;Procuring by parent :Section 9 forbade a parent or guardian from
procuring their child for sex with a third party. Originally it applied only to female children, but was extended to male children in 1988. The penalty was up to five years imprisonment, unless the child was a boy under the age of fourteen or a girl under the age of twelve, in which case the penalty could extend to life imprisonment. This section was repealed by the
2007 act, which created a broader new offence of "sexual exploitation of a child". ;Conspiracy :Section 11 made it a crime for two or more people to conspire to induce a woman to have sex by using false pretence or other fraudulent means. The penalty was imprisonment for up to five years. This section was repealed by the 2007 act, which instead includes a general conspiracy clause and the principle that fraud vitiates consent. ;Abduction :Section 13 forbade taking an unmarried person under the age of 21 out of the custody of his or her parents or guardian with the intent that he or she should have sex with either the abductor or with another person. The penalty was up to seven years imprisonment. The section was repealed by the 2007 act. ;Age of consent :In its original form, section 14 of the Sexual Offences Act made it a crime for a man to have sex with a girl or boy under the age of 16. In 1969 the age was raised to 19 for sex between two males (although such acts were also prosecutable as
sodomy). In 1988 equivalent provisions were added to make it a crime for a woman to have sex with a male under 16 or a female under 19. The penalty was up to six years imprisonment and a fine of up to R1 000; in 1988 the fine was increased to R12 000. :Section 14 was repealed by the 2007 act, which fixed an equal age of consent of 16 for all sexual acts. This act was not retrospective; however, the inequality in the old act between the ages of consent for heterosexual and homosexual sex was struck down as unconstitutional in the 2008 case of
Geldenhuys v National Director of Public Prosecutions. ;Mentally disabled people :In its original form, section 15 prohibited sex with a female "idiot or imbecile", meaning a person with a mental disability. In 1988 it was amended to also apply to males. The penalty was the same as that prescribed for violations of section 14 (see above). The section was repealed by the 2007 act, which created a number of new offences relating to exploitation of people with mental disabilities. ;Interracial sex :Section 16 contained the prohibition for which the name "Immorality Act" became infamous: it criminalised all extramarital sexual relations between a white person and a non-white person. (Interracial marriages were prohibited by the
Prohibition of Mixed Marriages Act.) The penalty was imprisonment for up to seven years. The section (along with the Prohibition of Mixed Marriages Act) was repealed in 1985. ;Use of drugs :Section 18 made it an offence to use drugs or alcohol to overpower a woman for the purpose of having sex; the penalty was up to five years imprisonment. The section was repealed by the 2007 act, which instead provided that a person whose judgement or consciousness is adversely affected by drugs or alcohol cannot consent to sex. ;Sex toys :Section 18A, inserted in 1969, prohibited the manufacture and sale of "any article which is intended to be used to perform an unnatural sexual act", i.e. some types of
sex toy. The section was repealed by the 2007 act. ;"Men at a party" :Section 20A, inserted in 1969, created the infamous "men at a party" offence. This made it a crime for any two men to commit, at "a party" an act which stimulated sexual passion or gave sexual gratification. The definition of "party" was, however, any occasion where more than two people were present. Although most sex between men was already illegal as
sodomy or "commission of an unnatural sexual offence", this provision was added in response to public scandal over gay parties raided by the police in Johannesburg. The penalty was up to two years imprisonment or a fine of up to R400, or both; the fine was increased to R4 000 in 1988. :In 1998 it was invalidated (retroactively to 27 April 1994) as unconstitutionally discriminatory, in the case of
National Coalition for Gay and Lesbian Equality v Minister of Justice, which also struck down the offences of sodomy and commission of an unnatural sexual offence. The section was formally removed by the 2007 act. ==Amendments==
