Holders of euro-denominated Argentine bonds plan to appeal a US judge’s ruling blocking the country from making payments on their debt, according to a court filing.

In a notice filed in Manhattan federal court, lawyers for the bondholders challenged an August 6 ruling from US District Judge Thomas Griesa that Argentina cannot pay the bondholders until it also pays holdout investors who refused to restructure their debt in the wake of Argentina’s 2001-2002 default.

Argentina defaulted after missing a July 30 deadline for payment

Meanwhile, Citigroup Inc and Argentina last Friday were granted an expedited appeal of another order from Griesa that barred future payments to holders of certain US dollar-denominated restructured bonds, after the judge allowed the bank to make a one-time payment.

Both appeals will be considered by the 2nd US Circuit Court of Appeals in New York. The court on Friday set oral arguments in the Citibank matter for September 18.

Argentina defaulted after missing a July 30 deadline for payments on restructured bonds. Officials have claimed the country fulfilled its obligations but was blocked by Griesa, whom they have criticised, saying he overstepped his authority.

In June, Argentina deposited $539 million in Bank of New York Mellon Corp’s account at the Central Bank of Argentina, earmarked for bondholders who participated in sovereign debt exchanges in 2005 and 2010. It also deposited funds with Citibank Argentina.

But Griesa blocked the payments, saying Argentina’s actions were an “illegal” violation of his prior orders.

The euro bondholders have argued that their bonds should be exempt because they are governed by the laws of England and Wales and paid through foreign banking institutions.
