delivered the opinion of the Court.
In this case we review a decision of the Court of Appeals for the Eleventh Circuit holding that the commentary to the *38 Sentencing Guidelines is not binding on the federal courts. We decide that commentary in the Guidelines Manual that interprets or explains a guideline is authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.
Petitioner Terry Lynn Stinson entered a plea of guilty to a five-count indictment resulting from his robbery of a Florida bank. The presentence report recommended that petitioner be sentenced as a career offender under the Sentencing Guidelines. See United States Sentencing Commission, Guidelines Manual §4B1.1 (Nov. 1989). Section 4B1.1 provided that a defendant is a career offender if:
“(1) the defendant was at least eighteen years old at the time of the instant offense, (2) the instant offense of conviction is a felony that is either a crime of violence or a controlled substance offense, and (3) the defendant has at least two prior felony convictions of either a crime of violence or a controlled substance offense.”
All concede that petitioner was at least 18 years old when the events leading to the indictment occurred and that he then had at least two prior felony convictions for crimes of violence, thereby satisfying the first and third elements in the definition of career offender. It is the second element in this definition, the requirement that the predicate offense be a crime of violence, that gave rise to the ultimate problem in this case. At the time of his sentencing, the Guidelines defined “crime of violence” as, among other things, “any offense under federal or state law punishable by imprisonment for a term exceeding one year that... involves conduct that presents a serious potential risk of physical injury to another.” §4B1.2(1). The United States District Court for the Middle District of Florida found that petitioner’s conviction for the offense of possession of a firearm by a convicted felon, 18 U. S. C. § 922(g), was a crime of violence, satisfying the second element of the career offender definition. Al *39 though the indictment contained other counts, the District Court relied only upon the felon-in-possession offense in applying the career offender provision of the Guidelines. In accord with its conclusions, the District Court sentenced petitioner as a career offender.
On appeal, petitioner maintained his position that the offense relied upon by the District Court was not a crime of violence under USSG §§4B1.1 and 4B1.2(1). The Court of Appeals affirmed, holding that possession of a firearm by a felon was, as a categorical matter, a crime of violence.
Rather than considering whether the amendment should be given retroactive application, the Court of Appeals held that commentary to the Guidelines, though “persuasive,” is of only “limited authority” and not “binding” on the federal courts.
Id.,
at 815. It rested this conclusion on the fact
*40
that Congress does not review amendments to the commentary under 28 U. S. C. § 994(p). The Court of Appeals “decline[d] to be bound by the change in section 4B1.2’s commentary until Congress amends section 4B1.2,s language to exclude specifically the possession of a firearm by a felon as a ‘crime of violence.”’
The Sentencing Reform Act of 1984 (Sentencing Reform Act), as amended, 18 U. S. C. §3551
et seq.
(1988 ed. and Supp. Ill), 28 U.S.C. §§991-998 (1988 ed. and Supp. Ill), created the Sentencing Commission, 28 U. S. C. § 991(a), and charged it with the task of “establish[ingj sentencing policies
*41
and practices for the Federal criminal justice system,” § 991(b)(1). See
Mistretta
v.
United States,
*42
As we have observed, “the Guidelines bind judges and courts in the exercise of their uncontested responsibility to pass sentence in criminal cases.”
Mistretta
v.
United States, supra,
at 391. See also
Burns
v.
United States,
In the case before us, the Court of Appeals determined that these principles do not apply to commentary.
It does not follow that commentary is binding in all instances. If, for example, commentary and the guideline it interprets are inconsistent in that following one will result in violating the dictates of the other, the Sentencing Reform Act itself commands compliance with the guideline. See 18 U. S. C. §§ 3553(a)(4), (b). Some courts have refused to follow commentary in situations falling short of such flat inconsistency. Thus, we articulate the standard that governs the decision whether particular interpretive or explanatory commentary is binding.
Different analogies have been suggested as helpful characterizations of the legal force of commentary. Some we reject. We do not think it helpful to treat commentary as a contemporaneous statement of intent by the drafters or issuers of the guideline, having a status similar to that of, for example, legislative committee reports or the advisory committee notes to the various federal rules of procedure and evidence. Quite apart from the usual difficulties of attributing meaning to a statutory or regulatory command by refer *44 ence to what other documents say about its proposers’ initial intent, here, as is often true, the commentary was issued well after the guideline it interprets had been promulgated. The guidelines of the Sentencing Commission, moreover, cannot become effective until after the 6-month review period for congressional modification or disapproval. It seems inconsistent with this process for the Commission to announce some statement of initial intent well after the review process has expired. To be sure, much commentary has been issued at the same time as the guideline it interprets. But neither the Guidelines Manual nor the Sentencing Reform Act indicates that the weight accorded to, or the function of, commentary differs depending on whether it represents a contemporaneous or ex post interpretation.
We also find inapposite an analogy to an agency’s construction of a federal statute that it administers. Under
Chevron U. S. A. Inc.
v.
Natural Resources Defense Council, Inc.,
Although the analogy is not precise because Congress has a role in promulgating the guidelines, we think the Government is correct in suggesting that the commentary be treated as an agency’s interpretation of its own legislative rule. Brief for United States 13-16. The Sentencing Commission promulgates the guidelines by virtue of an express congressional delegation of authority for rulemaking, see
*45
Mistretta
v.
United States,
According this measure of controlling authority to the commentary is consistent with the role the Sentencing Reform Act contemplates for the Sentencing Commission. The Commission, after all, drafts the guidelines as well as the commentary interpreting them, so we can presume that the interpretations of the guidelines contained in the commentary represent the most accurate indications of how the Commission deems that the guidelines should be applied to be consistent with the Guidelines Manual as a whole as well as the authorizing statute. The Commission has the statutory obligation “periodically [to] review and revise” the guidelines in light of its consultation with authorities on and representatives of the federal criminal justice system. See 28 U. S. C. § 994(b). The Commission also must “revie[w] the presentence report, the guideline worksheets, the tribunal’s
*46
sentencing statement, and any written plea agreement,”
Mistretta
v.
United States, supra,
at 369-370, with respect to every federal criminal sentence. See 28 U. S. C. § 994(w). In assigning these functions to the Commission, “Congress necessarily contemplated that the Commission would periodically review the work of the courts, and would make whatever clarifying revisions to the Guidelines conflicting judicial decisions might suggest.”
Braxton
v.
United States,
It is perhaps ironic that the Sentencing Commission’s own commentary fails to recognize the full significance of interpretive and explanatory commentary. The commentary to the Guideline on commentary provides:
“[I]n seeking to understand the meaning of the guidelines courts likely will look to the commentary for guidance as an indication of the intent of those who wrote them. In such instances, the courts will treat the commentary mueh like legislative history or other legal material that helps determine the intent of a drafter.” USSG § 1B1.7, comment.
We note that this discussion is phrased in predictive terms. To the extent that this commentary has prescriptive content, we think its exposition of the role of interpretive and explanatory commentary is inconsistent with the uses to which the Commission in practice has put such commentary and the
*47 command in.§lB1.7 that failure to follow interpretive and explanatory commentary could result in reversible error.
We now apply these principles to Amendment 433. We recognize that the exclusion of the felon-in-possession offense from the definition of “crime of violence” may not be compelled by the guideline text. Nonetheless, Amendment 433 does not run afoul of the Constitution or a federal statute, and it is not “plainly erroneous or inconsistent” with §4B1.2, Bowles v. Seminole Rock & Sand Co., supra, at 414. As a result, the commentary is a binding interpretation of the phrase “crime of violence.” Federal courts may not use the felon-in-possession offense as the predicate crime of violence for purposes of imposing the career offender provision of USSG §4B1.1 as to those defendants to whom Amendment 433 applies.
The Government agrees that the Court of Appeals erred in concluding that commentary is not binding on the federal courts and in ruling that Amendment 433 is not of controlling weight. See Brief for United States 11-19. It suggests, however, that we should affirm the judgment on an alternative ground. It argues that petitioner’s sentence conformed with the Guidelines Manual in effect when he was sentenced, id., at 22-29, and that the sentence may not be reversed on appeal based upon a postsentence amendment to the provisions in the Manual, id., at 19-22. The Government claims that petitioner’s only recourse is to file a motion in District Court for resentencing, pursuant to 18 U. S. C. § 3582(e)(2). Brief for United States 33-35. It notes that after the Court of Appeals denied rehearing in this case, the Sentencing Commission amended USSG § 1B1.10(d), p. s., to indicate that Amendment 433 may be given retroactive effect under § 3582(c)(2). See Amendment 469, USSG App. C, p. 296 (Nov. 1992).
We decline to address this argument. In refusing to upset petitioner’s sentence, the Court of Appeals did not consider
*48
the nonretroactivity theory here advanced by the Government; its refusal to vacate the sentence was based only on its view that commentary did not bind it. This issue, moreover, is not “fairly included” in the question we formulated in the grant of certiorari, see
The judgment of the United States Court of Appeals for the Eleventh Circuit is vacated, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
Notes
Amendment 433 was contrary to a substantial body of Circuit precedent holding that the felon-in-possession offense constituted a crime of violence in at least some circumstances. See,
