The role of the courts and the judiciary in England and Wales are that the English legal system is often referred to as a �common law� legal system. Before medieval times the law in what we now call Great Britain was largely regional. Different regional kingdoms had different law. Over time, the same law was applied by judges across the single kingdom established after 1066 and so became common to all parts of the country. This was known as �the common law�.
This means that many of our primary legal principles have been made and developed by judges (rather than by the Parliament). Where the lower courts are bound to follow principles established by the higher courts in previous cases. The common law (or judge-made law) is at least as important to us as the law made by Parliament. For example, there is no Act of Parliament telling us that murder is a crime; it is a common law crime.
Another important role played by the judiciary is that of statutory interpretation. Whilst the meaning of law in a statute should be clear and explicit, this is not always achieved. Many cases come before the courts because there is a dispute over the meaning of a word in a statute. eg, the Dangerous Dogs Act 1991 contains the phrase �any dog of the type known as the pit bull terrier� but it did not say whether �type� meant the same as �breed�. So the interpretation of a statute may depend on the judge hearing the case. Once that interpretation has been made, however, it may form a precedent for later cases.
The advantages and disadvantages of the common law system that relies heavily on rules and rule making.
The law of England and Wales has been developed over many centuries. Historically, most important influences were local customs and judges. As Parliament became more powerful in the eighteenth century, statutes became a main source of new laws.
