5757 - Letter of marque

The stuff that goes on that I never hear about. Everyone else probably knew this.

"A letter of marque and reprisal (French: lettre de marque; lettre de course) was a government license in the Age of Sail that authorized a private person, known as a privateer or corsair, to attack and capture vessels of a nation at war with the issuer. After capturing, the privateers could bring the case of that prize before their own admiralty court for condemnation and transfer of ownership to the privateer. A letter of marque and reprisal would include permission to cross an international border to conduct a reprisal (take some action against an attack or injury) and was authorized by an issuing jurisdiction to conduct reprisal operations outside its borders."

...

"Article I of the United States Constitution lists issuing letters of marque and reprisal in Section 8 as one of the enumerated powers of Congress, alongside the power to tax and to declare war. However, since the American Civil War, the United States as a matter of policy has consistently followed the terms of the 1856 Paris Declaration forbidding the practice. The United States has not legally commissioned any privateers since 1815, although the status of submarine-hunting Goodyear airships in the early days of World War II created significant confusion. Various accounts refer to airships Resolute and Volunteer as operating under a "privateer status", but Congress never authorized a commission, nor did the President sign one. 

The issue of marque and reprisal was raised before Congress after the September 11 attacks and again by Congressman Ron Paul on July 21, 2007. The attacks were defined as acts of "air piracy" and the Marque and Reprisal Act of 2001 was introduced, which would have granted the president the authority to use letters of marque and reprisal against the specific terrorists, instead of warring against a foreign state. The terrorists were compared to pirates in that they are difficult to fight by traditional military means. On April 15, 2009, Paul also advocated the use of letters of marque to address the issue of Somali pirates operating in the Gulf of Aden. However, the bills Paul introduced were not enacted into law.

During the 2022 Russian invasion of Ukraine, the United States Congress considered a bill to "[authorize] the President to issue letters of marque and reprisal" in order to seize yachts owned by Russian oligarchs."
