OPINION
Dеfendant, Gerald Garrett, appeals his conviction for possession of a stolen vehicle, a second degree felony, in violation of Utah Code Ann. § 41-1-112 (Supp.1991). We affirm.
BACKGROUND
On June 29, 1991, Gerald and Josephine Hood reported to the police that their white 1980 Cadillac with Texas license platеs was missing. That same day, but before the report was made, a police officer was patrolling the west side of Salt Lake City. *579 As he passed Pioneer Park, he noticed a white Cadillac with Texas license plates that looked out of place for the area. The car was parked and “fully occupied.” The officer observed that the person in the driver's seat had marks on his face and a bandaged hand. Shortly after the officer left the area, he heard a dispatcher’s broadcast about the missing car. He immediately returned to the park.
When the officer arrived, other officers were already present and taking people out of the car. The officer saw defendant about forty yards away from the car and recognized him as the person who was previously seated in the driver’s seat. The officer questioned defendant about the car. Defеndant stated that the car belonged to Gerald Hood who had been arrested, and that he was going to bail Gerald Hood out of jail. When the officer asked who had the car keys, defendant indicated that they were in his front pocket. The officer removed the keys from defendant’s pockеt. Defendant then handed the officer the car registration from his shirt pocket. Mr. Hood was summoned to the park. He told the officer that he did not recognize defendant and that he had not been arrested. Mr. Hood also identified the keys.
Defendant testified at trial that he and others, including “Jerry,” had gone to a grocery store earlier that morning to get some food and beer. According to defendant, when the group returned to the park Jerry gave defendant the keys to turn on the car radio and get some beer from the trunk. Defendant further testified that when the police arrived, Jerry told defendant to watch the car because Jerry “might have a warrant.” Jerry then left the park.
Defendant also claimed at trial that he did not remember having the car registration in his shirt pocket. Finally, he denied telling the police that Gerald Hood was in jail and that he was trying to bail him out.
The jury found defendant guilty. On apрeal, defendant claims that he was denied effective assistance of counsel because his counsel proposed, and the trial court used, an erroneous jury instruction explaining reasonable doubt. He also claims that his counsel was ineffective in failing to challenge the prоsecutor’s use of peremptory strikes to remove the only three racial minorities from the jury panel. Finally, defendant claims that the evidence was insufficient to sustain his conviction.
ANALYSIS
I. Ineffective Assistance
In order to bring a successful ineffective assistance of counsel claim pursuant to the Sixth Amendment,
1
a defendant must show that trial counsel’s performance was deficient in that it “fell below an objective standard of reasonableness,” and that the deficient performance prejudiced the outcome of the trial.
Strickland v. Washington,
When a defendant claims that trial counsel’s performance was deficient, wе must “indulge in the strong presumption that counsel’s conduct falls within the wide range of reasonable professional assistance; that is, the defendant must overcome the presumption that under the circumstances, the challenged action ‘might be considered sound trial strategy.’ ”
Strickland,
In order to demonstrate that trial counsel’s deficient performance prejudiced the defendant, “[t]he defendant must show that there is a reasonable probability that, but for counsel’s unprofessional errors, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome.”
Strickland,
In addition to the substantive requirements discussed above, there is a threshold requirement that must be met before we may consider an ineffective assistance of counsel claim on dirеct appeal. Ordinarily, such a claim may only be raised through a collateral attack in habeas corpus proceedings because “the trial record is insufficient to allow the claim to be determined” on direct appeal.
State v. Humphries,
A. Jury Instruction
Defendant asserts that the reasonable doubt instruction presented by his defense counsel was erroneous in that it did not adequately convey the concept of reasonable doubt as described in
State v. Johnson,
We elect to address the prejudice prong of
Strickland
since it is determinative of this claim. The defendant has not proven prejudice, as is his affirmative duty.
See Strickland,
Inasmuch as it is unlikely that defendant would have enjoyed a more favorable result in the absence of the purported errors in the instruction, the alleged errors do nоt undermine our confidence in the outcome. We therefore hold that defendant was not prejudiced by counsel’s reasonable doubt *581 instruction. Consequently, his claim regarding the jury instruction fails.
B. Batson Challenge
Defendant also claims that his trial counsel was deficient in failing to object to the prosecution’s use оf its peremptory challenges in a manner that he now claims may have been racially motivated.
See generally Batson v. Kentucky,
We do not know from the record before us whether the prosecution in fact had race-neutral reasons for removing the potential jurors because defense counsel did not object. Nor do we know for certain whether defense counsel’s failure to object to the strikes was deficient performance or trial strategy. Defense counsel may have had the apparent language problem in mind in not objeсting to the prosecution’s removal of the two potential jurors. It is also conceivable that perceptions of inattentiveness or a lack of sympathy towards defendant — or any myriad of intangible factors — could prompt competent defense counsel to forgo asserting а Batson challenge. Given the presumption that defense counsel was acting properly, we must assume that defense counsel also wanted these potential jurors removed and therefore did not raise a Batson challenge as a matter of strategy. Any evidence to the contrary is simply not in the rеcord before us. The record is therefore inadequate for us to find on direct appeal that counsel’s performance was objectively deficient.
Defendant has requested that we remand this claim for an evidentiary hearing if we do not reverse his conviction outright. Under new rule 23B of thе Utah Rules of Appellate Procedure, we may remand claims of ineffective assistance of counsel for an evidentiary hearing. Defendant has not, however, complied with the formalities of rule 23B. The rule requires a defendant to file a motion requesting remand before oral arguments аre made. We have not received any such motion. More importantly, the rule also requires the movant to submit affidavits “alleging facts not fully appearing in the record on appeal that show the claimed deficient performance of the attorney. The affidavits shall also allegе facts that show the claimed prejudice suffered by the appellant as a result of the claimed deficient performance.” Utah R.App.P. 23B(b). We have not received any such affidavits in this case.
Rule 23B allows us to remand a claim of ineffective assistance at any time under our own motiоn, even if the technical formalities of the rule discussed above have not been complied with. Our discretion to remand is limited, however, in that the claim must have been made
and
“the motion would have been available to a party.” Utah R.App.P. 23B(a). We conclude that in this case the motion would not have been available to defendant. Subparagraph (a) of rule 23B expressly provides that
“[t]he motion shall be available only upon an allegation of facts
constituting ineffective assistance of counsel not fully appearing in the record.” (Emphasis added.) Defendant has not alleged any facts that would establish trial counsel’s deficient performance or the prejudice suffered by defendant. At best, defendant has simply speculated that trial counsel’s failure to object might not have been due to trial strategy. Given the rule’s clear emphasis on specific factual allegations, it would be improper to remand a claim under rule 23B for a fishing expedition. Not only would a remand based on speculation be inconsistent with the presumption of sound trial strategy, it would likely open a floodgate of incomplete
*582
and fragmented ineffective assistancе claims on direct appeal. Because defendant has not alleged any facts in support of his ineffective assistance claim, we do not remand it for an evidentiary hearing.
See State v. McNicol,
Based оn the record before us, and the strong presumption of sufficient performance, we reject defendant’s contention that his counsel’s performance was objectively deficient. His ineffective assistance claim therefore fails on direct appeal.
II. Insufficient Evidence
Defendant claims that the evidence is insufficient to support his conviction. This court has limited authority to review a jury verdict when a sufficiency of the evidence claim is raised.
State v. Boone,
CONCLUSION
Any error made in the reasоnable doubt instruction presented by defendant’s trial counsel did not prejudice the outcome of his case. The record is inadequate to allow us to find on direct appeal that trial counsel’s failure to object to the prosecution’s striking of the only minority members of the jury pool was оbjectively deficient performance. Furthermore, we decline to remand this matter sua sponte under rule 23B because defendant has not made specific allegations establishing trial counsel’s deficient performance or the prejudice he suffered because of it. Finally, the еvidence in this case is sufficient to support defendant’s conviction.
We therefore affirm the conviction.
BILLINGS and ORME, JJ., concur.
Notes
. The Sixth Amendment to the United States Constitution provides in part: “In all criminal prosecutions, the accused shall enjoy the right to ... have Assistance of counsel for his defense." This right to assistance has been held to be “the right to effective assistance of counsel.”
McMann v. Richardson,
. Inasmuch as the deficient performance prong and the prejudice prong must both be satisfied, we may address whichever issue will most readily resolve the claim.
Strickland,
. An additional requirement to hearing an ineffective assistance claim on direct appeаl is that the defendant must be represented by new counsel on appeal because it is "unreasonable to expect [trial counsel] to raise the issue of his own ineffectiveness at trial on direct appeal.”
