District Court Judge Garry Neilson said just as gay sex was socially unacceptable and criminal in the 1950s and 1960s but is now widely accepted, “a jury might find nothing untoward in the advance of a brother towards his sister once she had sexually matured, had sexual relationships with other men and was now ‘available’, not having [a] sexual partner”.
He also said the “only reason” that incest is still a crime is because of the high risk of genetic abnormalities in children born from consanguineous relationships “but even that falls away to an extent [because] there is such ease of contraception and readily access to abortion”.
