Appellate Tribunal procedure guided by natural justice permits civil court powers and decree style enforcement of orders. The Appellate Tribunal, guided by the principles of natural justice, may regulate its own procedure and is vested with civil court powers to summon witnesses, require document discovery, receive affidavit evidence, requisition public records subject to evidence law, issue commissions, and dismiss or set aside representations for default; it may also prescribe other matters. The Tribunal's orders are enforceable as court decrees and may be sent for execution to the competent local court where the respondent resides or carries on business. Proceedings before the Tribunal are deemed judicial proceedings and the Tribunal is regarded as a civil court for certain criminal procedure and penal code purposes.
