The obtaining and execution of search warrants remains an area of operational risk for the police. The margin for error is often narrow. In two cases in the last year the courts have provided useful and important clarification of issues concerning search warrants that had not previously been definitively determined. Further guidance has also been given on how search warrant applications should be drafted, and the impact that disclosure obligations have on the process. Judicial guidance can sometimes (understandably) be overlooked by officers, but will be relied upon in any subsequent challenge. This article highlights the guidance given in recent cases which has important practical implications.
