ORDER AND JUDGMENT * _________________________________
Before HARTZ, BACHARACH, and EID, Circuit Judges. _________________________________
This appeal involves whether the United States Bureau of Prisons (“BOP”) has
authority to discipline prisoners who, like appellant Willie Davis, are confined in a
federal correctional institution. In a pro se application for habeas corpus under
28 U.S.C. § 2241, Davis argued that the BOP did not have such authority and
therefore had improperly deprived him of earned good conduct time (“GCT”). The
After examining the briefs and appellate record, this panel has determined *
unanimously that oral argument would not materially assist in the determination of this appeal. See Fed. R. App. P. 34(a)(2); 10th Cir. R. 34.1(G). The case is therefore ordered submitted without oral argument. This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel. It may be cited, however, for its persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1. Appellate Case: 25-1273 Document: 34-1 Date Filed: 07/16/2026 Page: 2
district court rejected his argument, denied his application, and dismissed the action
with prejudice. Exercising jurisdiction under 28 U.S.C. § 1291, we affirm.
I
In 2009, Davis was convicted of multiple crimes and sentenced to a 216-month
term of imprisonment. In 2017, while serving that sentence, Davis was found guilty
of possessing contraband in prison and was sentenced to a 37-month consecutive
term of imprisonment. Based on his aggregated term of imprisonment, Davis was
eligible to earn 1,138 days of GCT. But due to numerous violations of institutional
rules and regulations, he has been disallowed 567 days of GCT and has forfeited 108
days of GCT, which resulted in a total loss of 675 days of GCT. He is currently
confined at the United States Penitentiary Administrative Maximum Facility
(“ADX”) in Florence, Colorado, and is scheduled to be released in January 2027.
In his § 2241 habeas application, Davis asserted that the BOP lacked authority
to deprive him of GCT. 1 His theory was based on the interplay between 18 U.S.C.
§§ 4042(a) and 4042(d). Section 4042(a)(1) provides that, “under the direction of the
Attorney General,” the BOP “shall . . . have charge of the management and regulation
of all Federal penal and correctional institutions.” To that end, § 4042(a)(3) requires
the BOP to “provide for the protection, instruction, and discipline of all persons
charged with or convicted of offenses against the United States.” § 4042(a)(3)
(emphasis added). Pursuant to § 4042(a)(3), the BOP promulgated the disciplinary

program it used to reduce Davis’s GCT. See 28 C.F.R. § 541.1. But § 4042(d)
provides an exception to the BOP’s statutory duties, including its disciplinary
power: “This section shall not apply to military or naval penal or correctional
institutions or the persons confined therein.” § 4042(d). 2 Davis alleged that the
ADX is among the “correctional institutions” included in § 4042(d) and therefore the
BOP lacked authority to use its disciplinary program to reduce his GCT credits. He
sought restoration of the lost GCT and immediate release from custody.
The government opposed the application. The district court agreed with the
government’s argument and denied relief. The court rejected Davis’s position “that
the use of the second ‘or’” in § 4042(d) “separates ‘correctional institutions’ from the
words ‘military or naval.’” R. at 322–23. The court concluded instead “that the
language of the statute makes clear that the word ‘correctional institution’ is
modified by ‘military or naval,’ such that § 4042(d) only applies to military or naval
correctional institutions.” R. at 323. The court explained that Davis “fail[ed] to
recognize that the statute uses the term ‘military or naval’ to describe the type of
‘penal or correctional institutions’ that are exempt from Section 4042.” Id. “As a
result,” the court concluded, § 4042(d) “does not apply to the ADX because the ADX
is neither a military correctional institution nor a naval correctional institution,” and
therefore “the BOP is authorized under Section 4042(a)(3) to implement regulations
2 Contrary to Davis’s contention, see Aplt. Reply Br. at 2, 5, there is no comma after the word “penal” in the statute. 3 Appellate Case: 25-1273 Document: 34-1 Date Filed: 07/16/2026 Page: 4
governing its inmate discipline program, which includes the authority to revoke GCT
credits.” Id.
Davis timely appealed.
II
In reviewing the denial of a § 2241 application, “we review the district court’s
legal conclusions de novo.” Leatherwood v. Allbaugh, 861 F.3d 1034, 1042
(10th Cir. 2017). Because Davis is pro se, we construe his filings liberally, but we
cannot act as his advocate. See Yang v. Archuleta, 525 F.3d 925, 927 n.1 (10th Cir.
2008).
“It is our primary task in interpreting statutes to determine congressional
intent, using traditional tools of statutory construction.” United States v. Manning,
526 F.3d 611, 614 (10th Cir. 2008) (internal quotation marks omitted). “We begin by
examining the statute’s plain language.” Id. “If the statutory language is clear, our
analysis ordinarily ends.” Id.; see also Edwards v. Valdez, 789 F.2d 1477, 1481
(10th Cir. 1986) (“It is a well established law of statutory construction that, absent
ambiguity or irrational result, the literal language of a statute controls.”).
We conclude § 4042(d)’s language is clear and unambiguous—the words
“military” and “naval” are adjectives that modify the phrase “penal or correctional
institutions.” Thus, § 4042 does not apply to “military . . . penal or correctional
institutions” or to “naval penal or corrections institutions.” We reject Davis’s
reading that the second “or” in the statute places “penal” and “correctional” in the
disjunctive, leaving “correctional institutions” as a stand-alone noun encompassing

In reviewing the denial of a § 2241 application, “we review the district court’s
legal conclusions de novo.” Leatherwood v. Allbaugh, 861 F.3d 1034, 1042
(10th Cir. 2017). Because Davis is pro se, we construe his filings liberally, but we
cannot act as his advocate. See Yang v. Archuleta, 525 F.3d 925, 927 n.1 (10th Cir.
2008).
“It is our primary task in interpreting statutes to determine congressional
intent, using traditional tools of statutory construction.” United States v. Manning,
526 F.3d 611, 614 (10th Cir. 2008) (internal quotation marks omitted). “We begin by
examining the statute’s plain language.” Id. “If the statutory language is clear, our
analysis ordinarily ends.” Id.; see also Edwards v. Valdez, 789 F.2d 1477, 1481
(10th Cir. 1986) (“It is a well established law of statutory construction that, absent
ambiguity or irrational result, the literal language of a statute controls.”).
We conclude § 4042(d)’s language is clear and unambiguous—the words
“military” and “naval” are adjectives that modify the phrase “penal or correctional
institutions.” Thus, § 4042 does not apply to “military . . . penal or correctional
institutions” or to “naval penal or corrections institutions.” We reject Davis’s
reading that the second “or” in the statute places “penal” and “correctional” in the
disjunctive, leaving “correctional institutions” as a stand-alone noun encompassing
4 Appellate Case: 25-1273 Document: 34-1 Date Filed: 07/16/2026 Page: 5
the ADX. That reading requires viewing “military” and either “naval” or “naval
penal” as nouns. But it would make no sense to say § 4042 “shall not apply to”
either “military” or “naval” or “naval penal,” because none of those constructs
identifies any sort of cognizable prison facility. Thus, under Davis’s reading,
“military” and either “naval” or “naval penal” would be meaningless, which is
contrary to the principle that “we are to give meaning to every word of a statute
where possible,” Smith v. Midland Brake, Inc., 180 F.3d 1154, 1165 (10th Cir. 1999)
(en banc).
Moreover, it would be nonsensical for Congress to mandate that the BOP
“shall . . . have charge of the management and regulation of all Federal penal and
correctional institutions,” § 4042(a)(1), and then take that mandate away in
§ 4042(d). Instead, it was necessary for Congress to make § 4042 inapplicable to
military or naval prisons because “Congress . . . created a military penal system
distinct from the BOP,” and although “the Attorney General directly controls the
BOP, military penal institutions fall outside his authority.” United States v. Joshua,
607 F.3d 379, 384 (4th Cir. 2010); see also 18 U.S.C. § 4001(b)(1) (“The control and
management of Federal penal and correctional institutions, except military or naval
institutions, shall be vested in the Attorney General . . . .” (emphasis added)). 3
3 Our rejection of Davis’s reading of § 4042(d) dispenses with his arguments that “Congress expressly chose to create . . . tension” between § 4042(d) and § 4001, Aplt. Opening Br. at 11, and that the district court exceeded its jurisdiction under § 2241 by judicially amending § 4042(d), see Aplt. Reply Br. at 4, 11. 5 Appellate Case: 25-1273 Document: 34-1 Date Filed: 07/16/2026 Page: 6
Thus, contrary to Davis’s argument, our reliance on § 4042(d)’s plain language does
not “produce a result demonstrably at odds with the intentions of its drafters.”
Griffin v. Oceanic Contractors, Inc., 458 U.S 564, 571 (1982).
Our conclusion that § 4042(d) is clear and unambiguous disposes of Davis’s
grammatical arguments and his contention that the statute is vague. It also disposes
of his reliance on the in pari materia canon of statutory construction and the rule of
lenity, both of which apply only when there is an ambiguity in a statute. See United
States v. McCarthy, 174 F.4th 1254, 1261 (10th Cir. 2026) (“It is a canon of
construction that statutes in pari materia should be construed together, so that
ambiguities in one statute may be resolved by looking at another statute on the same
subject.” (second emphasis added) (internal quotation marks omitted)); United States
v. Aguilar, 168 F.4th 1319, 1327 (10th Cir. 2026) (“If, after employing the usual
tools of statutory interpretation, we are left with a grievous ambiguity or uncertainty
concerning [a] statute, we employ the rule of lenity.” (emphasis added) (internal
quotation marks omitted)).
Davis’s one remaining argument meriting our attention is that by deferring to
the government’s reading of § 4042(d), the district court violated the teachings of
Loper Bright Enterprises v. Raimondo, 603 U.S. 369 (2024). We disagree.
In Loper Bright, the Supreme Court held that, under the Administrative
Procedures Act (“APA”), “‘the reviewing court’—not the agency whose action it
reviews—is to ‘decide all relevant questions of law’ and ‘interpret . . . statutory
provisions” without “mechanically afford[ing] binding deference to agency
6 Appellate Case: 25-1273 Document: 34-1 Date Filed: 07/16/2026 Page: 7
interpretations.” Id. at 398–99 (alteration in original) (emphasis omitted) (quoting
5 U.S.C. § 706). Assuming Loper Bright applies outside of the APA context and to
arguments a federal agency raises in a legal brief, we see no error here. The district
court did not afford binding deference to the government’s reading of § 4042(d) but
merely stated that it agreed with the government’s argument before performing its
own analysis of § 4042(d). That was an entirely permissible approach. See Loper
Bright, 603 U.S. at 403 (explaining that “Congress expects courts to do their ordinary
job of interpreting statutes, with due respect for the views of the Executive Branch.”)
III
We affirm the district court’s judgment. We grant Davis’s motion to proceed
on appeal without prepayment of costs or fees and remind him that he remains
obligated to pay the full amount of the filing fee. See 28 U.S.C. § 1915(a)(1)
(excusing only “prepayment of fees”).
