He was a judge of the King's Bench Division and of the Court of Appeal. He frequently sat in the Court of Appeal with Bankes and Atkin LJJ, a combination which has often been cited as one of the strongest benches ever to sit in commercial cases. On the criminal side he presided over the celebrated 1915 "Brides-in-the-Bath" trial of George Joseph Smith, and made a crucial ruling on "similar fact evidence" : Smith was charged with murdering only one of his recent brides by drowning her in the bath, but Scrutton ruled that the fact that two of his other brides had died in almost identical circumstances was admissible as evidence of a method or pattern of murder. Despite his great ability, Scrutton had a reputation as a difficult judge to appear before: "he did not suffer fools gladly, and often refused to suffer them at all" was one verdict. His stern appearance and sweeping beard intimidated most of those who appeared before him. His intolerance extended even to other judges, particularly the flamboyant and controversial Sir Henry McCardie whom he openly despised, and whom he attacked with increasing bitterness until their mutual antipathy resulted in a public quarrel. McCardie committed suicide soon afterwards, but the cause is generally thought to have been depression, unconnected to the quarrel. His reputation for being difficult may explain his failure to achieve further promotion to the House of Lords, since he was unquestionably well qualified on merit to be a Law Lord. In his later years he is said to have mellowed considerably: Henry Cecil, the judge and humourist, recalled in his memoir Just Within the Law that Scrutton, in the only case Cecil argued in front of him, had been perfectly polite, although he could not resist one dry comment that a barrister who feels that he must repeat every point four times cannot have much opinion of the Court's intelligence. James Atkin, Baron Atkin, his former pupil, always spoke of Scrutton with affection and respect
Personal life and family
In private life he had a passion for golf. He was noted for religious scepticism: at his death he left instructions that there should be "no empty Christian rituals" at his burial, although his wishes were either ignored or overlooked. His son Tom, in contrast to his father's scepticism, became a clergyman. He married Mary Burton in 1884 and had three sons and one daughter. The youngest son died in the First World War. Mary Midgley, the philosopher, was his granddaughter, and gave a valuable sketch of him in her 2005 autobiography An Owl of MInerva.
