The appellant and the Attorney General’s Office filed a joint petition seeking a dismissal of the charges against the appellant. In the petition, the parties state that appellant was arrested on May 20, 1984; charged with theft of property on June 6,1984, and released on bond on June 8,1984. He filed a motion to dismiss the charges on January 31, 1986, which was denied on February 4, 1986. The parties claim that appellant’s right to a speedy trial has been violated and, accordingly, the trial court should be reversed and the charges should be dismissed.
We deny the parties’ petition. Without briefs on the issue we cannot determine if any excludable periods toll the speedy trial rule and we are unwilling to accept a decision on the merits made by the litigating parties. A litigant can waive the right to appeal or withdraw an appeal, but it is the function of this court to resolve legal issues on appeal and it is not permissible for the parties to usurp that function.
Accordingly the petition is denied and the parties are *38ordered to brief the issues.
