OPINION
Petitioners in this case were each arrested and subsequently convicted for driving while intoxicated (DWI). Petitioners each made motions to suppress the results of breathalyzer tests administered to them on the ground that the police failed to preserve a breath sample. Their cases were stayed in the district court pending the outcome of a case before the court of appeals raising the same issue.
FACTS AND PROCEEDINGS.
On August 6, 1982, the court of appeals issued
Municipality of Anchorage v. Serrano,
Based on the court of appeals’ retroactivity holding in
Lamb,
the district court denied petitioners’ motions to suppress because their breathalyzer tests were administered prior to August 6, 1982, the trial court had not ordered suppression in their cases, and their cases had not been consolidated with
Serrano
or
Cooley.
Subsequently, petitioners each pled nolo conten-dré to DWI charges, preserving their rights to appeal the suppression issue pursuant to
Cooksey v. State,
This court granted petitioners’ subsequent petition for hearing.
DISCUSSION.
We conclude that the court of appeals improperly denied retroactive application of the
Serrano
rule to petitioners’ cases.
1
The court of appeals purported to base its holding on our decision in
State v. Glass,
In
Serrano,
the court of appeals held that due process required the prosecution to take reasonable steps to preserve breath samples, stating that “[t]he ability of the defendant to ‘cross-examine’ these tests is critical to his case and to the integrity of the criminal justice system.”
As in a criminal prosecution for driving while intoxicated, the breath test is of central importance in the administrative license revocation proceeding. The ability of the defendant to evaluate these tests is critical to his ability to present his case. To deny a driver a reasonable opportunity to test the reliability and credibility of the breath test is to deny him a meaningful and fundamentally fair hearing.
Id. at 133 (citations omitted).
We have weighed certain criteria in determining the extent to which a new rule of law should be applied retroactively: (1) the purpose to be served by the new standards; (2) the extent of the reliance by law enforcement authorities on the old standards; and (3) the effect on the administration of justice of a retroactive application of the new standards.
State v. Glass,
Review of our prior decisions indicates that the purpose to be served by the new rule is of critical importance in determining the extent to which the new rule is to be applied retroactively. In
Lauderdale v. State,
we held that due process required suppression of breathalyzer test results if the state did not produce the ampoules used in the test.
In
State v. Glass,
we held that the rule suppressing warrantless electronic monitoring of a conversation between a police informant and a defendant was to be applied prospectively to activity occurring on or after the date of decision.
2
A review of the decisions of the Supreme Court of the United States dealing with retroactivity questions indicates that the starting point in analysis is the purpose criterion. Where the purpose of the new rule is primarily related to the integrity of the verdict, the application thereof has generally been extended to all cases....
On the other hand, where the purpose of a new constitutional standard is not .to minimize arbitrary or unreliable fact findings, but to serve other ends, retroactive application has generally been denied.
Id.
at 14,
quoting Rutherford v. State,
Finally, in
Howe v. State,
Since the finding of Howe’s guilt could have been affected by the court’s ruling, the considerations which we found persuasive in denying retroactivity to our opinion in State v. Glass,583 P.2d 872 (Alaska 1978), involving surreptitious monitoring of conversations, are not applicable.
Howe,
These authorities indicate that where a new rule serves to ensure defendants a fair trial, it must be retroactively applied at least to any case which was not finally disposed of 4 at the time the rule *641 was announced, provided that the defendant raised the point in the trial court. The Serrano rule clearly serves to ensure defendants a fair trial. Consequently, since petitioners’ cases were not finally disposed of at the time Serrano was announced, and since each had moved to suppress the results of his breathalyzer test on the ground that the police failed to preserve a breath sample, petitioners are entitled to receive the benefit of the Serrano decision.
REVERSED.
Notes
. Our holding makes it unnecessary for us to decide whether there were arrangements and understandings between the parties that would entitle petitioners to receive the benefit of the Serrano decision notwithstanding the court of appeals’ holding regarding retroactivity.
.
We retroactively applied the new rule to the named litigant and to cases under advisement by the court at that time.
. We further pointed out that law enforcement officials had reasonably relied on pre-Glass law and that retroactive application of Glass would have a substantial negative effect on the administration of justice. Id. at 14-15.
. We have denied broader retroactive application of a new rule going to defendant’s right to a fair trial on grounds of reasonable reliance by law enforcement officials on the old rule and potential impact on the administration of justice.
