3(1)Statements made or documents produced by or on behalf of a person are not inadmissible in any such proceedings as are mentioned in sub-paragraph (2) by reason only that it has been drawn to that person’s attention—
(a)that pecuniary settlements may be accepted instead of a penalty being determined, or proceedings being instituted, or
(b)that, though no undertaking can be given as to whether or not the Commissioners will accept such a settlement in the case of any particular person, it is the practice of the Commissioners to be influenced by the fact that a person has made a full confession of any fraudulent conduct to which he had been a party and has given full facilities for investigation,
and that he was or may have been induced thereby to make the statements or produce the documents.
(2)The proceedings mentioned in sub-paragraph (1) are—
(a)any criminal proceedings against the person in question for any form of fraudulent conduct in connection with or in relation to stamp duty, and
(b)any proceedings against that person for the recovery of any stamp duty or interest on unpaid stamp duty due from him, and
(c)any proceedings for a penalty, or on appeal against the determination of a penalty, in connection with or in relation to stamp duty.
