William Montagu (judge)
Montagu was the son of Edward Montagu, 1st Baron Montagu of Boughton. He was educated at Oundle School and admitted at Sidney Sussex College, Cambridge on 15 April 1632. He was admitted at the Middle Temple on 22 October 1635.
In 1660, Montagu was elected MP for Cambridge University in the Convention Parliament. He was elected MP for Stamford in 1661 for the Cavalier Parliament and sat until 1676. He became attorney-general to the Queen in 1662, holding the post until 1676. He was Treasurer of the Middle Temple in 1663 and Autumn reader in 1664. In 1676 he became serjeant-at-law and was Chief Baron of the Exchequer from 1676 to 1686. He sat on the Bench at several of the Popish Plot trials, and appeared just as credulous as the other judges; but at the trial of Titus Oates for perjury in 1685, under pressure from Jeffreys, claimed that he had never thought Oates a credible witness. He was removed from the bench in 1686 because he refused to give an unqualified opinion in favour of the prerogative of dispensation. He was assessor to the Convention in 1689.
