OPINION OF THE COURT
James Lyons appeals pro se from the District Court order denying his petition for a writ of habeas corpus. He claims that the Parole Commission improperly postponed his release date beyond the guideline range by relying on a 1987 amendment to the Sentencing Reform Act (“SRA”) that authorized upward departures but that such departures were not authorized when Lyons committed his crimes in 1986. Lyons argues that this 1987 amendment operates as an ex post facto law and is thеrefore unconstitutional as applied to him. We agree with Lyons’s ex post facto argument and therefore reverse.
I.
Lyons committed narcotics-trafficking and related firearm offenses in 1986. Soon thereafter, he was convicted and sentenced to an aggregate prison term of 40 *287 years. In 1996, after serving more than ten years of his sentence, Lyons had an initial parole hearing. The Parolе Commission determined that under the applicable guideline, Lyons would normally be eligible for parole after serving 100-148 months, i.e., no later than August 1998. However, the Commission determined that a parole eligibility date outside the guideline range was warranted because of Lyons’s “history of possessing/using weapons and violence.” (Exhibit 4 to the Response to Show Cause Order, filed in the District Court at Dkt. # 18). In postponing Lyons’s eligibility date, the Cоmmission apparently relied on 18 U.S.C. § 4206(c), which authorized the Commission to set release dates outside the guideline range for “good cause.” Finding good cause, the Commission continued Lyons’s incarceration until a mandatory release date in July 2009, more than ten years beyond the maximum term in his parole guideline range. The Commission reaffirmed its decision after a hearing in 1998.
In 1998, after serving 151 months of his prison term, Lyons filed a petition for a writ of habeas corpus in federal district court pursuant to 28 U.S.C. § 2241. He raised two challenges to the departure from his guideline range pursuant to the 1987 amendment: first, that application of this amendment violated the constitutional prohibition against ex post facto laws and, second, that it exceeded Congress’s authority under the separation-of-powers doctrine. The District Court rejected both his ex post facto and separation-of-powers arguments. It accordingly denied Lyons’s petition for habeas relief. This appeal followed.
II.
Lyons bases his claim to habeas relief primarily on the
ex post facto
clause of the United States Constitution.
1
See
U.S. Const. Art. 1, § 9 (“No ... ex post facto Law shall be passed.”). This clause forbids Congress from enacting any law “which imposes a punishment for an act which was not punishable at the time it was committed; or imposes
additional punishment
to that then prescribed.”
Weaver v. Graham,
As to the first element, the 1987 amendment to § 235(b)(3) is clearly retrospective. The parole transition sections to which § 235(b)(3) belongs apply to offenses committed
before
the SRA’s effective date.
See Tripati v. U.S. Parole Commission,
Lyons argues that the original § 235(b)(3) took effect upon enactment in 1984. The government argues that it did not take effect until November 1, 1987. If, as Lyons argues, the law in effect in 1986 was the original § 235(b)(3), requiring dates within the guideline range, then Lyons was clearly disadvantaged when the Commission relied on the 1987 amendment to postpone his release over ten years beyond the guideline’s maximum of 148 months. But if, as the government argues, the original § 235(b)(3) was not yet in effect when Lyons committed his crimes, then the Commission was still authorized to go outside the range. Thus, when the 1987 amendment simply restored that authority, Lyons’s punishment was no greater than when he committed his crimes, and therefore he was not “disadvantaged.”
We agree with Lyons that the original § 235(b)(3) took effect upon enactment and thus the 1987 amendment operated as an ex post facto law when it was applied to postpone his release date beyond his maximum guideline range of 148 months. We therefore find the amended § 235(b)(3) unconstitutional as applied to Lyons.
A.
Our analysis of the effective date begins with the text of the statute. The Sentenc
*289
ing Reform Act (“SRA”) was enacted as Chapter II of the multi-faceted Comprehensive Crime Control Act (“CCCA”). See Pub.L. 98-473, 98 Stat. 1837, 1987 (1984). The SRA’s purpose was to replace “a system of indeterminate sentences and the possibility of parole with determinate sentencing and nо parole.”
Walden v. U.S. Parole Commission,
B.
With this framework in mind, we turn to the interpretations of the courts. In this circuit, the contention that § 235(b)(3) took effect upon enactment of the SRA is a matter of first impression.

We have not yet faced a petitioner like Lyons: his release date hinges on our determination of when § 235(b)(3) went into effect, because he committed his crimes after the provision’s enactment in 1984 but before its amendment in 1987, and he was still in the Commission’s jurisdiction when the statute’s five-year transition period ended. The petitioner in
United States ex rel. D’Agostino v. Keohane,
We acknowledge that in
United States v. Martinez-Zayas,
Similarly, in another indirectly related matter — concerning the question whether the SRA also applies to offenses committed
before
its effective date — we noted that Congress amended § 235(a)(1) of the SRA to clarify that the SRA applies “only to offenses committed after” November 1, 1987.
Gallardo v. Quinlan,
C.
With no controlling precedent on point to guide us, we survey the decision of the other courts of appeals. Several of the courts of appeals have stated that § 235(b)(3) took effect on November 1, 1987. However, these statements were typically not grounded in analysis (referring instead to § 235(a), the SRA’s general effective-date provision) and rarely central to the holding.
See Evenstad v. United States,
We are aware of only two court of appeals cases, in the Ninth and Eleventh Cirсuits, in which the effective date of § 235(b)(3) was crucial to the holding.
7
See Evenstad v. United States,
In
Evenstad,
the petitioner argued that his guilty plea was involuntary becausе he had relied on the parole provisions of the original § 235(b)(3), which was later amended to his disadvantage. The Court stated, without analysis, that § 235(b)(3) did not take effect until November 1, 1987, and therefore held that the petitioner could not have relied on that provision when pleading guilty in 1986.
See Evenstad,
In
Coleman,
the petitioner argued that a release date within the guideline range was mandated by § 235(b)(3). The Court stated that § 235(b)(3) was meant solely as a “winding up” provision and was not meant to change the manner in which the Commission determined eligibility dates.
Coleman,
We are persuaded by the reasoning of the Second Circuit in
Romano
that § 235 took effect upon enactment in 1984.
See
the Chairman of the Parole Commission, who becomes an ex officio member of the Sentencing Commission by virtue of *292 subsection 235(b)(5), could not join the Sentencing Commission until November 1, 1987, almost six months after the Commission must submit its guidelines to Congress.
Id. at 839. 9 Certainly § 235(b)(5), although located within the SRA сhapter and not explicitly excepted from the uniform Effective Date, must be construed as taking effect upon enactment.
We agree that, absent a clear contrary intention in the text, “an effective date provision becomes effective the date of enactment.” Id. Seeing no clear contrary intention in the text, we hold that § 235(b)(3) took effect upon enactment on October 12, 1984. Therefore, this original provision — requiring the Commission to stay within the guideline range — was in effect when Lyons committed his crimes in 1986, and thus the retroactive application of the 1987 amendment to lengthen his punishment was unconstitutional under the ex post facto clause.
The District Court here, after noting that implicit repeals are disfavored, concluded that, under the reasoning in
Romano,
§ 235(b)(3) would have implicitly repealed 18 U.S.C. § 4206(c). We think that adopting the conclusion in
Romano
would work no such repeal. The Supreme Court recently reiterated its rule that “when two statutes are capable of coexistence, it is the duty of the courts, absent a clearly expressed congressional intention to the contrary, to regard each as effective.”
J.E.M. AG Supply, Inc. v. Pioneer Hi-Bred Int'l Inc.,
The District Court found that the statutory framework and legislative history supported its conclusion that § 235(b)(3) did not take effect until November 1, 1987. It viewed it as a winding-up provision, intended to ensure that the Parole Commission take action regarding those inmates who were sentenced under pre-SRA law and would still be in prison after the Commission was phased out. Because the Commission was to continue its business for five years after the SRA took effect, “there was no need for the § 235(b)(3) to go into effect before” the SRA’s effective date. App. at 31 (District Court’s Memorandum). The Senate Report did indicate an intent to distinguish between pre-SRA era and SRA-era offenses, to create a seamless phasing out of the Commission as the SRA took effect. The report stated that a “sentеnce imposed before the effective date of the [Sentencing] guidelines ... would not be affected by this title. As to an offense committed prior to the effective date, the preexisting law will apply as to all substantive matters including the imposable sentence.” S.Rep. No. 98-225, reprinted at 1984 U.S.C.C.A.N. 3182, 3372 (1985).
It may be true that, considering the mechanics of the transition, “there was no *293 need” for § 235(b)(3) to go into effect bеfore the rest of the SRA. It is also possible that Congress wished to design a transition without the window of opportunity through which Lyons sees his freedom. However, the text of the statute is the best expression of the intent of Congress. Using standard tools of statutory interpretation, we have carefully considered both the text and context of § 235(b)(3) and conclude that it took effect upon enactment.
III.
We hold that § 235(b)(3) took еffect on October 12, 1984, and, as originally enacted, applied to Lyons. Thus, he was a member of the class of individuals (who committed crimes between the enactment of the SRA in 1984 and the amendment of § 235(b)(3) in 1987) who are entitled to a parole release date within the guideline range. The application of the 1987 amendment to Lyons disadvantaged him because it permitted the Commission to set his release dаte beyond — rather than within — ■ the guideline range. By imposing additional, retrospective punishment on Lyons, the amended § 235(b)(3) operated as an ex post facto law. It is unconstitutional as applied to Lyons.
We will therefore reverse the District Court’s holding that § 235(b)(3) does not constitute an ex post facto violation against Lyons. We remand so that the District Court may issue the writ of habeas corpus.
Notes
. Lyons also invokes the separation-of-powers doctrine as an alternative basis for habeas relief. He argues that the 1987 amendment to § 235(b)(3) violates this doctrine because Congress lacks the authority to overrule two judicial decisions which Lyons believe support his claim,
Romano v. Luther,
Regardless of whether those two decisions are helpful to Lyons, his understanding and application of that doctrine are incorrect. The separation of powers doctrine provides, among other things, that Congress mаy not require federal courts to nullify or vacate their properly rendered final judgments.
See Plaut v. Spendthrift Farm, Inc,,
. Of course, to pursue an
ex post facto
challenge, Lyons must also show that § 235(b)(3) applied to him, i.e. that he was in the Parole Commission's jurisdiction the day before the expiration of the fivе-year period referred to in § 235(b)(3).
See supra,
note 3. Courts have consistently held that the start date of the five-year period referred to in § 235(b)(3) was November 1, 1987.
See Lightsey v. Kastner,
*288 Because Lyons had not been released on parole, we find that he was clearly still in the Parole Commission's jurisdiction when the five-year period ended on the day before November 1, 1992.
.Section 235(b)(3), as originally enacted in 1984 as part of the SRA, provided:
The United States Parole Commission shall set a release date, for an individual who will be in its jurisdiction the day before the expiration of five years after the effective date of this Act, that is within the range that applies to the prisoner under the applicable parole guideline. A release date set pursuant to this paragraph shall be set early enough to permit consideration of an appeal of the release date, in accordance with Parole Commission procedures, before the expiration of five years following the effective date of this Act.
Pub.L. 98-473, 98 Slat. 2032 (1984) (prior to 1987 amendment) (emphasis added).
. Before enactment of the SRA, the Parole Commission was permitted to go beyond the guideline range in those cases with "good cause for so doing.” 18 U.S.C. § 4206(c) (1982).
. The amended version of § 235(b)(3), enacted on December 7, 1987, instructed the Commission to set a release date "pursuant to • Section 4206 of Title 18 United States Code,” and deleted the words, "that is within the range that applies to the prisoner under the applicable parole guideline.” See Sentencing Act of 1987, § 2, Pub.L. 100-182, 101 Slat. 1266 (1987). Once again, upward departures from the guideline range were authorized for “good cause.” 18 U.S.C. § 4206.
. In
Madonna v. U.S. Parole Commission,
. A number of cases have denied relief to petitioners seeking to challenge the timing of their release based on the 1987 amendment to § 235(b)(3). However, with one exception, these petitioners are factually distinguishable from Lyons.
In some cases, the petitioner was sentenced before the SRA was enacted. Thus, the petitioner was sentenced under 18 U.S.C. § 4206 that authorized the Commission to set release dates
outside
of the guideline range for good cause. The 1987 amendment to § 235(b)(3) merely restored that authority. Thus, those petitioners would not be disadvantaged by the amendment and could not satisfy the test for an
ex post facto
challenge.

871 F.2d
1560,
1563 (11th Cir.1989);
Norwood,
In other cases, the petitioner was scheduled to be released
before
the end of the five-year period specified in § 235(b)(3), and the provision did not apply on its face.
Miller,
In still other cases, the petitioner was disqualified for relief for both of these reasons.
See Tripati
v.
United States Parole Commission,
In one Ninth Circuit case,
United States v. Silver,
. Like Lyons, the petitioners in these two cases committed offenses
after
the SRA was enacted but before § 235(b)(3) was amended in 1987. Although there is no discussion of the fact in either case, it appears that each petitioner would have been in the Parole Commission's jurisdiction at the end of the five-year period referred to in § 235(b)(3).
See Evenstad,
. The
Romano
court nevertheless held that the petitioner was not eligible for belief under § 235(b)(3), because he would not be within the Commission's jurisdiction on November 1, 1992.
