The law relating to rights of entry, search and seizure has long been important and controversial. Richard Stone's book gathers together in one work all the information about entry powers under English law, not only in the context of criminal investigations but also in relation to civil procedures. It clearly defines the categories of persons and authorities who may lawfully exercise such powers as well as those who are subject to them. This updated edition takes into account recent changes in legislation, including the "Drug Trafficking Offences Act 1986", the "Police and Criminal Evidence Act 1984", and the "Criminal Justice Act 1988". Since the first edition there has been a marked increase in Anton Piller orders and Mareva injunctions; these are fully considered together with detailed discussion of important decisions such as "Adegbesan", "Longman", and "Francis & Francis".
