As amended through September 23, 2024
The only method of review in a criminal case in which judgment was entered on or after January 1, 1964, shall be by appeal. The party appealing shall be known as the appellant and the adverse party as the appellee, but the title of the case shall not be changed. Review of cases in which judgments were entered before January 1, 1964, shall be governed by the time limitations in effect on December 31, 1963, and the procedure shall be as provided by the rules then in effect,* or as provided by these rules, at the option of the appellant.
