//The safeguard measures aren't permeant tho, NJ, and must be “restricted with regard to their scope and duration”//
Indeed, Zacs. They can be restricted in their duration until the problems the Protocol has thrown up no longer exist. Since that will require the EU to behave sensibly over the border they have insisted on within the UK and since that seems to be sometime never, the measures must last until then.

How is it doing away with the Protocol when it remains in place, albeit suspended under its explicit terms? I fail to see how you can say Brexit is not done. The UK is no longer a member of the EU (which was the point of Brexit). If we were still a member there would be no need for the Protocol. The border between the UK and the EU is settled – it’s in the Irish Sea. That arrangement is causing difficulties. There’s no need for it to do so because there are plenty of ways to ensure that only goods bound for the Republic are subject to scrutiny. But the EU won’t hear of that so they face the prospect of the UK making its own arrangements, outside the Protocol, courtesy of A16. Seems settled enough to me.
