Argued and Submitted August 14, 2025
San Francisco, California
Before: RAWLINSON and KOH, Circuit Judges, and FITZWATER, District
Judge.**
The United States (the Government) appeals the district court’s grant of the
motion for compassionate release filed by Juan Ramon Matta-Lopez (Matta-
Lopez). Matta-Lopez was convicted for conduct that occurred before the
enactment of the Sentencing Reform Act (SRA) on November 1, 1987. Under the
pre-SRA statutory scheme, 18 U.S.C. § 4205(g) (the old law), Matta-Lopez is
precluded from personally moving for compassionate release.1 Defendants
sentenced under the post-SRA framework, 18 U.S.C. § 3582(c) (the new law), may
personally move for compassionate release. See Matta-Ballesteros, 843 F. App’x
at 893. The district court determined that this discrepancy in the availability of an
inmate’s ability to move for compassionate release constituted a violation of
Matta-Lopez’s “Fifth Amendment right to equal protection of the laws.” We
disagree and reverse.

Any motion for compassionate release under the old law must be filed by
the Bureau of Prisons (BOP). See United States v. Matta-Ballesteros, Nos. 20-
50129, 20-50130, 843 F. App’x 892, 893 (9th Cir. Feb. 12, 2021) (unpublished).

within its jurisdiction the equal protection of the laws.” Olson v. California, 104
F.4th 66, 76 (9th Cir. 2024) (en banc) (citations, alteration, and internal quotation
marks omitted). Rational basis review applies because no suspect classifications or
fundamental rights are implicated. See id. “Under this standard, [a statutory
scheme] carries with it a presumption of rationality, and we must uphold it if the
legislative means are rationally related to a legitimate governmental purpose.” Id.
at 76–77 (citation and internal quotation marks omitted). “To establish an Equal
Protection claim, [Matta-Lopez] must demonstrate that a class that is similarly
situated has been treated disparately.” Id. at 77 (citation and internal quotation
marks omitted). “The comparator groups need not be similar in all respects, but
they must be similar in those respects relevant to the . . . policy.” Id. (citation and
internal quotation marks omitted). Once comparator groups are identified, Matta-
Lopez “must . . . negate every conceivable basis which might support such
disparate treatment.” Id. (citations and internal quotation marks omitted).
Matta-Lopez argues that inmates serving life without the possibility of
parole sentences under the old law are similarly situated to inmates serving life
sentences without parole under the new law.2 Assuming, without deciding, that
these groups are similarly situated, Matta-Lopez’s claim fails because the laws he

Under the new law, parole was abolished. Thus, no inmate under the new
law may seek parole. See Mistretta v. United States, 488 U.S. 361, 367 (1989).
3 25-3402
challenges are rationally based.
Matta-Lopez argues that, as applied to him, the statutes are unconstitutional
because there is no rational basis for prospectively allowing inmates to personally
move for compassionate release, while not allowing a similar path to early release
for inmates sentenced under the old law. However, this argument is foreclosed by
our precedent. See United States v. Navarro, 800 F.3d 1104, 1114 (9th Cir. 2015)
(noting that simply because Congress’s “reasoning will apply with greater force to
some groups of inmates than to others does not invalidate its otherwise-valid
decision”).
Matta-Lopez has “not met his burden to negat[e] every conceivable basis
which might support [Congress’s] decision to [make the SRA prospective].” Id.
(citation and internal quotation marks omitted). The SRA overhauled the
indeterminate sentencing model and revised the sentencing process to reflect
Congress’s desire to reduce disparity in sentencing and “the uncertainty as to the
time the offender would spend in prison.” Mistretta, 488 U.S. at 366. The fact that
the resulting sentencing scheme left inmates sentenced under the old law without
the ability to personally move for compassionate release does not render the
scheme irrational. See Navarro, 800 F.3d at 1114 (noting that “[a] classification
does not fail rational-basis review because it is not made with mathematical nicety
or because in practice it results in some inequality”) (citation omitted).
4 25-3402
Congress acted within its authority in determining that the SRA would apply
prospectively. See Jones v. Cupp, 452 F.2d 1091, 1093 (9th Cir. 1971) (per
curiam). We have long held that “[t]here is noting unconstitutional in a
legislature’s conferring a benefit on prisoners only prospectively.” Id. (citation
omitted). The provisions of the SRA do not deny Matta-Lopez equal protection
under the Fifth Amendment. See Navarro, 800 F.3d at 1114.3
REVERSED.

Because our determination that there is no Fifth Amendment violation
resolves this case, we need not and do not address the merits of Matta-Lopez’s
motion for compassionate release. See United States v. King, 24 F.4th 1226, 1232
(9th Cir. 2022).
