Darling was appointed a Justice of the
High Court in 1897, that of "
Chicago May", and the trial for criminal libel of
Noel Pemberton Billing MP (1918), brought by
Maud Allan after Billing and
Harold Sherwood Spencer had claimed there were 47,000 "sexual perverts" in high places who were controlled by the Germans. He also sat on the criminal appeals of
Hawley Crippen and
Roger Casement, The novelist and barrister
F. C. Philips gave his opinion, 'I think that the wittiest book ever written by a legal luminary was one called "Scintillæ Juris" by Mr. Justice Darling, when he was a barrister on the
Oxford Circuit. I understand that when he was raised to the Bench he stopped its circulation.' During the Billing trial one of the witnesses, Eileen Villiers-Stuart, claimed to have seen the mysterious "Black Book" in which the names of the "perverts" were listed, declared in court that Darling was one of them. She was later convicted of bigamy, and admitted that her testimony was invented. During the First World War,
Lord Reading, the
Lord Chief Justice, was frequently absent on diplomatic business. As the Senior
Puisne Judge in the
King's Bench Division, Darling deputized for him, and was sworn of the
Privy Council in 1917 as a reward. In retirement he spoke in the Lords on legal issues and sat in the
Judicial Committee of the Privy Council. He also sometimes sat in the King's Bench Division to deal with its arrears. He died at the Cottage Hospital, Lymington, Hampshire, on 29 May 1936 aged 86, and was succeeded as Baron Darling by his grandson, Robert Charles Henry Darling, his only son having predeceased him. == Family ==
