The UK's Criminal Justice and Immigration Act 2008 is the latest in a long line of criminal justice and immigration statutes. It contains a set of wide ranging provisions in respect of dealing with adult and young offenders, important procedural changes, new criminal offenses, and changes to UK immigration law. The breadth of the Act means that the changes significantly impact those working in the areas of criminal justice and immigration. Written by leading academic criminal lawyers, this book reproduces the Act in full, with a thorough and authoritative commentary on the provisions of the new Act and its likely impact. Matters contained in the Act include: changes to sentences of imprisonment or detention for public protection --- violent offender orders --- further changes to the rules relating to release and recall of offenders --- youth rehabilitation orders --- conditional cautions for young offenders --- anti-social behavior orders --- new criminal offenses (possession of extreme pornography, hatred on the grounds of sexual orientation, offenses relating to nuclear material and installations, etc.) --- the new law relating to special immigration status --- the new rules relating to reasonable force for the purposes of self-defense --- international co-operation in the enforcement of financial penalties --- changes to the powers of the Court of Appeal and other procedural changes.
