Very briefly, I come back to the very first point I made, which is that it's obvious the rules need to be harmonized in this area and in other areas. The way our laws have been developed has been to a large extent with a view to harmonization and understanding the principles.
I've demonstrated it in my writing and I can certainly give further evidence to this committee that those principles are in fact extremely uniform. Therefore, what looks like an enormous practical problem of implementation is sometimes less difficult when you actually work through it.
