Maule’s father was a self-supporting provincial surgeon and his mother came from a Quaker family in Leeds.
Maule worked as a mathematical coach in Cambridge and amongst his pupils were the future judges Sir Cresswell Cresswell and Sir Edward Ryan.
Being of ‘Liberal politics’, he had been present at the hustings in Liverpool in 1812 as a supporter of Henry Brougham in his contest with George Canning.
Maule’s parliamentary career was brief. As a ‘Whig and something more’, he staunchly supported Lord Melbourne’s ministry, but is not known to have served on any select committees or introduced any bills.
A supporter of the Irish poor law, Maule opposed O’Connell’s attempt to postpone the introduction of the relevant bill, 9 Feb. 1838, and voted for its third reading, 30 Apr. He voted in favour of Grote’s ballot motion, 15 Feb., but otherwise divided with the Whig ministry on most issues, including its policy towards Canada, 7 Mar., and its proposal to use surplus Irish Church revenues for the education of all classes ‘without distinction of religious persuasion’, 15 May. He also supported the government motion to overturn a vote in favour of the immediate cessation of slave apprenticeships, 28 May. Regarding Irish municipal reform he voted with the government in support of a £5 Irish municipal franchise, 11 June, and divided in favour of the bill’s third reading, 25 June 1838.
Although it was believed that Maule might, ‘had he exercised himself … have taken a distinguished rank in the house’, he was not a natural politician.
In January 1858 Maule, who never married, died ‘rather suddenly’ from the effects of bronchitis at the home he shared with his widowed sister, Emma Maria Leathley, and his unmarried niece, Emma Leathley, at Hyde Park Gardens, London.
