Perhaps I can answer that. It goes back to the earlier question. The duty to suspend is under subsections 45.74(1) and 45.74(2). There is a provision there that if the chair of the Public Complaints Commission finds that their review of a complaint could seriously hinder a criminal investigation, then under that provision the chair has a duty to suspend the complaint investigation until that criminal investigation is done.
The next provision gives that discretion to the commissioner. If the commissioner feels that it is interfering and prejudicing the criminal investigation, he or she can, in writing, ask the chair to cease. It's a stay, really, just to put it on hold. The commissioner has to explain the reasons for that request.
