Appellate Tribunal procedure is governed by natural justice and empowered to regulate procedure and enforce orders as civil decrees. The Appellate Tribunal is not bound by civil procedural code but must observe natural justice and may regulate its own procedure; it has civil court powers to summon witnesses, compel document production, receive affidavit evidence, requisition public records, issue commissions, and manage representations decided by default or ex parte. Orders of the Tribunal are enforceable as court decrees and may be executed by the competent local court; proceedings are deemed judicial and the Tribunal is treated as a civil court for certain penal and criminal procedure purposes.
