5be renewed, at any time before the end of the relevant period, by an instrument
issued by the Secretary of State.

(2) The renewal conditions are—

164 Modification of warrants

(1) The provisions of a bulk equipment interference warrant may be modified at
any time by an instrument issued by the person making the modification.

(2) The modifications which may be made under this section are—

(a) 5adding, varying or removing any operational purpose specified in the
warrant as a purpose for which any material obtained under the
warrant may be selected for examination, and

(b) adding, varying or removing any description of conduct authorised by
the warrant.

(3) 10In this section—

(a) a modification adding or varying any operational purpose, or any
description of conduct, as mentioned in subsection (2) is referred to as
a “major modification”, and

(b) any other modification within that subsection is referred to as a “minor
15modification”.

(4) A major modification—

(a) must be made by the Secretary of State, and

(b) may be made only if the Secretary of State considers that it is necessary
on any of the grounds on which the Secretary of State considers the
20warrant to be necessary (see section 156(1)(b)).

(5) Except where the Secretary of State considers that there is an urgent need to
make the modification, a major modification has effect only if the decision to
make the modification is approved by a Judicial Commissioner.

(6) Section 157 (approval of warrants by Judicial Commissioners) applies in
25relation to a decision to make a major modification of a bulk equipment
interference warrant as it applies in relation to the decision to issue a bulk
equipment interference warrant.

Section 165 contains provision about the approval of major modifications made
in urgent cases.

(7) 30A minor modification may be made by—

(a) the Secretary of State, or

(b) a senior official acting on behalf of the Secretary of State.

(8) Where a minor modification is made by a senior official, the Secretary of State
must be notified personally of the modification and the reasons for making it.

(9) 35If at any time a person mentioned in subsection (7) considers that any
operational purpose specified in a warrant is no longer a purpose for which the
examination of material obtained under the warrant is or may be necessary, the
person must modify the warrant by removing that operational purpose.

(10) The decision to modify the provisions of a warrant must be taken personally
40by the person making the modification, and the instrument making the
modification must be signed by that person.

This is subject to subsection (11) (urgent cases).

(11) In a case where the Secretary of State considers that there is an urgent need to
make a major modification—

(a) 45the instrument making the modification may be signed by a senior
official designated by the Secretary of State for that purpose, and

Investigatory Powers BillPage 128

(b) the instrument must contain a statement that the case is an urgent case
in which the Secretary of State has personally and expressly authorised
the making of the modification.

(12) Despite section 154(1)(a) and (4)(b), the modification of a bulk equipment
5interference warrant 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 does not prevent the warrant from being
regarded as a bulk equipment interference warrant.

(13) Nothing in this section applies in relation to modifying the provisions of a
10warrant in a way which does not affect the conduct authorised by it.

165 Approval of major modifications made in urgent cases

(1) This section applies where—

(a) the Secretary of State makes a major modification of a bulk equipment
interference warrant without the approval of a Judicial Commissioner,
15and

(b) the Secretary of State considered that there was an urgent need to make
the modification.

(2) The Secretary of State must inform a Judicial Commissioner that the
modification has been made.

(3) 20The Judicial Commissioner must, before the end of the relevant period—

(a) decide whether to approve the decision to make the modification, and

(b) notify the Secretary of State of the Judicial Commissioner’s decision.

“The relevant period” means the period ending with the fifth working day after
the day on which the modification was made.

(4) 25If 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
30reasonably practicable, secure that anything in the process of being
done under the warrant by virtue of that modification stops as soon as
possible.

(5) The Judicial Commissioner may authorise further interference with equipment
for the purpose of enabling the person to whom the warrant is addressed to
35secure 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) 40if 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.

Investigatory Powers BillPage 129

166 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
5State, 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) 10that 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 161).

(4) 15But 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
20warrant 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.

Implementation of warrants

167 25Implementation of warrants

it is addressed (“the implementing authority”) may (in addition to acting
alone) act through, or together with, such other persons as the implementing
authority may require (whether under subsection (2) or otherwise) to provide
30the authority with assistance in giving effect to the warrant.

(2) For the purpose of requiring any person to provide assistance in relation to a
bulk equipment interference warrant, the implementing authority may—

(a) serve a copy of the warrant on any person who the implementing
authority considers may be able to provide such assistance, or

(b) 35make arrangements for the service of a copy of the warrant on any such
person.

(3) A copy of a warrant may be served under subsection (2) on a person outside
the United Kingdom for the purpose of requiring the person to provide such
assistance in the form of conduct outside the United Kingdom.

bulk equipment interference warrant includes any disclosure to the
implementing authority, or to persons acting on behalf of the implementing
authority, of material obtained under the warrant.
