List of national legal systems
Common law is currently in practice in Ireland, most of the United Kingdom (England and Wales and Northern Ireland), Australia, New Zealand, Bangladesh, India (excluding Goa), Pakistan, South Africa, Canada (excluding Quebec), Hong Kong, the United States (on a state level excluding Louisiana), and many other places. In addition to these countries, several others have adapted the common law system into a mixed system. For example, Nigeria operates largely on a common law system, but incorporates religious law.
Rule of law in the United Kingdom
The rule of law is one of the longest established common law fundamental principles of the governance of the United Kingdom, dating to Magna Carta of 1215, particularly jurisprudence following its late 13th century re-drafting. It as a minimum subjects an otherwise absolute monarch (executive) and all free people within its jurisdictions, primarily those of England and Wales, Scotland and Northern Ireland to legal doctrines known as the general principles of law. It has evolved to work only alongside equal application of the law to all free people 'equality before the law' and within the framework of the constitutional monarchy supports the legal doctrine of parliamentary sovereignty. Exactly what it entails beyond this and the way that different aspects of the rule of law principle are applied, depends on the specific situation and era.
