Opinion by
11 A jury found defendant, Christopher Douglas Wise, guilty of several offenses, including two felonies, arising out of his theft of a car and subsequent robbery and assault of an elderly woman. The district court adjudicated him a habitual eriminal and subsequently imposed lengthy prison sentences which, as relevant here, included consecutive forty-eight year terms on the felony convie-tions.
12 In People v. Wise, (Colo.App. No. 10CA0832,
T3 The supreme court granted the People's petition, vacated the division's decision, and remanded the case to this court "for reconsideration in light of People v. Novotny, 10SC377, 2014 CO ¶ 18." In Novoiny, the court abrogated the automatic reversal rule on which the prior division had relied, holding that reversal is required for a district court's deprivation of a defendant's peremp-, tory challenge only where the error was not "harmless under the proper outcome-determinative test."
14 On remand to this court, defendant filed a motion arguing that applying the holding of Novotny to this case would be an unconstitutionally retrospective application of the law, and, alternatively, that he should be allowed an opportunity to present evidence and argument in the district court so that the district court can determine whether the error was harmless. The People opposed that motion, and defendant subsequently filed a reply in support. This court ordered the motion deferred to the merits division, and ordered the parties to submit supplemental briefs addressing whether, under the existing record, the district court's error was harmless.
15 Having considered the parties' original briefs, their supplemental briefs, defendant's motion, the People's response thereto, and defendant's reply, we hold as follows: (1) we must apply Novotny 's holding to this case on the existing record, and may do so without violating defendant's right to due process; (2) remanding the case to the district court for an evidentiary hearing and findings is not warranted; (8) the district court's error resulting in defendant's loss of a peremptory challenge was harmless because defendant has not shown that a biased or incompetent juror participated in deciding his guilt; and (4) the district court did not abuse its discretion in imposing consecutive sentences.» Because the prior division rejected defendant's other contentions of error, we accordingly affirm the judgment and sentence.
I. Denial of Challenge for Cause
T6 The district court denied defendant's challenge for cause to prospective juror K. Defendant used one of his peremptory challenges to exeuse prospective juror K and eventually used all of his peremptory challenges. On appeal, defendant contended that the district court abused its discretion in denying his challenge to prospective juror K, but he did not assert any other error with respect to the composition of the jury. The prior division held that the district court had erred in denying the challenge for cause to prospective juror K, and we assume that the district court erred for purposes of our analysis. *
A. We Must Apply Novotny
T7 Defendant contends in his motion and supplemental brief that applying the holding of Novotny to this case would violate his right to due process because he did not have fair warning of Novotny 's change in the law. We reject this contention, for two reasons.
18 First, we are bound by the "mandate rule" to apply the holding of No-votny. That rule requires that we follow the supreme court's mandate. See In re Marriage of Balanson,
110 Second, in any event, we perceive no due process problem with applying the holding of Novotny to this case. We note initially that it is questionable whether the premise of defendant's due process argument-that applying the holding of Novotny to this case would be a retroactive application of a change in the law-is correct.
111 The holding in Novotny does not affect the process for challenging prospective jurors for cause, the standards applicable to the determination of any such challenge, or any matter relevant to the use of peremptory challenges. Nor does it make criminal that which was not, alter any burden of proof, affect the admissibility or weight of evidence, or enhance a defendant's punishment. See Novotny, 1 25 ("As a remedy for error rather than a rule involving duties or defenses, or defining error itself, the automatic reversal rule ... can be abandoned with little concern that by doing so we will unfairly upset settled expectations around which the behavior of defendants has been justifiably ordered."). In short, it has no legal effect on proceedings in the district court, including both the determination of guilt and punishment. Rather, it changes only the framework for determining whether the appellate court must reverse a conviction because a defendant used a peremptory challenge to excuse a juror whom the defendant had unsuccessfully challenged for cause. Applying it here would not apply it to a prior appeal, but to a pending appeal as to which the appellate remedy is not yet final.
¶ 12 Nonetheless, assuming that a retroactive application of a change in the law would result from applying the holding of Novotny to this case, we conclude that defendant's right to due process would not thereby be violated.
T13 A contention that a judicial decision improperly operates retroactively "must be analyzed under the Due Process Clause and 'in accordance with the more basic and general principle of fair warning.' " People v. LaRosa,
¶ 14 The automatic reversal rule was not definitively adopted in Colorado until the supreme court's decision in People v. Macrander,
¶ 15 LaRosa, 2013 CO ¶ 2,
116 Had the supreme court in LaRosa applied its holding to the case before it, the result would have been to uphold a conviction on the basis of evidence that, at the time of trial, was insufficient as a matter of law under controlling case law. As discussed above, there would be no such effect in this case if the holding of Novotny is applied. And as also discussed above, the rule abrogated by Novotny did not enjoy the widespread acceptance and consistent history of application in Colorado that the rule at issue in LaRosa did.
B. Remand to the District Court is Not Warranted
€17 We also deny defendant's alternative request that we remand the case to the district court for an evidentiary hearing and determination of harmlessness. Nothing in Novotny or the supreme court's mandate in this case indicates that such a remand would be necessary or appropriate. And defendant does not explain what such a hearing would entail. As discussed, Novotny has no legal effect on district court procedure or indeed on challenges for cause or peremptory challenges. We are therefore not persuaded that an evidentiary hearing could shed light on whether defendant was tried before a fair and impartial jury-which is, after all, the right protected by both challenges for cause and peremptory challenges. See Martinez-Salazar,
¶ 18 Nor are we persuaded that such a hearing could shed light on whether defendant was otherwise harmed by the use of a peremptory challenge to exeuse prospective juror K. To the extent defendant would attempt to make a record challenging for cause any juror who actually served, we observe that defendant has already waived any such challenge. See Crim. P. 24(b)(@Q) ("All matters pertaining to the qualifications and competency of the prospective jurors shall be deemed waived by the parties if not raised prior to the swearing in of the jury to try the case. ..."); People v. Lewis,
119 Because Novotny affects only the framework for determining the remedy for an alleged error, we conclude that the assessment must be based on the existing record. This court routinely reviews contentions of error under outcome-determinative tests, and we fail to see why the error here would not lend itself to such an assessment.
120 Therefore, we ideny defendant's motion and proceed to apply Novotny 's holding to the facts of this case.
C. The Error Does Not Require Reversal
21 In Novotny, the court instructed that "an appropriate case specific, outcome-determinative analysis" must be applied when determining whether the error requires reversal. Novotny, T27. Read in context, it is clear that the court was referring to an assessment under a harmless error test. See id. at 1118-21, 28. But the court did not make explicit which harmless error test-ordinary harmless error or constitutional harmless error-should be applied.
122 There are two ways of looking at it. If the error is viewed as the erroneous denial of a challenge for cause, the constitutional harmless error test-under which the People must show that the error was harmless beyond a reasonable doubt, see Hagos v. People,
123 But if the "error" is viewed as the deprivation of a peremptory challenge, the ordinary harmless error test would seem to apply. This is because the right to use peremptory challenges is purely statutory; it is not derived from the Constitution. See Ross,
1124 We conclude that the latter approach is correct, for three reasons. First, where, as here, a defendant used a peremptory challenge to excuse a prospective juror whom the defendant had unsuccessfully challenged for cause, any "error" in the denial of the challenge for cause was "cured"-the prospective juror who should have been excused was excused. See Ross,
1 25 Second, in Novotny, the court appears to have regarded the error at issue in a case such as this as the deprivation of a peremptory challenge. See Novotny, I 14 (referring to the "erroneous ruling on a challenge for cause adversely impacting the defendafit’s
11 26 And third, courts in other jurisdictions that recognize an impairment in this context and that have rejected the automatic reversal rule have applied the ordinary harmless error test, reasoning that only the noneonstitu-tional right to exercise peremptory challenges is at issue. See, eg., Dailey v. State,
127 We therefore apply the ordinary harmless error test. Under that test we must disregard any error that does not affect a party's substantial rights. Crim. P. 52(a); Novotny, 120. This requires us to evaluate "the likelihood that the outcome of the proceedings in question were affected by the error." Novotny, 120. The defendant must "establish a reasonable probability that the error contributed to the verdict." Krutsinger v. People,
128 In the specific situation that confronts us, the court in Novotny made clear that the mere loss of a peremptory challenge, standing alone, is insufficient to require reversal.. Novotny, 127. Courts in other jurisdictions have held that to make a showing of prejudice sufficient to require reversal in this context, the defendant ordinarily must show that a biased or incompetent juror participated in deciding his guilt. See, e.g., Minch v. State,
129 Defendant has not shown that a biased or incompetent juror participated in deciding his guilt.
130 We acknowledge that in most (perhaps close to all) cases, a defendant will be unable to show such prejudice as a result of using a peremptory challenge to excuse a prospective juror who should have been excused for cause. But we do not view that difficulty as an indication that there is some inherent harm which is difficult to precisely identify or quantify. Rather, we view it as an indication that no cognizable harm inheres in these cireumstances. See United States v. Patterson,
131 The law is concerned with the impairment of at least "substantial rights,"
II. Consecutive Sentences
32 In the opinion issued before remand, the prior division addressed all of defendant's contentions except his contention that the district court abused its discretion in imposing consecutive sentences for his two felony convictions. We address that contention now, and reject it.
133 Where, as here, a defendant's multiple convictions are not based on identical evidence, the district court has discretion to impose either concurrent or consecutive sentences. Juhl v. People,
134 Deféndant contends that the district court imposed consecutive sentences "without any explanation other than generally to reference 'the cireumstances' of the case and to note that the offenses were separate The record, however, criminal episodes." does not bear that out.
¶ 35 At the sentencing hearing, the court said, in determining that habitual sentencing was appropriate, that it had considered "the evidence presented at the trial and the information contained in the presentence investigation report."
186 Thus, considered in context, the court's later reference to the "circumstances of the case," in imposing consecutive sentences, can reasonably be understood as a reference to the circumstances to which it had earlier referred. We are not willing to conclude that the court ignored the considerations to which it had referred only moments earlier. Instead, we conclude that the court's remarks, considered as a whole, constitute a sufficient explanation of the basis for its decision to impose consecutive sentences.
IIL Conclusion
187 For the foregoing reasons, and those expressed in the prior division's opinion, the judgment and sentence are affirmed.
Taubman and Ney
Notes
. See People v. Macrander,
. It may be that the Novotny holding will have some practical effect in some cases on how defendants use challenges for cause and peremptory challenges. But any such effect would not implicate constitutional or statutory rights; it would pertain instead only to strategy. Indeed, defendant does not explain how the Novotny decision impairs a defendant's ability to participate in ensuring a fair and impartial jury.
. Indeed, the division's original disposition of this case included a concurrence by Judge Russel criticizing the automatic reversal rule. The author of the division's original majority decision also had criticized the rule in a prior unpublished decision.
. We also observe that the defendant in Novotny filed a petition for rehearing raising the same due process argument defendant raises in this case. The supreme court denied that petition.
. Under federal law, a defendant's use of a peremptory challenge to excuse a potential juror as to whom the court erroneously denied a challenge for cause is not even deemed an impairment of the right to exercise peremptory challenges. United States v. Martinez-Salazar,
. Some courts have also suggested that prejudice may be shown where a court repeatedly and deliberately denies meritorious challenges for cause so as to force the defendant to use his peremptory challenges, see, e.g., Martinez-Salazar,
. In his supplemental brief, defendant concedes that "[this record does not show whether there was further prejudice or partiality on the remaining venire. '.."
. The presentence investigation report discussed the facts of the offenses of which defendant was convicted, defendant's extensive criminal history, the fact he had "done poorly on prior periods of supervision," defendant's life history, defendant's education, and his refusal to accept responsibility for his conduct. It opined that defendant presents "a very high risk to the community."
