Subsection (6)
148.Subsection (6)adds a provision to section 7 of the ISA that actions carried out in relation to property overseas that have been authorised by the Secretary of State under that section, and that are capable of being authorised by a warrant under Section 5, may continue after a certain change of circumstances for up to five working days. These changes of circumstances are the discovery that the property to which the actions relate was actually in the British Islands, when it was previously believed that it was outside, or the discovery that the target had been brought into the British Islands. The period of five working days is deemed to have begun at the point that it first appears to a member of the Intelligence Service, or to GCHQ, that a change of circumstances has occurred.
