Police – Police officer. The claimants were retired police officers who were assigned to be the handlers of covert human intelligence sources (CHISs). They sought to recover overtime pay which they said was due to them in respect of the time which they had spent dealing with CHISs outside their normal tours of duty. The Court of Appeal, Civil Division, in dismissing the defendant's appeal, rejected the submission that a recall to duty, under reg 25(1) of the Police Regulations 2003, SI 2003/527, depended upon the handler receiving some specific instruction from the controller to contact the CHIS or to take some other kind of positive action. Further, it allowed the claimants' cross-appeal as to the amount of overtime that was payable.
