New York Authorization To Discontinue Appeal is a legal document used to withdraw an appeal filed in a New York State court. The document is also referred to as an Appeal Discontinuance Form and must be signed by an attorney of record or by the appellant in order to be valid. This document is required when an appeal is being discontinued in either the New York Supreme Court, Appellate Division or Court of Appeals. The form must include the case information, such as the title of the action, the court, the index number, and the names of the parties, as well as the reason for discontinuing the appeal. There are three types of New York Authorization To Discontinue Appeal: General Discontinuance (A-155A), Discontinuance of Appeal from an Order or Judgment (A-155B), and Discontinuance of Appeal from an Interlocutory Order (A-155C).
