Me : a billion dollar question that no-one has an answer for. Lots of hand waving dismissal as it's "automatic" but that has not been tested. As a contracting party, I don't believe we have given notice to leave.
Me : Again, untested. As a contracting party we are already party to it. There's a competency issue but if UK took that path, it enters the realm of politics not just legal interpretation.
Me : Let us suppose UK brexit with "no deal" and claims it has access to the single market as a contracting member of the EEA and operates in such a way. What then?
X : But UK would have to join EFTA?
Me : Really? A real quagmire this one. We could even dock to EFTA.
Me : Of course but this is where we get into politics. No-one wants to be seen as putting up the barriers to trade especially in uncertain legal areas.
Me : Ah yes, bless their cotton socks - "UK is a member of the EEA only by virtue of its membership of the EU". That's far from clear - europeanfutures.ed.ac.uk/article-7323
Me : By who? The EEA is its own separate legal order. The UK Gov and EC can't just say this treaty ends and ignore the EFTA court. It's a mixed agreement. I don't think it's anywhere near as clear as you're saying.
X : There will be legal battles.
Me : There was always going to be legal battles.
Me : Who says anything about ECoJ having jurisdiction? You're talking matters of international law and matters for the EFTA court. I don't think this stuff is clear and settled.
Me : Well, we would be leaving the EU. Job done. The referendum said nothing about the EEA. That's a totally different thing as different as NATO and the UN.
