ALBERT VENN DICEY
In the English system the checks and balances of the American system are not present. Historically in England the Monarch and the Parliament acted as checks upon each other. With a Constitutional Monarch there is no institutional check on Parliament. The checks are their restraint--respect for precedent--and the voters. The Prime Minister is a member of Parliament and has no powers other than what Parliament gives him/her. The courts in England are under Parliament and the upper house, the House of Lords is the equivalent of the highest court—but it may always be overruled by the parliament itself.
Albert Venn Dicey KC FBA (1835–1922), usually cited as A. V. Dicey, was a British Whig jurist and constitutional theorist. He is most widely known as the author of Introduction to the Study of the Law of the Constitution (1885). The principles it expounds are considered part of the uncodified British constitution. He became Vinerian Professor of English Law at Oxford, one of the first Professors of Law at the London School of Economics, and a leading constitutional scholar of his day. Dicey popularised the phrase "rule of law", although its use goes back to the 17th century.
