U.S. judge says Argentine debt payment illegal, should be returned

(Adds Argentine government comment)

NEW YORK, June 27 (Reuters) - A U.S. judge on Friday called Argentina's decision to make a sovereign debt payment in defiance of a court order an "explosive action" and told Bank of New York Mellon to return the money to the government.

U.S. District Judge Thomas Griesa in New York told lawyers representing Argentina and BNY Mellon that any attempt to make payment to bondholders without complying with his court is illegal.

"It cannot be done and it will not be permitted by this court. I want the banks and all concerned to know that... This payment cannot be made and anybody who attempts to make it will be in contempt of court," said Griesa, who was appointed to the court by U.S. President Richard Nixon in 1972.

On Thursday, Argentina deposited $539 million in BNY Mellon's account at the Central Bank of Argentina intended only for bondholders who participated in two sovereign debt exchanges in 2005 and 2010. In total the government transferred $832 million for payment to various bondholders.

In a statement, Argentina's government fired back, saying Griesa was abusing his power and going beyond his jurisdiction by blocking its attempt to pay holders of its restructured bonds. It said the transferred money no longer belonged to Argentina.

"He has tried to provoke our country to default," the government's statement said, calling Griesa's decision "senseless and unheard of."

Argentina said the deposit was made in order to meet a June 30 coupon payment deadline. There is a 30-day grace period, however, before a default can be declared if exchange bondholders do not receive their money.

Argentina was ordered by Griesa in 2012 to pay holdouts, who did not participate in the debt exchange, $1.33 billion plus interest on unrestructured bonds stemming from the country's $100 billion default in 2001-2002. The order was denied a hearing by the U.S. Supreme Court on June 16, effectively upholding the holdouts' victory in the U.S. 2nd Circuit Court of Appeals.

Holdout investors are led by Elliott Management's NML Capital Ltd and Aurelius Capital Management, two hedge funds that specialize in buying up deeply discounted or distressed debt and negotiating profitable settlements, often through the use of the courts.

BNY Mellon in court confirmed Thursday's deposit was made into its account and told Griesa it was seeking to comply with his orders.

"Those funds remain in that account. Nothing more has happened," BNY Mellon's lawyer, Eric Schaffer of Reed Smith, told Griesa. The firm offered no additional comment when asked what it would do with the money in its account.
