Procedure for hearing appeals: notice, record production, and limits on raising new grounds in sentence-only appeals. Procedure for hearing appeals not dismissed summarily requires the Appellate Court to give notice of hearing to the appellant or advocate, a State-appointed officer, the complainant in complaint-initiated convictions, and the accused where relevant, and to furnish them with copies of the grounds of appeal. The Court must then obtain the record if unavailable and hear the parties, though it may dispose of appeals solely about the legality or extent of sentence without the record. If the only ground is sentence severity, no other ground may be urged except with the Court's leave.
