He resigned his post in 1855, angered by the passing of the Common Law Procedure Acts, but was recalled by the government, who gave him a peerage as Baron Wensleydale of Walton to allow him to undertake the judicial functions of the House of Lords, a role he fulfilled until his death on 25 February 1868.

He studied at The King's School, Macclesfield before matriculating to Trinity College, Cambridge on 28 February 1799, where he won the Craven scholarship, Sir William Browne's gold medal, and was fifth wrangler and senior chancellor's medallist in classics.

[2] Parke's early career as a barrister was not noted as particularly brilliant, but he was successful; in 1820, for example, he was junior counsel for the Pains and Penalties Bill 1820 against Caroline of Brunswick.

He was criticised for being too respectful of authority and unwilling to overturn precedent; John Coleridge accused him of being dedicated to the form of the law rather than the substance.

[9] There was a question at the time of whether the letters patent, which granted him a peerage "for the term of his natural life", allowed him to sit in the House of Lords; it was eventually decided that they did not, and a second set was issued with the usual form for Baron Wensleydale, of Walton, in the County Palatine of Lancaster on 23 July 1856.
