Judicial Review of Actions Legally Committed 
to an Agency’s Discretion 
September 17, 2020 
Individuals and entities affected by a federal agency’s action sometimes may be able to challenge that 
action in federal court. In some cases, an agency’s governing statute specifically authorizes affected 
parties to bring suit challenging a particular agency action. But even when specific statutory authority is 
unavailable, 
a person generally can challenge a
n agency’s action in federal district court under the 
Administrative Procedure Act (APA). On review, the APA empowers courts t
o set aside agency action that 
is, among other things, “arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with 
law.”  
The Supreme Court has explained that the APA “embodies the basi
c presumption of judicial review” of 
agency action, meaning that judicial review under the APA generally will be available to a party. But not 
every legal challenge of an agency’s action is reviewabl
e. Constitutional and prudential considerations 
may limit when a court will entertain such a suit
. Jurisdictional requirements must also be satisfied.  
T
he APA itself limits judicial review of certain types of agency action. Specifically, the APA bars judicial 
review of an agency’s action when (1) a particular statute precludes review of that action or (2) the action 
“is committed to agency discretion by law.” While the first exception applies when a statute reflects 
Congress’s intent to preclude judicial review, the second—codified at 5 U.S.C. § 701(a)(2)—often 
requires a more searching examination about whether “the statute is drawn so that a court would hav
e no 
meaningful standard against which to judge the agency’s exercise of discretion.” (The APA also bars 
judicial review in other ways, including by limiting court review to agency actions that are 
“final.”) 
Some commentators have criticized the Supreme Court’s general approach to assessing when a particular 
action is committed to agency discretion under Section 701(a)(2), which typically consists of reviewing 
an underlying statute to determine if guidelines or standards exist that allow judicial evaluation of the 
action. But the Court’s approach offers Congress guidance for crafting statutes in a way that reviewing 
courts may read as preventing or, alternatively, authorizing court review of particular actions.  
The Supreme Court’s Interpretation of Section 701(a)(2) 
The Supreme Court has often been tasked with considering whether an agency’s action has been 
“committed to agency discretion” under Section 701(a)(2). In

the Court emphasized that the provision provides a “very
 narrow” exception to the presumptive 
reviewability of agency action under the APA. In
 that and later
 cases, the Court has described Section 
701(a)(2) with reference to Section 706 of the APA, which gives courts the power to review agency 
actions for 
“abuse of discretion.” The Court has
 explained that judges cannot determine if an agency has 
abused its discretion without “judicially manageable standards”; an action is deemed as “committed to 
agency discretion by law” when the authorizing statute is “drawn in such broad terms that in a given case 
there is no law to apply.”  
The Supreme Court
 typically has construed Section 701(a)(2) to cover actions that courts 
“traditionally” 
have considered unreviewable. One such category concerns an agency’s decision to refuse to institute 
enforcement proceedings. In 
Heckler v. Chaney, the Court
 held that judicial review of such decisions 
generally was inappropriate for several
 pragmatic reasons.
 First, the Court explained that such decisions 
typically involve “a complicated balancing of a number of factors which are peculiarly within [the 
agency’s] expertise,” including whether the agency has sufficient resources to pursue enforcement.
 Next, 
while acknowledging that an agency’s affirmative enforcement action supplies a basis for court review, 
the Court reasoned “that when an agency refuses to act it generally does not exercise its
 coercive power over an individual’s liberty or property rights,” rights that parties regularly ask courts to safeguard. An 
agency’s enforcement action, the Court reasoned, “at least can be reviewed to determine whether the 
agency exceeded its statutory powers.” Lastly, the Court believed that an agency’s non-enforcement 
decision was similar in some respects to a federal prosecutor’s decision not to issue an indictment. The 
latter decision, wrote the Court, “has long been regarded as the special province of the Executive 
Branch.” 
The Court in 
Chaney did not hold that judicial review of agency non-enforcement decisions was always 
unavailable. Instead, the Court characterized such decisions as
 presumptively unreviewable, but 
recognized that “the presumption may be rebutted where the substantive statute [at issue] has provided 
guidelines for the agency to follow in exercising its enforcement powers.” If Congress has “indicated an 
intent to circumscribe agency enforcement discretion” and “provided meaningful standards for defining 
the limits of that discretion,” the 
Chaney Court
 explained, the statute will supply the “law” sufficient to 
enable a court to review an agency’s non-enforcement decision. The Court also identified other situations 
that might possibly rebut the presumption of unreviewability of non-enforcement decision
s, including 
where an agency “consciously and expressly” adopts a non-enforcement policy “so extreme as to amount 
to an abdication of its statutory responsibilities.” 
Over the years, the Court has
 recognized other types of agency decisions that fall within Section 
701(a)(2)’s ambit. I
n Webster v. Doe, the Court held that the decision of the Director of the Central 
Intelligence Agency (CIA) to dismiss an employee due to his sexual orientation was
 shielded from review 
(except 
on constitutional grounds) where a statute had
 provided that the “Director may, in his discretion, 
terminate [a CIA employee or officer] whenever he shall deem such termination necessary or advisable in 
the interests of the United States.” Additionally, in
 Lincoln v. Vigil, whil
e noting that agencies may not 
“disregard statutory responsibilities,” the Court
 held that an agency’s distribution of money from a lump-
sum appropriation is “traditionally regarded as committed to agency discretion.” The Court has also found 
a 
“tradition of nonreviewability” in an agency’s refusal to reconsider a prior decisi
on when the petition 
for reconsideration was based “on the same record that was before the agency when it rendered its 
original decision.”  
The Court has identified many types of agency actions that are 
not exempt from review under Section 
701(a)(2). For example, the Court recently
 held that statutory and constitutional challenges may be 
brought against census-related decisions by the Department of Commerce, as the taking of the census is 
not a matter committed to agency discretion. And i
n Department of Homeland Security (DHS) v. Regents 
of the University of California, the Court held that DHS’s rescission of the Deferred Action for Childhood 
Arrivals (DACA) program was
 reviewable, explaining that DACA 
“created a program for conferring

affirmative immigration relief” and that, therefore, its rescission “‘provides a focus for judicial review.’”

Violated the APA, by Ben Harrington.)  
Criticism of the Supreme Court’s Interpretation of Section 701(a)(2) 
As explained above, when the Supreme Court has analyzed whether Section 701(a)(2) bars judicial 
review of an agency’s action, it generally seeks to determine if the underlying statute is 
“drawn in such 
broad terms that in a given case there is no law to apply.” When a statute lacks helpful guideposts to 
support judicial evaluation of an agency’s action, the relevant action is “committed to agency discretion 
by law” and therefore may not be reviewed by the court. 
Commentators have criticized the Court’s interpretation and application of Section 701(a)(2) on 
a variety 
of grounds, including
 constitutional ones. For example, in hi
s dissent in 
Webster v. Doe, Justice Scalia 
criticized the “no law to apply” test for being
 underinclusive of the variety of actions courts traditionally 
hold are not subject to review. He argued that the “law” in Section 701(a)(2)’s “committed to agency 
discretion by law
” embraces a “body of jurisprudence” that includes “principles ranging from the 
‘political question’ doctrine, to sovereign immunity . . ., to official immunity, to prudential limitations 
upon the courts’ equitable powers, to what can be described no more precisely than a traditional respect 
for the functions of the other branches” of government. This large body of
 judicial-review common law, 
remarked Justice Scalia, 
“cannot possibly be contained within the phrase ‘no law to apply.’” 
Relatedly, some commentators hav
e argued that the “no law to apply” language is too restrictive. One 
scholar
 contended that a test that limits judicial review to instances where there is “law to apply” conflicts 
with the APA’
s abuse-of-discretion standard of judicial review. Whether an agency abused its discretion, 
he
 wrote, is often “a matter for 
judicial discretion” and “may not be guided by law.” As another 
commentator has
 explained, judicial review under the abuse-of-discretion standard often does not concern 
whether an agency complied with relevant statutory factor
s, such as when courts examine whether an 
agency supplied adequate reasons for changing course from a prior policy.  
Critics have also opined that, while the Court typically recites the “no law to apply” test (or 
“no 
meaningful standard” language) in its Section 701(a)(2) analyses, it has often rested its ultimate 
determinations of an action’s nonreviewability
 on other or additional factors. For example, the Court in 
Chaney discussed several pragmatic considerations for why agency non-enforcement decisions are 
presumptively unreviewable that were not explicitly related to the presence of helpful legal guideposts for 
judicial review.  
Considerations for Congress 
As discussed, the standard the Court generally applies in determining whether an agency action is 
unreviewable under Section 701(a)(2) is whether there is “law to apply” by which to review the action or, 
put another way, whether a statute contains a “meaningful standard against which to judge the agency’s 
exercise of discretion.” Congress can expressly provide for or, conversely,
 preclude judicial review of an 
agency’s action in statute. However, if Congress does not include such an explicit grant or prohibition, it 
can seek to ensure parties may or may not challenge an agency’s action under the APA by setting forth 
additional standards and criteria for judicial review of agency actions. For example, a court may be more 
willing to review an agency’s decision not to pursue an enforcement acti
on if the governing statute 
imposes clear standards on the agency’s exercise of its enforcement discretion—i.e., how or when the 
agency is to initiate enforcement actions—or creates clear conditions that trigger enforcement actions. 
Relevant guidelines for judicial review may stem from sources 
other than Congress. The U.S. Court of 
Appeals for the District of Columbia Circuit looks not only to statutes for guidelines, but
 also to agency

 regulations and “other binding expressions of agency viewpoint.” Interpreting Section 701(a)(2) to allow 
such nonlegislative sources to supply the necessary “law” for reviewing agency actions imparts 
significant authority to administrative agencies. The existence of such standards, however, may not 
override Congress’s foreclosure of review of a particular type of action in statute. And Congress can, via 
statute, authorize or limit an agencies’ creation of such criteria in accordance with it
s authority to define 
and prescribe agencies’ powers and responsibilities. 
The Supreme Court’s “no law to apply” test stems from its interpretation of Section 701(a)(2). It is not 
based on constitutional considerations, and Congress can displace that test and any other judicial 
interpretation of Section 701(a)(2) by amending that section. If Congress eliminated the section from the 
APA, the only exception to judicial review contained in Section 701 of the APA would be for actions that 
ar
e precluded from review by statute (regardless of whether the action is committed to an agency’s 
discretion). Without Section 701(a)(2), courts would determine whether a specific action is reviewable by 
interpreting the text of the statute 
and also, perhaps, “the structure of the statutory scheme, its objectives, 
its legislative history, and the nature of the administrative action involved.” But reviewing courts would 
not, presumably, explicitly rely on the Court’s “no law to apply” test. Congress could also amend Section 
701(a)(2) to provide that it does or does not apply to certain types of actions (e.g., particular types of non-
enforcement decisions). Still, regardless of any legislative modifications, courts may conclude that 
constitutional and other considerations make judicial review of some agency actions inappropriate, even if 
review is no longer foreclosed by Section 701(a)(2).
