So, to use the vernacular, if I'm a hairdresser and I use vaccine certificates to say that you have to be vaccinated to come and get a haircut at my salon, what is the bit of the legislation that allows the Government to say, "To also work at that salon, you must be vaccinated." It's a very, very important point, because, if the bill doesn't allow the Government to do that, then the Government's got a massive legal problem on its hands, because the whole framework and the architecture that they are purporting to establish will fall down. So we need to know what the provision is, and if it turns out that a Supplementary Order Paper is required and the Government's overlooked something, well, then we'll have to have a look at it, but we need to know what the answer is.
