If, before the commencement day, an information was laid for a warrant under subsection 85 (3) (Residential orders and supervision orders: entry and inspection by Director etc.) of the repealed Act but the magistrate had not issued a warrant or refused to issue a warrant, the laying of information is, on and after the commencement day, taken to be an application for the issue of a warrant under section 270 (Circumstance in which child or young person may be taken into safe custody) of this Act.
