Littledale joined the northern circuit, and attended the Chester sessions. In 1813 he was appointed counsel to the University of Cambridge. He enjoyed a good practice. On 30 April 1824 he was appointed, in succession to Mr. Justice Best, to a judgeship of the King's Bench Division, though beyond being appointed John Hullock's colleague in managing the government prosecutions in Scotland in 1822 he had had little official recognition to that point. He took his seat on the first day of Easter term, 5 May 1824, and was knighted on 9 June.[1] He also became Serjeant-at-law at this point.[2]
Littledale resigned because of failing health on 31 January 1841. He was sworn a Privy Councillor, but died shortly after at his house in Bedford Square on 26 June 1842. He left £250,000. He edited John Skelton's Magnyfycence, an Interlude for the Roxburghe Club in 1821.[1]
Family
On 26 February 1821 Littledale married Hannah Timberlake.[2]
His only daughter, Elizabeth, married Thomas Coventry, barrister-at-law.[1]
