Mаrk Nelson appeals from a judgment of conviction on two charges of third-degree sexual assault. The sole issue raised by Nelson is whether еvidence proffered by the state of other similar crimes previously committed is admissible under sec. 904.04(2), Stats., at the defendant’s trial. We hold, howevеr, that this issue cannot be properly raised before this court since the defendant, by his guilty plea, waived his right to appeal the trial court’s ruling оn the admissibility of other crimes evidence. In addition, we hold that the circumstances of this case do not permit Nelson to invoke the excеption to the rule of waiver set forth in sec. 971.31(10), Stats. Accordingly, we dismiss this appeal.
Nelson was charged in a criminal complaint with second-degree sexual assault alleged to have occurred on December 14, 1980. At the preliminary hearing, testimony established that Nelson and Kay Ratliff mеt at a party in December 1980. At this party, Nelson asked Ratliff for a ride home. She agreed and drove him to his home. While parked in his driveway, the pаrties had sexual intercourse in her van. Ratliff claims that her consent was obtained only by the threat of force. Conversely, Nelson contends that Ratliff voluntarily consented to have sexual intercourse with him.
*700 After the preliminary hearing, an information was filed charging Nelson with the original offense of second-degree sexual assault. Nelson entered a plea of not guilty to this charge and appeared in Racine County Circuit Court on February 17, 1981 with his attorney, prepared to commence a jury trial.
Prior to commencing voir dire, the trial court was requested by counsel to rule on the admissibility of other crimes or wrong acts evidence which the state intended to offer during the course of the trial. The state sought to call three witnesses, Mary Lou Wаgner, Melody Conrad and Darlene Conrad, to testify as to incidents similar to Ratliff’s that they had had with Nelson. Nelson objected to the admissibility of this type оf evidence on the grounds that it was irrelevant and prejudicial.
The trial court, after reviewing the law in Wisconsin, ruled that this evidence would be admissible at trial under sec. 904.04(2), Stats., as proof of motive, intent, and general scheme or plan. The court’s rationale for this ruling was that the probativе value of this evidence outweighed its prejudicial effect. Subsequent to this evidentiary ruling, Nelson entered into a plea agreement. Nelson pled guilty to a charge of third-degree sexual assault in the Ratliff case and also pled guilty in the Mary Lou Wagner matter. At the time these pleаs were entered, Nelson attempted to preserve a right to appeal the evidentiary ruling. He was of the belief, as was the assistant distriсt attorney, that his right to appeal would not be foreclosed by the guilty pleas.
On March 26, 1981, the trial court entered judgment of conviction upоn the pleas and sentenced Nelson to two consecutive four year terms in prison.
Nelson argues that the trial court erred when it ruled that evidence of other crimes would be admissible under sec. 904.04(2), Stats. This court, however, finds that *701 this issue raised by Nelson is not an appealable issue. Henсe, we do not render a decision on the merits of this issue.
Our supreme court in
Mack v. State,
At the time the pleas were entered, Nelson’s counsel attempted to preserve а right to appeal the challenged rulings. Simultaneously,. the assistant district attorney suggested that Nelson’s right to appeal would not be foreclosed by the guilty pleas. The perception of the law by both attorneys is inaccurate. Because of Nelson’s misunderstanding of the true effect of his guilty pleas on his appeal rights, it could be argued that the pleas were not understandingly made, and, thus, his appeal rights would still be preserved. However, in an analogous situation, the supreme court stated:
The plea of guilty is not qualified by the intent of the defendant, but the fact of its being knowledgeably and understandingly made might be affected by such reservation at the time of entry of the plea. This would lead to a postconviction request addressed to the trial court for withdrawal of the plea, not to a postconviction petition to this court seeking to raise the . . . issuе [that the defendant incorrectly believed had been reserved for appeal] despite the plea of guilty. [Emphasis added.].
Foster v. State,
Nelson also contends that if the general rule of waiver is found to apply, sec. 971.31(10), Stats., would allow his appeаl to be heard. We disagree. Section 971.31 (10), creates the following narrow exception to the rule of waiver:
An order denying a motion to suppress evidence or a motion challenging thе admissibility of a statement of a defendant may be reviewed upon appeal from a judgment of conviction notwithstanding the fact that such judgmеnt was entered upon a plea of guilty. [Emphasis added.]
From the unambiguous language of this statute, this court concludes that sec. 971.31(10), is applicаble only in suppression situations. In addition, our supreme court made this clear when it stated: “Under the rule of statutory construction of
expressio unius est exclusio alterius,
this statute stops with the single exception it creates.”
Foster v. State,
In summary, we hold that the issue raised on appeal by Nelson cannot properly be raised before this court. 1 *703 Nelson cannot raise this issue becausе he waived his right to appeal the trial court’s ruling on the admissibility of other crimes evidence when he pled guilty to the two charges of third-degree sexual assault. We also hold that the narrow exception to the rule of waiver set forth in sec. 971.31(10), Stats., is not applicable since the triаl court ruling being challenged here does not involve a motion to suppress evidence. For these reasons, we dismiss this appeal.
By the Court. — Appeal dismissed.
Notes
While we hold that Nelson cannot properly challenge the trial court’s evidentiary ruling before this court, we are of the *703 opinion that the aрpropriate means of making such a challenge would be through a post-conviction request addressed to the trial court for withdrawal of the guilty plea. Withdrawal of the plea could be based on the grounds that Nelson relied on erroneous information.
