I don't have the time to reply to the posts today on this issue, but I'll just point out the current wording (perhaps can be better worded) is that the candidates are willing to undergo CRB (if the board determine [possibly with official legal / CC advice]) that it wises its members to undergo such checks. It does not state that the members will definitely go through CRB. It also does not state under what cases a member will be disqualified as a result from those checks. (i.e. petty crime? murder? ...)
