¶1(concurring).'
¶2I concur with the majority’s conclusion that the South Dakota convictions can be used to enhance the charges to felonies. I write separately to express my view that we do not need to invoke conflict of law principles to resolve this case. In State v. Warren, we recognized that collateral attacks of criminal convictions undermine finality of judgments and therefore are allowed only in “unique cases.” 419 N.W.2d 795, 798 (Minn.1988); see also Pilger v. State, 337 N.W.2d 695, 698 (Minn.1983) (“Generally, however, the trial court should only have to determine if the defendant was convicted and if the conviction was for an offense that corresponds to an offense in Minnesota.”). The facts presented here do not constitute the “unique case” where our jurisprudence permits collateral attack.
