A statement made by a person in compliance with a requirement under section 447 may be used in evidence against him.
But in criminal proceedings in which the person is charged with a relevant offence—
no evidence relating to the statement may be adduced by or on behalf of the prosecution, and
no question relating to it may be asked by or on behalf of the prosecution,
unless evidence relating to it is adduced or a question relating to it is asked in the proceedings by or on behalf of that person.
A relevant offence is any offence other than the following—
an offence under section 451,
an offence under section 5 of the Perjury Act 1911 (false statement made otherwise than on oath), or
an offence under section 44(2) of the Criminal Law (Consolidation) (Scotland) Act 1995 (false statement made otherwise than on oath), or
an offence under Article 10 of the Perjury (Northern Ireland) Order 1979 (false statements made otherwise than on oath).
