Sir Cecil Thomas Carr, KCB, QC, FBA (4 August 1878 – 12 May 1966) was an English lawyer.
As well as serving as Counsel to the Speaker of the House of Commons from 1943 to 1955, he was a key figure in the establishment of English administrative law.
Carr was called to the bar in 1902 but his practice remained small, giving him time to study.
He won the Yorke Prize in 1902 and 1905, published books on the law of corporations (1905) and collective ownership (1907), and edited a volume of trading company charters for the Selden Society (1913).
[1] In 1919, Carr left the armed forces and was appointed assistant to the editor of Revised Statutes and the Statutory Rules and Orders series.
