Whether the Appellate Tribunal has the same powers as that of Civil Court

Yes, to some extent the Tribunal is conferred with the powers of a Civil Court.

(a) summoning and enforcing the attendance of any person and examining him on oath;
(b) requiring the discovery and production of documents;
(c) receiving evidence on affidavits;
(d) subject to the provisions of sections 123 and 124 of the Indian Evidence Act, 1872, requisitioning any public record or document or a copy of such record or document from any office;
(e) issuing commissions for the examination of witnesses or documents;
(f) dismissing a representation for default or deciding it ex parte;
(g) setting aside any order of dismissal of any representation for default or any order passed by it ex parte; and
