Chapter 1 — Bulk interception warrants
121
(b) notify the Secretary of State of the Judicial Commissioner’s decision.
“The relevant period” means the period ending with the third working day
after the day on which the modification was made.
(4)
If the Judicial Commissioner refuses to approve the decision to make the
modification—
(a) the warrant (unless it no longer has effect) has effect as if the
modification had not been made, and
(b) 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,
and section 146(4) does not apply in relation to the refusal to approve the
decision.
(5)
Nothing in this section affects the lawfulness of—
(a) anything done under the warrant by virtue of the modification before
the modification ceases to have effect;
(b) if anything is in the process of being done under the warrant by virtue
of the modification when the modification ceases to have effect—
(i) anything done before that thing could be stopped, or
(ii) anything done which it is not reasonably practicable to stop.
148
Cancellation of warrants
(1)
The Secretary of State, or a senior official acting on behalf of the Secretary of
State, may cancel a bulk interception warrant at any time.
(2)
If the Secretary of State, or a senior official acting on behalf of the Secretary of
State, considers that any of the cancellation conditions are met in relation to a
bulk interception warrant, the person must cancel the warrant.
(3)
The cancellation conditions are—
(a) that the warrant is no longer necessary in the interests of national
security;
(b) that the conduct authorised by the warrant is no longer proportionate
to what is sought to be achieved by that conduct;
(c) that the examination of intercepted content or secondary data obtained
under the warrant is no longer necessary for any of the specified
operational purposes (see section 142).
(4)
But the condition in subsection (3)(a) does not apply where the warrant has
been modified so that it no longer authorises or requires the interception of
communications or the obtaining of secondary data.
(5)
Where a warrant is cancelled under this section, the person to whom the
warrant was addressed must, so far as is reasonably practicable, secure that
anything in the process of being done under the warrant stops as soon as
possible.
(6)
A warrant that has been cancelled under this section may not be renewed.
