This text examines the key principles of the law of criminal evidence in England and Wales against the backdrop of their broader practical and theoretical contexts. It takes into account the impact of major legislative changes, including the Youth Justice and Criminal Evidence Act 1999 and the Criminal Justice Act 2003. Significant recent cases are examined and where relevant, the European Convention of Human Rights and post-Human Rights Act cases are discussed. This new text is ideal for law undergraduates and students on the LPC and BVC courses.
