Also bear in mind that the recovery of damages through the civil courts for a criminal action isn't new at all but has always been available.
For example, if you get beaten up, you can recover money from the CICB (Criminal Injuries Compensation Board) for your injuries, however this is likely to be well below what you would be awarded in a civil court.
You can then sue your attacker for damages in excess of that awarded by the CICB, however in a lot of cases the assailant has limited or no means, and as I mentioned before, there is little point in pursuing such an individual as it's costly and will not result in any money being recovered.
Therefore it's not so much a matter of him being punished twice, if he had the money when he attacked the woman she could have sued him there and then. Plus it's hardly 'punishment' when you're compensating someone for the distress you caused them by your own actions. His punishment was the jail sentence, this case simply deals with the limitation act on whether he should still have to compensate the woman for the results of his actions.
