"I'd be interested to hear informed opinion counter to this position; as far as I can tell, existing legislation enables the government to trigger article 50 without a new authorisation from parliament." --- Tom7
This was my view too, and was the view of all three guest experts on BBC R4's Law in Action special on the Referendum result. However, the arguments presented by Mishcon de Reya do seem to suggest that it may not be that simple: as the UK constitution is unwritten, there seems to this non-expert a possibility that it could indeed be the case that one Act of Parliament can only be overturned by another.
* Mishcon website a bit slow at the moment, I think a lot more people are going to the horse's mouth to see for themselves.
