Course content

If a person is suspected of committing a crime, how does the prosecution go about proving that she is guilty? Are there any restrictions on the type of evidence that the prosecution can use to prove its case? What protections does the law offer to defendants in order to safeguard them against false conviction? These are among the central questions in the law of criminal evidence, that is, the set of rules governing the production and the use of evidence in criminal trials.


This course concentrates on criminal, rather than civil evidence, and emphasis is placed on matters of principle and conceptual issues rather than the fine detail of legal rules. The aims of the course are to teach students how to reason about evidence, and to encourage them to reflect critically on the modern law of criminal evidence.


At a more detailed level, we consider how inferences are drawn from evidence, and how basic ideas of probability can give insights on this process. We study the standard of proof, asking whether a high standard such as ‘proof beyond reasonable doubt’ is justified. As far as pre-trial procedures are concerned, we examine – among other things – how the police gain confessions from suspects and produce eyewitness identification evidence; we also look at how the law regulates the admissibility of these types of evidence. A central theme on the course is the question as to what makes a trial fair. The European Convention on Human Rights is relevant to this question. In this context, we look – among other things – at whether courts should admit improperly obtained evidence, and we ask what the privilege against self-incrimination is and whether it can be justified. As you will learn, much of the law of evidence involves rules of admissibility. Among these we cover ‘traditional’ rules such as those regulating the admissibility of hearsay evidence (a topic that now has an important human rights angle) and of bad character evidence (can a defendant’s previous convictions be introduced against her at trial?). We also look at particular problems relating to testimony, ranging from the protections afforded to vulnerable witnesses to the admissibility of evidence concerning the sexual history of complainants in trials for sexual offences.
