SUMMARY

Regular Appropriations Acts: Selected
Statutory Interpretation Issues
The Constitution’s Appropriations Clause provides that “No Money shall be drawn from the
Treasury, but in Consequence of Appropriations made by Law.” Congress, and not another
branch of government, therefore decides whether and on what terms to fund government
programs. When it does, Congress provides appropriations or other budget authority. This
statutory authority is essential to carry out nearly all government programs.

As a legal matter, Congress can include an appropriation or other budget authority in any bill or joint resolution; as a
procedural matter, Congress has chosen to supply funding for many of the continued operations of federal departments,
agencies, and programs through a type of bill referred to as a regular appropriations bill. Under current committee structures,
Congress may separately enact up to 12 regular appropriations bills for a given fiscal year, though more and more, Congress
enacts one or more regular appropriations bills together in a statute sometimes referred to as a consolidated or omnibus
appropriations act.
Regular appropriations acts stand apart from other statutes in content, structure, and context. Since 1789, regular
appropriations acts have been drafted “for the service” (i.e., for the use of) a single fiscal year; much of the legal authority
such acts provide comes with its own expiration date. When Congress enacts regular appropriations acts, its primary focus is
the granting of appropriations and other budget authority, and procedural rules discourage the inclusion of “legislation” in
such acts. Modern-day regular appropriations acts—those enacted for Fiscal Year (FY) 2000 and thereafter—employ a
legislative format that differs in key respects from that of other statutes enacted during the same time period. Congress’s
consideration of regular appropriations acts also generates detailed committee and other legislative reports, such as
explanatory statements, which Congress might use to further control or influence, in varying ways, use of appropriated funds.
Because modern-day regular appropriations acts employ structure and include matter that does not appear in other
contemporary statutes, these appropriating acts raise questions for agencies that other statutes typically do not. For example,
the fact that most of the appropriations contain an expiration date requires agencies to ensure that particular expenses are
properly incurred using time-limited funds. Agencies may also have to consider the effect that the various reports that
accompany regular appropriations acts have on their authority to use appropriated funds, potentially implicating the
constitutional doctrine of bicameralism and presentment and the statutory doctrine of incorporation by reference.
Not only do modern-day regular appropriations acts pose unique questions, courts often read such acts through lenses that are
not applied to other statutes. That is because, over time, courts have arrived at a particular understanding of Congress’s
appropriating function, influenced by such factors as the perceived nature of appropriations acts and the effect of chamber
rules that govern consideration of general appropriations bills. Given this understanding, courts have crafted presumptions
concerning regular appropriations act provisions to yield conclusions about statutory meaning that appear to most faithfully
reflect legislative intent. Thus, when Congress writes the unnumbered paragraphs of an appropriations act using a principal
clause/proviso format, as it has for centuries, courts will usually read the proviso as being confined to the subject matter of its
principal clause; the proviso will not be read to introduce new matter that is not connected to the principal clause. Courts will
also presume that matter in a regular appropriations act does not modify preexisting substantive law that fixes rights, duties,
and obligations. Even when an act overcomes this presumption, courts will further presume that the act in question only
modifies substantive law for the fiscal year. By understanding these and other presumptions, Congress can tailor the language
of appropriations acts to ensure that courts interpret that language as intended.

Regular Appropriations Acts: Selected Statutory Interpretation Issues

regular appropriations act is a statute that provides funding for the continued operation
of federal departments, agencies, and government activities for a particular fiscal year.1
The legal meaning of a regular appropriations act is generally determined by applying the
same rules that govern the interpretation of other statutes.2 Just as with statutes that authorize
government programs or otherwise regulate public or private conduct,3 courts4 and agencies5
usually interpret the undefined words and phrases of an appropriations act by looking to their
ordinary meaning. Ordinary meaning is usually found in dictionary definitions.6 Like other
statutes,7 words and phrases in an appropriations act are interpreted in context of the act in which
they appear.8 Other canons of construction apply just as much to appropriations acts as to other
statutes.9 When construing statutory text, including provisions in appropriations acts,10 a court
might also look to a statute’s legislative history. This record of Congress’s consideration of and

commentary on the bill that became law might be used to confirm the meaning that is otherwise
evident in the statutory text itself,11 or it might be used to clarify the meaning of an ambiguous
statute.12 Regardless of the type of statute at issue, whether appropriating or not, the ultimate goal
of statutory interpretation is to determine congressional intent.13
However, regular appropriations acts also differ from other statutes in important respects, in form
but more importantly in substance. Regular appropriations acts look different from most other
federal statutes, using what commentators have called a “maverick style” of organization.14 Their
chief function is the granting of appropriations, a constitutionally unique legal authority that is
necessary for an agency to draw funds from the Treasury to pay the government’s debts.15
Reinforcing this focus on funding government programs, chamber rules discourage Members of
Congress from including “legislation” in a regular appropriations act, creating, at least as a
procedural matter, a “separation between policy and money decisions.”16 As a rule, the primary
legal authority provided in a regular appropriations act is qualified in its duration—most of its
appropriations have an expiration date. Regular appropriations acts are also accompanied by
detailed committee reports. Sometimes on their own and sometimes in conjunction with
references in the statute to the committee or other legislative reports, these reports state that the
funds within an appropriation should be allocated in a certain way, issue directives to agencies, or
otherwise exercise oversight over the agencies and programs that the act funds.
These differences in the form and function of regular appropriations acts and the context in which
Congress considers appropriations acts affect the types of interpretive questions that such acts
raise. Moreover, because courts perceive differences between regular appropriations and other
statutes, courts may conclude that on certain questions, congressional intent is most accurately
gauged using rules of interpretation tailored to appropriations acts. After discussing the typical
format of a regular appropriations act, this report examines frequently recurring questions of
statutory interpretation raised by such acts. This report compiles the terms it defines in a glossary

court” from possessing a firearm as applying only to domestic convictions and stating that statute’s “lengthy legislative
history confirms” that foreign convictions would not trigger the firearms disability).

Regular Appropriations Acts: Selected Statutory Interpretation Issues

Anatomy of a Statute Making Regular
Appropriations
This report addresses a type of statute referred to as a regular appropriations act, which is only
one of a number of appropriations acts that Congress might enact in a given year. A regular
appropriations act provides funding for the continued operation of federal departments, agencies,
and government activities for a particular fiscal year.17 As used in this report, the term excludes
appropriations acts that make only continuing, deficiency, or supplemental appropriations.18 It
also does not describe those laws, other than appropriations acts, that provide budget authority.19
Budget authority is statutory authority to incur financial obligations on behalf of the United States
that will result in an outlay of federal funds.20 Usually, this authority takes the form of an
appropriation, which is statutory authority to both obligate the government and make payments
out of the Treasury.21 After enactment of such funding authority, the Department of the Treasury
(Department) issues appropriation warrants, which are “evidence of Congressional action to fund
programs” and establish the money that an “entity is authorized to withdraw from the General
Fund of the U.S. Government.”22 The Department establishes appropriations accounts
corresponding to each appropriation.23 Agencies use accounts to reflect their use of
appropriations.
Under the current structure of the House and Senate Appropriations Committees, there are 12
regular appropriations acts, each drafted annually by a subcommittee with jurisdiction over
specified agencies and programs.24 While the Appropriations Committees might typically first
draft and mark up the different regular appropriations bills as stand-alone measures, Congress
increasingly enacts the regular appropriations bill into law by combining one or more into a
measure that is designated as, variously, a “consolidated” or “omnibus” appropriations act.25
Modern-day statutes making regular appropriations26 typically include up to four basic
components: prefatory matter, so-called “preceding matter,” unnumbered paragraphs, and general

provisions. Moreover, while the text of committee and other legislative reports that are drafted to
accompany regular appropriations acts do not appear within the four corners of the act, such
reports are important products of the legislative process.

Prefatory Matter
A statute making regular appropriations begins with statutorily prescribed prefatory matter. First,
the act’s title will indicate the fiscal year and, in general terms, the objects for which the act
makes appropriations.27 Second, the measure will contain an enacting clause if it is styled as an
act28 or a resolving clause if it is styled as a joint resolution.29

Preceding Matter
The next component of a statute making regular appropriations is a collection of what in recent
fiscal years30 has been styled as numbered sections that precede the portions of the act that make
particular appropriations (“preceding matter”).31 When they appear, preceding matter provisions
tend to appear in the same form from year to year,32 but whether a statute making regular
appropriations includes a particular preceding matter provision depends on the content of the act,
appropriations for Fiscal Year (FY) 2000 and thereafter. Thus, this report’s use of the modifier “modern-day” should be
understood to refer to the time period FY2000 through FY2021.
27 See 1 U.S.C. § 105 (“The style and title of all Acts making appropriations for the support of Government shall be as
follows: ‘An Act making appropriations (here insert the object) for the year ending September 30 (here insert the
calendar year).’”). Beginning with FY1977, appropriations acts have made appropriations for fiscal years ending
September 30. Previously, a fiscal year ended on June 30 of a calendar year. See Congressional Budget Act of 1974,
Pub. L. No. 93-344, § 506(a)–(b), 88 Stat. 297, 322 (1974). The style and title of acts making appropriations for
FY1975 and prior fiscal years therefore track this earlier fiscal-year calendar. See, e.g., Foreign Assistance and Related
Programs Appropriations Act, 1972, Pub. L. No. 92-242, 86 Stat. 48, 48 (1972) (“Making appropriations for Foreign
Assistance and related programs for the fiscal year ending June 30, 1972, and for other purposes.”). Acts making
appropriations for FY1976 included funding for an additional three-month period, after June 30, 1976, to enable
transition to the new fiscal year calendar. See, e.g., Department of Transportation and Related Agencies Appropriation
Act, 1976, Pub. L. No. 94-134, 89 Stat. 695, 695 (1975) (“Making appropriations for the Department of Transportation
and related agencies for the fiscal year ending June 30, 1976, and the period ending September 30,1976, and for other
purposes”).
28 See 1 U.S.C. § 101; see also Killion, Understanding Federal Legislation, supra note 2, at 19.
29 See 1 U.S.C. § 102; see also Consolidated Appropriations Act, 2019, Pub. L. No. 116-6, 133 Stat. 13, 13 (2019)
(joint resolution); CONSTITUTION, JEFFERSON’S MANUAL, AND RULES OF THE HOUSE OF REPRESENTATIVES OF THE
UNITED STATES ONE HUNDRED SIXTEENTH CONGRESS, H.DOC. NO. 116-177, § 397 (2021) [hereinafter RULES OF THE
HOUSE] (A joint resolution “is a bill so far as the processes of the Congress in relation to it are concerned,” and, except
for a joint resolution proposing a constitutional amendment, “are sent to the President for approval and have the full
force of law” when enacted. “They are used for what may be called the incidental, unusual, or inferior purposes of
legislating,” including the making of certain appropriations).
30 The use of numbered sections to delineate preceding matter is more common in more recent statutes making regular
appropriations, in particular those pertaining to FY2008 or thereafter. Before then usually only a statement of
appropriations followed the act’s prefatory matter and preceded its appropriating provisions. Preceding matter is the
product of more complex appropriations act structure, and in particular Congress’s use of a consolidated or omnibus
measure to enact two or more regular appropriations acts.
31 See, e.g., Further Consolidated Appropriations Act, 2020, Pub. L. No. 116-94, Div. A., tit. II, § 222(a), 133 Stat.
2534, 2582 (2019) (referring to “the matter preceding division A of this consolidated Act” in directing certain transfers
(emphasis added)).
32 But see Consolidated and Further Continuing Appropriations Act, 2015, Pub. L. No. 113-235, §§ 9–11, 128 Stat.
2130, 2133–35 (2014) (preceding matter provisions appropriating funds, amending provisions of law relating to the
Northern Marianas Islands, and directing a study of electric rates in insular areas).

its method of enactment, and whether the act combines two or more regular appropriations bills. 33
Typical preceding matter include:


In measures that consolidate several appropriations bills, a provision regarding
the meaning of the phrase “this Act.”34
A statement of appropriations, reciting that sums in the Act are appropriated for a
designated fiscal year out of any money in the Treasury not otherwise
appropriated.35
A provision regarding the availability or rescission of funds designated by
Congress for Overseas Contingency Operations36 or as an emergency
requirement.37
A provision reciting that the explanatory statement printed by the Chair of the
House Committee on Appropriations, or another designee, on a specified date,
shall have the same effect for funds allocation and act implementation “as if it
were a joint explanatory statement of a committee of conference.”38

Unnumbered Paragraphs
Following any preceding matter are the regular appropriations acts themselves, which begin with
unnumbered paragraphs. These paragraphs are the primary provisions of the act that provide an
agency with the budget authority that allows federal officers and employees to incur financial
obligations on behalf of the United States that will result in an outlay of federal funds.39
The unnumbered paragraphs of a given regular appropriations act will typically be organized by
title, each reflecting, in the case of executive branch agencies, funding for a given agency40 or
related functions of an agency.41 If a statute making regular appropriations enacts two or more

Regular Appropriations Acts: Selected Statutory Interpretation Issues

regular appropriations acts together,42 the practice is that the measure will be drafted so that each
such act will appear in the statute in its own division.43
Appropriations are said to be made “under” a heading.44 A heading is a phrase in the
appropriations act that immediately precedes an unnumbered paragraph. The heading names the
appropriation or other authority contained in the paragraph.45 The heading may also include one
of a handful of frequently recurring parenthetical statements, some required by chamber rules,46
which serve to highlight that the text of the unnumbered paragraph contains particular types of
legal authorities.47
One of the most frequently recurring of these parenthetical heading statements reads “Including
Transfer of Funds.”48 A transfer shifts budget authority in one appropriation or fund account to
another.49 An agency needs statutory authority to transfer budget authority.50 Statutory authority to
make a transfer is called transfer authority.51 Thus, this parenthetical heading statement usually
denotes that the unnumbered paragraph includes transfer authority, permitting agencies to make
discretionary transfers, subject to the terms of the transfer authority.52 Occasionally, though, the

47 The parenthetical heading statements serve to highlight the presence of authority in the unnumbered paragraph itself
but are not necessary, as a legal matter, for the paragraph to provide a particular type of authority or limitation. For
example, Congress has written an unnumbered paragraph to function as a “limitation on obligations,” even though the
paragraph’s heading did not reference a limitation. Compare Consolidated Appropriations Act, 2004, Pub. L. No. 108199, Div. F, tit. I, 118 Stat. 3, 313 (2004) (Emergency Preparedness Grants) (imposing a limitation on amounts that
could be made available in FY2004 for obligation from a permanent appropriation but lacking any reference in the
paragraph’s heading to a limitation on obligations), with Consolidated Appropriations Act, 2021, Pub. L. No. 116-260,
Div. L, tit. I (2020) (Emergency Preparedness Grants) (imposing a similar limitation on amounts that could be made
available for obligation in FY2021 from the same permanent appropriation and including a heading reference to
“limitation on obligations”).

parenthetical heading statement might signal that in enacting the statute, Congress, itself, has
directed that a transfer be made, in which case the transfer is not discretionary.53
Another common parenthetical heading statement is “Including Rescission of Funds.”54 A
rescission cancels the availability of existing, unexpired budget authority that was provided in a
prior statute.55 Thus, this parenthetical heading statement indicates that in addition to providing
new budget authority, the unnumbered paragraph following the heading rescinds all or part of the
unobligated balance of budget authority that was provided in a prior statute.56
For each fiscal year Congress enacts unnumbered paragraphs that are preceded by a parenthetical
heading statement that reads “Liquidation of Contract Authorization.”57 Congress uses this
parenthetical heading statement to flag an unnumbered paragraph that discharges obligations
entered into using a type of budget authority called contract authority.58 Contract authority only
permits the making of a promise to pay in advance of appropriations.59 Such unnumbered
paragraphs provide liquidating appropriations, which are made only to pay the obligations
already incurred using contract authority.60
In addition, certain unnumbered paragraphs appear under headings that include the parenthetical
phrase “Limitation on Obligations.” Such unnumbered paragraphs limit the amount or type of
obligations that an agency may incur under budget authority provided in another statute, such as
in a permanent appropriation61 or through contract authority provided in an authorizing statute.62

Regular Appropriations Acts: Selected Statutory Interpretation Issues

The unnumbered paragraph follows the heading. As noted above, the chief function of the
paragraph is to provide budget authority. Congress usually defines the authority provided by a
particular grant of budget authority by defining its “availability” along three dimensions: an
amount of budget authority, the object or objects for which that budget authority is provided, and
the time period for which the recipient agency may obligate the budget authority.
Congress might write single-sentence paragraphs.63 Perhaps more commonly, Congress writes
unnumbered paragraphs to follow a principal clause/proviso structure. In this form, the paragraph
begins with a principal clause setting forth an amount of budget authority that the paragraph
makes available.64 Set off from the principal clause by means of a colon are one or more provisos,
which are clauses that begin with the italicized word “Provided.” The first proviso following a
principal clause will begin “Provided, that.” Any subsequent provisos relating to the same
principal clause will begin “Provided further, that.” A proviso usually states conditions that apply
to the allocation65 or obligation66 of the budget authority provided in the paragraph’s principal
clause.67

General Provisions
Following the unnumbered paragraphs that provide budget authority are general provisions.68
They often appear as numbered sections. Relevant general provisions might appear in the same
title69 as the unnumbered paragraphs to which they relate or in separate titles of the same regular
appropriations act.70 Recent Financial Services and General Government appropriations acts
contain general provisions that, by their terms, apply “government-wide.”71 It is possible for
63 See, e.g., Consolidated and Further Continuing Appropriations Act, 2015, Pub. L. No. 113-235, Div. A., tit. I, 128

Stat. 2130, 2144 (2014) (State Mediation Grants) (“For grants pursuant to section 502(b) of the Agricultural Credit Act
of 1987, as amended (7 U.S.C. 5101–5106), $3,404,000.”).

Office of Inspector General in carrying out the provisions of the Inspector General Act of 1978, $12,071,000, to remain
available until September 30, 2016 . . . .”). The principal clause may itself allocate part of the aggregate sum to one of
the several purposes for which the appropriation is available. See, e.g., Consolidated Appropriations Act, 2016, Pub. L.
No. 114-113, Div. A, tit. I, 129 Stat. 2242, 2246 (2015) (providing roughly $44 million for the Department of
Agriculture’s Office of the Chief Information Officer “of which not less than” $28 million “is for cybersecurity
requirements of the Department”).

general provisions that Congress last enacted in a prior fiscal year’s appropriations act to continue
to affect an agency’s statutory authorities in the current fiscal year, including its authority to
obligate new budget authority.72
General provisions serve a range of functions. As in unnumbered paragraphs,73 general provisions
may grant transfer authority74 or rescind existing budget authority.75 As in unnumbered
paragraphs, if general provisions include transfer authority or rescissions, the act will typically
indicate the existence of such authority using a parenthetical statement that appears either at the
beginning of the general provisions or before the general provision to which the parenthetical
statement relates.76 General provisions may impose limitations on the use of budget authority
provided in the act.77 General provisions may also impose new duties on an agency or provide the
agency new authorities.78 A general provision might, itself, appropriate funds.79 General
provisions may even express in precatory terms the sense of Congress on a particular subject.80

Legislative Reports
The discussion above highlights the four basic components of modern-day statutes making
regular appropriations—the provisions of an appropriations bill that become law after being
passed in identical form by both houses, presented to the President, and either approved by the
President or enacted into law over the President’s disapproval.81 The regular appropriations
process also yields legislative reports drafted to accompany the regular appropriations bills.
Unlike the bills they accompany, the reports are not subject to bicameral passage and
presentment, and thus do not generally have legal effect unless an appropriations act contain
legally sufficient terms of incorporation for report material.82

Regular Appropriations Acts: Selected Statutory Interpretation Issues

Over the course of its congressional consideration, a regular appropriations bill may be
accompanied by several reports. These reports may include a report drafted by the relevant
subcommittee of the House Committee on Appropriations to accompany the appropriations bill
drafted by that subcommittee; a report drafted by the relevant subcommittee of the Senate
Committee on Appropriations to accompany the bill that it considers; and, last of all, a report
styled as either a joint explanatory statement or as an explanatory statement.83 In their
appearance, a joint explanatory statement or explanatory statement may be similar to a committee
report.84 Whether a regular appropriations act is accompanied by a joint explanatory statement, an
explanatory statement, or no statement at all, depends on the procedure Congress used to enact
the relevant appropriations statute.
A joint explanatory statement is a formal product of a conference committee, which is one
method of resolving differences between the House- and Senate-passed versions of a bill. A
conference committee drafts a conference report, which “contains only formal statements of
whatever procedural actions the conferees propose that one or both houses take and the formal
legislative language the conferees propose that the two houses approve.”85 A conference
committee also drafts a joint explanatory statement to accompany the conference report. The joint
explanatory statement details the effect that the amendments or propositions of the conference
report will have on bill to which they relate.86
An explanatory statement is an informal product of action by Congress to resolve differences
between the House- and Senate-passed versions of legislation using an exchange of amendments
between the Houses rather than a conference committee. One or more bill managers involved in
negotiating the proposed amendment typically drafts the explanatory statement. 87
Reports that accompany appropriations acts can serve several functions. Even when the reports do
not impose legally binding requirements on the use of budget authority, the reports can, as a
practical matter, influence an agency’s use of its authorities.88 The reports may summarize the
provisions of the act. The reports may also contain detailed directives for the agencies funded in
the act, primarily (though not necessarily) related to program implementation. One common set
of directives reflects expectations of how an agency will allocate the funds of a given
appropriation among the various programs, projects, or activities that the appropriation funds. 89
83 See generally McNellis, Appropriations Report Language, supra note 46.
84 See, e.g., Roeder v. Islamic Republic of Iran, 333 F.3d 228, 236 (D.C. Cir. 2003) (noting that a joint explanatory

statement of a conference committee takes “the form of a committee report”). As for an explanatory statement, a bill
manager will enter the text of the statement in the Congressional Record before the bill’s enactment. See, e.g., 163
Cong. Rec. H3327 (daily ed. May 3, 2017) (joint explanatory statement accompanying H.R. 244, the Consolidated
Appropriations Act, 2017). After enactment, the House Appropriations Committee may prepare a committee print of
the regular appropriations act or acts, together with any explanatory statement, at which point the explanatory
statement’s formatting more closely resembles a committee report. See H. COMM. ON APPROPRIATIONS, 1

Regular Appropriations Acts: Selected Statutory Interpretation Issues

Regular appropriations acts commonly refer to their accompanying reports. A regular
appropriations act might, for example, state that an appropriation “shall be made available in the
amounts specifically designated in the respective tables included in the explanatory statement”
referenced in the act’s preceding matter.90

Selected Statutory Interpretation Questions
Both in their drafting and in their implementation, regular appropriations acts raise a number of
recurring questions of statutory interpretation. What does it mean for budget authority to be
available for a particular time period? Might a provision proposed for inclusion in a regular
appropriations act be construed as permanent or, alternatively, only effective for the fiscal year to
which the act relates? A discussion of these and other frequently recurring questions follows.

The Relationship Between Principal Clause and Proviso
Usually, a statute’s provisions will be divided between two or more sections. Sections are the
basic unit of organization for most federal statutes. Congress “ordinarily adheres to a hierarchical
scheme in dividing statutory sections.”91 In this hierarchy appear units of text denoted, in
descending order, as subsections, paragraphs, subparagraphs, clauses, subclauses, items, and
subitems, among others.92 Congress uses this structure, among other things, to express the
relationship between different parts of a section. For example, Congress might set forth the
section’s general rule in an initial subsection, and then establish related points in paragraphs
subordinate to that subsection.93
By contrast, the unnumbered paragraphs of a regular appropriations act, which could be
characterized as the basic unit of organization for appropriations acts, usually have no internal
hierarchy of sections, subsections, and so on.94 Instead, within unnumbered paragraphs Congress
uses a principal clause/proviso structure. Congress once used this structure more widely95 but
now generally reserves it for regular and supplemental appropriations acts.96 The principal clause

will grant an agency budget authority (i.e., legal authority to incur obligations). One or more
provisos then typically follow the principal clause.97
As a matter of ordinary meaning, and read in isolation, the term that separates the principal clause
from its provisos, “provided,” might plausibly bear more than one meaning.98 “Provided” might
mean “except” that or “[o]n the condition that.”99 The proviso might therefore create an exception
to, or impose a condition on, the budget authority provided in its principal clause. “Provided”
might also stand in the place of the conjunction “and.”100 If “provided” is used as a conjunction,
the proviso might not necessarily be confined to the budget authority provided in the principal
clause. Such a proviso might stand, instead, as independent matter whose breadth does not
depend on the principal clause.101
At least since 1841,102 Supreme Court case law has helped distinguish between these two
potential meanings by establishing a presumptive relationship between the principal clause and a
proviso that follows it: the scope of the proviso is confined to the subject matter of the principal
clause only, and either creates an exception to, or otherwise restrains, the authority provided in
the principal clause.103
United States v. Morrow104 illustrates the effect this presumption can have on budget authority.
There, Congress appropriated amounts for military clerks in two appropriations. In one
appropriation, Congress provided line-item amounts for clerks at the territorial departments’
headquarters, as well as an amount for additional pay for those in foreign service.105 A proviso
followed the line-item appropriation, directing a $200 increase in the annual salary of certain
clerks, including those in the headquarters of a territorial department, while serving in the
Philippine Islands.106 In the second appropriation, Congress provided a lump-sum amount for the
the term “provided” as “archaic”). Continuing appropriations acts typically do not include unnumbered paragraphs but
rather appropriate sums by referencing the rate for operations provided in a particular regular appropriations act or bill.
See, e.g., Continuing Appropriations Act, 2021 and Other Extensions Act, Pub. L. No. 116-159, Div. A, § 101, 134
Stat. 709, 710 (2020).

incidental expenses of the Quartermaster Corps.107 Morrow was the chief clerk of the depot
quartermaster’s office at the Philippine Department of the Army headquarters, and his regular
salary was paid from the second appropriation (i.e., the lump-sum appropriation).108 Morrow
argued he fell within the terms of the first appropriation’s proviso (i.e., the line-item
appropriation) and was thus entitled to the $200 increase109—he was a “clerk[],” serving abroad
in the “Philippine Islands,” in the “headquarters” of a “territorial department.”110
The Court rejected Morrow’s claim.111 The general function of a proviso, the Court explained, “is
to except something from” the principal clause “or to qualify and restrain its generality and
prevent misinterpretation.”112 Thus, the proviso’s “grammatical and logical scope is confined to
the subject-matter of the principal clause,” and presumptively “refers only to the provision to
which it is attached.”113 Reading the proviso as confined to its principal clause, the $200 increase
applied only to those clerks whose annual salaries were supported by the line-item appropriation,
excluding those clerks, such as Morrow, whose salaries were paid out of the lump-sum
appropriation.114 The $200 increase did not apply, more broadly, to any clerk who might fall
within the scope of the proviso, as it might if it had been enacted as a free-standing provision not
linked to the line-item appropriation’s principal clause.115
As noted above, the presumption that a proviso is confined to the subject matter of its principal
clause is only that: a presumption.116 The text and structure of a statute might overcome the
presumption, so that a court would read a proviso in an appropriations act as introducing “new
matter extending rather than limiting or explaining that which has gone before.”117
Republic of Iraq v. Beaty118 demonstrates how a proviso overcomes the presumption concerning
its connection to its principal clause. There, the Republic of Iraq argued that a 2003 supplemental
appropriations act119 enacted after the 2003 invasion of Iraq led to the removal of many of the
consequences of the country’s 1990 designation as a state sponsor of terrorism.120 Among other
things, the 1990 designation caused Iraq to lose its immunity from suit when, in 1996, Congress
added a terrorism exception to the Foreign Sovereign Immunities Act (FSIA).121 With immunity

Regular Appropriations Acts: Selected Statutory Interpretation Issues

allegedly restored as a result of the 2003 appropriations act, Iraq sought dismissal of claims
related to prisoner abuse that occurred during or after the Persian Gulf War.122
Iraq’s argument relied upon a general provision of the 2003 appropriations act that used a
principal clause/proviso structure.123 The principal clause permitted the President to suspend trade
and economic sanctions imposed under “any provision” of the Iraq Sanctions Act of 1990
(ISA).124 One of several provisos allowed the President to make inapplicable to Iraq a Foreign
Assistance Act prohibition on providing aid to a state sponsor of terrorism.125 The proviso also
allowed the President to make inapplicable to Iraq “any other provision of law that applies to
countries that have supported terrorism.”126 President George W. Bush exercised all of these
waiver authorities via a presidential memorandum.127
Applying the presumption in Morrow, the court of appeals read the disputed, any-other-provisionof-law proviso in the context of its principal clause.128 The principal clause and the disputed
proviso itself specifically referenced only statutes that imposed “obstacles to assistance to
designated countries.”129 The court of appeals reasoned that “[n]one of these provisions remotely
suggests any relation” to a statute like the FSIA that dealt with “the jurisdiction of the federal
courts.”130 Thus, the disputed proviso’s more general reference to “any other provision of law”
included only those provisions that, like the principal clause, restricted “assistance and funding
for the new Iraqi Government.”131 The any-other-provision-of-law language did not include a
statute, such as the FSIA, that related to the jurisdiction of federal courts.132
The Supreme Court disagreed.133 The Court explained, in keeping with Morrow, that a proviso
usually creates an exception to a principal clause or qualifies, restrains, or explains that clause.134
However, the Beaty Court noted that a proviso may introduce “independent legislation” whose
scope is not confined to its principal clause.135 The Court stated that this second usage “may be
lazy drafting” in view of the presumptive function of a proviso, but the second usage nonetheless

applied to the disputed proviso.136 Thus, the Court read the principal clause to grant “the President
a power; the [disputed] proviso purported to grant him an additional power.”137 The proviso “was
not, on any fair reading, an exception to, qualification of, or restraint on the principal power.”138
The Court supported this reading by contrasting the disputed proviso with other provisos to the
same principal clause, the latter of which included language that “plainly sought to define and
limit the authority granted” in the principal clause.139 No such language appeared in the disputed
proviso.140 Thus, FSIA’s terrorism exception was a “provision of law” that applied to “countries
that have supported terrorism.”141 The President’s memorandum made the terrorism exception
inapplicable to Iraq,142 even if Congress did not have the terrorism exception in mind when it
drafted the disputed proviso.143
Deciding whether a proviso is either confined to the scope of its principal clause (the presumptive
rule) or instead contains independent matter (the exception) depends on the text and structure of
the appropriations act text at issue. One indication that the presumptive rule applies may be, as in
Morrow, that the principal clause grants budget authority rather than, as in Beaty, new substantive
authority.144 On the other hand, the exception might apply if, as in Beaty, the proviso’s use of
broad language, not expressly tied to the authority of the principal clause, appears alongside other
provisos that are so expressly tied to the principal clause.145

Duration of Budget Authority
A critical component of the budget authority provided in a regular appropriations act is its
duration. This characteristic of budget authority describes the time period within which budget
authority is available for obligation.146 It is a key attribute of an agency’s obligational authority. If
Congress limits the duration of particular funding authority, the agency must return to Congress
when the funding lapses “to justify continuing the program or to debate about how much is
needed to carry on the program at the same or a different level.”147
Perhaps most commonly,148 the duration of budget authority is of a “definite” or “fixed” period.149
The appropriation will remain available for obligation until the end of the fiscal year for which

the act makes appropriations (i.e., one-year funds), or the appropriation will remain available for
obligation for more than one fiscal year (i.e., multi-year funds).150 Alternatively, duration may be
“indefinite.”151 Such an appropriation will remain available until it is expended (i.e., no-year
funds).
Regular appropriations may pose two primary questions concerning the duration of budget
authority. One such question arises when the appropriation itself omits express reference to its
duration. The second such question, and the more important of the two given the frequency with
which it affects agency decisionmaking, is what effect duration has on an agency’s ability to use a
particular amount of funds to meet its expenses.

Determining Duration
In most cases, the portions of a regular appropriations act that provide budget authority will
expressly state the duration of that budget authority. That is, the unnumbered paragraph will state
not only the amount of the appropriation and the objects for which it is available, but also the
time period within which the appropriation is available for obligation: “For necessary expenses of
the Management Directorate [of the Department of Homeland Security] for research and
development, $2,545,000, to remain available until September 30, 2020.”152 In those cases, the
status of an appropriation as one-year, multi-year, or no-year funds will be apparent from the
statute.
However, it is possible for an unnumbered paragraph to omit reference to any duration; the
paragraph might instead state only the amount of the appropriation and the objects for which it is
available.153 In those circumstances, and depending on the regular appropriations act at issue,
several features of statute may interact to supply the duration that is missing from the
unnumbered paragraph.
The style and title of a regular appropriations act, part of its prefatory matter, recites that the act
makes appropriations for a particular fiscal year ending September 30.154 Moreover, according to
a statutory rule of construction that applies to appropriations generally, “an appropriation in a
regular, annual appropriation law may be construed to be permanent or available continuously”
only if the appropriation is for particular objects or “expressly provides that it is available after
the fiscal year covered by the law in which it appears.”155 Together, according to the Government
Accountability Office (GAO), these two provisions create an “implication of fiscal year
availability” for those appropriations made in an appropriations act that lack an express
duration.156 Where no duration is stated, at least as an initial matter, the appropriation is a oneappropriation account”).
150 A multi-year appropriation might be available until the end of a subsequent fiscal year, but it is not necessarily the
case that the period of availability of multi-year appropriations is measured in whole fiscal years. See GAO GLOSSARY,
supra note 1, at 22 (including forward funding as a type of multiyear authority).

year appropriation, available for obligation only through the end of the fiscal year for which the
regular appropriations act makes appropriations.157
There is a potential qualification to this “implication of fiscal year availability” though. Before
Congress makes an appropriation in a regular appropriations act, it typically enacts a statute
authorizing appropriations.158 This statute might state the duration of the budget authority whose
appropriation it authorizes, including multi-year or no-year durations. Later, Congress might then
reference the authorizing statute—the one authorizing appropriations of more than one fiscal
year’s duration—when making an appropriation that does not, itself, state a duration.159
A reference of this type in the appropriation to an authorizing statute usually identifies the object
for which the appropriation is available (e.g., for a particular type of direct loan).160 The reference
might also be understood to supply the appropriation’s missing duration. Absent evidence of
legislative intent to the contrary, a specific reference “to an authorization act which provides that
appropriations made pursuant thereto shall remain available for longer than 1 year” might operate
“to incorporate the provisions of the authorizing act into the provisions of the appropriation.”161
GAO has considered such incorporation by reference “sufficient to overcome the implication of
fiscal year availability.”162
This approach to imputing the duration of an authorization of appropriations to a later
appropriation that specifically references the authorizing statute may not always align with
congressional intent, a point emphasized by the House Appropriations Committee in 1965. A
House-drafted supplemental appropriations measure carried a “new general provision” that would
have the effect of limiting the time period within which the bill’s appropriations could be
obligated. The new general provision stated that “[n]o part of any appropriation contained in this
Act shall remain available for obligation beyond the current fiscal year unless expressly so
provided herein.”163 The Committee recommended the provision by noting varying ways in which
authorizations of appropriations addressed duration.164 “The result” of this perceived

inconsistency, the Committee continued, “has been occasional confusion, more frequent
uncertainty, and, sometimes, ‘no-year availability’ when the Committee thought, from the terms
of the budget and appropriation bill language, that a one-year appropriation was being made.”165
The purpose of the new provision was to “provide control” of budget authority duration “wholly
within the language of the Act in which the appropriation is carried.”166 If an act included the new
general provision, the reader could determine the duration of budget authority by looking to the
regular appropriations act alone, without having to consider potential interactions between the
appropriation and its corresponding authorization.167
Most modern-day regular appropriations acts include a similar provision, directing that the act’s
appropriations do not remain available beyond the fiscal year covered by the appropriations act
unless the act expressly provides otherwise.168 When a regular appropriations act includes this
provision and makes an appropriation with no stated duration, the appropriation is available for
obligation for the current fiscal year only. The terms of particular appropriations are read in the
context of the statute in which they appear.169 Thus, while a particular appropriation (e.g., the
principal clause of an unnumbered paragraph) might lack a statement of duration, the
appropriation is read in context with other parts of the act, including a general provision that
states that no part of any appropriation provided in the act remains available for obligation
beyond the current fiscal year unless the act expressly provides a longer period of availability.170
This one-year availability applies even if the appropriation specifically references a statute that
authorizes appropriations of greater duration.171 In that case, the authorizing statute contemplates
(for example) a no-year duration, and the appropriations act states a one-year duration. As the last
enacted of the two statutes, the appropriations act will likely control and specify the
appropriation’s duration.172

Duration’s Effect on Agency Obligations
Perhaps the more important question posed by the duration of an appropriation is the effect that
duration has on an agency’s ability to use appropriated amounts to meet its expenses. An
appropriation’s period of availability provides that the amounts are “to remain available” until a
structuring the sterotyped [sic] appropriation authorization sections of basic legislative enactments.”).
165 Id. For example, in 1963, the House Appropriations Committee wrote that it was “astonished to learn” that the
Department of Health, Education, and Welfare viewed a particular appropriation, which had no stated duration but was
made pursuant to a no-year authorization, as being available for obligation on a no-year basis. See H.R. Rep. No. 881040, at 55–56 (1963) (urging revisions or updates to the predecessor statute of 31 U.S.C. § 1301(c) “to make its scope

fixed date or indefinitely. This limitation is substantially more complex than a mere deadline for
obligating federal funds. Rather, for certain appropriations, a provision of permanent law, the socalled “time statute,”173 requires an agency to consider the nature of the expenses or contracts that
it proposes to fund from a given appropriation, to determine whether, as a temporal matter, the
appropriation is available for the expense or contract.
The time statute originated in a provision enacted in 1870 to address the Civil War’s fiscal
effects.174 As it does today, Congress at that time appropriated funds for the general support of the
government, in part, on an annual basis.175 According to Senator John Sherman, those annually
voted sums, more than $111 million in FY1870, were “all that was required really for the
expenses of the Government in the opinion of Congress.”176 However, though prior statutes
generally stated that annually appropriated amounts were for the “service” of a given fiscal
year,177 Congress was understood to have given agencies some leeway in retaining, year to year,
the unexpended balances of prior-year appropriations.178 At the end of one fiscal year the
unexpended balance of such “old” appropriations (i.e., those made in a prior fiscal year’s
appropriations act) were understood to potentially augment the agency’s “new” appropriations
(i.e., those made for the current fiscal year).179 By FY1870, according to Senator Sherman funds
had thus accumulated so that federal agencies had available to them remaining, prior fiscal year
appropriations of more than $102 million, on top of the $111 million amount that Congress had
appropriated for that fiscal year.180 In the opinion of at least some Members, this perceived
flexibility undermined Congress’s control over agency spending.181

had “sprung up only since the war”); see also Law of July 12, 1870, ch. 251, 16 Stat. 230, 251.
175 Then as now, Congress also funded government programs using permanent appropriations. See, e.g., Law of March
3, 1849, ch. 129, 9 Stat. 414, 414–15 (permanent appropriation for paying compensation to military service members

specifically for the service of that year be used only to pay expenses incurred in that year or to
fulfill contracts properly made for that year.182 The 1870 amendment directed the return to the
Treasury of any balances not needed to pay such expenses.183 The time statute of today contains
substantially the same directive: “The balance of an appropriation or fund limited for obligation
to a definite period is available only for payment of expenses properly incurred during the period
of availability or to complete contracts properly made within that period of availability and
obligated consistent with section 1501 of this title.”184
The time statute confines use of a fixed-period appropriation to obligations incurred during the
appropriation’s period of availability.185 After the end of that period (i.e., after September 30 of a
given fiscal year for one-year funds appropriated for that fiscal year), the appropriation is said to
“expire” and cannot be used to incur new obligations.186 Expired appropriations are available only
to record or adjust obligations that were properly chargeable to the appropriation or to liquidate
such obligations.187 Suppose, for example, that an administrative panel resolves a labor dispute by
ordering an agency to provide uniforms or uniform allowances to designated employees.188 Under
the statutory framework, this order establishes an obligation.189 If the agency failed to record that
obligation against an appropriation before the appropriation expired, it may use the expired
appropriation to reflect the obligation that was actually incurred during its period of
availability.190 The agency may not use the expired appropriation to incur a new obligation.191 It

may not, for example, enter into a contract for the first time on October 14 of a given year and
record the obligations thus assumed against the unobligated balances of an appropriation that
expired two weeks earlier, on September 30.
Under the time statute, however, it is not enough for an agency to incur an obligation during an
appropriation’s period of availability.192 The time statute refers to particular types of expenses and
contracts as permissible of fixed-period appropriations—those expenses “properly incurred” or
those contracts “properly made” during the appropriation’s period of availability.193 GAO has
derived from the time statute a “bona fide needs rule”: “contracts executed and supported under
authority of fiscal year appropriations can only be made within the period that such funds are
available for obligation and may be made only to meet a bona fide need arising within that
period.”194 The bona fide needs rule generally applies to all federal government activities carried
out with fixed-period appropriations,195 whether those activities occur by way of a contract with a
nonfederal party,196 an interagency agreement,197 a cooperative agreement,198 or a grant.199
The concept of severability is key to deciding whether an expense incurred or contract formed
using a particular fixed-period appropriation meets a need that arises during the period in which
the appropriation was available for obligation—for example, whether funds available until
September 30, 2021, are used to meet a need that arises on or before that date. Services are either
severable or nonseverable, and the nature of the work funded determines which category a service
fits.200
A severable service meets a continuing or recurring need of an agency.201 Though an agency
might enter into a single contract for a year’s worth of such services, performance of the services

is able to be separated into independent components.202 The agency derives value when each such
component is performed.203 For example, gardening or window-washing services benefit the
agency each time the services are performed.204 The agency must fund these components using a
fixed-period appropriation that is current—that is, still available for obligation—when the
component is performed.205 Thus, an agency generally may not obligate a fixed-period
appropriation for the cost of severable services that will be performed after the end of the
appropriation’s period of availability.206
Nonseverable services are not capable of being divided in the same manner as severable services.
As a general matter, a nonseverable service calls for the creation of an end product.207 While the
agency or its contractor might develop that end product in stages or phases, unlike with a
severable service the agency derives no independent benefit from the completion of those
preliminary stages or phases.208 The agency’s need is instead met only when the entire task is
performed.209 For example, an agency needing a new data retrieval system will not see that need
met until the system is operational—a half-completed, nonfunctioning system does not meet the
agency’s needs.210 Unlike severable services, so long as a need for the nonseverable service exists
and an obligation is incurred when a fixed-period appropriation is available for obligation, an
agency may use the appropriation to pay for work performed in a later fiscal year, even after the
appropriation expires.211 The work that will be performed in the later fiscal year is considered
“not severable from the portion performed” in the current fiscal year.212
Obligations for federal assistance programs, which take the form of a grant or cooperative
agreement, present a special type of bona fide needs analysis. When an agency makes a grant or
cooperative agreement, it awards funds to a third party recipient for the recipient’s use in carrying

out a stated public purpose.213 The funds recipient will then later use those funds to cover the cost
of goods and services needed to carry out that public purpose.
In reviewing agency obligations for federal assistance programs, GAO once considered whether
the uses to which a recipient dedicated federal funds resembled severable services, which GAO
opined could be supported only by grant or cooperative agreements awards made on an annual
basis.214 More recent decisions, though, draw a distinction between the agency’s use of
appropriated funds to make a grant or cooperative agreement award and the recipient’s
subsequent use of the funds. The agency’s need under a financial assistance program is to extend
funds to a recipient, and that need is met when the agency incurs an obligation to the recipient
under a grant or cooperative agreement.215 For purposes of the bona fide needs rule, it “does not
matter” when the recipient, in turn, uses the funds to carry out the stated public purpose.216 Thus,
so far as the time statute is concerned, and assuming an agency has the need to make grants in the
fiscal year when an appropriation is still current, an agency may obligate a fixed-period
appropriation to award funds that the recipient could not first use until the following fiscal year217
or to make a multiple-year grant award.218

Determining Effects on Substantive Law
The chief function of a regular appropriations act is the granting of budget authority.219 This focus
results in part from chamber rules. Since the mid-1800s chamber rules have encouraged Members
to separate decisions of whether and how Congress should authorize particular agency functions
from decisions of whether Congress should fund such authorized functions.220 More specifically,
chamber rules generally prohibit “legislation on appropriations measures.”221 For example, it is
213 An agency is to enter a cooperative agreement with a funds recipient when the agency expects that it will be

substantially involved in carrying out the award. An agency is to enter a grant agreement when it does not expect to be
substantially involved in carrying out the award. See 31 U.S.C. §§ 6304, 6305 (setting criteria for use of a grant
agreement or a cooperative agreement).

program may, however, impose limits on the duration of a grant or cooperative agreement. See Dep’t of Educ.—Grant

provoke controversy.”).

generally not in order for an Appropriations Committee to report a regular appropriations bill that
includes a provision expanding the authority granted to an agency under other law, and one
Member may raise a point of order if another Member offers such a provision as an amendment
to a regular appropriations bill.222
So far as chamber rules are concerned, Congress in most cases is to make “money” and “policy”
decisions separately, the former in appropriations acts and the latter in other statutes.223 Even so,
regular appropriations acts commonly include matter that is alleged to affect what the courts often
label as “substantive law.” For example, an agency or litigant might cast Congress’s decision to
fund or not fund a particular obligation or activity as having changed the substantive law
underlying that obligation or activity. Likewise, provisos or general provisions are often said to
effect changes in substantive law.
To assess claims that a provision in a regular appropriations act alters substantive law, courts
apply legal presumptions about a provision’s intended meaning. These presumptions are born of
courts’ understanding of the purpose and procedure behind regular appropriations acts. The
presumptions address two questions: the effect, if any, of a provision on substantive law, and the
duration of any such effect.

Effects of Appropriations Act on Substantive Law
Case law interpreting the effect of regular appropriations act matter on “substantive law” typically
does not expressly define that phrase. In general terms, substantive law means provisions of law
fixing rights, duties, or obligations.224 The phrase’s use in the appropriations context is similar to
this general definition. When courts refer to the effect of a regular appropriations act on
“substantive law,” the courts mean (for example) those provisions of statute authorizing agency

but are not limited to, regular appropriations measures. See id. at 1 nn. 4, 9 (explaining that in the House “general
appropriations bills are the annual appropriations acts (or any combination thereof) and any supplemental
appropriations acts that cover more than one agency” while in the Senate such measures include regular and
supplemental appropriations bills as well as continuing appropriations bills that cover more than one agency or
purpose).
222 See id. at 14 (“Limitations cannot expand the discretion previously provided in law to an official or agency to
include actions not currently authorized, even if those actions are not explicitly prohibited by existing law.”).
223 See Andrus v. Sierra Club, 442 U.S. 347, 361 (1979) (stating that the distinction in chamber rules between
“legislation” and “appropriations” encourages “program and financial matters” to be “considered independently of one
another. This division of labor is intended to enable the Appropriations Committees to concentrate on financial issues
and to prevent them from trespassing on substantive legislation.” (internal quotation marks omitted)).
224 See, e.g., Substantive Law, BLACK’S LAW DICTIONARY (11th ed. 2019) (“The part of the law that creates, defines,
and regulates the rights, duties, and powers of parties.”).

functions,225 imposing duties on agencies,226 or creating rights in third parties.227 Most of the time,
Congress establishes substantive law by enacting a statute other than an appropriations act.228
When the question is whether matter in an appropriations act affects provisions of statute
establishing substantive law, courts employ presumptions that are born of courts’ understanding
of the purpose and procedure behind regular appropriations acts.229 The Supreme Court has thus
distinguished between “substantive enactments and appropriations measures.”230 Both are “Acts
of Congress,” but appropriations acts are understood to have “the limited and specific purpose of
providing funds for authorized programs.”231 It is also true, though, that Congress regularly alters
substantive law in appropriations acts,232 and nothing in the Constitution requires it to make only
“money” decisions in appropriations acts.233

225 See, e.g., United States v. Burton, 888 F.2d 682, 687 (10th Cir. 1989) (per curiam) (noting that while provisions of

permanent law allowed the General Services Administration (GSA) to appoint police officers to patrol federal property
only if the federal government had acquired criminal jurisdiction over that property an appropriations act granted GSA
additional authority to appoint police officers even as to federal property for which no such criminal jurisdiction had
been acquired); Donovan v. Carolina Stalite Co., 734 F.2d 1547, 1558 (D.C. Cir. 1984) (considering the effect of a
limitation on funding contained in an appropriations act on the Department of Labor’s “statutory basis for enforcement
litigation” under the Federal Mine Safety and Health Act).
226 See, e.g., City of Chicago v. U.S. Dep’t of Treasury, Bureau of Alcohol, Tobacco & Firearms, 423 F.3d 777, 781
(7th Cir. 2005) (concluding that a proviso in a regular appropriations act amounted to a “change in substantive FOIA
law in that it exempts from disclosure data previously available to the public under FOIA”); Pontarelli v. U.S. Dep’t of
the Treasury, 285 F.3d 216, 231 (3d Cir. 2002) (concluding that a proviso barring use of a Bureau of Alcohol, Tobacco,
and Firearms (ATF) funds to investigate or act upon an application for relief from firearms disabilities prevented ATF
from denying such applications and thus prevented federal courts from reviewing applications as an ATF denial was
required for judicial review).
227 See, e.g., Kane Cty. v. United States, 136 Fed. Cl. 644, 649 (2018) (examining whether a regular appropriations act

governments to compensate for tax revenue lost on account of tax-exempt federal lands within the local governments’
territorial jurisdiction).
228 Courts decide whether matter in an appropriations act alters preexisting substantive law using the same
presumptions, detailed below, whether or not the substantive law was established in an appropriations act or in another
statute. See, e.g., Ctr. for Investigative Reporting v. U.S. Dep’t of Just., 982 F.3d 668, 681 (9th Cir. 2020) (finding that

to prevent one phrase from being trademarked could create an allegedly unduly complex trademark scheme).

Regular Appropriations Acts: Selected Statutory Interpretation Issues

Given this understanding of the normally limited function of matter in an appropriations statute,
courts have developed a “very strong presumption” against finding that Congress changed
substantive law by means of an appropriations act.234 Congress “may amend substantive law in an
appropriations statute, as long as it does so clearly.”235 Thus, courts will find that matter in an
appropriations act alters substantive law when that outcome is the only reasonable interpretation
of the appropriations act.236 Courts have justified this reluctance to find substantive law changes
in appropriations acts by referring to the perceived unpredictability that a less-demanding
standard would yield.237
Most frequently, courts consider whether Congress’s decision to appropriate, or not appropriate,
funds for a given purpose itself constitutes a change in law. Thus, when substantive law fixes a
definite salary for an officer or employee,238 or directs an agency to make payments to health
insurers,239 or establishes protections for wildlife that would prevent an agency action,240 a litigant
might contend that Congress’s later decision of whether to fund these obligations or activities
amounts to a change in preexisting law. If Congress funds less than the amount fixed in law for an
employee’s salary,241 or bars the use of funds for payments,242 or all
