It has the same powers as a civil court for summoning and examining persons, requiring discovery and production of documents, receiving affidavit evidence, issuing commissions, reviewing decisions, dismissing or setting aside default applications, and other prescribed matters. Proceedings are deemed judicial and the Tribunal is treated as a civil court for specified criminal procedural and penal provisions. The Presiding Officer may allocate business, transfer cases, and resolve bench disagreements.
