Where an accused convicted of indecent assault of a man had mistakenly been charged under the Sexual Offences Act 1956 s.14(1) instead of s.15(1) and had been found unfit to stand trial under the Criminal Procedure (Insanity) Act 1964 s.4A, the conviction was unsafe. Section 4A clearly stated that the jury had to be satisfied that the accused had done the act charged. Even though the indictment particulars were accurate, the actus reus of indecent assault on a woman could not be established by an indecent assault on a man.
ACTUS REUS OF INDECENT ASSAULT OF WOMAN NOT ESTABLISHED BY INDECENT ASSAULT OF A MAN.
