The ICC doesn’t have jurisdiction over civil matters. The ICC only has jurisdiction over the most egregious of war crimes, crimes against humanity and genocide, on a voluntary transnational basis (you have to be a signatory country, which I believe Argentina is).
Ah I get you, sorry, I stand corrected. Surely such a claim would come forward through the WTO though, would it not? Would the ICC (the Chamber of Commerce) have enough teeth as the forum for what’s surely a monumental case?
