Defendant Alfred Lee O’Neil appeals from three convictions of unlawful distribution of a controlled substance, first degree felonies in violation of Utah Code Ann. § 58-37-8(l)(a), (b) (Supp.1992). Defendant asserts the trial court erred in admitting evidence of his prior conviction. We affirm.
FACTS
Defendant and his wife were charged with three counts of unlawful distribution of methamphetamine. A confidential informant working for the State purchased methamphetamine from defendant’s wife on December 6, 10, and 12, 1990. The State alleged defendant knew of the drug sales because he drove his wife to the bar where the transactions occurred. Further, defendant was present in the bar during two of the transactions. Defendant’s criminal liability was based on an accomplice theory under Utah Code Ann. § 76-2-202 (1990).
Judge Halliday presided over a joint trial of defendant and his wife. On the first day of trial, counsel for the couplе filed a motion and supporting memoranda asking that the State be prevented from introducing evidence about the prior convictions, crimes, wrongs or acts of defendant or his wife. The disputed evidence involved defendant’s 1987 conviction for distribution of cocaine. He had received a 1 to 15 year sentence and was paroled in September of 1990. In conjunction with the 1987 incident, his wife pled guilty to a charge of attempted distribution. She had been placed on probation. The State did not file a response to defendant’s motion. The judge granted the motion. The jury convicted defendant’s wife but could not reach a decision on defendant. Judge Halliday declared a mistrial as to defendant.
Judge Bunnell presided over a subsequent hearing to determine whether to schedule a second trial or dismiss the charges against defendant. At the hearing, thе State asked for a ruling on a motion to allow evidence of defendant’s prior conviction. After reviewing memo-randa in support and opposition, Judge Bunnell granted the motion. At the ensuing trial defendant was convicted.
On appeal, defendant claims the doctrine of “law of the case” precluded Judge Bunnell from reconsidering Judge Halliday’s ruling on the admissibility of defendant’s prior conviction. Defendant also claims thе admission of the prior conviction evidence was reversible error. 1
I. LAW OF THE CASE
Defendant argues that Judge Halliday’s ruling, which denied the admissibility of his *697 prior conviction, was the “law of the case” and, therefore, Judge Bunnell was precluded from allowing the evidence at his second trial. The State responds that the law of the case doctrine is not applicable.
Law of the case is a legal doctrine courts apply when refusing to readdress an issue previously decided in the same case.
See Plumb v. State,
The doctrine of law of the case has two branches. The first branch requires an issue decided by an appellate court “ ‘be followed in all subsequent proceedings in the same case ... unless ... the decision was clearly erroneous and would work a manifest injustice.’ ”
Conder v. A.L. Williams & Assocs.,
Utah courts have not considered the impact of a mistrial on the doctrine of law of the case. Other jurisdictions, faced with conflicting evidentiary rulings in sequential trials have concluded that the doctrine of law of the case is inapplicable.
In
State v. Commeau,
*698 [T]he law of the case doctrinе does not apply when a mistrial has been declared in a proceeding in which a determination was made on the admissibility of prior convictions.... [T]he declaration of a mistrial renders the trial itself a nullity and returns both parties to their original positions, as if there had been no trial.
Id.
A New Jersey appeals court reached the same conclusion in
State v. Hale,
was not the “law of the case” binding on the court when the same issue was raised at the second trial. The declaration of mistrial rendered nugatory all of the proceedings during the first trial. The State and defendant were returned to their original positions as if there had not been a trial. Each was entitled to offer evidence and to make motions and objections without limitation to that which had been offered or made at the first trial, and without being bound by the prior rulings of the court with respect thereto. If the result were otherwise, the evidentiary problems on a retrial would be insurmountable and the administration of justice rendered completely unworkable.
Id. at 734.
We agree a second trial after a mistrial is not the same case for purposes of the law of the case. Accordingly, defendant’s reliance on the law of the case doctrine to prevent the admission of his prior conviction at the second trial is misplaced.
II. ADMISSION OF THE PRIOR CONVICTION
Defendant also contends that the trial court erred as a matter of law when it allowed evidence of his prior conviction at his second trial. The State responds the evidence was proрerly admitted to show knowledge on the part of defendant. Prior to the second trial, Judge Bunnell ruled evidence of defendant’s and his wife’s prior convictions admissible. 3 During trial, the judge considered and also allowed, under Rule 404(b) and Rule 403, testimony which showed that in February of 1992, defendant had attempted to collect a drug debt owed to his wife by the State’s confidential informant. 4
Defendant argues that evidence of his prior conviction was inadmissible under Rule 404(b) and Rule 403 of the Utah Rules of Evidence. Because the admission of evidence under Rule 404(b) is a question “of law, it is reviewed for correctness. However, the trial court’s subsidiary factual determinations should be given deference by the appellate court and only be
*699
overruled when they are clearly erroneous.”
State v. Taylor,
Thus, the procedure this cоurt follows when reviewing the admission of prior bad act evidence is straight-forward. First, the evidence must, as a matter of law, be admissible under Rule 404(b). Second, we determine, as a matter of law, whether the trial court acted reasonably in striking the probative value versus prejudicial effect balance required by Rule 403. If both those standards are met we will affirm. If we determine either of the first two standards is not met, we must then determine whether the аdmission of the evidence amounted to prejudicial error.
A. Rule 404(b)
We first examine whether the evidence of defendant’s prior conviction was admissible under Rule 404(b). Rule 404(b) provides:
Evidence of other crimes, wrongs or acts is not admissible to prove the character of a person in order to show that he acted in conformity therewith. It may, however, be admissible for other purposes, such, as proof of motive, oppоrtu *700 nity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident.
Utah R.Evid. 404(b).
In
State v. Taylor,
Utah appellate courts have often admitted evidence of other crimes, wrongs or acts pursuant to Rule 404(b).
See, e.g., State v. Shickles,
A recent federal case,
United States v. Martino,
Thus, Rule 404 allows prior bad act evidence in a criminal trial where it is offered to show any element оf the alleged crime. Prior bad act evidence is only excluded where the sole reason it is being offered is to prove bad character or to show that a person acted in conformity with that character.
Essential elements of the distribution offense are that defendant acted with knowledge and intent. See Utah Code Ann. § 58-37-8(l)(a) (Supp.1992). The trial court specifically found that the defendant’s prior convictions and “their surrounding circumstanсes are probative of the knowledge, intent, plan and scheme” regarding the charges. We agree. Defen *701 dant claims that although he was present he “knew nothing.” This places his knowledge and intent in issue. Thus, like the prosecution in Martino, the State was entitled to offer this prior conviction evidence as probative of defendant’s knowledge and intent in this drug transaction. Therefore, the trial court did not err in admitting evidence of defеndant’s prior conviction under Rule 404(b).
B. Rule 403
Even though the evidence regarding defendant’s prior conviction is admissible under Rule 404(b), it must also meet the requirements of Rule 403.
See State v. Shickles,
Utah appellate courts have outlined several factors to be considered when a court balances the probativeness of evidence against its prejudicial effect. These factors include
“the strength of the evidence as to the commission of the other crime, the similarities between the crimes, the interval of time that has elapsed between the crimes, the need for the evidеnce, the efficacy of alternative proof, and the degree to which the evidence probably will rouse the jury to overmastering hostility.”
Shickles,
Applying the
Shickles
analysis here, we conclude the trial court acted well within the limits of reasonability in allowing the evidence of defendant’s earlier conviction. A documented conviction is the strongest possible evidence of a prior crime. The earlier crime was also for distribution of a small amount of a controlled substance, thus the crimes are similar. The three years between the earliеr conviction and the events leading to the defendant’s arrest is a short period of time, especially considering defendant spent a significant portion of that time incarcerated. Although the State had other evidence of knowledge and intent from witnesses, that evidence was clearly not effective based on the first trial. Furthermore, the evidence is not barred simply because the State had some other evidеnce of intent.
See Shickles,
The trial court considered the evidence and reasonably concluded the probative value of the convictions was not outweighed by the danger of unfair prejudice. Thus, the trial court appropriately admitted the evidence pursuant to Rule 403. 7
CONCLUSION
Because evidentiary rulings made prior to a mistrial аre not the law of the case in a re-trial, defendant has no claim of error based on the admission of his prior conviction at his second trial following its exclusion at his first trial. Additionally, the evidence of defendant’s prior conviction was properly admitted at his second trial under Rule 404(b) and Rule 403. Thus, we affirm defendant’s convictions.
Notes
. Defendant also asserts that the change in judges was somehow improper. This argument is without merit. The Utah Code of Judicial Administration Rule 3-104(3)(E)(ii) gives the presiding judge the authority to manage the court’s docket. See Utah C.Jud.Admin. 3-104(3)(E)(ii). Defendant has no right to a particular judge. He only has the right to an impartial judge. Rule 29(c) of the Utah Rules of Criminal Procedure provides the method for a defendant to challenge the impartiality of a judge. That rule requires defendant file an affidavit alleging bias or prejudice. See Utah R.Crim.P. 29(c). There is no allegation or evidence thаt Judge Bunnell was anything but completely impartial.
. There are a number of situations in which it is proper for a court to exercise its discretion and review an issue previously decided by a co-equal court. Reconsideration is appropriate when the matter is presented in a "different light" or under “different circumstances.”
See Sittner v. Big Horn Tar Sands & Oil, Inc.,
Because we affirm on different grounds, we need not decide whether the facts of this case fit one of these situations. We note, however, because dеfendant’s wife was no longer involved at the second trial, any prejudice to her was no longer an issue concerning the admission of defendant’s prior bad acts. Further, admission of defendant’s prior bad acts was not fully addressed in the first trial.
. Although far from clear, defendant apparently attempts to challenge the admission of his wife’s conviction under Rule 404(b). We note that admission of her conviction standing alone would not be an issuе governed by Rule 404(b). It would instead be considered under Rule 402 and Rule 403. To the extent their convictions are intertwined and her conviction is utilized as evidence of defendant’s other bad acts, the analysis for admission of her conviction under Rule 404(b) is substantially indistinguishable from that used for his conviction. Thus, we consider only the admission of defendant’s conviction.
. The defendant’s only references to this “dunning" incident are a mention of the evidence coming in at trial and a discussion of the harmful effect of bad act evidence generally. He does not argue the admission of this later incident was improper under any rule. Thus, we do not consider it separately on appeal. We note, however, a number of courts have discussed the issue of subsequent act evidence finding it admissible under Rule 404(b).
See, e.g., State v. Bibo-Rodriguez,
. The standard of review under Rule 403, as articulated by the Utah Supreme Court, has seen an evolution over the past few years. Although recently clarified by the supreme court in State v. Thurman, the following discussion is perhaps helpful in understanding the standard of review.
In
State v. Johnson,
The court clarified the standard, however, in
State v. Hamilton,
“[i]n reviewing a trial court’s ruling on the admissibility of evidence, under rule 403, we will not overturn the court’s determination unless it was an "abuse of discretion.” See [State v.] Verde, 770 P.2d [116,] 120 [(Utah 1989) ]. To state the matter more precisely, we review the trial court’s 403 ruling admitting or denying admission to evidence by deciding whether, as a matter of law, the trial court’s decision that 'the unfairly prejudicial potential of the evidence outweighs [or does not outweigh] its probativeness’ was beyond the limits of reasonability.”
Id.
at 239-40 (quoting
Ramirez,
The supreme court recently reaffirmed the
Hamilton
definition of "abuse of discretion.” In a case analyzing the standard of review for Rule 11 sаnctions,
Barnard v. Sutliff,
Thus, instead of rejecting abuse of discretion as the appropriate standard of review for the admission of evidence under Rule 403 as the court appeared to do in
Ramirez,
the court has simply defined the term to mean a review of the reasonableness of the trial court. A trial court that acts unreasonably has committed a legal error. Therefore, when reviewing a trial court’s decision to admit evidence under Rule 403, we assess whether, as a matter of law, the trial court acted reasonably in striking the balance.
See State v. Thurman,
. Utah courts look "to the interpretations of the federal rules [of evidence] by the federal courts to aid in interpreting the Utah rules.”
State v. Banner,
. Defendant attempts to make some arguments based on Rule 609. That rule addresses the propriety of admitting prior bad act evidence for impeachment purposes. See Utah R.Evid. 609. The trial judge admitted the evidence under Rule 404(b) and Rule 403 and we affirm. Hence, we do not consider whether the evidence was admissible under Rule 609.
