Appellate Tribunal procedure: guided by natural justice and vested with civil court powers enabling enforcement like a decree. The Appellate Tribunal may regulate its own procedure while remaining guided by the principles of natural justice, and is not bound by the Code of Civil Procedure. It has the same powers as a civil court to summon and examine witnesses, compel discovery and production of documents, receive affidavit evidence, requisition public records, issue commissions, dismiss or set aside representations for default or ex parte orders, and to enforce its orders as if they were a court decree; proceedings are deemed judicial and the Tribunal is treated as a civil court for certain criminal procedural purposes.
