Appeal definitions clarify who qualifies as party, Presiding Officer, Registrar, and the scope of appellate terms under the Act. The rules define key terms for appeals under the Depositories Act: Act means the Depositories Act, 1996; appeal means an appeal under that Act; Appellate Tribunal denotes the securities appellate body; 'form' refers to appended forms. The rules also define 'Member,' 'Presiding Officer,' 'party,' 'Registrar,' and 'registry,' and provide that terms undefined here have the meanings assigned in the Depositories Act.
