End of the Institutions redress board ?

Article of front page of todays time which details that a man who was a victim of institutional abuse has been awarded €370,000 by the High Court.

This is nearly 300,000 more than the average award of the Institutions Redress award (77,000), so it looks like people will be scrambling to change their cases to the high court.
I'm not trying ot imply that any of the people who have brought cases of Institutional abuse are doing it for the money, and considering what many of them went through they are entitled to every penny they get but I'm sure their solicitors will now be advising them to bypass the redress board and go straight to the High Court (In fact a solicitor who is representing most of the claims was quoted in the times as saying that anyone whose claim has not already been dealt with by the redress board were now likely to take their case to the high court).

How did the goverment not see the potential of this happening ?
I mean we have already heard how the value of lands that the goverment will receive as a result of the Indemnity deal with the Religious orders will not cover anywhere near what the projected costs of payouts from the redress board will be, but now if all other cases go to the high court it could end up costing the state (i.e. we the taxpayers) millions more.
