Sir Charles Montague Lush (7 December 1853 – 22 June 1930) was a British barrister and judge.

[1] He was called to the bar by Gray's Inn in 1879, and joined the North Eastern Circuit.

[1] In 1910, Lush was appointed to the High Court and assigned to the King's Bench Division, receiving the customary knighthood on 13 October 1910.

[1] He retired from the bench in 1925 due to deafness, and was sworn of the Privy Council the same year, although he never sat on the Judicial Committee of the Privy Council.

[1] Although highly regarded as a barrister, he was not a successful judge: he was said to be too diffident and sometimes let personal feelings influence his decisions.
