437 F.3d 1103
UNITED STATES of America, Plaintiff-Appellee,v.Sylena BRITT, Defendant-Appellant.
No. 04-10151 Non-Argument Calendar.
United States Court of Appeals, Eleventh Circuit.
January 26, 2006.

Brenda G. Bryn, Fed. Pub. Def., Fort Lauderdale, FL, Lori E. Barrist, Fed. Pub. Def., West Palm Beach, FL, Kathleen M. Williams, Fed. Pub. Def., Miami, FL, for Britt.
Karlyn J. Hunter, Anne R. Schultz and Lisette M. Reid, Asst. U.S. Attys., Miami, FL, for U.S.
Appeal from the United States District Court for the Southern District of Florida.
ON REMAND FROM THE SUPREME COURT OF THE UNITED STATES
Before BLACK, CARNES and HULL, Circuit Judges.
PER CURIAM:


1
This case is before the Court for consideration in light of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We previously affirmed Britt's sentence. United States v. Britt, 388 F.3d 1369 (11th Cir.2004). The Supreme Court vacated our prior decision and remanded the case to us for further consideration in light of Booker.


2
In her initial brief on direct appeal, Britt did not assert error based on Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), or any other case extending or applying the Apprendi principle. In her reply brief, Britt asserted for the first time that the application of a U.S.S.G. § 3B1.3 enhancement for an abuse of a position of trust was unconstitutional under Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004). Because Britt did not raise the Blakely argument in her initial brief, the Government filed a motion to strike the issue from the reply brief. We granted the Government's motion. Alternatively, Britt requested leave to file a supplemental brief addressing Blakely. We denied Britt's motion to file a supplemental brief. After we affirmed Britt's sentence, Britt filed a petition for rehearing in which she once again argued that her sentence violated Apprendi, Blakely, and the Fifth and Sixth Amendments of the Constitution. We denied her petition for rehearing.


3
In United States v. Levy, 416 F.3d 1273, 1275-76 (11th Cir.), cert. denied, ___ U.S. ___, 126 S.Ct. 643, ___ L.Ed.2d ___ (2005), we summarized our prudential rule of declining to consider issues not timely raised in a party's initial brief.


4
Parties must submit all issues on appeal in their initial briefs. When new authority arises after a brief is filed, this circuit permits parties to submit supplemental authority on "intervening decisions or new developments" regarding issues already properly raised in the initial briefs. Also, parties can seek permission of the court to file supplemental briefs on this new authority. But parties cannot properly raise new issues at supplemental briefing, even if the issues arise based on the intervening decisions or new developments cited in the supplemental authority.


5
Id. (quoting United States v. Nealy, 232 F.3d 825, 830 (11th Cir.2000)). We expressly stated that we decline "to consider issues raised for the first time in an appellant's reply brief," and that we "repeatedly ha[ve] denied motions to file supplemental briefs that seek to raise new issues not covered in an appellant's initial brief on appeal." Id. at 1276 n. 3 (citations omitted).


6
Because Britt did not assert error based on Apprendi (or its progeny) in her initial brief on appeal and raised the issue for the first time in her reply brief, we reinstate our previous opinion in this case and affirm Britt's sentence after our reconsideration in light of Booker, pursuant to the Supreme Court's mandate.


7
OPINION REINSTATED IN PART; AFFIRMED IN PART.
