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.
Law of the United Kingdom
English law refers to the legal system administered by the courts in England and Wales, which rule on both civil and criminal matters. English law is considered as the original of the common law and is based on those principles. English law can be described as having its own legal doctrine, distinct from civil law legal systems since 1189.
