Part 5: Equipment interference Section 124: Approval of modifications under section 123 in urgent cases
This section provides that once an urgent modification has been made by a law enforcement chief or an appropriate delegate a Judicial Commissioner must be informed.
	The Judicial Commissioner must decide whether to approve the modification and notify the person who made the modification of their decision within three working days. If the urgent modification is refused the modification will cease to have effect and the person to whom the warrant is addressed must, so far as is reasonably practicable, secure that anything in the process of being done under the warrant by virtue of that modification stops as soon as possible. The Judicial Commissioner may then, if required, authorise further interference for the purpose of enabling the person to whom the warrant is addressed to secure that anything in the process of being done by virtue of the modification stops as soon as possible.
