The other thing that I want to talk about, and Mr Brownlee has already alluded to it, is the issue of retrospectivity. What the Commissioner of Inland Revenue is able to do is go back through records, and, in fact, taxpayers are required to keep records for at least seven, and in some situations I think up to 10, years. We're being asked to consider a bill that will increase quite materially, on the face of it, the requirements of trusts to furnish information on an annual basis, with effect from 2021/22. But, actually, the commissioner has the power for some trusts, certain trusts, and I'm not sure which, because it's very hard for me to see within the bill. What Mr Parker, the Minister, has put in his explanation is actually a list of the criteria. We can see when it's not required—foreign trusts and so on—but I can't see where the "certain trusts" is further defined. I think that will need clarification.
