Spanish state police exceeded their authority in 2007 when they seized and searched a treasure hunting ship off the coast of Gibraltar owned by Tampa's Odyssey Marine Exploration Inc. and jailed the captain overnight.
Police had arrested him for refusing to allow the search.
A judge in Spain has cleared the captain of all charges in another chapter in the protracted fight over riches Odyssey retrieved from the 1804 shipwreck of the Nuestra de las Mercedes, which it code-named the Black Swan.
However, a U.S. District Court judge acting as an admiralty court in Tampa ruled eight months ago in favor of the Spanish government, rejecting Odyssey's "finders keepers" claims to 500,000 silver coins and recovered artifacts. Odyssey appealed and keeps the treasure under lock and key.
