A. V. Dicey

Albert Venn Dicey, (4 February 1835 – 7 April 1922) 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 LSE Law School, and a leading constitutional scholar of his day. Dicey popularised the phrase "rule of law", although its use goes back to the 17th century. Provided by Wikipedia
