In an appeal, an appellate court reviews the record of the pre-trial
and trial proceedings for legal errors. The record includes the court
file, the court reporter’s transcript and the evidence and exhibits
introduced in the trial court. In general, an appellate court does not
consider information that is not contained in the record.
A post-conviction petition is the general name for what is called a
“collateral attack” on a conviction. In federal court, they are called
habeas corpus petitions. By using a post-conviction petition, a
defendant generally can bring evidence before the reviewing court that
was not part of the record on appeal, and in this way raise issues that
would otherwise not be reviewed.
