Irish Laws of Evidence is a comprehensive and authoritative exposition of the laws and rules of evidence in Ireland. Each of the rules is set against the backdrop of its informing principle, and is examined in light of the Irish Constitution, ongoing statutory reform, and the fluctuating justifications for the rule. The principles and rules are further explored in the context of the new alternatives for the securing and giving of evidence facilitated by technology and science, such as DNA profiling, surveillance cameras, and testimony given from outside the court by television link. The work also unites in one volume many of the most important judgments delivered by the Irish courts on matters of evidence, proof, and criminal justice.
