Legal Systems Across the United Kingdom
England and Wales has a common law legal system, which has been established by the subject matter heard in earlier cases and so it is the law created by judges.
It originated during the reign of King Henry II (1154-89), when many local customary laws were replaced by new national ones, which applied to all and were thus "common to all".
Scotland has its own independent and in parts, clearly different judicial system with its own jurisdiction. The law of Scotland is not a pure common law system, but a mixed system. This law shows many similarities to Roman-Dutch law.
At present, as a result of EU legislation, many modern laws are applicable across the whole United Kingdom of Great Britain and Northern Ireland but there can be differences (for example, in property law where the law of Scotland resembles civil systems more than English law).
