May 29 (Reuters) - Argentina urged a U.S. judge on Friday to not expand by another $5.4 billion the amount it must pay holders of defaulted debt before it can pay the majority of its creditors who participated in two rounds of sovereign restructurings.
U.S. District Judge Thomas Griesa adjourned the hearing in New York without ruling on the matter, saying that these creditors, along with those he ordered paid $1.33 billion plus interest, should resume settlement discussions with the South American country.
"It is very important that all parties, including the Republic," get back to the negotiating table and settle the case, Griesa said before telling the parties he would "reserve judgment" on the motion brought by the government of Argentina. The court appointed Special Master Daniel Pollack nearly a year ago try to obtain a negotiated settlement.
The hearing concerned 526 creditors holding over $5.4 billion in money judgments or claims who filed paperwork by March 2. But Argentina says those numbers could increase if Griesa rules for the creditors, noting that in the New York federal court alone, $10 billion in judgments against the country are pending.
