Petitioner-appellee James F. Johnson is an inmate in federal custody serving an aggregate U.S.Code and District of Columbia (D.C.) Code sentence. In district court, Johnson filed a habeas petition, pursuant to 28 U.S.C. § 2241, arguing that he was entitled to credit under his D.C. sentence for “street time” accrued prior to revocation of his parole. The district court agreed and granted the requested relief. On appeal by respondents-appellants Thomas Kindt and the U.S. Parole Commission (the Commission), we reverse the judgment of the district court and remand for further proceedings consistent with this opinion. 1
BACKGROUND
Johnson was convicted of the D.C. crimes of rape and carrying a pistol without a license and also the federal crime of possession of cocaine with intent to distribute. In 1985, the United States Bureau of Prisons calculated his aggregated sentence at approximately twenty-five years (thirteen years under the D.C.Code and twelve years under the U.S.Code). On February 4, 1989, the Commission reléased Johnson on parole with approximately twenty-one years left to be served. 2
*1062 On August 24, 1994, the Commission issued an arrest warrant for a parole violation (commission of new criminal conduct). As of that date, Johnson had accumulated approximately five and one-half years of street time, 3 allocated proportionately to the federal and D.C. crimes as 910 days to the U.S.Code sentence and 1092 days to the D.C.Code sentence. The Commission revoked Johnson’s parole and ordered the forfeiture of his street time.
Johnson filed a habeas petition, arguing that, under D.C.Code § 24&emdash;431(a), a provision effective April 11, 1987, he should have retained credit for the 1092 days of street time attributable to his D.C. sentence.

The Commission, however, asserted that a previous, and conflicting, D.C.Code provision required the forfeiture of D.C. street time upon the revocation of parole.
See
D.C.Code § 24-206(a) (providing that, after revocation of parole, “[t]he time a prisoner was on parole shall not be taken into account to diminish the time for which he was sentenced”). The district court, relying on the case of
Noble v. United States Parole Commission,
The Commission appealed the district court’s ruling to this court. While the appeal was pending, the Court of Appeals for the District of Columbia resolved the statutory interpretation issue by answering a question certified by the United States Court of Appeals for the District of Columbia in the
Noble
case.

It determined that D.C.Code § 24-431(a) does not effect an implied repeal of D.C.Code § 24-206(a), so that once parole is revoked, D.C. law does not entitle an offender to street-time credit.
See United States Parole Comm’n v. Noble,
On appeal, Johnson concedes that this court is bound by the
Noble III
holding,
see Johnson v. Fankell,
DISCUSSION
Generally, “[a] judicial construction of a statute is an authoritative statement of what the statute meant before as well as after the decision of the case giving rise to that construction.”
Rivers v. Roadway Express, Inc.,
an unforeseeable judicial enlargement of a criminal statute, applied retroactively, operates precisely like an ex post facto law, such as Art. I, § 10 of the Constitution forbids.... If a state legislature is barred by the Ex Post Facto Clause from passing such a law, it must follow that a State Supreme Court is barred by the Due Pro *1063 cess Clause from achieving precisely the same result by judicial construction.
Bouie v. City of Columbia,
The test for determining whether the retroactive application of a judicial decision violates due process is essentially one of foreseeability.
See McDonald v. Champion,
A judicial construction
of
a statute is unforeseeable if it is “unexpected and indefensible by reference to the law which had been expressed prior to the conduct at issue."
Bouie,
The case of
Tyler v. United States,
Federal prison officials, however, reached a different conclusion. The Commission determined that § 24-206(a), the street time forfeiture statute, was still valid, and continued to apply it. See id. at 455-57.
After weighing the merits of the divergent positions taken by the D.C. government and the Commission, the
Tyler
court concluded that § 24^131(a) “did not impliedly repeal the longstanding requirement of section 24-206 that parole violators forfeit their street time.”
Id.
at 457. Until the decision in
Noble III
was announced,
Tyler
was the only appellate decision that directly addressed the issue.
See Noble III,
In 1994, when Johnson violated his parole, it was foreseeable that the Commission’s view would ultimately prevail. The
Noble III
decision did not expand a narrow and precise legislative provision or overrule controlling precedent. Moreover, elementary legal research would have revealed the principle that repeals by implication are disfavored.
See, e.g., Crawford Fitting Co. v. J.T. Gibbons, Inc., 482
U.S. 437, 442,
The judgment of the United States District Court for the Western District of Oklahoma *1064 is REVERSED and REMANDED with instructions to deny Johnson’s request for ha-beas relief.
Notes
. After examining the briefs and appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal. See Fed. R.App. P. 34(a); 10th Cir. R. 34.1.9. The case is therefore ordered submitted without oral argument.
. The Commission, which has statutory authority to make parole decisions for D.C. offenders
*1062
housed in federal prisons, is required to follow D.C. law with regard to D.C. offenses.
See Johnson v. Williford,
. " 'Street time’ is measured from the date of release on parole to the execution or the [arrest] warrant or confinement on other charges." 28 C.F.R. § 2.66(i).
. D.C.Code § 24-431(a) provides:
Every person shall be given credit on the maximum and the minimum term of imprisonment for time spent in custody or on parole as a result of the offense for which the sentence was imposed. When entering the final order in any case, the court shall provide that the person be given credit for the time spent in custody or on parole as a result of the offense for which sentence was imposed.
.The certified question was:
Under District of Columbia law ..., did the United States Parole Commission properly interpret sections 24-206(a) and 24-431(a) of the District of Columbia Code in deciding that, after revocation of a person’s parole, time that the person spent on parole before revocation cannot be credited against his sentence?
Noble v. United States Parole Comm’n,
. Wc note that the D.C. Court of Appeals has expressed no view on “whether there should be any limitation on the class of prisoners the ruling should reach; i.e., the issue of retroactivity/pros-pectivity.’’ Noble III, 693 A.2d at 1104.
