Bad character evidence

The Criminal Justice Act 2003 applicable in England and Wales, and to a lesser extent Scotland and Northern Ireland, implemented fundamental changes to the admissibility of evidence relating to character, in respect to defendants and others. The Act is far-reaching, providing for the admissibility of previous convictions in support of a propensity to commit like-offences and untruthfulness. Common law rules in relation to the admissibility of bad character evidence have been abolished, with the existence of one exception.

The legislation draws heavily on the Law Commission Paper No. 273, with some deviations resulting from the Parliamentary debates as the Bill moved through Parliament.
