(1) Evidence of an admission is not admissible unless the court is satisfied that the admission, and the making of the admission, were not influenced by:
(a) violent, oppressive, inhuman or degrading conduct, whether towards the person who made the admission or towards another person; or
(b) a threat of conduct of that kind.
(2) Subsection ( 1) only applies if the party against
whom evidence of the admission is adduced has raised in the proceeding an
issue about whether the admission or its making were so influenced.
