Well, we've already covered 3 on this page, and when you add in the Canon Law of the CofE & the Romans then that's 5 already. I suppose that we'll also have to add in European Law, at least for the next 2 years, so it seems I'm at least happy with 6 ! However, the key thing is that there is a clear adherence to the principle that the Civil Law of the UK is always paramount.
