Part way through a District Court jury trial before Judge Turner, Mr Abbott pleaded guilty to the charges. He was sentenced to seven months home detention, after considerations were made for remorse, reparation and Mr Abbott's historical dishonesty charges.
He then appealed the sentence, claiming it was "excessive and disproportionate" and that the victim was not as vulnerable as suggested.
Judge Turner's original starting point for the sentence was 12 months imprisonment, which the Court of Appeal found to be appropriate.
The Court of Appeal found the sentence was lenient, as attempting to pervert the course of justice was a serious offence.
It was also decided that Mr Abbott had only showed "some remorse", which appeared to be "more about the stressful situation he has put himself and his partner in than about any harm caused to the victim".
The appeal against his sentence was dismissed.
