A BARTENDER who raped his 10-year-old stepdaughter and indecently assaulted another was yesterday sentenced to 111/2 years' jail. The judge said he agreed with the younger victim, who described the defendant's conduct as ''disgraceful''. ''Your acts were disgusting and despicable,'' Deputy Judge Wong told the 40-year-old defendant in the High Court. ''You have shown no remorse whatsoever. ''This young girl had to come to court in front of the public to tell of her sad molestation and rape by you.'' He said the defendant, who was convicted on Thursday, was regarded as the father of the girls, now aged 13 and 15. ''You cherish the idea of them calling you 'daddy'. Is that what 'daddy' should do to his children?'' But for a Court of Appeal ruling that he had to follow an English precedent which said the starting point for rape should be five years, the judge said the sentence would have been much heavier. He said there were aggravating features in t he case - that the man was in a position of trust, the age of the raped girl, and the fact she had to give evidence in public, which had caused her extreme distress. He imposed a sentence of 10 years for rape and six months for each of the three counts of indecent assault, two on the younger girl and one on her older sister, to run consecutively. In mitigation, Luke McGuinniety said it seemed no psychological harm had been caused to either girl. He said the incidents were relatively isolated and there was no violence involved. The defendant was still supported by the girl's mother, who was in court for the sentencing, he said. The court had heard that the man had been regarded by the two sisters as their surrogate father since 1989, when their mother started living with him. Their natural father died a year earlier. The girls testified that between 1989 and 1991 they were indecently assaulted by their stepfather, and the younger girl said she had been raped once.
