In continuation of discussion I would like to submit that Section 131(1) empower the assessing officer as the powers vested in a court under the Code of Civil Procedure,95 of 1908 in connection discovery and inspection etc. The section 2(17)(d) the Code of Civil Procedure,1908 discussed about powers of officer of court to administer oath along with other judicial power. therefore, an income tax officer can administer oath during any proceeding.
