The other one is around the reassessments, and the Minister spoke about it. I thought the previous rule was actually you could only go back five years—and the Minister talked about going back into the 1990s for one particular case. What this bill makes provision for is that there is a four-year period for going back retrospectively to make sure that if there are inappropriate or incorrectly calculated returns for child support, they can be retrospectively looked back over the past four years. You've got four years to make that application, but there are five exclusions, and that is the exceptions apply where information provided by a person in the child support assessment is fraudulent. The second one is where a person who's providing the child support has died. The third one is where a person should never have been made liable; there's been an incorrect allocation. Fourthly, amendment is required for the purpose of avoiding double liability, and sometimes that can happen. And, finally, a court order is received—that applies to an earlier period. I think, again, those exceptions create enough tolerance to reflect life—its circumstances—but also give adequate time for reassessments to take place.
