(1) A person who is
required to answer a question, or to discover or produce a document or thing,
in civil proceedings for defamation 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.
(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 any other action or proceedings.
