Facts

Mr Williams was a singing teacher. He told a 16 year old pupil that her breathing was not right and that he needed to perform an operation to improve her voice. He then had sexual intercourse with her. She did not understand that what he was doing was sexual intercourse, believing that it was a medical procedure. He was convicted of rape.

Legal principle

The Court of Criminal Appeal upheld his conviction. The girl had consented to what she believed was a surgical operation to improve her breathing, not to sexual intercourse, so she had been deceived about the nature of the act. Consent obtained by a deception as to the nature of the act is not real consent. The principle is now found in section 76 of the Sexual Offences Act 2003, which creates a conclusive presumption of lack of consent where the defendant intentionally deceived the complainant as to the nature or purpose of the act.
