Title: Law of the United Kingdom
Content:   The United Kingdom has four legal systems, each of which derives from a particular geographical area for a variety of historical reasons: English law, Scots law, Northern Ireland law, and, since 2007, purely Welsh law (as a result of the passage of the Government of Wales Act 2006 by Parliament). However, unlike the other three, Welsh law is not a separate legal system per se, merely the primary and secondary legislation generated by the Senedd, 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

Content:  The United Kingdom does not have a single legal system as Article 19 of the 1706 Treaty of Union provided for the continuation of Scotland's separate legal system. Today the UK has three distinct systems of law: English law, Northern Ireland law and Scots law. A new Supreme Court of the United Kingdom came into being in October 2009 to replace the Appellate Committee of the House of Lords.

Content:  The United Kingdom does not have a single legal system due to it being created by the political union of previously independent countries with the terms of the Treaty of Union guaranteeing the continued existence of Scotland's separate legal system. Today the UK has three distinct systems of law: English law, Northern Ireland law and Scots law. Recent constitutional changes saw a new Supreme Court of the United Kingdom come into being in October 2009 that took on the appeal functions of the Appellate Committee of the House of Lords.

Title: Law of the United Kingdom
Content:  There are three distinct legal jurisdictions in the United Kingdom: England and Wales, Northern Ireland and Scotland. Each has its own legal system, distinct history and origins.
Title: England
Content:   The English law legal system, developed over the centuries, is the basis of common law legal systems used in most Commonwealth countries and the United States (except Louisiana). Despite now being part of the United Kingdom, the legal system of the Courts of England and Wales continued, under the Treaty of Union, as a separate legal system from the one used in Scotland. The general essence of English law is that it is made by judges sitting in courts, applying their common sense and knowledge of legal precedent – stare decisis – to the facts before them. The court system is headed by the Senior Courts of England and Wales, consisting of the Court of Appeal, the High Court of Justice for civil cases, and the Crown Court for criminal cases. The Supreme

UK law arises from laws applying to the United Kingdom and/or its citizens as a whole, most obviously constitutional law, but also other areas, for instance tax law. The UK does not have a single legal system because it was created by the political union of previously independent countries. Article 19 of the Treaty of Union, put into effect by the Acts of Union in 1707, created the Kingdom of Great Britain but guaranteed the continued

Content:   Scots law is a unique legal system with an ancient basis in Roman law. Grounded in uncodified civil law dating back to the Corpus Juris Civilis, it also features elements of common law with medieval sources. Thus Scotland has a pluralistic, or 'mixed', legal system, comparable to that of South Africa, and, to a lesser degree, the partly codified pluralistic systems of Louisiana and Quebec. Since the formation of the Kingdom of Great Britain under the 1707 Acts of Union, Scots law has shared a legislature with England and Wales, and while each retained fundamentally different legal systems, the 1707 Union brought English and Welsh influence upon Scots law, and vice versa. Since the accession of the United Kingdom 
Title: Law of the United Kingdom
Content:   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 based on the principles of common law. English law can be described as having its own legal doctrine, distinct from civil law legal systems since 1189. There has been no major codification of the law, rather the law is developed by judges in court, applying statute, precedent and case-by-case reasoning to give explanatory judgments of the relevant legal principles. These judgments are binding in future similar cases (stare decisis), and for this reason are often reported. The courts of England and Wales are headed by the Senior Courts of England and Wales, consisting of the Court of Appeal,

Scots law is a hybrid system based on both common-law and civil-law principles. The chief courts are the Court of Session, for civil cases, and the High Court of Justiciary, for criminal cases. The Supreme Court of the United Kingdom serves as the highest court of appeal for civil cases under Scots law. Sheriff courts deal with most civil and criminal cases including conducting criminal

There is a substantial overlap between these three legal systems and the three legal jurisdictions of the United Kingdom: England and Wales, Scotland, and Northern Ireland. Each legal system defaults to its jurisdiction, each of whose courts further that law through jurisprudence. Choice of which jurisdiction's law to use is possible in private law: for example a company in Edinburgh, Scotland and a company in Belfast, Northern Ireland are free to contract in English law. This is not so in public law (for example, criminal law), where there are set rules
