The federal criminal appellate process begins when a person is convicted at the district court. A conviction can occur after a jury trial or after a plea of guilty.
If a person has entered in to a plea agreement, the person may have agreed to waive many of their rights to appeal.
If a person had a jury trial, there can be some issues that can be argued on appeal. The first thing that occurs after judgement/conviction, is the attorney must file a “notice of appeal” which usually must be filed within ten days following the district court’s entry of judgment. If the government is appealing the district court’s decision, a timely notice of appeal may be filed within thirty days following entry of judgment.
