INGRID LEARY (Labour—Taieri): Fakaalofa atu, Madam Speaker. I'd just like to pick up on a couple of points relating to retrospectivity and sanctity of contract referred to by the members Chris Bishop and David Seymour, and also the alleged transfer of responsibility from Government to business alleged by Andrew Bayly. There was a lot of discussion actually about retrospectivity. The lawyers of us who sat in the Finance and Expenditure Committee are well aware of the sanctity of contract, but sanctity of contract is not absolute and the courts historically have intervened in cases where there is a need to balance between freedom of contract and social duty. That happened in the 1940s, when good faith and conscionability came into play. It happens in marriage contracts; I don't think anyone would dispute that. And it happens where there is material unfairness and extraordinary circumstances.
