In 1922, a Dr Halliday Sutherland, secretary of the League of National Life (an anti-contraception group of mainly Catholics), wrote Birth Control: A Statement of Christian Doctrine Against the Neo Malthusians. In this, he was critical of Stopes and her work, and he made defamatory attacks which could be considered libellous, leading to her suing him for libel. At the end of the trail, the jury found in favour of Stopes, but the judge disagreed. Although the Court of Appeals reversed the judge's opinion, the House of Lords reversed it back. The trial caused her clinic's clients to double.
