John Jeffcott

Sir John William Jeffcott (1796 – 12 December 1837) was the first judge of the Supreme Court of South Australia. He also served as Chief Justice of Sierra Leone. On 27 May 1836, Jeffcott accepted appointment as the first judge of the new colony of South Australia, a position he had first applied for when the colony was proposed in 1834. Jeffcott never officially held the title "Chief Justice of South Australia", which was not created until 1856.

Jeffcott travelled to Australia in September 1836, on the Isabella in the company of J. B. Hack and family, his arrangements for passage being made secretly to defeat the efforts of creditors to recover money from him. He arrived in Hobart, Van Diemen's Land (Tasmania) on 1 January 1837, where he became engaged to marry his cousin Anne Kermode. He proceeded to Adelaide, South Australia, arriving there on 21 April 1837.

Jeffcott became a close friend and advisor to the embattled Governor of South Australia, John Hindmarsh, and helped to smooth tensions between the Governor and his officers. As well as Judge, Jeffcott was also a member of the South Australian Legislative Council from 28 December 1836 to 12 December 1837) the source of both executive and legislative power in the colony.

On 13 May 1837, Jeffcott presided over the first Criminal Sessions. Seven prisoners were presented for trial before a jury, the foreman of which was Col. William Light. Apart from one other criminal case involving two Encounter Bay whalers charged with threatening to shoot another man in a quarrel between rival boats, these first Criminal Sessions appear to be the only occasion when Jeffcott actually sat as Judge. Jeffcott had lost all of his belongings when the ship in which they were being transported was wrecked, so he returned to Van Diemen's land in June 1837, and did not return to South Australia until September.

Jeffcott left Adelaide for Van Diemen's Land again on 19 November 1837. Henry Jickling, the only barrister in the colony, was appointed Acting Judge in Jeffcott's absence. While waiting for a ship at Encounter Bay, Jeffcott joined an expedition to explore the Murray Mouth. He drowned on 12 December 1837 when the overloaded whaleboat in which he was a passenger overturned in rough seas.

His brother William Jeffcott was also a barrister and in 1843 was appointed a judge of the Supreme Court of New South Wales for the District of Port Phillip.

Jeffcott Street and Kermode Street in North Adelaide are named after Sir John Jeffcott and Robert Kermode, the brother of Jeffcott's fiancée. Jeffcott Chambers, barristers' chambers adjacent to the Supreme Court building in Gouger Street, Adelaide, are also named for him.
