Input: Question: Which of three legal systems in the United Kingdom was created first? Passage:Sub-nationally, the United Kingdom has three legal systems, each of which derives from a particular geographical area and for a variety of historical reasons: English law, Scots law, and Northern Ireland law. Since 2007, as a result of the passage of the Government of Wales Act 2006 by Parliament, there also exists purely Welsh law. However, unlike the other three laws, this is not a separate legal system per se, being merely the primary and secondary legislation generated by the National Assembly for Wales, interpreted in accordance with the doctrines of English law, and not impacting upon English common law (except where such Welsh legislation ousts a common law rule by virtue of being a superior form of law). There is a substantial overlap between these three legal systems, and the three legal jurisdictions of the United Kingdom, these being England and Wales, Scotland, and Northern Ireland. Each legal system defaults to each jurisdiction, and court systems of each jurisdiction further the relevant system of law through jurisprudence. In private law it's possible for people in certain jurisdictions to use the law of other jurisdictions, for example a company in Edinburgh, Scotland and a company in Belfast, Northern Ireland are free to contract in English law. This is inapplicable in public law (for example, criminal law), where there are set rules of procedure in each jurisdiction. Overarching these systems is the law of the United Kingdom, also known as United Kingdom law or (more rarely) British law. British law arises where laws apply to the United Kingdom and/or its citizens as a whole, most obviously constitutional law, but also other areas, for instance tax law.
