The man's legal challenge had already been rejected by the South Australian Supreme Court. His lawyers argued that the "marital exemption" to rape was part of common law until the High Court ruled in 1991 that marriage did not mean a wife gave "irrevocable consent to sexual intercourse by her husband".
They also claimed that Australia was "by modern standards" very backward in the 1960s. Racial discrimination was legal, and there was no such thing as sexual harassment. David Bennett, QC, said the man would not have been convicted had he stood trial in 1963, and he urged the courts not to apply contemporary values to the law as it stood back then.
However, the five judges concluded that by 1963 changes to divorce, property and voting laws - all of which affected women's status - had removed any basis for accepting that argument. The other two judges disagreed, finding that in 1963 - however "abhorrent" the idea might seem now - it was not a crime for a man to rape his wife.
Bennett had already signalled that, if unsuccessful, he planned to mount a second legal challenge, arguing that his client could not receive a fair trial on charges dating back nearly half a century.
