A vast and minutely worded treaty of 2255 between the Federation and the Sheliak Corporate, which ceded several worlds to the Sheliak and governs the crisis over Tau Cygni V.
The Treaty of Armens was concluded in 2255 between the United Federation of Planets and the Sheliak Corporate. Because the Sheliak consider humanoid languages imprecise, the document runs to some half a million words and took hundreds of Federation legal specialists to draft. Among its terms it handed several Class H planets to the Sheliak.
The treaty is central to The Next Generation episode The Ensigns of Command. In 2366 the Sheliak invoke it to demand the removal of an unsuspected human colony on Tau Cygni V within days, and they refuse every request for more time.
Picard and Troi comb the text for a way out. Picard finally uses a clause on arbitration to name the Grizzelas, a species then in hibernation, as arbiters, which forces the Sheliak to grant the delay he needs.
