However, Hewitt will be allowed to appeal his sentence in the Supreme Court of Appeal in Bloemfontein. A date has yet to be provided.
Hewitt was handed eight years’ imprisonment for two counts of rape and a further two years suspended for sexual assault in the Pretoria High Court in May.
Two years of each prison sentence were suspended on condition Hewitt pays a total of R100 000 towards Justice Department campaigns against abuse of women and children.
Last month, advocate Johan Englebrecht told Judge Bert Bam he needed more time to prepare an application for leave to appeal Hewitt’s conviction.
Hewitt was convicted last month by Bam for raping Suellen Sheehan and Theresa Tolken, and sexually assaulting one other woman who may not be named.
Sheehan was 12 years old when she was attacked by Hewitt in 1982 and Tolken was 13 in 1980 when Hewitt raped her.
