The powers and procedures of Settlement Commission are given in sections 25 and 26 of IGST Act. It is vested with the powers of a civil court under the Code of Civil Procedure, 1908, for discovery and inspection, enforcing the attendance of a person and examining him on oath, and compelling production of books of account and other records. Settlement Commission is deemed to be a civil court for the purposes of section 195 of the Code of Criminal Procedure, 1973. Any proceeding before it shall be deemed to be a judicial proceeding under section 193 and 228 and for the purpose of section 196, of the Indian Penal Code, 1860. The Settlement Commission also has the power to regulate its own procedure.
Section 193 of IPC, 1860 contains penal provision for giving false evidence during the proceedings and section 228 of IPC, 1860 contains penal provisions for intentionally insulting or interrupting the Officer sitting in settlement proceedings. Accordingly these provisions of IPC can be invoked where the person gives false evidence or interrupts the proceedings of the Settlement Commission.
Section 24 of the IGST Act gives power to Settlement Commission to amend its order to rectify any mistake apparent from the record within a period of three months from the date of the order. Such mistake may be noticed by the Settlement Commission on its own accord or may be brought to its notice by the applicant or the jurisdictional IGST officer. If a rectification has the effect of enhancing the tax liability or reducing the quantum of input tax credit, the applicant must be heard before the order is passed.
