He was admitted a member of the Faculty of Advocates in 1835, and in 1852 he was made Solicitor General for Scotland in Lord Derby's first ministry, three months later becoming Lord Advocate,[4] a post he held from May to December of that year. In the summer of 1857, he famously served as counsel for Madeleine Smith, a Glasgow socialite who was the defendant in a sensational murder trial.[5] Smith was freed with a verdict of "not proven".
In March 1858 he resumed this office in Lord Derby's second administration, being returned to the House of Commons as member for Stamford. Again his tenure was brief, leaving office in July 1858. He was responsible for the Universities (Scotland) Act 1858, and in the same year he was elevated to the bench as Lord Justice Clerk, with the judicial title Lord Glencorse. In 1867 he was made Lord Justice General of Scotland and Lord President of the Court of Session.[4] He was made a Privy Counsellor in 1859, and awarded a Doctor of Civil Law (DCL) by the University of Oxford in 1859.
He died at Loganbank, a villa in Glencorse[7] south of Edinburgh on 20 August 1891, the day before his 81st birthday.[1] He is buried in his family vault in New Calton Cemetery.
Family
In 1842 he married Isabella Mary Wood (1820–1855), daughter of Alexander Wood, Lord WoodFRSE (1788–1864),[7] a judge and one of his senior colleagues. They had two sons, John David Inglis (1843–1861) and Harry Herbert Inglis WS (1848–1907).
He employed Rev Robert Keith Dick Horne as private tutor to his children.[8] Horne was later minister of Corstorphine Old Parish Church in west Edinburgh.
