Provided that no such immunity shall be granted by the Settlement Commission in cases where the proceedings for the prosecution for any such offence have been instituted before the date of receipt of the application under section 245C:

Provided further that the Settlement Commission shall not grant immunity from prosecution for any offence under the Indian Penal Code (45 of 1860) or under any Central Act other than this Act and the Wealth-tax Act, 1957 (27 of 1957) to a person who makes an application under section 245C on or after the 1st day of June, 2007.

(1A) An immunity granted to a person under sub-section (1) shall stand withdrawn if such person fails to pay any sum specified in the order of settlement passed under sub-section (4) of section 245D within the time specified in such order or within such further time as may be allowed by the Settlement Commission, or fails to comply with any other condition subject to which the immunity was granted and thereupon the provisions of this Act shall apply as if such immunity had not been granted.

(2) An immunity granted to a person under sub-section (1) may, at any time, be withdrawn by the Settlement Commission, if it is satisfied that such person had, in the course of the settlement proceedings, concealed any particulars material to the settlement or had given false evidence, and thereupon such person may be tried for the offence with respect to which the immunity was granted or for any other offence of which he appears to have been guilty in connection with the settlement and shall also become liable to the imposition of any penalty under this Act to which such person would have been liable, had not such immunity been granted.
