Use of the termEdit
In 2257, following the disappearance of the USS Discovery into a wormhole, Spock suggested that all information on the ship, its crew and the Spore drive be sealed and any attempt to mention them would be brought up as treason. This was to prevent the discovery of the ship's true mission and prevent the return of Control. (DIS: "Such Sweet Sorrow")
In 2259 of the alternate reality, Montgomery Scott asked Captain James T. Kirk to beam him off the USS Vengeance, noting that he had committed treason against Admiral Alexander Marcus by sabotaging the ship. (Star Trek Into Darkness)
Various Starfleet-related acts of treason and traitors have been uncovered throughout history.
In 2365, Worf told Geordi La Forge, who was being held captive by Pakleds, that it would be treasonous to give them classified tactical information. This was part of a ruse to rescue La Forge by making the Pakleds believe he was a weapons expert. (TNG: "Samaritan Snare")
In 2370, Data told William T. Riker that he could not give orders because of the charges he faced upon his return from Arctus Baran's ship, having been declared a renegade. Treason was one of the charges he mentioned. (TNG: "Gambit, Part II")
