UNITED STATES OF AMERICA,

	Plaintiff-Appellee,

v.

ROBERT ALLEN CUSTARD,

	Defendant-Appellant.	No. 05-1454
(D.C. No. 93-CR-50-ZLW)
(Colorado)	

ORDER AND JUDGMENT*

Before MURPHY, SEYMOUR, and McCONNELL, Circuit Judges.

	Robert Allen Custard, a federal prisoner proceeding pro se, appeals from the district court’s recharacterization of his filing entitled “Defendant’s Motion For Reduction of Sentence Pursuant To 18 U.S.C [§] 3582” as a motion to vacate, set aside or correct his sentence pursuant to 28 U.S.C. § 2255, which it thereafter denied as untimely.  We affirm the district court’s determination that it lacked authority to act on Mr. Custard’s requests made pursuant to § 3582, but vacate its recharacterization of the action as a § 2255 motion.
	On July 12, 2004, Mr. Custard filed his “Motion For Reduction of Sentence Pursuant To 18 U.S.C [§] 3582,” in which he argued the United States Supreme Court’s holding in Blakely v. Washington, 542 U.S. 296 (2004), required a review of his sentence.  The district court determined it was without authority to consider Mr. Custard’s request under § 3582, but then construed the filing as a § 2255 motion and dismissed it as time barred.  Mr. Custard filed a “Motion for Recission [sic] Of the July 28, 2005 Order And/Or Notice of Appeal Of the July 28, 2005 Order,” arguing the district court could not recharacterize his § 3582 motion as a § 2255 motion without first providing him notice of the “adverse consequences” of such a recharacterization and permitting him the opportunity to withdraw or amend his action.  The district court denied his request to rescind the order.  Before us, Mr. Custard renews his objection to the district court’s recharacterization of his action.	
	The district court correctly concluded it could not modify Mr. Custard’s sentence pursuant to § 3582 as he requested.  “A district court is authorized to modify a Defendant’s sentence only in specified instances where Congress has expressly granted the court jurisdiction to do so.”  United States v. Blackwell, 81 F.3d 945, 947 (10th Cir. 1996) (citations omitted).  “Section 3582(c) provides that a court may not modify a term of imprisonment once it has been imposed except in three limited circumstances.”  United States v. Smartt, 129 F.3d 539, 540-41 (10th Cir. 1997) (emphasis in the original; citations and internal quotation marks omitted).  None of those circumstances is present here.  Accordingly, the district court was without jurisdiction to consider Mr. Custard’s request for a modification of his sentence.  See id. at 541.
	The district court erred, however, in recharacterizing Mr. Custard’s filing as a § 2255 motion without first notifying him of the consequences and providing him an opportunity to withdraw or amend his claims.  In Castro v. United States, the United States Supreme Court held that a 
district court must notify [a] pro se litigant that it intends to recharacterize [his] pleading, warn the litigant that this recharacterization means any subsequent § 2255 motion will be subject to restrictions on ‘second or successive’ motions, and provide the litigant an opportunity to withdraw the motion or to amend it so that it contains all the § 2255 claims he believes he has.
 
540 U.S. 375, 383 (2003).  Because the district court failed to comply with the Supreme Court’s holding in Castro, we conclude its recharacterization of Mr. Custard’s filing was improper.  The district court erred by denying Mr. Custard an opportunity to amend or withdraw his action. 
	Accordingly, we VACATE the court’s recharacterization of Mr. Custard’s action as a § 2255 motion, but we AFFIRM its dismissal of Mr. Custard’s § 3582 action.
