I'm afraid you're wrong. I think maybe the last time you mentioned that stuff I sat down with a couple of big WTO law books and started writing a massive post, but frankly couldn't be arsed to finish! Basically, your interpretation of Art. 2.4 TBT is fundamentally flawed and it doesn't mean what you think it does. Well, the interpretation of the sources you referred to back then, anyway. They have to bear international standards in mind, but they're allowed to make different ones if there's a reason to. They're just not allowed to construct artificial barriers to trade which don't have a legitimate reason and are just there as barriers/protectionism.
Any source for that? Or do you just hope I'll believe you?
This EFTA report shows that more than 90 percent of the laws of the single market include policy areas covered by UN or other global bodies. Norway has more influence in drafting laws originating from these sources than Britain, as we have to accept the "common position" agreed within the EU without the right of veto.
It's the same with standards - everything is going global. Who cares about having "influence" in the EU processes (which we don't) if standards are becoming increasingly global in nature? The entrepreneur on the Newsnight economics special made that exact point, the EU's "policies/standards etc" are becoming redundant as everything is going global.
The EU is an out-of date protectionist bureaucracy that's driven up food prices for everyone in the EU. Tariffs globally have been in decline for many years, and the further into the future we go the more and more irrelevant the EU's policies will be.
