Domestic legislation is created by Parliament, which consists of the House of Commons, the House of Lords, and the Monarch. It is divided into primary legislation and secondary legislation. Primary legislation takes the form of ‘Acts of Parliament’, commonly referred to as ‘statutes’. Statutes can cover a vast variety of laws including criminal law, land law, contract law, and many others. Meanwhile, secondary legislation—also known as delegated legislation or subordinate legislation—is the most common instrument for implementing change within the UK. Parliament has neither the time, the resources, nor the expertise to deal with certain matters. It is for these reasons that the majority of legislation is made outside of Parliament. Accordingly, Parliament may delegate such powers, through an Act of Parliament to other bodies and institutions to implement. Such bodies often include the Privy Council, government ministers, local authorities, and other regulatory agencies.
