Investigatory Powers Act 2016 (c. 25)
Part 6 — Bulk warrants
Chapter 3 — Bulk equipment interference warrants
(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 187(4) does not apply in relation to the refusal to approve the
decision.
(5)
The Judicial Commissioner may authorise further interference with equipment
for the purpose of enabling the person to whom the warrant is addressed to
secure that anything in the process of being done under the warrant by virtue
of the modification stops as soon as possible.
(6)
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.
189
Cancellation of warrants
(1)
The Secretary of State, or a senior official acting on behalf of the Secretary of
State, may cancel a bulk equipment interference 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 equipment interference 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 material obtained under the warrant is no
longer necessary for any of the specified operational purposes (see
section 183).
(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 securing of
interference with any equipment or the obtaining of any communications,
equipment data or other information.
(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.
