    UNITED STATES of America, Plaintiff-Appellee, v. Darrell WEST, Defendant-Appellant.
    No. 04-30275.
    United States Court of Appeals, Fifth Circuit.
    Decided April 6, 2006.
    Cristina Walker, Assistant U.S. Attorney, U.S. Attorney’s Office Western District of Louisiana, Shreveport, LA, for Plaintiff-Appellee.
    
      Rebecca L. Hudsmith, Federal Public Defender, Federal Public Defender’s Office, Western District of Louisiana, Lafayette, LA, for Defendant-Appellant.
    Before REAVLEY, DAVIS, and WIENER Circuit Judges.
   ON REMAND FROM THE UNITED STATES SUPREME COURT

PER CURIAM:

This matter is before us on remand from the United States Supreme Court for reconsideration in light of its recent opinion in United States v. Booker. At our request, the parties have submitted supplemental letter briefs addressing the impact of Booker. For the following reasons, we find that Booker does not affect Defendant-Appellant Darrell West’s sentence.

I. BACKGROUND

West pleaded guilty to conspiring to distribute 50 grams or more of cocaine base, distributing 50 grams or more of cocaine base, and possessing with the intent to distribute 50 grams of cocaine base. The district court sentenced West to 292 months of imprisonment. West appealed his sentence, and we affirmed in an unpublished opinion. West then appealed his sentence to the United States Supreme Court, which, as noted above, remanded to us for reconsideration in light of Booker.

II. DISCUSSION

A. Standard of Review

West raised his Booker claims for the first time on appeal. Therefore, we review for plain error. This means that we will not remand for resentencing unless there is “(1) error, (2) that is plain, and (3) that affects substantial rights.” If the circumstances meet all three criteria, we may exercise our discretion to notice the error, but only if it “seriously affects the fairness, integrity, or public reputation of judicial proceedings.”

Since Booker, sentencing under mandatory Guidelines constitutes (1) error, and that error is (2) plain. Whether the error affects substantial rights is a more complex inquiry in which the defendant bears the burden of proof, and he carries his burden if he can “demonstrate a probability ‘sufficient to undermine confidence in the outcome.’ ” The defendant demonstrates such a probability when he identifies from the record an indication that the sentencing judge would have reached a significantly different result under an advisory Guidelines scheme.

B. Mlerits

West concedes that he cannot meet his burden to show plain error under Mares. Instead, West presents three alternative arguments. First, he urges the court to reconsider Mares. Mares, however, is the settled law of this circuit, and we can revisit it only en banc or following a Supreme Court decision that effectively overturns it. Second, West argues that Booker error is structural, and that we should therefore remand for resentencing on that ground. This circuit, however, has determined that Booker error is not structural. Finally, West insists that Booker error should be presumed prejudicial. Again, this circuit has determined that Booker error should not be presumed prejudicial. West presents no viable ground for remand. Accordingly, we affirm his original sentence.

III. CONCLUSION

As the district court did not commit plain error, West’s sentence is

AFFIRMED. 
      
       Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
