Moving quickly through now my remaining minute, we did talk about the purpose of orders quite considerably, because, with such great powers being given to the executive, it was important at least to be able to constrain his powers by saying at least that the detail of the order should match its purpose. And, in a particular case regarding self-isolation requirements and permitted work, we pointed out that the purpose appeared to be relaxing restrictions, so it couldn't fairly be said to fit under a purpose that was merely about preventing an outbreak. Of course, an order that imposes any restrictions at all is preventing an outbreak relative to not having the order at all, but nevertheless we thought that it would be helpful to have a more expansive purpose, and so we got there in the end.
