But far more critical than that is this: this legislation changes the results or the meaning of commercial rental contracts that may have been written 10 years ago. This is far more important than any other legislation that this Government will try and pass in this two-week sitting block and perhaps actually this year. The significance of it is that normally when we pass a law in this Parliament, we pass a law but you can't be done for it if you broke it in the past. For example, if somebody was to catch a fish that was undersized now, if we raise the length of snapper that you're allowed to catch, you can't be prosecuted for having caught a fish that was too small 10 years ago by today's standards. You caught a 25-centimetre snapper. That was legal back in the day. Now the limit is much longer: 29, I think. You can't get done for catching an undersized snapper, by today's standards, 10 years ago. The laws don't apply to things you did in the past.
