Florida Appellate Practice: District Courts of Appeal

The purpose of Florida’s District Courts of Appeal is to provide the opportunity for thoughtful review of decisions of lower tribunals by multi-judge panels. District Courts of Appeal correct harmful errors and ensure that decisions are consistent with our rights and liberties. This process contributes to the development, clarity, and consistency of the law.

"Territorial jurisdiction" is an apt term to describe the judicial power of a district court over a given judicial circuit since the judicial power of the district courts is distributed geographically. It would also be proper to characterize the matter as one of appellate venue, however, since the issue relates only to the location of the forum. With that explanation, the former term "territorial jurisdiction" has been chosen for use throughout this book.
