Hedges was the son of Henry Hedges of Wanborough, Wiltshire, and his wife Margaret, daughter of Richard Pleydell of Childrey, Berkshire; he was educated at Magdalen Hall, Oxford. By patent for life he was created chancellor and vicar-general of the diocese of Rochester in 1686, where he was an advocate of moderation in a feverish time, and master of the faculties and judge of the Admiralty Court under William III, succeeding Sir Richard Raines, 1 June 1689, in which post he remained until his death, his expertise serving Parliament on numerous occasions. He was knighted shortly after his accession, on 4 June 1689. Hedges was returned as MP for Orford in 1698, under the aegis of Ormonde as Chancellor of Oxford, but after counter-petitions were presented, Hedges and his colleagues were unseated by an election committee, confirmed in the House by a majority of one vote In the brief parliament of February 1701 Hedges sat for Dover, and at the election in November 1701 he was returned for Malmesbury and for Calne. His opponents endeavoured to eject him from both places, and the election for Calne was voided, but the petition against his return for Malmesbury failed. At the next election he was again returned for both Calne and Malmesbury and elected to serve for Calne. He unsuccessfully contested the constituency of Calne again in 1705 and 1708, but nevertheless retained a seat in parliament, as he was thrice returned for West Looe, and once for East Looe. Hedges was a Tory supporter of Court policy, a client of Lord Rochester in contemporary eyes, but with manifest talent as a civilian lawyer, who usually voted in his own individual interest. Mainly through the influence of the Earl of Rochester he was sworn as secretary of state and privy councillor, when he was allowed by special permission of the king to remain judge of the Admiralty Court, and he continued to be judge until 29 December 1701. The Sarah, Duchess of Marlborough, supporting the Whig interest, said of him, "He has no capacity, no quality nor interest, nor ever could have been in that post but that everybody knows my Lord Rochester cares for nothing, so much as a man that he thinks will depend upon him'" He attended Queen Anne to Bath in August 1702, and for a short time he was declared the sole secretary, both home and foreign, until a successor was appointed to the Earl of Nottingham. During 1706 the Whigs constantly endeavoured to eject Hedges from office to make room for the Earl of Sunderland, and the queen at last submitted. The change was announced on 8 December 1706, but Hedges was mollified by promise of an appointment to the Prerogative Court of Canterbury, which came about in January 1711 on its vacation by Sir Richard Raines. Hedges sat in the commission for the rebuilding of St. Paul's Cathedral. In November 1711 he was rumoured to be considered for the third plenipotentiary to negotiate the treaty of Utrecht, but it never came to pass. Hedges' chief residence was from 1696 at Richmond Green, Surrey, which he sold to Sir Matthew Decker, 1st Baronet and in 1700 he bought the estate of Compton Camberwell, in Compton Bassett, Wiltshire, near his constituency of Calne; the Hedges arms are still preserved around the parapet of the house. He owned much property in Wiltshire and was buried at Wanborough.
Family
Hedges' widow, Eleanor, daughter of George Smith, a proctor in London, died in 1733, and was also buried at Wanborough. They had one daughter Anne and three sons, Henry, William, and Charles. His second cousin Sir William Hedges, a director of the Bank of England, had directed the Levant Company's "factory" at Constantinople.
