(1) A person who is
required to answer a question, or to discover or produce a document or thing,
in defamation proceedings is not excused from answering the question or
discovering or producing the document or thing on the ground that the answer
to the question or the discovery or production of the document or thing might
tend to incriminate the person of an offence of criminal defamation.
(2) However, any
answer given to a question, or document or thing discovered or produced, by a
natural person in compliance with the requirement is not admissible in
evidence against the person in proceedings for criminal defamation.
