US sanctions 'ruining lives', Iran tells UN court
The International Court of Justice (ICJ) in The Hague is hearing arguments this week from Tehran and Washington before deciding whether it has jurisdiction to deal with the case.
"The US measures and the underlying policy of maximum pressure disregard the very foundation of international law," Oloumiyazdi said.
The US urged the ICJ to reject the case on Monday, saying the sanctions have nothing to do with the friendship treaty, which predated the 1979 Islamic revolution in Iran and subsequent severing of ties between the two countries.
Washington formally ended the Treaty of Amity in late 2018 after the ICJ ordered it to ease sanctions on humanitarian goods as an emergency measure while the overall lawsuit is dealt with.
A decision on jurisdiction by the ICJ, which was set up after World War II to rule in disputes between nations, could take several months, while a final ruling would take years.
The 2015 nuclear deal -- involving the five permanent members of the UN Security Council -- Britain, China, France, Russia and the United States, plus Germany -- has hung by a thread since Trump pulled out.
