The United Nations trade agency UNCTAD said on Wednesday that the recent U.S. court ruling on Argentina’s debt erodes sovereign immunity and does not comply with the country’s own U.S. Foreign Sovereign Immunities Act. Buenos Aires has been stuck in a battle with a pair of hedge funds that chose not to take part in two past debt restructurings following Argentina’s 2001-2002 default and held out instead for full repayment. It has suffered a series of setbacks as U.S. courts have ordered Buenos Aires to pay the so-called holdouts along with its other creditors.
