No. The appellate court may choose not to entertain argument by either the defendant or this office and will advise the parties that no argument will be permitted. The appellate court decides the vast majority of cases on the briefs and records without oral argument.
Following the submission of the case, with or without oral argument, the appellate court will issue a written opinion either affirming (upholding) the conviction or reversing (overturning) the conviction as to the guilt and punishment assessed against the defendant. Occasionally the court will only overturn the punishment assessed.
