A great-grandson of Bishop Robert Skinner, Skinner was born on 22 October 1689, the third and youngest son of Robert Skinner of Welton, Northamptonshire, and of the Inner Temple. His father was judge of the Marshalsea court, and law reporter. Skinner entered Westminster School at the age of 14. Elected to a studentship at Christ Church, Oxford, he matriculated on 18 June 1709, and entered Lincoln's Inn on 20 June 1709. Skinner was called to the bar on 21 April 1716, and joined the Oxford circuit. In 1719 he purchased from Simon Urling, a place as one of the four common pleaders of the city of London, who then enjoyed the exclusive right and privilege of practising in the lord mayor's court. He was chosen as recorder of Oxford on 30 May 1721 and gave up his place as common pleader in 1722 to Thomas Garrard. Skinner's practice grew rapidly, and he was called to the rank of serjeant-at-law in Easter term, 1 February 1724, was made one of the king's serjeants on 11 June 1728, and became his majesty's prime serjeant by letters patent on 12 May 1734. He served as treasurer of Serjeants' Inn in 1728. After trying unsuccessfully to enter parliament for at the 1727 British general election, Skinner, who lived at Oxford from 1722 to 1739, was chosen Member of Parliament for the Oxford constituency at the general election of 1734. He was chosen as a Tory, but he soon went over to the Government. On 16 May 1737, he spoke in favour of the bill against the provost and city of Edinburgh after the Porteous riots. Skinner was appointed chief justice of Chester, and of the great sessions for the counties of Flint, Denbigh, and Montgomery and vacated his seat in Parliament on 26 November 1738. He occupied this judicial position, together with the recordership of Oxford, for the rest of his life. He was the second counsel for the Crown in the prosecution of Jacobite rebels on the northern circuit in July 1746; and led for the crown at Arthur Elphinstone, 6th Lord Balmerinoch's trial in the House of Lords the same year. Skinner died at Oxford on 21 October 1749, and was buried in Oxford Cathedral.
