Albert Venn "
A. V."
Dicey KC (4 February 1835 – 7 April 1922) was a British
jurist and
constitutional theorist, and was the younger brother of
Edward Dicey. 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 and a leading constitutional scholar of his day. Dicey popularised the phrase "
rule of law", although its use goes back to the 17th century.
