The legal system of Scotland. Owing to its separate development, Scotland has a system differing from the rest of the UK, being based on civil law. Its continued separate existence was guaranteed by the Act of Union with England in 1707. In the latter part of the 20th century England adopted some features already existing in Scots law, for example, majority jury verdicts, and the replacement of police prosecution by a system of public prosecution (see under procurator fiscal). There is no separate system of equity. The supreme civil court is the House of Lords, below which comes the Court of Session, and then the sheriff court (in some respects similar to the English county court, but with criminal as well as civil jurisdiction). More serious criminal cases are heard by the High Court of Justiciary which also sits as a Court of Criminal Appeal (with no appeal to the Lords). Juries have 15 members, and a verdict of `not proven' can be given. There is no coroner, enquiries into deaths being undertaken by the procurator fiscal.
