Part 5: Equipment interference Section 128: Duty of telecommunications operators to assist with implementation
This section provides that a telecommunications operator served with a targeted equipment interference warrant is required to take steps to give effect to it.
	This duty only applies in respect of an equipment interference warrant issued to agencies – which are also permitted to apply for a targeted interception warrant. In all cases the Secretary of State or the Scottish Ministers will approve the proposed steps which the telecommunication operator is required to take, even if the normal warrantry process would not require their involvement. This means that targeted equipment interference warrants issued to the law enforcement officers listed at subsection (3) will be reviewed by the Secretary of State or the Scottish Ministers before a requirement can be imposed on a telecommunications operator
	This section does not require a relevant telecommunications operator to take any steps which are not reasonably practicable to take. If the relevant telecommunications operator has previously been served with a notice to maintain a permanent technical capability then the steps required to comply with the notice should be considered when determining if the steps required by the warrant are reasonably practicable.
	Subsection (7) provides that the duty to comply with a warrant is enforceable by civil proceedings brought by the Secretary of State against a person within the United Kingdom.
