions under the existing balancing test,
imagining against the dictates of both empirical evidence and logic that their probative value on
truthfulness outweighs the known and documented risk of unfair prejudice.6 Cases ending in
“wrongful convictions,” such as those studied by John Blume in his research into the effects of
prior conviction impeachment, bear out the causal relationship between the rule and catastrophic
failures in truth-seeking.7 Adding “substantially” to the balancing test will promote truth-seeking
if it corrects these misapplications and restrains judges from admitting prior convictions against
the accused.
Justice obviously is not served when rules of evidence point away from truth-seeking. But there
are additional ways in which Federal Rule of Evidence 609(a)(1)(B) detracts from the likelihood
of a just determination. These problems too, may be limited by the proposed amendment. First,
the American legal system is committed to procedural justice, a commitment that includes a
meaningful opportunity to speak.8 Yet the threat of prior conviction impeachment contributes to
the silence of the accused, including those with stories of innocence to tell.9 Those who exercise
their constitutional right to remain silent risk being penalized by jurors, despite instructions to
the contrary.10 Further, as has been detailed in many submissions, racial injustices are
compounded by prior conviction impeachment.11 And finally, prior conviction impeachment

evidence is predictably misused by jurors, despite instructions to the contrary.12 For example,
prior conviction impeachment lowers the burden of proof in close cases, denying the accused the
benefit of the beyond a reasonable doubt standard.13 It is our belief that the proposed
amendment, by limiting the impeachment of the accused in criminal cases, will go some way
towards aligning the Federal Rules of Evidence with their purported goal of promoting just
determinations.
In sum, the Coalition believes that this proposed rule is a step in the right direction.14 In light of
our research, the Committee’s discussions, and the Committee’s policy of tackling more than one
issue with a rule at the same time where possible,15 we make two suggestions:
Suggestion 1
The Reporter has detailed numerous examples of trial courts failing to honor the Federal Rule of
Evidence 609(a)(1)(B) balancing test. The record also suggests that a cause of those failures is
that trial judges lack incentives to conduct careful balancing.16 A central cause of this incentive
problem is judicially-imposed restrictions on the power to appeal an adverse ruling admitting
convictions under 609(a)(1)(B).17 Under Luce, the accused must testify in order to appeal such a
ruling. Post-Luce, Rule 609 appeals have “plummeted.”18 Under Ohler, the accused cannot
appeal such a ruling if he testifies about his prior convictions on direct. Without the ability to
introduce the convictions himself, the accused is unable to be candid with jurors about them, or
to frame or contextualize them. To preserve the right to appeal the trial judge’s admissibility
decision under Federal Rule of Evidence 609(a)(1)(B), the accused must instead wait for the
evidence to be raised by the prosecutor on cross, thus risking the inevitable jury inference that he
was hiding the evidence.
The structural barriers to prior conviction impeachment appeals brought about by Luce and
Ohler have created a vacuum of appellate regulation of trial courts as they conduct 609
is true today-saw a Black face when they thought about the criminal element in society.”); Anna Roberts & Julia

Coalition’s concerns about Rule 609 extend beyond the Rule 609(a)(1)(B) balancing test, and beyond the two
suggestions that we make, and we therefore hope that greater change will follow.

See Memorandum from Daniel J. Capra, Reporter, to Advisory Committee on Evidence Rules 37 (Apr. 1, 2025)
(“[T]he Committee’s policy has always been that if a rule is going to be amended, there might be improvements that
can—and should—be made even though those improvements are not enough to justify an amendment standing
alone. . . [I]f the Committee is going to amend a rule, that is a good time to make it the best it can be.”).

balancing. Insulated from review,19 trial courts have used their discretion to misapply the
balancing test and created the urgent need for the current proposed amendment. If the proposed
balancing test is to ameliorate the problems it seeks to address, these impediments to appellate
review should be tackled now.20
At least seventeen states have declined to follow Ohler.21 At least eleven states have declined to
adopt the Luce requirement that in order to preserve the right to appeal a prior conviction
impeachment ruling the accused must testify.22 While most of those eleven states developed that
stance through case law, Tennessee offers an example of a state that specifies in its version of Rule
609 that a decision not to testify does not destroy the ability to appeal a prior conviction
impeachment ruling:
If the court makes a final determination that [convictions are] admissible for impeachment
purposes, the accused need not actually testify at the trial to later challenge the propriety
of the determination.23

We urge the Committee to consider its ability to take steps to address these barriers to appeal and
the improper implementation of carefully crafted balancing tests that results.
Suggestion 2
When 609(a)(1)(B) is misapplied, the most obviously responsible party is the judge. The
proposed amendment targets that concern, sending a “signal” to judges.24
But every judicial decision to admit convictions that are similar to the charge at hand, needlessly
cumulative, inflammatory, or otherwise inappropriate, is preceded by a prosecutorial decision to
proffer at least that many convictions. As the Reporter puts it, sometimes the prosecution gets
“greedy.”25 The Committee might, in the spirit of addressing more than one issue at once,26
usefully send a signal on that front too.
In 2015, Rule of Civil Procedure 1 was amended “to emphasize that just as the court should
construe and administer these rules to secure the just, speedy, and inexpensive determination of
every action, so the parties share the responsibility to employ the rules in the same way.”27 By
analogy, if the courts have an obligation to strive for truth and justice in their application of the
rules of evidence, so too do prosecutors.
Prosecutors, indeed, have both an ethical and constitutional duty to do justice, in evidentiary as
in other spheres.28 Some have called for prosecutors to exercise restraint in the proffering of this
form of evidence,29 whose racial disparity is so stark,30 and whose misuse so likely.31

24

See Memorandum from Daniel J. Capra, Reporter, to Advisory Committee on Evidence Rules 17 (Oct. 1, 2024)
(“The argument in favor of the amendment is that a slight change to the balancing test can be a signal to courts that
they need to more carefully weigh prejudicial effect and probative value, and give defendants the protection that
Congress intended.”).
25
See Liesa Richter, District Court Rulings on Rule 609(a)(1)(B) Impeachment—2009–present 30 (case digest,
updated and with commentary by Daniel J. Capra) (Apr. 1, 2005) (“Comment: This is just a case in which the
government was greedy. They were already going to impeach the defendant with six automatically admissible
convictions. And yet they wanted to also impeach with a conviction that was similar to the crime charged. In these
circumstances, the argument that the conviction is necessary for, and will be limited to, impeachment, seems
disingenuous.”) (referring to United States v. Cunningham, 2012 WL 12865641 (W.D. Mich. 2012).

The Coalition thus suggests that the Committee include within the Committee Note a reminder
that prosecutors have a duty to do justice in this sphere.

Comment

I respectfully submit this comment in opposition to proposed Federal Rule of Evidence 707.
While the Rule aims to address challenges presented by AI‑generated and other machine‑generated
evidence, the proposal is unnecessary, impractical, and risks undermining the flexibility and fairness of the
existing evidentiary framework.

What is more, despite comments to the contrary, both plaintiffs’ attorneys and in‑house counsel—which
rarely align—oppose the Rule because courts have not struggled to manage machine‑generated outputs
under existing evidentiary rules. The proposal addresses a problem that’s not a problem while ignoring the
very real challenges facing the judiciary.
Indeed, Federal Rules of Evidence 702, 901, 902, and 403 already provide a robust structure for evaluating
expert‑like evidence, authenticating digital outputs, and excluding unreliable or prejudicial material. Legal
practitioners analyzing the proposal observe that courts are already capable of handling these issues case
by case, and that adopting a new rule now would be premature given the limited case law involving
AI‑generated evidence.
Due to the present state of federal and state budgets, Rule 707 also risks triggering unnecessary and
expensive satellite litigation over whether routine digital outputs require a full Rule 702 foundation. As one
analysis warns, the proposal could lead to “costly battles” over simple software printouts, turning ordinary
evidentiary questions into Daubert‑style disputes even when the output consists merely of raw data. This
risk of overreach would slow litigation and burden courts and parties alike.

Give Feedback

As recognized by both the National Institute of Standards and Technology as well as the International
Association of Chiefs of Police, the use of AI to produce an output that would carry criminal and/or civil
liability should be reviewed by a living person; who then adopts it. This living person would be subject to
cross examination and any output subject to the existing rules of admissibility.

Finally, the enactment of any such rule should be preceded with sufficient training to judges on artificial
intelligence, a condition not sufficiently met by federal and subsequent states that may enact such a rule.
Accordingly, the proposed Rule 707 is unnecessary, overly broad, and potentially harmful to both litigants
and the judicial system. Existing rules already provide sufficient safeguards.
I urge the Committee to decline adoption of Rule 707 and continue relying on the well‑established
evidentiary framework that has long served the courts.

Re:

Comments on Proposed New Fed. R. Evid. 707: Why A Modified Approach
to AI-Generated Evidence is Needed

Dear Advisory Committee members:
The undersigned 1 respectfully submit the following comments and suggestions regarding the
proposed introduction of a new federal rule of evidence (“Rule 707”) to address certain AIgenerated evidence (euphemistically called “machine-generated evidence”). The comments
supplement the oral testimony from Jonathan Redgrave, at the January 29, 2026, Advisory
Committee hearing.
Proposed Rule 707 represents a well-intentioned but flawed attempt to address the
admissibility of artificial intelligence-generated (“AI-generated”) content in federal court
proceedings. While the drafters sought to create a framework to guide judges and parties with
respect to evaluating and admitting AI-generated evidence, the rule as currently constructed fails
to achieve its stated objectives and instead creates a dangerous equivalence between AI outputs
and human expert testimony under Rule 702. As set forth in Section III, this equivalence is
inappropriate, scientifically unsound, and risks undermining the reliability standards that have long

protected the integrity of expert evidence in federal courts. Consequently, the Advisory Committee
should reject the current proposed rule.
At the same time, the undersigned recognize and agree with the Advisory Committee and a
minority of the comments that say that there is a need for action. Without additional guidance, we
respectfully predict that courts will be confronted with a morass of potential uses of AI-generated
outputs that either directly or indirectly impact expert witness testimony. This, in turn, will create
a situation where conflicting approaches adopted in good faith by different judges in different
jurisdictions will emerge and result in drastically different outcomes based on the admission or
exclusion of AI-generated outputs. Such divergence will negatively impact the predictability of
proceedings, destabilizing the basic tenets of fairness and justice that undergird the criminal and
civil rules of procedure. 2
Fortunately, we believe that a viable alternative approach exists. Under this alternative
framework, AI would be treated as a tool, not a witness, while remaining admissible as fact
evidence when proper foundation is established pursuant to the existing rules. As such, in addition
to rejecting the current rule, the Advisory Committee should draft a new one that: (1) prohibits AI
outputs from serving as expert testimony altogether; (2) recognizes that experts may appropriately
rely on AI tools in forming their opinions, provided they can establish the reliability of that reliance
under existing Rule 702 factors; and (3) acknowledges that AI-generated content may be
admissible as ordinary fact evidence when relevant and properly authenticated under Rules 401,
403, and 901. Our proposed alternative to the current rule that would accomplish these goals is
set forth for consideration in Section II and the reasoning behind our proposal is set forth in Section
IV. Finally, our view on other proposed rules addressing AI-generated outputs and evidence can
be found in Section V.
I.

The Need to Pause for Reflection and Refinement

By our count, a significant majority of commentators have urged the Advisory Committee to
slow down and refine the proposed rule before adoption. 3 Common themes among those urging
delay include:

2

•

The alleged problem may not actually exist (no cases found where AI was offered without
an expert);

•

Existing rules (702, 901, 902) may be adequate;

See, e.g., Submission from Washington Legal Foundation (https://www.regulations.gov/comment/USC-RULES-EV2025-0034-0042).
3
See, e.g., Submission from Lawyers for Civil Justice, at 10 (https://www.regulations.gov/comment/USC-RULESEV-2025-0034-0013) (arguing that “the need for an appropriate rule vastly outweighs the utility of an immediate rule”
and that “an incomplete or inadequate rule is certain to cause more harm than allowing courts to address emerging
issues as the Advisory Committee works to refine its proposal”).

J. Redgrave, B. Redgrave, and T. Redgrave Comment on Proposed Rule 707
February 16, 2026
Page 3
•

The rule is overly broad and vague;

•

Technology is changing too rapidly;

•

More judicial experience is needed before codifying; and

•

The risk of unintended consequences.

The Advisory Committee itself acknowledged “the limits of its expertise on matters of technology
and deemed public comment as the best way to obtain the necessary information to support or
reject the rule.” Advisory Committee on Rules of Practice and Procedure, Agenda Book at 59
(June 10, 2025) (explaining that the Advisory Committee expects to “receive critically important
information during the public comment period about the need for this new rule”).
At the same time, certain commentators endorsed the work of the Advisory Committee and
suggest the rule should move forward. 4 Many of the commentators in this cohort noted that judges
are already equipped with significant guidance and discretion under the existing evidence rules,
including the recently amended Fed. R. Evid. 702, to appropriately manage issues that may arise
with respect to computer-generated evidence. These commentators specifically endorse the
Advisory Committee’s use of Rule 702 as the anchor for the new rule.
While the outcome in rulemaking should not be driven by a “popular vote,” the contrast in
opinions and submissions is stark. One of the undersigned, Jonathan Redgrave, has been an
observer or participant in the federal judiciary’s rulemaking processes (primarily proposed civil
and evidence rules) for more than 25 years and cannot recall a time when the divergence in views
on a proposed rule was so significant irrespective of traditional advocacy positions (e.g., typical
“plaintiffs” v. “defendants,” “patient” v “provider,” or “employees” v. “employers”). In addition,
the groundswell of comments towards the end of the comment period suggests to us that AIgenerated evidentiary issues and proposed Rule 707 itself have only garnered significant attention
outside of the Advisory Committee in the later stages of the rulemaking process to date. While
that reality may be unfortunate (and potentially frustrating) given the significant undertaking by
the Advisory Committee to draft and publish a proposed rule, we urge the Advisory Committee to
step back with enough space to consider and address the comments that are being submitted from
various viewpoints across the litigation spectrum (criminal and civil) and obtain more feedback on
alternative rule proposals—though the reset in the rulemaking process need not be elongated or
abandoned.

4

Paradoxically, some of these same commentators also suggested modifications that likely would require republication
under the rulemaking process.

Proposed Alternative Federal Rule of Evidence 707: AI-Generated Evidence 5

Consistent with the foregoing plea for caution, we believe the alternative rule set forth below
is a workable framework that could be vetted with republication of the proposed rule within the
next rulemaking cycle, and we urge the Advisory Committee to do so.
Rule 707: Expert Testimony Considering or Relying on Artificial Intelligence System
Outputs
(a) Definitions. For purposes of this rule, “Artificial Intelligence System” refers to
any computational model, machine learning algorithm, or similar automated tool or
process that produces outputs based on pattern recognition, prediction, or data
analysis, and as it comes from a machine and not a person, is not capable of taking
an oath, being cross-examined, or providing specialized knowledge in the manner
contemplated by Rule 702.
(b) Expert Testimony by Artificial Intelligence Systems Prohibited. No outputs
generated by an Artificial Intelligence System shall be admitted as expert testimony
under Rule 702 or otherwise. Artificial Intelligence System outputs may not serve
as substitutes for human expert witnesses and may not be offered as opinions
requiring specialized knowledge, skill, experience, training, or education.
(c) Expert Use of Artificial Intelligence Systems Permitted. An expert witness
may consider or rely on outputs of Artificial Intelligence Systems in forming their
opinions, provided that:
(1) the expert independently satisfies the requirements of Rule 702(a)–(d)
with respect to their own testimony;
(2) the expert demonstrates the reliability of the Artificial Intelligence
System for the specific task, including providing appropriate foundation,
qualified by knowledge, training, and experience, for the reliability,
transparency, interpretability, and validation of the Artificial Intelligence
System and its outputs generally and as applied to the facts of the case; and
(3) the expert is able to explain their methodology, reasoning, and the
factual basis for their consideration and/or reliance on the Artificial

5

While we acknowledge that there is a great divergence in various alternatives proposed by different commentators
and the Advisory Committee itself, we have developed a rubric that draws inspiration primarily (but not exclusively)
from the Advisory Committee’s prior work, the oral testimony of Prof. Roth (January 29, 2026) and her accompanying
January 15, 2026 letter summary of her testimony, the submission of the Federal Courts Committee of the New York
City Bar Association (https://www.regulations.gov/comment/USC-RULES-EV-2025-0034-0046), and the submission
of Lawyers for Civil Justice (https://www.regulations.gov/comment/USC-RULES-EV-2025-0034-0013).

Intelligence System.
(d) Artificial Intelligence System Outputs as Fact Evidence. Artificial
Intelligence System outputs may be admitted as ordinary fact evidence when
relevant and properly authenticated under Rules 401, 403, and 901. The party
offering such evidence must establish its authenticity and relevance, and the court
must ensure that the probative value is not substantially outweighed by any risk of
unfair prejudice, confusion, or misleading the jury. Depending on the proposed use
of the Artificial Intelligence System Outputs, the foundation may necessitate human
testimony, qualified by knowledge, training, and experience, for the reliability,
transparency, interpretability, and validation of the Artificial Intelligence System
and its outputs generally and as applied to the facts of the case. In such
circumstances, the testimony does not convert the output into expert testimony that
is prohibited under subsection (b) and serves only to authenticate and provide
context for the fact evidence being offered.
(e) No Impact on Other Computer or Machine Generated Outputs as Fact
Evidence. Any other types of outputs from computers or other mechanical and/or
electrical devices may be admitted as ordinary fact evidence when relevant and
properly authenticated under Rules 401, 403, and 901. The party offering such
evidence must establish its authenticity and relevance, and the court must ensure
that the probative value is not substantially outweighed by any risk of unfair
prejudice, confusion, or misleading the jury.
III.

Problems with Current Proposed Rule 707

The Advisory Committee should reject the current proposed Rule 707 in favor of one that
prohibits the use of AI-generated outputs as expert testimony because the current rule: (1) creates
a false equivalence between AI-generated outputs and human expert testimony under Rule 702;
and (2) ignores the “black box” problem inherent in current AI systems.
A.

The False Equivalence Problem

The central flaw of proposed Rule 707 is its implicit suggestion that AI-generated outputs can
serve as a direct substitute for human expert testimony under Rule 702. This approach
fundamentally misunderstands both the nature of modern AI systems and the role of expert
witnesses in adversarial proceedings. Rule 702 permits expert testimony when specialized
knowledge will assist the trier of fact but requires that such testimony rest on a sufficient factual
basis, be the product of reliable principles and methods, and reflect a reliable application of those
principles to the facts of the case. Critically, human experts can be cross-examined about their
methodology, their reasoning process, and the basis for their conclusions. They can explain gaps

in their analysis, acknowledge limitations, and adjust their opinions when confronted with new
information. 6
AI systems, by contrast, cannot perform any of these testimonial functions. They cannot take
an oath, be cross-examined, or reliably explain their reasoning in any meaningful way. 7 More
fundamentally, they are unable to meaningfully possess and reliably employ the specialized
knowledge that Rule 702 contemplates. Core to contemporary AI systems are models that are
trained on observed data to approximate the unknown probability distribution representing the
underlying data generating processes. AI systems use these internal models to calculate the
likelihood/probability of each possible outcome based on the given input and then use these
likelihoods/probabilities for tasks such as prediction or generation. Because of the probabilistic
nature of this construction, AI systems do not know specific facts but instead have probabilistically
informed “beliefs” or positions. 8 Exacerbating this epistemic failure, even when the output of AI
systems may be correct or initially mirror that of a human expert, minor semantic or contextual
changes 9 can often cause them to adopt an incorrect position, thereby demonstrating a lack of
(robust) informed deterministic reasoning. 10 Perhaps most problematically, it has been shown that
(language) models are guaranteed to produce hallucinations, even within an ideal scenario. 11
These unavoidable flaws significantly hinder the ability of AI systems to meet the reliability
requirements of Rule 702.

6

Recent research indicates AI’s shortcomings in these areas may be one of the primary causes of AI hallucinations
See, e.g., Why Language Models Hallucinate (https://doi.org/10.48550/arXiv.2509.04664).
7
Efforts to use AI models to explain themselves through “chain of thought” or so called “reasoning” models has been
shown to be wholly insufficient, with models often providing misleading or incorrect explanations of their own
behavior and even going as far as to obfuscate their reasoning when penalized. See, e.g., Reasoning Models Don't
Always Say What They Think (https://doi.org/10.48550/arXiv.2505.05410); Monitoring Reasoning Models for
Misbehavior and the Risks of Promoting Obfuscation (https://doi.org/10.48550/arXiv.2503.11926). For additional
criticism of these terms broadly see Stop Anthropomorphizing Intermediate Tokens as Reasoning/Thinking Traces!
(https://doi.org/10.48550/arXiv.2504.09762).
8
A troubling corollary of this result is that AI systems are incapable of categorically distinguishing between facts and
belief.
See, e.g., Language Models Cannot Reliably Distinguish Belief From Knowledge and Fact
(https://doi.org/10.1038/s42256-025-01113-8).
9
See, e.g., Illusions of Confidence? Diagnosing LLM Truthfulness via Neighborhood Consistency
(https://doi.org/10.48550/arXiv.2601.05905) and Representational and Behavioral Stability of Truth in Large
Language Models (https://doi.org/10.48550/arXiv.2511.19166).
10
Ironically, indicating that the user prompting the AI system is an expert can exacerbate this issue. See, e.g.,
Epistemic Fragility in Large Language Models: Prompt Framing Systematically Modulates Misinformation
Correction (https://doi.org/10.48550/arXiv.2511.22746). Adding insult to injury, recent work indicates that even when
models encode a correct response, they may generate a false one (even without perturbing the input or context). See,
e.g., LLMs Know More Than They Show: On the Intrinsic Representation of LLM Hallucinations

The Advisory Committee itself acknowledged these concerns in its explanatory materials,
noting worries about “analytical error or incompleteness; inaccuracy or bias built into the
underlying data or formulas; and lack of interpretability of the machine’s process.” Advisory
Committee on Rules of Practice and Procedure, Agenda Book at 75 (June 10, 2025) (listing
concerns with machine-generated evidence). The Advisory Committee further recognized that
“[t]he hearsay rule is likely to be inapplicable because . . . a machine cannot be cross-examined.”
Id. at 58. Yet despite acknowledging these fundamental problems, the proposed rule does not
address them adequately. 12
B.

The Black Box Dilemma and Interpretability

Perhaps more problematic is the inherent opacity of modern AI systems—what researchers call
the “black box” problem. When a neural network with billions or trillions of parameters generates
an output, even its creators typically cannot trace the specific pathway of reasoning that produced
that result. 13 While efforts to advance AI interpretability is a increasingly active area of research,
and multiple paradigms for understanding models through various lenses have been developed, the
field remains in its infancy; researchers can sometimes identify high-level patterns or features that
influence AI behavior but cannot reliably explain why a particular input produced a particular
output in any given instance. 14
This opacity is fundamentally incompatible with the reliability requirements of Rule 702. Rule
702 and its supporting case law require courts to evaluate whether an expert’s methodology is
scientifically valid and properly applied. How can a court perform this gatekeeping function, or
opposing counsel effectively cross-examine an AI output, when no one—not the offering party,
not the system’s designers, not leading researchers in the field—can reliably explain the inferential
steps that produced it? The answer is that they cannot. Proposed Rule 707’s failure to grapple
with this reality renders it inadequate as a framework for admissibility and should be rejected.
IV.

Reasoning Behind the Proposed Alternative Approach

In addition to adopting a rule that prohibits the use of AI outputs as expert testimony, the
Advisory Committee should adopt a rule that frames AI as a tool rather than a witness while
allowing AI-generated content to be admissible as fact evidence when proper foundation is
established under the existing rules.

The Appropriate Framework: AI as Tool, Not Witness

A sounder approach to current proposed Rule 707 would recognize AI for what it is: a
potentially useful tool that experts may rely upon, but not a substitute for human expertise. Under
Rule 703, experts may base their opinions on facts or data that are not themselves admissible,
provided those facts or data are of a type reasonably relied upon by experts in the field. If an
epidemiologist uses AI to analyze patterns in disease transmission data, or a financial expert
employs machine learning to detect fraud patterns, these are legitimate uses of technology as an
analytical aid. But the expert—not the AI—must render the opinion and stand behind it.
Under this approach, for such reliance to be appropriate, the expert must satisfy the Rule
702(a)–(d) factors regarding their use of AI. Specifically, the expert must demonstrate that: (a)
their use of the AI tool will help the trier of fact; (b) they possess the qualifications to evaluate and
interpret the AI tool’s outputs; (c) their testimony rests on a sufficient basis, including validation
of the AI tool’s reliability for the specific task; and (d) they have reliably applied the AI
methodology to the case facts. This framework preserves judicial gatekeeping while allowing
experts to leverage technological tools where appropriate.
B.

AI-Generated Content as Fact Evidence: A Workable Alternative Under Existing
Rules

Separately, certain AI-generated content can and should be admissible as fact evidence when
proper foundation is established. No new rule is required to accomplish this, however: if a litigant
seeks to introduce AI-generated communications, documents, or other outputs not as expert
opinion but as facts relevant to the case, the traditional evidence rules provide adequate safeguards.
Under Rules 401 and 403, such evidence must be relevant, and its probative value must not be
substantially outweighed by unfair prejudice or confusion. Authentication requirements under
Rule 901 ensure that the evidence is what its proponent claims. Business records and other hearsay
exceptions may apply where appropriate foundations are laid.
For example, if the issue is whether a company deployed an AI chatbot that made false
representations to consumers, the chatbot's outputs are admissible as fact evidence of what
representations were made—not because the AI is testifying, but because those outputs are relevant
facts in the case. Similarly, AI-generated content may be relevant to show a party’s reliance on AI
advice, or the state of AI technology at a relevant time. In these scenarios, the AI-generated output
is simply evidence like any other document or business record, subject to the ordinary rules of
authentication, relevance, hearsay, and prejudice.

Proposed Alternative Rule 707 Does Not Require Separate Disclosure or
Coordination with Civil Rules

During the public comment process, including testimony, there was a spirited debate regarding
the need for additional pre-trial disclosures of AI-generated evidence that potentially would be
offered as “freestanding” expert opinion. That concern is real under the rubric of the current
proposed Rule 707 and should not be resolved solely by reliance on proper case management.
Under our proposed alternative, however, there is no need for disclosure because the AI-generated
content, standing alone, can never be offered directly or indirectly as an “expert opinion” that
would need a separate disclosure regime. 15 Of course, to the extent that a disclosed human expert
is considering or relying on AI-generated outputs to form or support the opinion being proffered,
then we expect that the rigor of existing Rule 702 will be applied to such proposed use.
V.

Thoughts on Other Rules Addressing AI-Generated Outputs

Finally, we concur with submissions that recommend a go-forward approach to broader
rulemaking to account for the current and likely future impact of AI-generated outputs on civil and
criminal matters. 16 The issues surrounding “deep fakes” alone warrant rulemaking, but so do other
considerations such as potential pre-trial disclosures regarding AI-generated content use in
connection with civil and criminal litigation and other potential refinements to evidence rules
regarding Hearsay (Article 8), Authentication and Identification (Article 9), and Contents of
Writings, Recordings, and Photographs (Article 10). Concurrent with a republication of a revised
proposed Rule 707 we recommend that the Committee on Rules of Practice and Procedure
establish a working group among the five advisory committees that can focus on these other areas
as well as obtain more feedback from judges, lawyers, and litigants with respect to whether AIgenerated outputs that are not within the scope of any enacted Rule 707 are being excluded or
admitted into evidence under other rules that creates inconsistent, unfair, or unjust results. Finally,
to the extent the Advisory Committee intends to publish a proposed rule on “deep fakes,” we
recommend publishing that rule together with the republication of proposed Rule 707—as well as
any other proposed civil and criminal rules that address similar subject matter—and posit that
packaging the rules in this coordinated manner will elicit public feedback in a way that is more

15

The NYC Bar Association takes a different view, recommending that no evidence rule be adopted without
corresponding revisions to Civil Rule 26 and Criminal Rule 16 to incorporate AI-specific discovery mechanisms. See
Submission of the Federal Courts Committee of the New York City Bar Association at 3–4
(https://www.regulations.gov/comment/USC-RULES-EV-2025-0034-0046). While that concern is well-taken under
the current proposed Rule 707—which would permit freestanding AI outputs as quasi-expert testimony without any
expert disclosure obligation—our proposed alternative substantially eliminates the gap by requiring that AI outputs
offered as expert-level analysis always be accompanied by a disclosed human expert subject to Rule 26(a)(2).
16
See, e.g., Submission from Hon. Paul Grimm (ret.) and Prof. Maura Grossman
(https://www.regulations.gov/comment/USC-RULES-EV-2025-0034-0021); Submission of Hon. John Facciola
(ret.)(https://www.regulations.gov/comment/USC-RULES-EV-2025-0034-0025).

respectful of both the Advisory Committees’ views on avoiding too frequent rule changes, and the
courts and parties that will need to implement any newly adopted rules.
CONCLUSION
We respectfully submit that current Proposed Rule 707 fails to provide a proper framework in
practice because it conflates three distinct categories of AI-generated evidence and creates an
inappropriate pathway for AI outputs to serve as expert testimony, either directly or indirectly. The
rule should be revised to clearly prohibit the introduction of AI-generated outputs as a substitute
for human expert witnesses under Rule 702. At the same time, it should recognize that experts
may appropriately rely on AI tools in forming their opinions, provided they can establish the
reliability of that reliance under existing Rule 702 factors. Finally, the rule should acknowledge
that AI-generated content may be admissible as ordinary fact evidence when relevant and properly
authenticated under Rules 401, 403, and 901. This tripartite framework respects both the potential
utility of AI technology and the fundamental requirements of reliability, transparency, and
adversarial testing that underpin our evidence system. Until such revisions are made, Rule 707 in
its current form should be rejected as inconsistent with the scientific and legal principles it purports
to serve.
Thank you again for the opportunity to submit our comments and suggestions on the proposed
rule.

Re: Federal Rule of Evidence Rule 707
Comments on Proposed Amendment
Dear Honorable Committee Members:
The purpose of this letter is to comment briefly on proposed amendment to Federal Rule
of Evidence 707. I am an attorney in Virginia in private practice who for the past 38 years has
represented plaintiffs exclusively. Most of my cases now focus on admiralty and maritime law;
thus, many of the cases are filed in various federal courts in districts across the country. In the
past, I represented plaintiffs for diverse types of personal injury claims and for discrimination
claims when the discrimination affected large groups of people. My practice also included
participation in the BP Oil Spill Multi-District Litigation. Accordingly, I have experience with
admissibility of evidence under the 700-series of the Federal Rules of Evidence. I have read the
text of the proposed amendment to Rule 707, the comments posted about the proposed amendment,
and the hearing testimony.
The main reason I feel the need to comment on proposed amendments to Rule 707 is
because I found it overly broad, ambiguous and confusing. Although it is difficult to fashion clear,
concise rules of court, the Rules of Evidence should be clear enough to be workable. I believe the
proposed amendment to Rule 707 needs more work to reach that level. Please reconsider the
amendments in view of the excellent observations and suggestions made in comments filed with
the Committee and by witnesses who testified in person at the hearings held about Rule 707. I do
not believe the amendment should be adopted as written.
The Committee would be wise to include in an amendment to Rule 707 more definitional
clarity. For example, definitions of “machine generated evidence” and of “basic scientific
instruments” would provide more clarity to language that is currently vague and ambiguous. At
this point it seems overly broad. Litigants have long employed as evidence machine generated
data maintained in the ordinary course of business and should be allowed to continue that practice.
The test for admissibility is clear, and courts and litigants have long relied on the certainty
generated by the rules. My concern is that the new language will make previously admissible
evidence inadmissible.

Fortunately, or unfortunately, the technological advances we are experiencing in society
today – the age of Artificial Intelligence - created a need for the Committee to consider amending
the Rules of Evidence. As the Committee pointed out in its comments to the Rule, Artificial
Intelligence has created a new category of information, because the information now can rise to
the level of opinion in the past provided only by human beings. The Committee is wise to consider
computer generated opinions in context of the Rules of Evidence to determine whether the existing
rules are sufficient.
The proposed amendment has been the subject of extensive comment in the record. It is
interesting to note that nearly every commentator from every perspective urges the Committee to
withhold adoption of the proposal and give it further consideration. I agree. I will not write
extensive comments because of redundancy, but support those in the record made by Steve Herman
and Tad Thomas.
Accordingly, I respectfully request the Committee table the amendment to Rule 707 and
continue to work with the public to fashion one or more workable rules or have further discussion
about whether an amendment is needed.
Respectfully,
Deborah C. Waters

The Honorable Jesse M. Furman, Committee Chair
Professor Daniel Capra, Reporter
Members of the Advisory Committee on the Evidence Rules

February 16, 2026
Submitted online
Re: Proposed Federal Rule of Evidence 707
Dear Judge Furman, Professor Capra, and Members of the Advisory Committee on
Evidence Rules:
The National Association of Criminal Defense Lawyers (NACDL) is pleased to
submit our comments on the proposed new Federal Rule of Evidence 707. Our
organization has a nationwide membership of thousands of direct members, and up
to 40,000 other members through state affiliates. NACDL’s members include private
criminal defense attorneys, public defenders, military defense counsel, law
professors, and judges. The majority of our members are trial lawyers who are
regularly litigating in both state and federal courts around the country. Thus,
NACDL is in a unique position of having input from the ongoing experiences of
lawyers with substantial experience with the challenges posed by artificial
intelligence and other machine-generated evidence. Currently, NACDL’s Fourth
Amendment Center is litigating technologies that include, but are not limited to,
automated license plate readers, geo-fence warrants, mass cell-site location
information, facial recognition technology, ShotSpotter, and forensic genetic
genealogy.
I.

Introduction

Given our organization’s experience with these issues, we are keenly aware that
“machine-generated evidence” and how courts should address it are important to both
the general public and the law. While NACDL is pleased that the Advisory Committee
on Evidence Rules (“Advisory Committee”) is taking steps to address this emerging
area of the law, we have concerns about the proposed FRE 707 (P.F.R.E 707) as
currently written and encourage the Advisory Committee to pause before adopting it.

Given the quick pace of technological change, a pause would give the Advisory
Committee ample time to consider the ramifications of this proposed rule, it's impact
in our courtrooms around the country and on determinations that affect life and
liberty.
If the Advisory Committee is inclined to move forward with the proposed rule
at this time, NACDL would like to offer suggestions to clarify the rule and ensure
that it accurately reflects the Advisory Committee's intent.
II.

The Advisory Committee should pause before moving forward with this
proposal at this time.

History shows us that technology evolves faster than the law can keep up.
Since the Advisory Committee began considering an amendment to address machinegenerated evidence, it has been keenly aware that this technology has been evolving
rapidly. Private companies currently developing artificial intelligence (AI) systems
claim uncertainty about AI consciousness1, while scholars caution that
anthropomorphizing these technologies “serves to obscure the actions and
accountability of people building and using the systems”.2 We simply do not yet know
how these technologies will be presented in court. As other commentators have noted,
the rule, as currently proposed, raises serious issues about applicability and
feasibility. Adopting this rule, as written, at this time, risks cementing outdated
technological concepts in the Federal Rules of Evidence. Considering that the
Advisory Committee disfavors amending the same rules multiple years in a row,
adopting this proposal would leave federal practitioners with an outdated rule for
several years.3

Additionally, states have historically adopted the Federal Rules of Evidence into
their own evidence rules.4 Adopting proposed Rule 707 now would compound the
problem and leave states with a rule that is difficult to modify as technology evolves.
For these reasons, NACDL urges the Advisory Committee to act with caution before
promulgating any amendment on machine-generated evidence.
III.
A.

If the Advisory Committee elects to go forward with promulgating a rule,
NACDL would like to raise the following areas of concern:
This rule risks subsuming the Federal Rule of Evidence 702.

The current text of P.F.R.E 707 assumes that evidence will be presented
without an expert. It doesn’t require expert testimony but rather explicitly envisions
and creates a situation that governs the admissibility of evidence without experts.
Lawyers for Civil Justice has called this a “pathway for admission” in their comments
to the Advisory Committee. The presumption underlying the rule is that evidence will
be presented in court by non-expert witnesses. The rule provides that, in this
scenario, a judge must determine whether the evidence presented meets the
requirements of F.R.E. 702 without the assistance of an expert witness. The rule
incentivizes the removal of experts from the trial process altogether.
A major consideration for governmental agencies, including investigative
agencies and prosecutors, is cost reduction. The logic of efficiency and convenience
often undergirds the introduction of technology and tech solutions. The logic of costcutting is likely to apply to the expensive process of hiring expert witnesses. While
the rule is not intended to encourage parties to opt for machine-generated evidence
over expert witnesses, such a rule would inevitably result in encouraging cutting the
cost of expert witnesses in favor of machine-generated evidence and lay witnesses.
Experts are vital where technology is concerned, particularly in the criminal legal
system, where technologies known to produce unreliable results often continue to be
used. Where novel technologies are concerned, experts become even more important.
For example, new complex technologies like AI applications are not created by
a single person “possessing personal knowledge of all the facts that are needed to

4At this writing, Arizona, Kentucky, Louisiana, Michigan, and Ohio have adopted their own rules on expert

testimony to match the amendment to Rule 702, which was made effective in December 1, 2023.

demonstrate that the technology and its output are what its proponent claims them
to be. Data scientists may be required to describe the data used to train the AI system.
Developers may be required to explain the features and weights that were chosen for
the machine-learning algorithm.” (Grimm, Grossman, and Cormack) 5. Witnesses who
operate these technologies, or lay witnesses who present the result and output in
court, are likely to have limited knowledge as to how they are created and the testing
that measures their reliability. When such witnesses present evidence, the burden is
likely to fall on defense counsel to challenge the reliability of the technology. This
extra burden disproportionately affects under-resourced individuals and places a
heavy burden on public defenders, who regularly face budgetary crises and may not
have the resources to retain experts for every criminal case.
B.

Instead of reversion to F.R.E. 702, proposed F.R.E. 707 should include
the factors outlined in F.R.E 702(a)-(d) with modifications more
appropriate to evidence instead of human expert analysis.

Proposed F.R.E. 707, which contemplates the types of evidence produced by
some kind of scientific, machine, or computing process, would better be served by
modifying the factors contained in F.R.E. 702 to properly apply to any such evidence
admitted through either an expert or a lay person.
While there is still danger inherent in creating a rule that allows evidence to
be admitted which should require an expert 6, if this rule change does go forward,
proposed F.R.E. 707 should not simply refer back to the factors of F.R.E. 702, as 702
applies to evaluation of a human expert – not a computational output. As such,
Proposed F.R.E. 707 should spell out with specificity the type of evaluation courts
should apply when acting as the gatekeepers of the admission of such evidence.

6 Committee Note acknowledges that this rule does not intend to discourage expert testimony, nor does it anticipate

that those intending to introduce such evidence without an expert will be able to overcome the hurdle of the analysis
required by this rule. With this being the case, it would seethe m that such a rule is indeed unnecessary and that any
such evidence should require an expert or be otherwise entered through stipulation. See Committee Note, at 61-73,

F.R.E. 702 provides a good foundation for the types of inquiries the court must
make but runs into hurdles when applied to a computational output. The Committee
Note, at 48-55, states the following:
The rule applies when machine-generated evidence is entered directly,
but also when it is accompanied by lay testimony. For example, the
technician who enters a question and prints out the answer might
have no expertise on the validity of the output. Rule 707 would
require the proponent to make the same kind of showing of reliability
as would be required when an expert testifies on the basis of machinegenerated information.
The Advisory Committee is indeed addressing the right concerns about the
attempts to admit computer-generated outputs through lay witnesses; however, the
proposed evaluation of this evidence type through F.R.E. 702(a)-(d) by the courts
requires refinement. Taking the example of the lay technician who does not have the
requisite expertise in the validity of the output, the rule does not explain how the
technician, or the party seeking to admit the evidence, should apply the factors in
702(a)-(d) to make a showing of reliability as it relates to the generated output they
seek to admit.
The factors in F.R.E. 702(a)-(d) state the following:
A witness who is qualified as an expert by knowledge, skill, experience,
training, or education may testify in the form of an opinion or otherwise if the
proponent demonstrates to the court that it is more likely than not that:
(a) the expert’s scientific, technical, or other specialized knowledge will help
the trier of fact to understand the evidence or to determine a fact in issue;
(b) the testimony is based on sufficient facts or data;
(c) the testimony is the product of reliable principles and methods; and
(d) the expert's opinion reflects a reliable application of the principles and
methods to the facts of the case.
Those factors assume that there is a person who intends to admit the evidence
and who has specialized knowledge to answer the questions posed in the evaluation

of the evidence. Further, what kinds of information would the courts need to see to
feel comfortable that the computer-generated outputs are not only reliable but also
could be properly understood by the fact-finders if presented by such a lay technician?
The Committee Note provides some examples but does not entirely contemplate the
problem of how such information would be produced and conveyed. Who would
produce and explain evidence relating to the training data sets used by the
algorithmic program in question? What kinds of reliability data would be provided
and by whom? Ultimately, it seems that it would be impossible for any lay witness to
meet the standards anticipated by this rule and such evidence would require some
form of expert testimony.
C.

Clarity of terms is necessary because the term “machine-generated” is
so broad that it would apply to most evidence introduced in courts today.

As other commenters have noted, the term “machine-generated” is so broad as
to apply to a huge array of evidence being introduced in the criminal legal system.
Because of the broadness of the term, P.F.R.E. 707 risks becoming the default for
admission of evidence that is generated by machines, is the output of machines, or
even has machines involved in the process at any step. Any rule attempting to define
evidence that is the result of a computational or scientific process should use
industry-standard terminology that is widely accepted and understood.
1. The addition of language intending to exclude “the output
of simple scientific instruments” as a means of clarity and
efficiency, instead creates further confusion about the
application of this rule.
The text of the proposed rule includes a caveat relating to the “output of simple
scientific instruments” in an attempt to define the types of evidence the rule seeks to
apply to and avoid unnecessary litigation in the courts. While the Advisory
Committee note provides examples of what a “simple scientific instrument” might
constitute7
