Congressional Court Watcher: Recent 
Appellate Decisions of Interest to Lawmakers 
(May 15–May 21, 2023), Part 2 
May 22, 2023 
The federal courts issue hundreds of decisions every week in cases involving diverse legal disputes. This 
Sidebar series selects decisions from the past week that may be of particular interest to federal lawmakers, 
focusing on orders and decisions of the Supreme Court and precedential decisions of the courts of appeals 
for the thirteen federal circuits. Selected cases typically involve the interpretation or validity of federal 
statutes and regulations, or constitutional issues relevant to Congress’s lawmaking and oversight 
functions. 
Some cases identified in this Sidebar, or the legal questions they address, are examined in other CRS 
general distribution products. Members of Congress and congressional staff may click here to subscribe to

attorneys. 
This week’s Congressional Court Watcher is divided into two parts because of the number of notable 
decisions issued over the past week. This Sidebar (Part 2) discusses activity by the U.S. courts of appeals 
from May 15 through May 21, 2023, while a companion Sidebar addresses Supreme Court decisions from 
that period. 
Decisions of the U.S. Courts of Appeals 
Topic headings marked with an asterisk (*) indicate cases where the appellate court’s controlling opinion 
recognizes a split among the federal appellate courts on a key legal issue resolved in the opinion, 
contributing to a non-uniform application of the law among the circuits. 
•  *Arbitration: The First Circuit split with the Second Circuit after it considered the 
interplay between Puerto Rico law, a federal statute, and a U.S. treaty when affirming a 
district court’s order to compel arbitration in an insurance dispute. The panel held that a 
provision in the Convention on the Recognition and Enforcement of Foreign Arbitral 
Awards directing courts to channel covered disputes to arbitration was self-executing,

meaning it was enforceable by U.S. courts without need of implementing legislation 
(Green Enter., LLC v. Hiscox Syndicates Ltd. at Lloyd's of London). 
•  Civil Rights: In a case under the Americans with Disabilities Act (ADA), the Eighth 
Circuit held that a railroad company may refuse to allow a worker to bring his Rottweiler 
service dog onto moving freight trains. The employee did not claim that the refusal 
limited his performance of essential work functions, but claimed that he was denied a 
“fringe benefit” and privilege of employment. The circuit court agreed that the ADA 
applied to employment discrimination in the provision of benefits, such as denying equal 
access to employee lounges and facilities. Even so, the court ruled that allowing a service 
dog at work so that an employee could have the same assistance provided by the service 
dog outside of work was not a cognizable benefit or privilege of employment under 
ADA-implementing regulations (Hopman v. Union Pac. R.R.). 
•  Election Law: The Fifth Circuit allowed state lawmakers to invoke legislative privilege 
to refuse to produce documents related to amendments to Texas voting laws, which the 
United States and other plaintiffs claimed were racially discriminatory. The court 
described the scope of the legislative privilege as broad, potentially including 
communications with third parties, such as lobbyists and advocacy groups, during the 
regular scope of legislative business. The court also suggested that exceptional 
circumstances, like a federal criminal prosecution, may overcome such claims of 
legislative privilege in other cases (La Union Del Pueblo Entero v. Abbott). 
•  Energy: The D.C. Circuit partially vacated a Pipeline and Hazardous Materials Safety 
Administration (PHMSA) rule requiring installation of remote-controlled or automatic 
shut-off valves in some new or replaced gas and liquid pipelines. The court held that the 
PHMSA did not exceed its statutory authority in issuing the rule. However, the court 
decided that the agency unlawfully failed to disclose the economic basis for applying the 
rule to “gathering” pipelines that collect raw gas and crude oil from wells, and that 
PHMSA failed to make a reasoned determination that regulating gathering pipelines was 
appropriate (GPA Midstream Ass'n v. U.S. Dep't of Transp.). 
•  Environmental Law: The Ninth Circuit affirmed in part and vacated in part lower court 
rulings on the Forest Service’s decision to conduct treatments (including thinning and 
prescribed burns) on several thousand acres of national forest in Idaho to reduce risks of 
wildfire and disease. To satisfy the requirements of the National Environmental Policy 
Act (NEPA), the Forest Service invoked a categorical exclusion established in the 
Healthy Forests Restoration Act (HFRA). The categorical exclusion created in the HFRA 
is limited to “areas in the wildland-urban interface,” which has a specific meaning under 
the HFRA. The Ninth Circuit affirmed the lower court’s decision that the Forest Service 
had committed a clear error in judgment by relying on an alternate definition of 
“wildland-urban interface” contained in a community plan. However, the appellate court 
also found that the district court had not correctly interpreted the HFRA and thus vacated 
the lower court’s preliminary injunction blocking implementation of the project (All. for 
the Wild Rockies v. Petrick). 
•  Environmental Law: The Ninth Circuit ruled that the U.S. Fish and Wildlife Service’s 
(FWS’s) designation of certain areas in southern Arizona as unoccupied critical habitat 
for jaguar under the Endangered Species Act (ESA) violated the ESA and Administrative 
Procedure Act. The ESA provides that areas occupied by a listed species at the time of 
listing may be designated as critical habitat, but that FWS did not have adequate evidence 
that the jaguar occupied the designated area. An area not occupied by the species may 
also be designated if it is “essential for the conservation of the species.” The court

concluded that an area must be “indispensable,” not merely beneficial, to the species’ 
survival and recovery to qualify as “essential,” and that FWS had failed to demonstrate 
that the designated areas were indispensable (Ctr. for Biological Diversity v. FWS). 
•  Environmental Law: The D.C. Circuit rejected a challenge to a decision by the Federal 
Energy Regulatory Commission (FERC) to authorize construction of liquefied natural gas 
facilities in the Alaska North Slope. Petitioners argued that FERC did not comply with 
NEPA and its implementing regulations when authorizing the construction. The court 
held that it lacked jurisdiction to consider some of these arguments, where petitioners had 
not first exhausted their administrative remedies and, for those claims where the court 
had jurisdiction, the plaintiffs’ arguments failed on the merits (Ctr. for Biological 
Diversity v. FERC). 
•  Immigration: The Tenth Circuit held that a “zipper clause” in federal immigration law, 8 
U.S.C. § 1252(b)(9), did not strip the district court of jurisdiction over a challenge by an 
alien to the United States Citizenship and Immigration Services’ decision to terminate 
both her and her son’s refugee status. Section 1252(b)(9) limits federal court review of 
issues “arising from any action taken or proceeding brought to remove an alien,” except 
as part of the review of a final order of removal. The court held that neither § 1252(b)(9) 
nor its implementing regulations covered the termination of refugee status (Mukantagara 
v. U.S. Dep't of Homeland Sec.). 
•  Immigration: The Eleventh Circuit held that an immigration judge and the Board of 
Immigration Appeals misconstrued a provision of the Violence Against Women Act of 
1994 that governed an alien petitioner’s request for cancellation of removal. The 
provision, 8 U.S.C. § 1229b(b)(2)(A)(i), requires the petitioner to show that she “has 
been battered or subjected to extreme cruelty” by a spouse or parent. The court held that 
the administrative adjudicators erred by reading the term “extreme cruelty” to require 
proof of physical abuse, when mental or emotional abuse could also suffice. The panel 
remanded the case to the Board for further consideration (Ruiz v. U.S. Att’y Gen.). 
•  Labor & Employment: A divided Second Circuit allowed a class-action suit by former 
employees of a restaurant located within a casino to proceed under the Worker 
Adjustment and Retraining Notification Act (WARN Act) and corresponding state law. 
The majority held that a genuine issue of material act existed on whether the restaurant 
was an “operating unit” under the WARN Act and implementing regulations, in which 
case the employees would have been entitled to 60 days’ notice before the closing of the 
restaurant. The majority concluded that whether an entity was an operating unit under the 
Act was a fact-specific determination, and that whether the restaurant could operate 
independently from the casino was not dispositive in deciding if it was operationally and 
organizationally distinct from the casino (Roberts v. Genting New York LLC). 
•  *Labor & Employment: The Sixth Circuit announced a rule on when a district court 
should facilitate notice to “similarly situated” current and former workers that might 
allow them to join a plaintiff’s suit for unpaid wages under the Fair Labor Standards Act. 
The circuit court held that for a district court to facilitate notice, the plaintiff must show a 
strong likelihood that those employees are similarly situated. The court characterized this 
standard as more stringent than the standard adopted by many district courts, under which 
the plaintiff must first make only a modest factual showing that the employees are 
similarly situated. The panel also described the announced standard as less stringent than 
the standard endorsed by the Fifth Circuit, which requires a showing by a preponderance 
of evidence that others are similarly situated (Clark v. A&L Homecare and Training, Ctr.).

•  Separation of Powers: The Ninth Circuit held that a district court abused its discretion 
by disqualifying the whole U.S. Attorney’s Office in the District of Arizona from 
prosecuting a case against multiple criminal defendants, when those defendants alleged 
that a single Assistant U.S. Attorney in that Office engaged in potential misconduct. The 
circuit court recognized that separation of powers considerations made the judicial 
disqualification of an entire U.S. Attorney’s Office an extreme remedy that was available 
in extraordinary circumstances not arising here (United States v.Williams). 
•  Tax: The Ninth Circuit considered the scope of an Internal Revenue Code provision, 26 
U.S.C. § 6324(a)(2), which makes certain persons liable for unpaid federal estate taxes. 
Section 6324(a) applies to a covered person who “receives, or has on the date of the 
decedent’s death, property included in the gross estate.” The issue before the court was 
whether “on the date of the decedent’s death” modified only the immediately preceding 
verb “has” or also modified “receives”; that is, whether the provision applied to those 
who “receive” covered estate property at any time or only “on the date of the decedent’s 
death.” Agreeing with the United States, the majority held that the most natural reading of 
Section 6324(a)(2), given its structure and punctuation, is that persons who receive 
covered estate property, whether at the time of the decedent’s death or any time after, are 
personally liable for unpaid estate taxes, subject to the statute of limitations (United 
States v. Paulson).
