Wrongs Act 1954

The amendments to this Act made by the Tortfeasors and Contributory Negligence Amendment Act 2000 apply to and in respect of a cause of action arising before the commencement of that Act in the same way as they apply to and in respect of a cause of action arising after that commencement, but this Act, as so amended, has no effect in the case of –

a cause of action in respect of which a court has given judgment or has reserved judgment (including in either case a judgment as to liability only), whether or not an appeal has been made against that judgment; or a cause of action in respect of which the parties have entered into an agreement to settle claims arising from that cause of action (including an agreement as to liability only).
