ORDER

Everyone now agrees that the district court exceeded the statutory maximum when it tacked on a term of five, instead of three, years supervised release to Robert Perry’s 180 month prison sentence. Perry tried to correct the sentencing error six years after the judgment in his case became final by filing a Motion to Correct Clerical Error under Rule 36 of the Federal Rules of Criminal Procedure. The district court correctly determined that Rule 36 did not apply and denied Perry’s motion because the error was not clerical in nature as this court has interpreted the rule. See United States v. Lawrence, 535 F.3d 631 (7th Cir. 2008).

This does not leave Perry without a means to correct the district court’s mistake. A motion under 28 U.S.C. § 2255 permits a district court to correct a sentencing mistake such as the one in this ease. See United States v. Boyd, 591 F.3d 953, 956 (7th Cir. 2010) (§ 2255 can be used to challenge a sentence and not just the conviction that underlies it). And, contrary to the district court’s observation, relief under § 2255 is available if the government waives the one year limitations defense contained in 28 U.S.C. § 2255(f), permitting the district court to correct its sentencing error. See Wood v. Milyard, — U.S. -, 132 S.Ct. 1826, 182 L.Ed.2d 733 (2012). This seems likely in view of its concession that Perry is correct and the term of supervised release for Perry’s crimes should have been limited to three years.

But as to the matter now before us, the district court’s Order denying Perry’s Rule 36 motion is AFFIRMED.
