I think youre likely wrong. (but I don't know, not being the WTO or an attorney) Why dont you ask trade law experts?
US courts decide political issues, in the US between US citizens and companies, only.. for example, most of what we think of as national issues, gay marriage, abortions, holidays, everything that doesnt involve international commerce...
but WTO courts decide economic matters between countries All three nations have argued before its tribunals and dispute settlement body.. Their word is final and there is no appeal. . .
The undemocratic WTO, now the world's trade court, above all nations and other laws, can decide test cases such as the above with no appeal possible.
I don't think you understand the scope and function of the WTO. They have no authority to 'decide' any such 'case' between the parties you mention. Nor would any sane court (not ruling out insane courts, mind you) ever rule on such a case in a way that would be broadly precedential. I don't know what venue this might appear in, but a US court would probably be inclined to rule that the so-called owners simply don't have standing to bring the case and just dismiss it on that basis. A Russian court, well good luck enforcing their judgment against John Deere.
Countries often break WTO law.. But then they get sued.. For example, because it sells insurance, the UK's NHS is breaking WTO law.. And has been ever since they left the EU. They have to update their domestic regulation as they agreed to in 1995. Everybody in the UK is going to need a raise to afford health insurance. Their NHS is probably going to be seen as a trade barrier. For example, Indian insurance companies often sell health inurance a-la-carte..Its very profitable.. Isnt that the whole point, profit? It certainly is. There are other pending disputes that are important, and undecided.. what would be the applicable legal precedent when it comes to the booty of wars?
