However, the act was rarely invoked by the courts—the first court case to rule based on it was "Nagle v Feilden" in 1966, in a case brought by female horse trainer Florence Nagle against the Jockey Club's refusal to grant her a training licence on grounds of her sex. The one significant ruling as to the extent of the Act was not in a court of law, but rather in the House of Lords, where the Committee for Privileges was asked by Margaret Mackworth, 2nd Viscountess Rhondda to rule if the Act's provisions for exercising "any public function" extended to permitting a woman to sit in the House as a peeress in her own right. After some debate, it was held 22-4 that it did not. Women would not be permitted to sit in the Lords until 1958, when appointed female life peers were expressly permitted by the Life Peerages Act 1958, whilst hereditary peeresses gained the right to take their seats after the passage of the Peerage Act 1963.
