No person shall be excused from answering any question put to him by the said Commissioners or any of them, or by any such Judge, Magistrate or other officer as aforesaid, upon the ground of any privilege, nor on the ground that the answer to such question will tend to criminate such person.
But no statement made by any person in answer to any such question shall, except for the purpose of punishing him for wilfully giving false evidence upon such examination, be admissible in evidence in any criminal proceeding.
And every person who, upon such examination, is compelled to give evidence which may tend to expose him to penal consequences, shall he freed from all criminal prosecutions to which he may have been or may become liable or subject within any part of British India, and for anything done, by him in respect of any acts relating to which he is examined, unless the Commissioners who have, or the Judge, Magistrate or other officer who has, examined such witness, certify, in writing under, their or his hands or hand that the witness is not entitled to the protection lastly hereinbefore given, on the ground that he has not made a full and true disclosure touching all matters as to which he is so examined.
Nothing in this Act shall exempt any such witness from any civil suit to which he may be liable.
