A telecommunications operator that has been served with a copy of a bulk acquisition warrant by (or on behalf of) the implementing authority must take all steps for giving effect to the warrant that are notified to the operator by (or on behalf of) the implementing authority.

This is subject to subsection (3).

Subsection (1) applies whether or not the operator is in the United Kingdom.

The operator is not required to take any steps which it is not reasonably practicable for the operator to take.

Where obligations have been imposed on a telecommunications operator (“P”) under section 253 (technical capability notices), for the purposes of subsection (3) the steps which it is reasonably practicable for P to take include every step which it would have been reasonably practicable for P to take if P had complied with all of those obligations.

The duty imposed by subsection (1) is enforceable against a person in the United Kingdom by civil proceedings by the Secretary of State for an injunction, or for specific performance of a statutory duty under section 45 of the Court of Session Act 1988, or for any other appropriate relief.

In this section “the implementing authority” has the same meaning as in section 168.
