1. Introduction, principles, and key concepts
This chapter introduces the principles and key concepts underlying the law of evidence, with an emphasis on criminal evidence. It first explains the distinction between the law of evidence and evidence itself before turning to a discussion of fair trial by looking at Article 6 of the European Convention on Human Rights (ECHR), now part of English law as a result of the Human Rights Act 1998. The chapter then considers the main provisions related to evidence, including the presumption of innocence; privilege against self-incrimination; the right to examine witnesses; and admissibility of evidence obtained through covert surveillance, entrapment, or disclosure. It concludes by highlighting the importance of analysis of the relevance of the facts in a trial.
