On 15 June 1841, Hope wrote to Gladstone: Ormsby believed that Hope found some distraction from his frustration with the Anglican Church through his secular work. By 1839, Hope was becoming involved in parliamentary work. He was retained as counsel for the British government on the Foreign Marriages Bill and in 1843, the report on the Consular Jurisdiction Bill. His brother's appointment as Under Secretary of State for the Colonies in Sir Robert Peel's administration may have opened some doors. In 1843-44 he was engaged again by the government in the matter of the aftermath of the Pastry War, whose settlement Britain had arbitrated, to prepare a report on some points in dispute between France and Mexico. As an established ecclesiastical lawyer, he was much involved in the Ecclesiastical Courts Bill in 1843 and the same year he took the DCL degree at Oxford. In 1844 an English Criminal Code was under serious consideration and Bishop of LondonCharles James Blomfield recommended Hope to the Lord ChancellorJohn Copley, 1st Baron Lyndhurst as a commissioner to consider offences against religion and the Church. By the end of 1845 he stood at the head of the parliamentary bar but his objections to taking the Oath of Supremacy deterred him from accepting the professional honour of Queen's Counsel. In 1849, he therefore asked Lord Chancellor Charles Pepys, 1st Earl of Cottenham for, and was granted, a patent of precedence conferring equal status. In 1852 he gave Newman the disastrously misleading legal advice that he was unlikely to be sued for libel by Giacinto Achilli, advice which ultimately led to Newman's criminal conviction for defamatory libel. Thereafter, Newman relied on Badeley for legal advice, though in 1855 Hope-Scott conducted the negotiations which ended in Newman's accepting the rectorship of the Catholic University of Ireland.
Personal and family life
In 1847 Hope married Charlotte Harriet Jane Lockhart, daughter of John Gibson Lockhart and granddaughter of Sir Walter Scott. Six years after their marriage Charlotte came into possession of Scott's Abbotsford House estate, and Hope then assumed the surname of Hope-Scott. His wife died on 26 October 1858, and in 1861 he married as his second wife Lady Victoria Fitzalan-Howard, a daughter of the 14th Duke of Norfolk. Hope-Scott retired from the bar in 1870 and spent the rest of his life in charitable and literary work, in particular in making an abridgment of his father-in-law's seven-volume biography of Scott, with a preface dedicated to Gladstone. Hope-Scott maintained a lifelong correspondence with Badeley. Both his wives died in childbirth. He left an only daughter by his first marriage, Mary Monica, later wife of Joseph Constable Maxwell, third son of William, Lord Herries. Two other children of this marriage died in infancy. By his second marriage he left a son, James Fitzalan Hope, who was created Baron Rankeillour, and three daughters. Two other children of the second marriage also died young.
