109.This section makes provision for the purposes of determining liability for unlawful conduct by a designated civilian in reliance on a designation. In the case of a member of the police support staff, the Chief Constable is to be treated as the employer and accordingly a joint tortfeasor. In the case of contracted-out staff, such conduct is to be treated as conduct in the course of the person’s employment by the contractor and so the contractor will be a joint tortfeasor.
