This is probably one of the most complex things this Government or, in fact, any Government does is to run an emissions trading scheme (ETS). It has far-reaching consequences, it's complex in nature, and there are lots of opportunities for mistakes—mistakes that we will do our best to try and rectify before they happen through the legislative process, but, given the short period of time, we can't fully be confident that we have ironed all of those potential errors out. Actually, I'm sure that we will find there's an error in this bill somewhere along the line, but that doesn't mean we shouldn't necessarily support it. But it is an issue, and it's something that this Government must stop doing. You've got to get your act together and line your ducks up and get this legislation going through proper processes. These processes have been set out for a very long time for a very good reason: because mistakes happen. It even happens when we've got a really good process, but this is incredibly complex and we've opened ourselves up to all sorts of problems.
