It was impermissible for the Crown to prosecute a charge of indecent assault under the Sexual Offences Act 1956 s.14(1) in circumstances where the conduct upon which that charge was based was only an act of unlawful sexual intercourse with a girl aged under 16 in respect of which no prosecution could be commenced under s.6(1) of the Act by virtue of s.37(2) of, and Sch.2 to, that Act.
