@cwebberChristine Lemmer-Webber its probably going to be a disruptive and costly procedure but such organizations should maybe consider the feasibility of relocating their formal structures (not necessarily all their people) into EU / ECJ jurisdiction (maybe Luxemburg?)
Nothing is guaranteed anywhere when society implodes, but the multilateral nature of EU law and politics means collapse must be universal and not just a single country. Its one of the nice safety features of a federated system ;-)
