Wrong, the EU courts don't have jurisdiction over this in the case of the U.K. Even worse the EU courts have insufficient evidence to even bring a case. All they have is a document that allegedly claims this which at best case scenario was stolen by someone now on the run. Good luck bringing a case on that evidence. So the EU courts simply can't fine the UK or the USA because without further evidence all we have is a circumstantial claim.
Further any attempt to take money from the USA government by taking from US based companies would be illegal under international law, and is simply not going to happen.
