Some Senators, especially Senator Finucane and Senator Kenneally raised the question of possible court challenges. The designation is not retrospective, but will apply to forthcoming events. It refers to contracts entered into since November 1999. That is covered by the Bill. Retrospection is not abhorrent to legislation. While it cannot apply in cases involving criminal sanction, there are a number of instances where it can take place. We are satisfied that in this area the legislation is proportionate and will withstand legal challenge.
