Police – Powers. The present appeal concerned the question of the circumstances in which DNA profiles obtained by the police in the exercise of their criminal law enforcement functions could, without the consent of the data subject, be put to uses which were remote from the field of criminal law enforcement. The Court of Appeal, Civil Division, construed s 22 of the Police and Criminal Evidence Act 1985 as meaning that, if the police considered that it was necessary to retain DNA material obtained under Pt II of PACE for criminal law enforcement purposes, they could not use it for any other purpose.
