In the UK, the rule of law has arguably become a more significant and constitutionally important concept in recent years, as illustrated by direct reference to it as a 'constitutional principle' in the Constitutional Reform Act 2005, s 1. Interestingly, there is no definition of what is meant by the 'rule of law' in the Act. Instead, the drafters left it to the judges to interpret what the term means in the context of a case.
