ACCRA (Reuters) - A court in Ghana upheld as legal on Thursday the detention of an Argentine naval vessel seized under a court order by creditors pursuing the South American nation over its 2002 debt default.
Argentina declared a sovereign default a decade ago and now faces a raft of lawsuits in U.S. courts by bondholders seeking state asset freezes to recover the value of defaulted bonds.
The Libertad, a Navy frigate with 200 crew, was detained in Ghana's eastern port of Tema on October 2 under a court order sought by NML Capital Ltd, an affiliate of the investment firm Elliott Management.
Argentina's Foreign Ministry issued a statement vowing to "employ all means afforded by the judicial system in Ghana and by the international courts in defense of its sovereignty."
Earlier, the country's defense ministry filed a motion contesting the detention. It said that, due to its military nature, the vessel could not be targeted by creditors.
In its ruling the commercial court in Ghana's capital Accra said Argentina had forfeited such immunities when it issued the bonds.
"The defense applicant had made it so clear in the transaction agreement that it was waiving such immunity and it is my view that the action being sought by the plaintiff is binding in accordance with the laws," the judge said in a statement.
Ace Ankomah, a lawyer for NML Capital, told Reuters his clients were seeking a bond deposit worth at least $20 million before releasing the vessel. Argentina owed his clients "well over $300 million", he said.
"We are not insisting on cash payment, neither are we asking for the full amount. Our position is that we'd release the vessel if they are able to get a bank to issue the bond to us," Ankomah said.
Bondholders like NML Capital, which the left-leaning government of President Cristina Fernandez calls vulture funds, normally target foreign bank accounts held by state-run companies or government agencies.
Defense lawyers said the ship, which is used as a training vessel, was running low on fuel and appealed to the court to allow refueling to provide power for the crew, all of whom remain aboard.
The Libertad was visiting Ghana as part of a west African tour. It is due to sail to Angola next.
