Duration, modification and cancellation of warrants

162 Duration of warrants

(1) A bulk acquisition warrant (unless already cancelled) ceases to have effect at the end of the period of 6 months beginning with—

(a) the day on which the warrant was issued, or

(b) in the case of a warrant that has been renewed, the day after the day at the end of which the warrant would have ceased to have effect if it had not been renewed.

(2) For provision about the renewal of warrants, see section 163.

163 Renewal of warrants

(1) If the renewal conditions are met, a bulk acquisition warrant may be renewed, at any time during the renewal period, by an instrument issued by the Secretary of State.

This is subject to subsection (6).

(2) The renewal conditions are—

(a) that the Secretary of State considers that the warrant continues to be necessary—

(i) in the interests of national security, or

(ii) on that ground and on any other grounds falling within section 158(2),

(b) that the Secretary of State considers that the conduct that would be authorised by the renewed warrant continues to be proportionate to what is sought to be achieved by that conduct,

(c) that the Secretary of State considers that—

(i) each of the specified operational purposes (see section 161) is a purpose for which the examination of communications data obtained under the warrant continues to be, or may be, necessary, and

(ii) the examination of such data for each such purpose continues to be necessary on any of the grounds on which the Secretary of State considers that the warrant continues to be necessary, and

(d) that the decision to renew the warrant has been approved by a Judicial Commissioner.

(3) “The renewal period” means the period of 30 days ending with the day at the end of which the warrant would otherwise cease to have effect.

(4) The decision to renew a bulk acquisition warrant must be taken personally by the Secretary of State, and the instrument renewing the warrant must be signed by the Secretary of State.

(5) Section 159 (approval of warrants by Judicial Commissioners) applies in relation to a decision to renew a bulk acquisition warrant as it applies in relation to a decision to issue a bulk acquisition warrant.

This is subject to subsection (6).

(6) In the case of the renewal of a bulk acquisition warrant that has been modified so that it no longer authorises or requires the carrying out of activities falling within section 158(6)(a)—

(a) the renewal condition in subsection (2)(a) is to be disregarded,

(b) the reference in subsection (2)(c)(ii) to the grounds on which the Secretary of State considers the warrant to be necessary is to be read as a reference to any grounds falling within section 158(1)(a) or (2), and

(c) section 159 has effect as if—

(i) paragraph (a) of subsection (1) were omitted, and

(ii) the reference in subsection (1)(c)(ii) to the grounds on which the Secretary of State considers the warrant to be necessary were a reference to any grounds falling within section 158(1)(a) or (2).

164 Modification of warrants

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

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

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

(b) providing that the warrant no longer authorises or requires the carrying out of activities falling within section 158(6)(a).

(3) In this section—

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

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

(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 warrant to be necessary (see section 158(1)(a)).

(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) A minor modification may be made by—

(a) the Secretary of State, or

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

(7) 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.

(8) If at any time a person mentioned in subsection (6) considers that any operational purpose specified in a warrant is no longer a purpose for which the examination of communications data obtained under the warrant is or may be necessary, the person must modify the warrant by removing that operational purpose.

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

This is subject to subsection (10).

(10) If it is not reasonably practicable for an instrument making a major modification to be signed by the Secretary of State, the instrument may be signed by a senior official designated by the Secretary of State for that purpose.

(11) In such a case, the instrument making the modification must contain a statement that—

(a) it is not reasonably practicable for the instrument to be signed by the Secretary of State, and

(b) the Secretary of State has personally and expressly authorised the making of the modification.

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

165 Approval of major modifications by Judicial Commissioners

(1) In deciding whether to approve a decision to make a major modification of a bulk acquisition warrant, a Judicial Commissioner must review the Secretary of State’s conclusions as to whether the modification is necessary on any of the grounds on which the Secretary of State considers the warrant to be necessary.

(2) In doing so, the Judicial Commissioner must—

(a) apply the same principles as would be applied by a court on an application for judicial review, and

(b) consider the matter referred to in subsection (1) with a sufficient degree of care as to ensure that the Judicial Commissioner complies with the duties imposed by section 2 (general duties in relation to privacy).

(3) Where a Judicial Commissioner refuses to approve a decision to make a major modification under section 164, the Judicial Commissioner must give the Secretary of State written reasons for the refusal.

(4) Where a Judicial Commissioner, other than the Investigatory Powers Commissioner, refuses to approve a decision to make a major modification under section 164, the Secretary of State may ask the Investigatory Powers Commissioner to decide whether to approve the decision to make the modification.

166 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 acquisition warrant without the approval of a Judicial Commissioner, and

(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) The 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 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 165(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.

167 Cancellation of warrants

(1) The Secretary of State, or a senior official acting on behalf of the Secretary of State, may cancel a bulk acquisition 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 acquisition 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 communications data obtained under the warrant is no longer necessary for any of the specified operational purposes (see section 161).

(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 carrying out of activities falling within section 158(6)(a).

(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.
