Offenders convicted at trial may appeal their cases. This means the entire case, from investigation through sentencing, can be reviewed by a higher (appellate) court. The defense submits a written brief noting the areas where errors may have occurred. Common reasons for appeal include an invalid arrest, improperly admitted evidence, and incorrect jury instructions.

Some offenders also may appeal the length of their sentences. The prosecution submits a brief responding to the offender’s arguments. These briefs, along with a transcript or tape of the trial, go to the appellate court for review. The attorneys also may present oral argument before the court.
