Scots criminal law governs the rules of criminal law in Scotland. Scottish criminal law relies far more heavily on common law than in England and Wales. Scottish criminal law includes offences against the person of murder, culpable homicide, rape and assault, offences against property such as theft and malicious mischief, and public order offences including mobbing and breach of the peace. Scottish criminal law can also be found in the statutes of the UK Parliament with some areas of criminal law, such as misuse of drugs and traffic offences appearing identical on both sides of the Border. Scottish criminal law can also be found in the statute books of the Scottish Parliament such as the Sexual Offences (Scotland) Act 2009 asp 9 and Prostitution (Public Places) (Scotland) Act 2007 asp 11 which only apply to Scotland. In fact, the Scots requirement of corroboration in criminal matters changes the practical prosecution of crimes derived from the same enactment. Corroboration is not required in England or in civil cases in Scotland. Scots law is one of the few legal systems that require corroboration.
The Crown Office and Procurator Fiscal Service (COPFS) provides independent public prosecution of criminal offences in Scotland (as the more recent Crown Prosecution Service does in England and Wales) and has extensive responsibilities in the investigation and prosecution of crime. The Crown Office is headed by the Lord Advocate, in whose name all prosecutions are carried out, and employs Advocates Depute (for the High Court of Justiciary) and Procurators Fiscal (for the Sheriff Courts) as public prosecutors.
