This is a serious issue. I find it a little odd that if one promises to tell the truth and then misleads the committee, one can find oneself in jail but if one does not make that promise - it is merely implicit that one is going to tell the truth - one will not face the prospect of jail or a hefty fine. I find it odd that the consequences are so different, based on whether one promises to tell the truth and does not, as against not promising and also not telling the truth. Is there any offence if a person knowingly or recklessly gives evidence which is false or misleading if he or she has not taken an oath?
