That's interesting, thanks. I suppose the key then is the removal of it retroactively, and actually practicing that sensibly (like your drunk-driving example).

In the US, not having a parliament in the same way, I suppose what's missing (unless it isn't?) is for the congress/senate to be able to take it away in that way. I'm not at all familiar enough with their set up to know if that would be a completely wild precedent ('president is supposed to be supreme to them' etc.) though.
