In the science fiction franchise Star Trek, Section 31 is an autonomous intelligence and defense organization. It is presented as a special security operation, manned by Federation citizens, that is not subject to the normal constraints of Starfleet ethical protocols. The organization appears, or is mentioned, across nine episodes of Star Trek: Deep Space Nine and Star Trek: Enterprise as well as the 2013 movie Star Trek Into Darkness.
In the Star Trek storylines, Section 31 exists outside Starfleet Intelligence's influence and deals with threats to Earth's and, later, the Federation's security. Its operating authority stems from a provision of the Starfleet charter—Article 14, Section 31, from which its name is derived—that makes allowances for "bending the rules" during times of extraordinary threats.
Unlike other secret police organizations in the Star Trek universe, such as the Romulan Tal Shiar and the Cardassian Obsidian Order, Section 31 is not an actual branch of government. Accountable to no one, Section 31 focuses on external threats, and pursues those it identifies by whatever means it sees fit.
Little of Section 31's history has been revealed on-screen. Most references to the organization appear in episodes of Deep Space Nine, although Section 31 also appears in Star Trek: Enterprise. Several works of Star Trek spin-off fiction expand on Section 31's operations; Pocket Books published a four-part series profiling connections between Section 31's operations and the missions of James T. Kirk, Jean-Luc Picard, and the crews of Deep Space Nine and the USS Voyager. These novels explicitly link Section 31 to Fleet Admiral Cartwright's actions in Star Trek VI: The Undiscovered Country and Vice Admiral Matthew Dougherty's actions in Star Trek: Insurrection. Section 31 is also heavily featured in the Star Trek: Enterprise novel The Good That Men Do, in which Trip Tucker joins the organization after his supposed "death". The framing story of the novel, set in the 25th century, establishes that Section 31 may have ceased to exist, although it does provide details[clarification needed].
The film Star Trek Into Darkness features an alternative universe version of Section 31, which is run by Starfleet Admiral Marcus. In this timeline, Section 31 is a secret branch of Starfleet created to protect the Federation from external threats by developing weapons. Marcus' involvement in the organization includes awakening the cryogenically frozen Khan Noonien Singh, whose genetically altered intellect enabled Marcus to develop new weaponry, including the U.S.S. Vengeance, a state-of-the-art warship. Marcus' plans and role in Section 31 were halted by Khan and the crew of the USS Enterprise.
The implications of Section 31 have been described[by whom?] as "troubling" and its goals and methods "deeply questionable." Its methods include brainwashing, torture, assassinations and, as revealed by the end of the Deep Space Nine TV series, genocide, the crime that is most opposed by the Federation. The genocide involves the creation, by Section 31, of a virus designed to kill a single species, the Founders, with the aim of destroying the Dominion. Section 31 deliberately infected Odo with the virus, knowing he would spread it to other shape-shifters.
Throughout the series, several Deep Space Nine officers, including Julian Bashir, infiltrate Section 31. One of their aims was to obtain a cure for the virus which was threatening Odo's life; however, under orders from Captain Sisko, they ultimately collude in hiding the crime. This is part of a pattern of overall loss of moral credibility by Starfleet, in comparison to that which it had in The Original Series and The Next Generation. Deep Space Nine and Star Trek: Insurrection both "position the Starfleet authorities in a very dubious light."
