64. Power to tender immunity from prosecution.
(1) The Central Government or the State Government may, if it is of opinion (the reasons for such opinion being recorded in writing) that with a view to obtaining the evidence of any person appearing to have been directly or indirectly concerned in or privy to the contravention of any of the provisions of this Act or of any rule or order made thereunder it is necessary or expedient so to do, tender to such person immunity from prosecution for any offence under this Act or under the Indian Penal Code or under any other Central Act or State Act, as the case may be, for the time being in force, on condition of his making a full and true disclosure of the whole circumstances relating to such contravention.
(2) A tender of immunity made to, and accepted by, the person concerned, shall, to the extent to which the immunity extends, render him immune from prosecution for any offence in respect of which the tender was made.
(3) If it appears to the Central Government or, as the case may be, the State Government, that any person to whom immunity has been tendered under this section has not complied with the conditions on which the tender was made or is willfully concealing anything or is giving false evidence, the Central Government or, as the case may be, the State Government, may record a finding to that effect and thereupon the immunity shall be deemed to have been withdrawn and such person may be tried for the offence in respect of which the tender of immunity was made or for any other offence of which he appears to have been guilty in connection with the same matter.
