The Colombian government has laid out its legal defense in what could become the most expensive lawsuit in the country's history. Concretely, U.S. treasure hunting firm Sea Search Armada (SSA) is suing the South American for a share of what may be the largest treasure trove in maritime history, with valuations ranging from $4 billion to $20 billion.
But the Colombian government is adamant that the company, which claims to have found the San José galleon shipwreck in the 1980s, has no claim to the riches within.
