Odyssey Marine Exploration and Spain have been arguing over the treasure since the trove was found last year at an undisclosed location in the Atlantic Ocean.

U.S. District Judge Steven Merryday ruled on Thursday that Odyssey's lawsuit claiming rights to the treasure could go forward provided the company promptly identifies the wreck for Spain, or gives its "best available hypothesis" of the identity.

At a court hearing on Wednesday, the company's lawyers said Odyssey did not know for certain the name or nationality of the wreck, from which the company recovered some 17 tonnes of silver coins and gold.

"We want to know the identity of this vessel, and what this ruling is saying is 'It's not an answer to say we haven't decided for sure,'" said lawyer James Goold, who is representing Spain.

Merryday ruled that parts of Odyssey's lawsuit could go forward through the courts, including claims for possession and ownership of the wreck and the artifacts.

But he sided with Spain on several other elements of the suit, dismissing Odyssey's claims for monetary damages from Spain and a request for an injunction to "secure the integrity of the recovery operation against interference from a third party."

The two sides have been at odds since Odyssey announced last May that it had found half a million silver coins and other artifacts. It said the wreck, which it code-named "Black Swan," was discovered in the Atlantic Ocean outside any country's territorial waters.

The dispute turned ugly when Spanish warships twice intercepted the company's treasure hunting ships after they left the British territory of Gibraltar and escorted them to Spanish ports.

The McDivitt Law Firm and My PSA Contest are asking high school students to create unique and compelling public service announcements that encourage fellow teens to abstain from the dangers of underage drinking and driving.

Alcohol related crashes are the second leading cause of teen death and children who begin drinking by age 13 have a 38 percent higher risk of developing alcohol dependence later in life.

McDivitt Law Firm hopes that, through this PSA contest, the messages created by teens specifically for their peers might prove to be one method for helping to prevent the tragedy and devastation, which are too often the result when teenagers drink and drive.

The contest is open to high school students in Colorado Springs, Pueblo and surrounding areas. Students are being asked to produce 28 to 29 second video PSA's. The PSA's will be judged on students' abilities to analyze and discuss the topic and produce a quality video. The winner will receive a laptop computer and the school the student attends will receive a monetary donation. The winning PSA will also be aired on TV.

In a speech marking the fifth anniversary of the creation of the Department of Homeland Security, Bush said U.S. officials have helped foil numerous planned attacks, including a plot to fly an airplane into the tallest building on the West Coast and another to blow up trans-Atlantic passenger jets.

"The enemy remains active — deadly in its intent — and in the face of this danger, the United States must never let down its guard," Bush said.

Bush continued to pressure the House to act on Senate-passed legislation needed to renew an intelligence law that governs how the government can eavesdrop on suspected terrorists. The law expired Feb. 16 and the House and Senate have yet to reconcile different versions of a new intelligence bill.

A top lawmaker voiced fears Tuesday that US President George Bush's administration was negotiating deals with Iraq that would amount to an open-ended commitment to stage US combat missions there.

Administration officials say formal US-Iraqi negotiations will begin later this month on a legal framework aimed at keeping security policy options open for both countries beyond 2008, when the UN mandate for US forces ends.

David Satterfield, the State Department's coordinator for Iraq, told a joint meeting of two congressional subcommittees Tuesday that "the agreements will not tie the hands of the next president or indeed this president.

"They will ensure that every policy option remains on the table," Satterfield told the lawmaking panels. "The size of the US presence in Iraq, the missions to be performed by such forces if forces are present, are decisions for the president and the next president to make," he added.

The so-called Strategic Framework and the Status of Forces Agreement (SOFA), he insisted, "will not include a binding commitment to defend Iraq or any other security commitments that would warrant Senate advice and consent.
