Section 11: Implementation of warrants
103.This Section addresses the question of how an interception warrant may be implemented once it has been authorised, and the role of different people within this process.
104.Subsection (1) allows the interception to be carried out either by the person to whom the warrant is addressed (ie where it is technically feasible, by the intercepting agency itself), or by other persons providing assistance in the implementation.
