Criminal law – Community protection notice. A challenge to the validity of a community protection notice (CPN) was not open to a person at trial by way of defence to a charge of breach of a CPN. Consequently, the Divisional Court held that: (i) a judge did not have to satisfy themselves as to a CPN's reasonableness and/or legality; (ii) a CPN issued by the police was valid until varied, discharged (subject to judicial review) or on appeal; and (iii) the prosecution was not under a duty to call the original evidence of which complaint was made to establish that the CPN had been lawfully issued.
