Per Curiam.
Clyde Timothy Bunkley petitions for a writ of certiorari, arguing that the Florida Supreme Court contradicted the principles of this Courts decision in Fiore v. White, 531 U.S. 225 (2001) (per curiam), when it failed to determine whether the common pocketknife exception to Floridas definition of a

In the early morning hours of April 16, 1986, Bunkley burglarized a closed, unoccupied Western Sizzlin Restaurant. Report and Recommendation in No. 91113CIVT
99(B) (MD Fla.), p. 1. The police arrested him after he left the restaurant. At the time of his arrest, the police discovered a pocketknife, with a blade of 21
Bunkley was charged with burglary in the first degree because he was armed with a dangerous weapon
namely, the pocketknife. Fla. Stat. §810.02(2)(b) (2000). The punishment for burglary in the first degree is imprisonment for a term of years not exceeding life imprisonment. §810.02(2). If the pocketknife had not been classified as a dangerous weapon, Bunkley would have been charged with burglary in the third degree. See 833 So. 2d 739, 742 (Fla. 2002). Burglary in the third degree is punishable by a term of imprisonment not exceeding 5 years. Fla. Stat. §775.082(3)(d) (2002); see also 833 So. 2d, at 742. Bunkley was convicted of burglary in the first degree. He was sentenced to life imprisonment. In 1989, a Florida appellate court affirmed Bunkleys conviction and sentence. See 539 So. 2d 477.
Florida law defines a
In 1997, the Florida Supreme Court interpreted the meaning of the common pocketknife exception for the first time. In L. B. v. State, 700 So. 2d 370, 373 (per curiam), the court determined that a pocketknife with a blade of 33
After the Florida Supreme Court issued its decision in L. B., Bunkley filed a motion for postconviction relief under Florida Rule of Criminal Procedure 3.850 (1999). Bunkley alleged that under the L. B. decision, his pocketknife could not have been considered a weapon under §790.001(13). He therefore argued that his conviction for armed burglary was invalid and should be vacated because a common pocketknife can not [sic] support a conviction involving possession of a weapon. App. to Pet. for Cert. C2. The Circuit Court rejected Bunkleys motion, and the District Court of Appeal of Florida, Second District, affirmed. 768 So. 2d 510.
The Florida Supreme Court also rejected Bunkleys claim. It held that the L. B. decision did not apply retroactively. Under Florida law, only jurisprudential upheavals will be applied retroactively. 833 So. 2d, at 743 (internal quotation marks omitted). The court stated that a jurisprudential upheaval is a major constitutional change of law. Id., at 745 (internal quotation marks omitted). By contrast, any evolutionary refinements in the law are not applied retroactively. Id., at 744. The court then held that L. B. was an evolutionary refinement in the law, and therefore Bunkley was not entitled to relief. In a footnote, the Florida Supreme Court cited our decision in Fiore v. White, supra, and held without analysis that Fiore did not apply to this case. See 833 So. 2d, at 744, n. 12.*
Justice Pariente, joined by Chief Justice Anstead, dissented. She stated that the Florida Supreme Courts decision in L. B. should be applied to grant Bunkley collateral relief. 833 So. 2d, at 746. She criticized the majority opinion for relying solely on a retroactivity question. In her view, application of the due process principles of Fiore renders a retroactivity analysis unnecessary. Id., at 747. She noted that even if L. B. was merely an evolutionary refinement of the law, the majority offers no precedent laying out the stages of this evolution. 833 So. 2d, at 747. Because she thought the L. B. decision correctly stated the law at the time Bunkleys conviction became final, she would have vacated Bunkleys conviction. 833 So. 2d, at 747.
II
Fiore v. White involved a Pennsylvania criminal statute that the Pennsylvania Supreme Court interpreted for the first time after the defendant Fiores conviction became final. See 531 U.S., at 226. Under the Pennsylvania Supreme Courts interpretation of the criminal statute, Fiore could not have been guilty of the crime for which he was convicted. See id., at 227228. We originally granted certiorari in Fiore to consider when, or whether, the Federal Due Process Clause requires a State to apply a new interpretation of a state criminal statute retroactively to cases on collateral review. Id., at 226. Because we were uncertain whether the Pennsylvania Supreme Courts decision
represented a change in the law, we certified a question to the Pennsylvania Supreme Court. Id., at 228. This question asked whether the Pennsylvania Supreme Courts interpretation of the statute
When the Pennsylvania Supreme Court replied that the ruling
made clear that Fiores conduct did not violate an element of the statute, his conviction did not satisfy the strictures of the Due Process Clause. Consequently, retroactivity [was] not at issue. Id., at 226.
Fiore controls the result here. As Justice Pariente stated in dissent, application of the due process principles of Fiore may render a retroactivity analysis unnecessary. 833 So. 2d, at 747. The question here is not just one of retroactivity. Rather, as Fiore holds, retroactivity is not at issue if the Florida Supreme Courts interpretation of the common pocketknife exception in L. B. is a correct statement of the law when [Bunkleys] conviction became final. 531 U.S., at 226. The proper question under Fiore is not whether the law has changed. Rather, Fiore requires that the Florida Supreme Court answer whether, in light of L. B., Bunkleys pocketknife of 21
Although the Florida Supreme Court has determined that the L. B. decision was merely an evolutionary refinement in the meaning of the common pocketknife exception, it has not answered whether the law in 1989 defined Bunkleys 21
It is true that the Florida Supreme Court held Fiore inapplicable because the L. B. decision was a change in the law which culminat[ed] [the] century-long evolutionary process. 833 So. 2d, at 745. As the dissent acknowledges, however, see post, at 12, n. 1, the Florida Supreme Courts decision in L. B. cast doubt on the validity of Bunkleys conviction. For the first time, the Florida Supreme Court interpreted the common pocketknife exception, and its interpretation covered the weapon Bunkley possessed at the time of his offense. In the face of such doubt, Fiore entitles Bunkley to a determination as to whether L. B. correctly stated the common pocketknife exception at the time he was convicted. Ordinarily, the Florida Supreme Courts holding that L. B. constitutes a change inrather than a clarification ofthe law would be sufficient to dispose of the Fiore question. By holding that a change in the law occurred, the Florida Supreme Court would thereby likewise have signaled that the common pocketknife exception was narrower at the time Bunkley was convicted.
Here, however, the Florida Supreme Court said more.
It characterized L. B. as part of the century-long evolutionary process. 833 So. 2d, at 745. Because Florida law was in a state of evolution over the course of these many years, we do not know what stage in the evolutionary process the law had reached at the time Bunkley was convicted. The Florida Supreme Court never asked whether the weapons statute had evolved by 1989 to such an extent that Bunkleys 21
On remand, the Florida Supreme Court should consider whether, in light of the L. B. decision, Bunkleys pocketknife of 21
It is so ordered.
*. The dissent claims that the Florida Supreme Court did not need to decide anything other than whether L. B. was a change in the law. See post, at 3 (citing Fla. Rule Crim. Proc. 3.850(b)(2) (2000)). Yet as the dissent concedes, see post, at 12, the Florida Supreme Court passed upon the Fiore due process inquiry as well as the retroactivity question. The dissent also notes that Bunkley has raised the issue of the common pocketknife in prior appeals. These appeals, however, were filed prior to the Florida Supreme Courts opinion in L. B. And we agree with the dissent that absent the L. B. decision, Bunkley would not be able to pursue his claim now. The Florida Supreme Court committed an error of law here by not addressing whether the L. B. decision means that at the time Bunkley was convicted, he was convicted of a crimearmed burglaryfor which he may not be guilty. Therefore, Michigan v. Long, 463 U.S. 1032 (1983), has no applicability here.
