UNITED STATES DISTRICT COURT
EASTERN DISTRICT OF LOUISIANA

FREDERICK E. ADDISON, SR., ET AL., CIVIL DOCKET
Plaintiffs

VERSUS NO. 19-11133
c/w 19-14512

LOUISIANA REGIONAL LANDFILL SECTION: “E” (5)
COMPANY, ET AL.,
Defendants

Applies to: Both Cases

ORDER AND REASONS
Before the Court are two contested Motions in Limine filed by Plaintiffs1 and
Defendant Jefferson Parish2 (collectively, the “Movants”), both seeking to exclude
testimony of Barry Kline, P.E., a purported expert on landfill gas collection and control,
retained by Defendant Aptim Corporation (“Aptim”). Aptim filed memoranda in
opposition.3 The Movants filed reply memoranda in support of their respective Motions
in Limine.4
BACKGROUND
This case concerns the operation of the Jefferson Parish Landfill in Waggaman,
Louisiana (the “Landfill”), and the resulting odors emitted from the Landfill between July
1, 2017, and December 31, 2019 (the “relevant time period”). Plaintiffs, who are Jefferson
Parish residents, filed several individual lawsuits that were consolidated into a mass
action, Addison v. Louisiana Regional Landfill Co., which contains over 500 individual

4 R. Doc. 613 (Plaintiffs’ reply); R. Doc. 631 (Jefferson Parish’s reply).
Plaintiffs.5 Plaintiffs assert negligence and nuisance claims under Louisiana state law6
against Defendants: Jefferson Parish, which owns and contracts with others to operate
the Landfill; Aptim Corporation, which managed the gas and leachate collection systems
of the Landfill from July 2017 to May 2019; and three entities that operated the Landfill
from May 2013 to December 2020: Louisiana Regional Landfill Company;7 Waste

Connections Bayou, Inc.;8 and Waste Connections US, Inc.9
On November 5, 2019, the Court issued the first Case Management Order (“CMO”),
which established a bifurcated litigation schedule under which the issue of general
causation would be resolved first.10 The Court held a trial on general causation in early
2022.11 On November 29, 2022, the Court issued its Findings of Fact and Conclusions of
Law as to General Causation (the “General Causation Order”),12 determining that, during
the relevant time period: (1) odors and gases were emitted by the Landfill;13 (2) the
emissions of gases and odors from the Landfill occurred during the relevant time period;14
and (3) exposure to the odors and gases emitted by the Landfill at a level of five parts per
billion for thirty minutes “is sufficient by itself for individuals generally to be able to smell
hydrogen sulfide and for the exposure to cause a reaction.”15 Having found that Plaintiffs

established general causation for certain Allowed Injuries, the Court ordered that a trial

be conducted with a select number of Addison Plaintiffs (the “Trial Plaintiffs”).16 The first
Addison trial was set to begin on September 5, 2023,17 and has since been continued to
begin on August 12, 2024 (the “first Addison Trial”).18
Relevant to the instant Motions in Limine, on December 28, 2015, Jefferson Parish
contracted with Aptim to provide operation and maintenance services (the “2015

Contract”) for the Landfill’s gas collection and control system (“GCCS”).19 Aptim operated
and maintained the GCCS from January 1, 2017 until May 17, 2019, under the 2015
Contract.20 Aptim engaged expert Barry Kline, P.E., represented to be an expert on landfill
gas collection and control,21 to “testify regarding the incomplete [GCCS] [Aptim] was
provided to operate,” as well as to Aptim’s duties and responsibilities under the 2015
Contract.22 Mr. Kline expressed nine opinions in his expert report (the “Kline Report”)
related to Aptim’s “performance as the operator” of the Landfill’s GCCS “to support the
opinion that Aptim performed competently and professionally at [the Landfill] relative to
the limitations place[d] on it.”23

22 Aptim’s Expert Witness List for the first Addison Trial identifies the scope of Mr. Kline’s testimony:
Considering that Aptim was a contractor hired to operate the [GCCS] as it existed at the []
Landfill, Mr. Kline will testify regarding the incomplete [GCCS] it was provided to operate,
that Aptim was not responsible for the receipt of waste materials, that Aptim was not
responsible for the design of the [GCCS], that Aptim had no control over the timing of the
installation of the [GCCS] components, that Aptim was faced with circumstances beyond
its control regarding [GCCS] operations and maintenance, that Aptim was limited in its
ability to operate and maintain the [GCCS] by its contract with Jefferson Parish, that Aptim
had no control over leachate levels in Phase IIIB or Phase IVA, that Aptim had no control
over the timing of installation of in-well pumps in Phase IVA landfill gas wells, that Aptim
had no control over the selection or installation of landfill cover materials and that
monitoring for onsite or offsite odors was outside of the scope of Aptim’s contract with
Jefferson Parish. R. Doc. 420 at pp. 3-4.
23 Kline Rep., R. Doc. 551-2 at pp. 5-6.
In February 2024, the Court issued the Thirteenth CMO, which required the
parties to file all motions in limine regarding expert testimony in the first Addison trial
by June 6, 2024.24 The Movants timely filed their Motions in Limine seeking to exclude
Mr. Kline’s Report and testimony under Federal Rules of Evidence 702 and 704.25
LEGAL STANDARD

I. Motion in Limine Standard
“It is well settled that motions in limine are disfavored.”26 “[T]he purpose of a
motion in limine is to prohibit opposing counsel ‘from mentioning the existence of,
alluding to, or offering evidence on matters so highly prejudicial to the moving party that
a timely motion to strike or an instruction by the court to the jury to disregard the
offending matter cannot overcome its prejudicial influence on the jurors’ mind.’”27
“Evidence is relevant” if “it has any tendency to make a fact . . . of consequence in
determining the action” “more or less probable than it would be without the evidence.”28
“Evidence which is not relevant is not admissible.”29 Under Federal Rule of Evidence 403,
the Court may exclude even relevant evidence “if its probative value is substantially
outweighed by a danger of . . . unfair prejudice.”30 “‘Unfair prejudice’ . . . means an undue

tendency to suggest decision on an improper basis, commonly, though not necessarily, an
emotional one.”31
“An order in limine excludes only clearly inadmissible evidence; therefore evidence

should not be excluded before trial unless it is clearly inadmissible on all potential
grounds.”32 Instead, courts should reserve evidentiary rulings until trial so that questions
as to the evidence “may be resolved in the proper context.”33 “When ruling on motions in
limine, the Court ‘maintains great discretion [as to] evidentiary determinations.’”34 If the
evidence is not clearly inadmissible on all grounds, it is better for the court to decline to

rule in advance of trial so that it will have the opportunity to resolve issues in context.
II. Federal Rule of Evidence 702 Standard
Rule 702 of the Federal Rules of Evidence governs the admissibility of expert
witness testimony:
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:
(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 has reliably
applied the principles and methods to the facts of the case.35
Testimony from a qualified expert is admissible only if it is both relevant and reliable.36
Thus, the threshold inquiry is whether the expert witness possesses the requisite
qualifications to render an opinion on particular subject matter.37
If the expert’s qualifications are found to be sufficient, the court must then examine
whether the expert’s opinions are reliable and relevant.38 The United States Supreme

F.3d 935, 937 (5th Cir. 1999) (“A district court should refuse to allow an expert to testify if it finds that the
witness is not qualified to testify in a particular field or a given subject.”).
38 United States v. Valencia, 600 F.3d 389, 424 (5th Cir. 2010).
Court’s decision in Daubert v. Merrell Dow Pharmaceuticals, Inc.,39 provides the
analytical framework for determining whether expert testimony is admissible under Rule
702. “Under Daubert, Rule 702 charges trial courts to act as ‘gate-keepers,’ making a
‘preliminary assessment of whether the reasoning or methodology underlying the
testimony is scientifically valid,’”40 and of whether that reasoning or methodology “can be

reliably applied to the facts of the case.”41 The party offering the expert opinion must show
by a preponderance of the evidence that the expert’s testimony is reliable and relevant.42
“[E]xpert testimony proffered” must be “sufficiently tied to the facts of the case
that it will aid the jury in resolving a factual dispute.”43 This is essentially a relevance
requirement—relevant evidence, including relevant expert testimony, is that which has
“any tendency to make the existence of any fact that is of consequence to the
determination of the action more probable or less probable than it would be without the
evidence.”44 With respect to the proper scope of expert testimony, Rule 704 provides that
“testimony in the form of an opinion or inference otherwise admissible is not
objectionable because it embraces an ultimate issue to be decided by the trier of fact.”45
Nevertheless, “[i]f the expert’s testimony brings no more to the finder of fact than the

lawyers can offer in argument, the expert’s opinions should be excluded.”46

“[A]n expert may never render conclusions of law,”47 as that “would constitute an
invasion of ‘the province of the court to determine the applicable law and to instruct the
jury as to that law.’”48 Allowing such expert testimony in a jury trial is both unhelpful and
harmful because
the jury would be very susceptible to adopting the expert's conclusion rather
making its own decision. There is a certain mystique about the word ‘expert’
and once the jury hears of the [expert]’s experience and expertise, it might
think the witness even more reliable than the judge. If an expert witness
were allowed to testify to legal questions, each party would find an expert
who would state the law in the light most favorable to its position. Such
differing opinions as to what the law is would only confuse the jury.49

Accordingly, expert testimony that offers a legal opinion is inadmissible.50 Moreover,
“expert testimony on matters which a jury is capable of understanding and deciding
without an expert’s help should be excluded,”51 because expert testimony is appropriate
only when it will assist the trier of fact.52
LAW AND ANALYSIS
Defendant Aptim offers Barry Kline, P.E., a principal remediation engineer, as its
“landfill gas collection and control expert.”53 According to his Report, Mr. Kline currently
operates or oversees the operation of landfill gas collection and treatment systems and
leachate pumping systems and has experience designing, operating, and maintaining

mechanical remediation systems.54 Aptim engaged Mr. Kline to evaluate its performance
as operator of the Landfill’s GCCS during the relevant time period.55 Mr. Kline ultimately
expressed nine opinions in his Report:
Opinion No 1: APTIM was only provided with a partially-installed GCCS to
operate in Phase IVA and the timing of its installation and expansion was
outside of APTIM’s control.

Opinion No. 2: APTIM was not responsible for the receipt of waste
materials, waste placement, waste processing, or waste solidification,
including the deposition or use of materials, such as spent lime or fly ash,
that may have led to the increased concentrations of hydrogen sulfide (H2S)
within the landfill gas being generated.

Opinion No. 3: APTIM did not have control over the design of the GCCS in
Phase IVA nor did APTIM have control over the timing of installation of
various GCCS components, such as gas extraction wells and collection
system piping. Additionally, APTIM could only operate the partially-
installed GCCS in the condition and configuration provided to it by
Jefferson Parish.

Opinion No. 4: APTIM did not have control over various limitations placed
on the GCCS operation by others, especially when circumstances beyond
APTIM’s control, such as limited vacuum and vacuum interruptions to the
wellfield, further impeded GCCS operation. Such restrictions limited
optimization of the GCCS operation and its ability to capture the landfill gas
being produced within the landfill by the breakdown of waste materials.

Opinion No. 5: APTIM’s work at JPLF was limited by Contract/Agreement
provisions and language to specific tasks. Additionally, the
Contract/Agreement further limited APTIM’s efforts by placing restrictions
on the amount of time/effort O&M personnel could spend working on the
GCCS, including being subject to Jefferson Parish’s approval for all non-
routine GCCS work and limits on spending relative to expenses necessary
for the Operation and Maintenance tasks.

Opinion No. 6: APTIM did not have control over the leachate levels in Phase
IVA that allegedly impaired the operation of the GCCS.

Opinion No. 7: APTIM did not have control over the timing of the purchase
and installation of the in-well leachate/condensate pumps in Phase IVA gas

55 Id.
wells, or in other phases. APTIM did operate and maintain pneumatic
pumps, once installed, in gas wells throughout the landfill.

Opinion No. 8: APTIM did not have control over the specification,
procurement, inspection, or placement of landfill cover materials. APTIM
was not contracted to maintain any cover materials in any of the Phases of
the landfill. APTIM only inspected landfill cover materials in conjunction
with performing NSPS-required Surface Emissions Monitoring on a
quarterly basis.

Opinion No. 9: Ambient and environmental monitoring for odors onsite and
offsite was outside the scope of APTIM’s contract with Jefferson Parish.
Instead, IESI/Waste Connections’ Agreement with Jefferson Parish
required it to monitor for and control odors.56

The Movants do not challenge Mr. Kline’s qualifications, the reliability of his
methods, or the relevance of his testimony.57 Instead, the Movants seek to exclude Mr.
Kline’s Report and testimony under Rules 702 and 704, insofar as it improperly includes
legal conclusions based on Mr. Kline’s interpretation of the 2015 Contract and embraces
factual issues to which “Aptim’s own employees could testify,” and which will not
otherwise assist the trier of fact.58
I. Mr. Kline may not offer legal conclusions on the scope of Aptim’s
contractual duties based on his interpretation of the 2015 Contract.

The Movants argue the Kline Report expresses inadmissible legal conclusions that
“attempt to negate fault on the part of Aptim . . . based on [Mr. Kline’s] interpretation of
[the 2015 Contract].”59 Specifically, the Movants claim Mr. Kline’s opinions that Aptim

“did not have control” or was “limited by [the 2015 Contract]” constitute legal conclusions
that attempt to instruct the jury how to apportion fault in this case.60 The Movants
contend Mr. Kline’s testimony is unnecessary because “the words of the contract are able
to be understood by the jurors, and further will be testified to by fact witnesses.”61 In
opposition, Aptim argues Opinion Nos. 1, 2, 3, 4, 6, 7, and 8 offer admissible “expert

analysis of the specific, underlying components of the operations at the [Landfill],” which
will assist the jury in determining the scope of Aptim’s contractual duty and whether
Aptim maintained operational control of the GCCS during the relevant time period.62
Aptim further argues that Opinion No. 5 is “an expert opinion on the effect of the subject
contract on Aptim’s ability to perform its scope of work” at the Landfill, which “‘shed[s]
light’ on contractual terms by citing to customs and usage in the industry.”63 Aptim
concedes that the second sentence of Opinion No. 9 “is an admissible legal conclusion”
and makes no argument as to the admissibility of the first sentence. 64
“Interpretation of a contract is the determination of the common intent of the
parties.”65 “When the words of a contract are clear and explicit and lead to no absurd
consequences, no further interpretation may be made in search of the parties’ intent.”66

“The words of a contract must be given their generally prevailing meaning. Words of art
and technical terms must be given their technical meaning when the contract involves a

technical matter.”67 “A provision susceptible of different meanings must be interpreted
with a meaning that renders it effective and not with one that renders it ineffective.”68 “A
doubtful provision must be interpreted in light of the contract, equity, usages, the conduct
of the parties before and after the formation of the contract, and of other contracts of a
like nature between the same parties.”69

Under Louisiana law, “[i]nterpretation of an unambiguous contract is a question
of law, while interpretation of an ambiguous contract is a question of fact.”70 “[A]n expert
may never render conclusions of law,”71 and accordingly, may not offer legal conclusions
based on the interpretation of an unambiguous contract.72 Expert testimony is
appropriate, however, when “a phrase in a contract is ambiguous and a court seeks to
determine ‘whether there is a received usage in the trade which would shed light on its
meaning.’”73 Courts in the Fifth Circuit often rely on “individuals experienced in a
particular field for the purposes of obtaining explanation of the technical meaning of
terms used in the industry.”74 Indeed, “[i]n construing a specific contractual term, [the
court] must give consideration to the meaning attributed to that term in the industry.”75
Thus, expert testimony may be admissible to “provide context on an industry practice and

interpret contractual provisions specific to such an industry,” at the district court’s

discretion, but only when the explanation will assist the jury in “more accurately
comprehend[ing] the meaning of technical terms used within that industry or trade.”76
For example, in Greenup Industries LLC v. Five S Group, LLC, a recent case arising
out of a construction contract dispute between a contractor and subcontractor, Judge
Eldon E. Fallon considered a motion to exclude the expert testimony of a civil and

environmental engineer, which the movant claimed included inadmissible expert
opinions that “sp[oke] to factual questions of contractual interpretation.”77 The relevant
opinions expressed by the expert in that case were: (1) that a subcontract at issue
incorporated the defendant’s bid proposal and that the defendant was entitled to standby
time compensation; and (2) that “the primary reason for low productivity and schedule
slippage was [the Plaintiff’s] inability to provide the required amount of trucks on a
consistent basis.”78 Acknowledging the expert was qualified to testify to issues that would
help the jury resolve factual questions in the civil and environmental engineering fields,
the Greenup court found the expert “stepped outside his area of expertise to opine on the
contractual responsibilities of the parties.”79 The court reasoned that, although expert
testimony “is appropriate when the expert can ‘shed light’ on contractual terms by citing

customs and usage in the industry,” the expert’s report did not “explain how industry
customs support any of his [opinions] regarding the contractual responsibilities of the
parties,” and ultimately the court precluded the engineer expert from offering “any legal
conclusions on the contractual responsibilities of the parties.”80

In this case, although Aptim contends the 2015 Contract contains “specialized
language,” neither party to the 2015 Contract suggests it is ambiguous and Aptim fails to
call attention to any particular term that warrants expert testimony to properly
contextualize.81 A review of the Kline Report reveals instead that each of Mr. Kline’s nine
opinions purports to interpret the scope of Aptim’s duty under the 2015 Contract.

Specifically, Opinion Nos. 1, 2, 3, 4, 6, 7, and 8 express Kline’s opinion that Aptim “did
not have control over” or “was not responsible for”: the timing of the installation and
expansion of the Landfill’s GCCS;82 the receipt of waste materials, waste placement, waste
processing, or waste solidification;83 the design of the GCCS in Phase IVA or the timing
of installation of various GCCS components;84 various limitations placed on the GCCS
operation by others;85 the leachate levels in Phase IVA;86 the timing of the purchase and
installation of the in-well leachate/condensate pumps in Phase IVA gas wells or in other
phases;87 and the specification, procurement, inspection, placement, or maintenance of
landfill cover materials in any phases of the Landfill.88 Further, Opinion Nos. 5, 8, and 9
explicitly express legal conclusions based on Mr. Kline’s interpretation of the 2015
Contract, including in relevant part: “Aptim’s work at [the Landfill] was limited by

Contract/Agreement provisions and language to specific tasks”;89 “Aptim was not
contracted to maintain any cover materials”;90 and “[a]mbient and environmental

monitoring for odors onsite and offsite was outside the scope of APTIM’s contract with
Jefferson Parish” and the 2015 Contract “required [Jefferson Parish] to monitor for and
control odors.”91
The Court finds the scope of Aptim’s duty under the 2015 Contract and whether
Aptim’s performance complied with the 2015 Contract are issues about which fact

witnesses will testify and lawyers will argue rather than matters suitable for expert
testimony. Accordingly, Mr. Kline’s testimony providing legal conclusions on the
contractual responsibilities of the parties to the 2015 Contract, including the scope of
Aptim’s duties and whether Aptim complied with its obligations, as expressed in Opinion
Nos. 2, 5, 6, and 9 and portions of Opinion Nos. 1, 3, 4, 7, and 8, will be excluded.92
II. Mr. Kline may not parrot the testimony of fact witnesses. Mr. Kline
will be allowed to offer the portion of Opinion No. 4, in which he
opines limited vacuum and vacuum interruptions to the wellfield
“impeded” or “limited optimization” of the GCCS operation.

As discussed, portions of Opinion Nos. 1, 3, 4, 7, and 8 will be excluded because
they are legal conclusions based on Mr. Kline’s interpretations of the 2015 Contract.

91 Id. at p. 7 (Opinion No. 9).
92 On these grounds, the Court excludes Opinion Nos. 2, 5, 6, and 9 in toto, and those certain portions of
Opinion Nos. 1, 3, 4, 7, and 8, as set out below:
Opinion No. 1: “[T]he timing of its installation and expansion was outside of APTIM’s
control.”
Opinion No. 3: “APTIM did not have control over the design of the GCCS in Phase IVA nor
did APTIM have control over the timing of installation of various GCCS
components, such as gas extraction wells and collection system piping.”
Opinion No. 4: “APTIM did not have control over various limitations placed on the GCCS
operation by others, especially when circumstances beyond APTIM’s
control . . . .”
Opinion No. 7: “APTIM did not have control over the timing of the purchase and
installation of the in-well leachate/condensate pumps in Phase IVA gas
wells, or in other phases.”
Opinion No. 8: “APTIM did not have control over the specification, procurement,
inspection, or placement of landfill cover materials. APTIM was not
contracted to maintain any cover materials in any of the Phases of the
landfill.”
See id. at pp. 6-7. The Court will analyze the admissibility of the remaining portions of Opinion Nos. 1, 3, 4,
7, and 8 in Part II.
However, “evidence should not be excluded before trial unless it is clearly inadmissible
on all potential grounds.”93 Accordingly, the Court will analyze the admissibility of the
remaining portions of those opinions.
The Movants argue portions of Opinion Nos. 1, 3, 4, 7, and 8 “implicate factual
issues to which Aptim’s own employees could testify,” and which are otherwise

inadmissible under Rule 702 because they do not “assist the trier of fact to understand
the evidence or to determine a fact in issue.”94 In opposition, Aptim concedes the Kline
Report “partially asserts [] factual conclusion[s] drawn from information in the
possession of lay witnesses,” but claims Mr. Kline’s testimony is admissible under Rule
703 to contextualize “the overly technical issues” of the case, which are “well outside the
understanding of a lay juror.”95 Aptim contends Mr. Kline’s opinions are “essential for the
jury to understand and appreciate the complex workings of [the GCCS]” and “will assist
the jury in determining Aptim’s fault.”96
A review of the Kline Report reveals the portions of Opinion Nos. 1, 3, 4, 7, and 8
that do not contain inadmissible legal conclusions merely parrot testimony by fact
witnesses.97 While “testimony in the form of an opinion or inference otherwise admissible

client’s version of the facts”).

97 Federal Rule of Evidence 1006 allows a proponent to “use a summary . . . to prove the content of
voluminous writings, recordings, or photographs that cannot be conveniently examined in court.” FED. R.

admission of summaries when (1) the evidence previously admitted is voluminous, and (2) review by the
jury would be inconvenient.”). The Fifth Circuit “expressly allows summary witnesses to summarize
voluminous records in complex cases” under Rule 1006. United States v. Baker, 923 F.3d 390, 397 (5th Cir.
2019) (citing United States v. Armstrong, 619 F.3d 380 (5th Cir. 2010). A summary witness is permitted to
“read[] the contents of exhibits and sort[] through the evidence to show how the documents relate[] to each
other,” but may not offer “expert-type testimony.” Baker, 923 F.3d at 398; United States v. Nicholson, 961

Rule 1006. He cannot merely summarize the testimony offered by fact witnesses.
is not objectionable because it embraces an ultimate issue to be decided by the trier of
fact,”98 “[e]xpert testimony that does nothing more than ‘mirror’ testimony offered by fact
witnesses should [] be excluded.”99 When determining whether an expert may opine on
technical issues, courts evaluate “the common sense inquiry whether the untrained
layman would be qualified to determine intelligently and to the best degree the particular

issue without enlightenment from those having a specialized understanding of the subject
involved in the dispute.”100
The Court finds the portions of Opinion Nos. 1, 3, 7, and 8 mirroring fact testimony
“embrace an ultimate issue to be decided by the trier of fact” that “the untrained layman
would be qualified to determine intelligently” without Mr. Kline’s testimony. 101 Those
opinions merely repeat certain fact testimony related to Aptim’s operation at the Landfill
during the relevant time period. Specifically, Opinion Nos. 1, 3, 7, and 8 express that
Aptim: “was only provided with a partially-installed GCCS to operate in Phase IVA”;102
“could only operate the partially-installed GCCS in the condition and configuration
provided to it by Jefferson Parish”;103 operated and maintained pneumatic pumps in gas
wells throughout the Landfill;104 and “inspected landfill cover materials in conjunction

with performing . . . Surface Emissions Monitoring on a quarterly basis,” as required by
federal regulation.105 These portions of Mr. Kline’s opinions do nothing more than mirror

testimony offered by Aptim’s fact witnesses and are “well within the common sense
understanding of jurors.”106 Accordingly, Mr. Kline’s testimony, as expressed in the
remainder of Opinion Nos. 1, 3, 7, and 8, will be excluded.
While the portion of Opinion No. 4 expressing the fact that limited vacuum and
vacuum interruptions to the wellfield impeded the GCCS operation “embrace[s] an

ultimate issue to be decided by the trier of fact,” the Court finds the opinion implicates
issues that are beyond “the common sense” and general knowledge of an “untrained
layman.”107 In relevant part, Opinion No. 4 states that certain “circumstances beyond
APTIM’s control, such as limited vacuum and vacuum interruptions to the wellfield, []
impeded GCCS operation[,] [and] [s]uch restrictions limited optimization of the GCCS
operation and its ability to capture the landfill gas being produced within the landfill by
the breakdown of waste materials.”108 The opinion expressed in Opinion No. 4 is unlike
those expressed in Opinion Nos. 1, 3, 7, and 8, as the jury may have difficulty “adeptly
assess[ing] [the] situation using only their common experience and knowledge.”109 The
Court finds that Mr. Kline’s “specialized understanding of the subject [matter]”110
underlying Opinion No. 4 is likely to “help the trier of fact to understand the evidence or

determine a fact in issue.”111
As discussed, Mr. Kline may not testify as to the legal conclusion that certain
“circumstances [were] beyond APTIM’s control.”112 However, the Court will allow Mr.
Kline to offer limited testimony related to Opinion No. 4—that limited vacuum and

IT IS ORDERED that Plaintiffs’ Motion in Limine is GRANTED IN PART
AND DENIED IN PART as stated herein.144
IT IS FURTHER ORDERED that Jefferson Parish’s Motion in Limine is
GRANTED IN PART AND DENIED IN PART.115
Mr. Kline may not offer testimony on Opinion Nos. 1, 2, 3, 4, 5, 6, 7, 8, and 9, which
express legal conclusions on the scope of Aptim’s contractual duties based on his
interpretation of the 2015 contract and/or merely parrot facts that will be testified to by
fact witnesses. Mr. Kline may offer limited testimony related to Opinion No. 4, insofar as
he expresses his opinion that limited vacuum and vacuum interruptions to the wellfield
impeded or limited optimization of the GCCS operation.
