The Law Commission Report on Expert Evidence in Criminal Proceedings

Viewpoint

The author notes that, two years after the publication of the Law Commission’s reform proposals, the prospect of legislation is remote given the fear about costs. He disagrees with critics of this delay in implementing a radical overhaul. He argues that the basic principles of the common law are sound, although in some cases they have not been adequately applied. He identifies these principles as a broad test of prima facie admissibility coupled with a power to exclude evidence whose potential prejudicial effect outweighs its probative value.
