America's Cup holders Alinghi have asked a New York court to disqualify Oracle if the US team does not present them with a description of the trimaran which they are building for their multihull duel.
The move comes two days after Oracle launched a new court action in New York against Alinghi which it accuses of trying to change the rules for the event.
A hearing has been set for next Wednesday at the Supreme Court of the State of New York in Manhattan at the request of Oracle to consider that complaint.
The two sides have been locked in a legal battle over the rules of the America's Cup, the oldest trophy in international sports, since Alinghi won the 32nd edition in 2007 in Valencia in eastern Spain.
Their duel to settle the 33rd America's Cup -- with Alinghi using a catamaran and Oracle a trimaran -- is set for February 2010 at a location which has yet to be fixed.
In its latest legal move, Alinghi asked the court to order Oracle to provide it with a description of its trimaran within the next 15 days so it can determine if the boat meets the rules of the America's Cup.
Alinghi skipper, the New Zealander Brad Butterworth has accused Oracle of seeking to win the 33rd America's Cup through the courts.
Rita Barbera, the mayor of Valencia which could host the duel, has urged the two sides to "return to the sea" or else the America's Cup risks becoming the "Cup of the courts".
