207.Where an application is made for an intrusive surveillance authorisation and the case is urgent but it is not reasonably practicable for the application to be considered by the "senior authorising officer" (as defined in section 32) or his designated deputy, an authorisation may be granted by a person entitled to act in his/her absence. Subsection (4) lists the officers entitled so to act and subsection (6) sets down those officers entitled to act as "designated deputies".
