{{workinprogress}}''"A starship captain's most solemn oath is that he will give his life, even his entire crew, rather than violate the Prime Directive."''
:- '''James T. Kirk''', 2268
The '''Prime Directive''', also known as '''''[[Starfleet General Orders and Regulations|Starfleet General Order 1]]''''' or the '''Non-Interference Directive''', is the embodiment of one of [[Starfleet]]'s most important ethical principles: non-interference with other cultures and civilizations. At its core is the philosophical concept that covered personnel should refrain from interfering in the natural, unassisted development of societies, even if such interference was well-intentioned. The Prime Directive is viewed as so fundamental to Starfleet that officers swore to uphold the Prime Directive, even at the cost of their own life or the lives of their crew.

The "precursor" to the Prime Directive, though somewhat undefined, could be traced back to Captain Archer's and Doctor Phlox's ethical dilemma faced when encountering two species, one with a terminal genetic illness and the other without. Archer commented that eventually, Starfleet would have to "come up with some sort of a doctrine" establishing what humans should and should not do whilst exploring space and interacting with other lifeforms. They decided that interfering with the natural evolutionary course of these two species would go against the "directive" upon which they based their entire mission; to meet new species and attempt peaceful communications, not to "play God".

The fundamental principles were an important part of [[Earth]] [[Starfleet]] procedures as early as 2152, but it did not go into effect as a General Order until sometime after 2168. The directive remains in effect well into the [[24th century]] and applies to at least Starfleet and Merchant Marine personnel, but specifically does not apply to ordinary [[Federation]] citizens.

==Prohibitions==
{{quote|The Prime Directive is not just a set of rules; it is a philosophy... and a very correct one. History has proven again and again that whenever mankind interferes with a less developed civilization, no matter how well intentioned that interference may be, the results are invariably disastrous.|Jean Luc Picard, 2364}}

A complicated order, the Prime Directive has 47 sub-orders by the latter part of the 24th century. However, a high-level summary is "no identification of self or mission; no interference with the social development of said planet; no references to space, other worlds, or advanced civilisations." The directive provides guidance on what constitutes prohibited "interference" with a society, covering such matters as:
* Providing knowledge of other inhabited worlds (even if individuals or governments in the society were already aware of such)
* Providing knowledge of technologies or science
* Taking actions to generally affect a society's overall development
* Taking actions which support one faction within a society over another
* Helping a society escape the negative consequences of its own actions
* Helping a society escape a natural disaster known to the society, even if inaction would result in a society's extinction.
* Subverting or avoiding the application of a society's laws
* Interfering in the internal affairs of a society

==Scope and Interpretation==
:"''Someday my people are going to come up with some sort of a doctrine, something that tells us what we can and can't do out here; should and shouldn't do. But until somebody tells me that they've drafted that... directive... I'm going to have to remind myself every day that we didn't come out here to play God.''"
:: - '''[[Captain]] Jonathan Archer''', sensing the need for the Prime Directive in 2151

The Prime Directive does not apply equally to all societies on all planets at all times. Although a cornerstone of Federation philosophy, the scope of the Prime Directive varies depending on many factors. For example, the Prime Directive primarily applies to societies that had little to no actual knowledge of other worlds and space-faring civilisations (as with certain [[pre-warp civilisation]]s). But it also applies to the internal affairs of societies which know extensively of other worlds (for example, interference in purely internal affairs by Starfleet was not permitted in the [[memoryalpha:Klingon Civil War|Klingon Civil War]]). [[Human]] colonies were excluded from its coverage all together, and by virtue of joining the [[United Federation of Planets]] member planets were subject to its laws, regulations, and authority. The result is a spectrum of application: the more closely a civilisation is tied to the Federation or [[Earth]] the greater the amount of interference in that civilisation that is tolerated within the Prime Directive.

Some actions are clearly forbidden by the Prime Directive when it does apply to a society. Others are subject to interpretation, with commanding officers in Starfleet being given great discretionary powers regarding how and whether the Prime Directive would apply to specific situations. This promoted debate among command crews about whether the Prime Directive would (or should) apply, and how best to balance competing ethical priorities. If a decision was made by the commanding officer that could potentially be a violation of the Prime Directive, the conclusions and rationale would need to be recorded and justified to Starfleet through the ship's or station's logs. Anyone found to have violated the Prime Directive (including through claiming an unjustified exception or having a weak rationale regarding actions otherwise constituting a violation) could result in punishment ranging from a formal reprimand all the way to arrest and court martial.

==Exceptions==
:"''There can be no justice so long as laws are absolute. Even life itself is an exercise in exceptions.''"
:: - '''[[Captain]] Jean Luc Picard'''

There have been many exceptions to the applicability of the Prime Directive that were accepted by the Federation. Each was driven by the context of the situation, the society, and the circumstances at the moment. These were typically not full exceptions that voided the Prime Directive entirely; it was only suspended to the extent minimally necessary to address the matter at hand (e.g., answer a hail, provide rescue assistance). Also, actions were to be handled in a way that attempted to minimize the interference resulting from the limited suspension. For example, the attempted "repair" of prior cultural interference was not, itself, to be done in a way that would lead to even greater interference. These exceptions generally fall into the following categories:
* The society already knew of and contacted the Federation (e.g., seeking assistance; treaty matters)
* The society sent a general distress call to any space-faring cultures who might pick it up
* A material injustice involving a Federation citizen would occur absent the interference
* Compliance with specific (and valid) orders that could not be followed if the Prime Directive fully applied (e.g., ancillary to a war with the Federation; first contact missions; diplomatic missions; trade negotiations)
* The society hails or attacks a Federation vessel
* Rescue missions
* The society is in diplomatic discussions with the Federation
* The society was previously interfered with by Federation citizens, whether or not in violation of the Prime Directive (e.g., prior to the Prime Directive being in force; accidental interference).
* The society was previously interfered with by non-Federation citizens (e.g., Klingons) in a manner that would have violated the Prime Directive had it been done by Starfleet personnel
* The society had been contacted by Starfleet but, upon recommendation by the contact/survey team, the planet was nonetheless subject to the Prime Directive as though such contact had not occurred.

There are, however, two circumstances where the Prime Directive is suspended in its entirety. The first is when the ''[[Omega Directive]] '' applies. Due to issues of security only Starfleet officers ranked [[captain]] and above are privy to knowledge of this directive. The existential threat to interstellar society of the dangerous [[Omega molecule]], which destroys subspace and renders warp travel impossible if destabilised, outweighs the philosophical aspirations of the Prime Directive. As a result, during periods when the Omega Directive is operative the Prime Directive is fully suspended for the purpose of rendering harmless any Omega molecules and the ability to create them. The second circumstance is [[General Order 24]]. That order permits a starship captain, in certain circumstances, to destroy the entire surface of an inhabited planet and thereby eradicate any societies living there.

Federation citizens do not need an exception as the Prime Directive does not apply to them. In fact, under the rules as defined in the Directive in the 24th Century, a Starfleet crew is forbidden from forcibly removing Federation citizens from a world, even if they had intentionally and materially interfered with the culture of a world in a way that would otherwise have been prohibited by the Prime Directive.

==Attitudes Toward the Prime Directive==
:"''The Prime Directive is not a matter of degree. It is an absolute.''"
:: - '''Lt. Worf'''

:"''Well, I refuse to be bound by an abstraction. The lives of the people of Boraal are far more important to me.''"
:: - '''Nikolai Rozhenko'''

:"''This is how it begins. All it takes is for one impressionable youngster to join Starfleet, and the next thing you know, a whole generation of [[Ferengi]] will be quoting the Prime Directive and abandoning the pursuit of [[latinum]]. It's the end of Ferengi civilization as we know it and it's all your fault.''"
:: - '''Quark'''

Starfleet as an organisation has the greatest respect for and requires compliance with the Prime Directive. But not all Federation citizens, or even all Starfleet personnel, believe that strict adherence to the Prime Directive under every circumstance is in the best interests of the civilisations it was designed to protect. Starfleet captains themselves have very different personal tolerances for the degree of flexibility to be applied to the Prime Directive. Captain [[memoryalpha:James T. Kirk|James T. Kirk]] noted that the Prime Directive was intended to apply only to living, growing civilisations and felt it was appropriate to interfere where societies had been enslaved or were in a state of total stagnation (also known as an arrested culture). Captain Kirk also at least once attempted to interfere in the internal affairs of a civilisation when he believed that higher ethics compelled or justified such actions. On the other hand, both Captains Picard and Janeway were prepared to watch whole societies perish from natural causes rather than interfere &ndash; even when others were seeking to prevail upon them that Starfleet's role should permit actively saving societies rather than passively watching them die. This range of conduct could even be found within a single individual: Captain Kathryn Janeway once noted that [[23rd century]] Starfleet officers such as Kirk were "a little too slow to invoke the Prime Directive," but she herself admitted to having "bent it on occasion" during her travels in the [[Delta Quadrant]].

The Prime Directive as a general prohibition against interference is unique to the [[United Federation of Planets]]. Other organisations and cultures outside of the Federation have different approaches to matters regarding interference with societies. These range from total annihilation of civilisations through assimilation (for example, the [[Borg]]), to planetary relocation when the society was endangered on its homeworld (for example, the [[memoryalpha:Preservers|Preservers]]), to providing advanced knowledge on an ''ad hoc'' basis when the society was deemed ready (for example, the [[Vulcan]]s), to interfering whenever doing so was seen as vaguely amusing (for example, the [[Q]]).

==Examples==
There are many examples of actions during the 23rd and 24th Centuries that were either identified at the time as violations of, or could appear to have potentially been violations of, the Prime Directive.

===Interference with Societies Unaware of Other Worlds===
* In 2266, Captain Kirk took a landing party down to a remarkably Earth-like planet in response to a general distress call. Once there, he and the rest of the landing party became infected with a virus that killed adults, but significantly slowed the ageing process of those who had not yet entered puberty. Dr. Leonard McCoy discovered a cure for the virus, which was also given to the few children who remained alive on the planet and with whom the landing party had interacted.
* On stardate 3156.2, the USS ''Enterprise'' was trying to determine the fate of the starship ''Archon''. After his entire crew was threatened with death by the Landru computer, Captain Kirk caused the computer to self-destruct by convincing it that it was harming the society that it was designed to protect. Kirk justified the interference by claiming that the society was not "a living, growing culture" and that as an arrested culture the Prime Directive did not apply to it. Following the destruction of the computer Kirk left behind a team of specialists to assist the planet with societal development in the absence of Landru.
* On stardate 3715.3, Kirk ordered the ''Enterprise'' to destroy the Vaal computer that was caring for the inhabitants of Gamma Trianguli VI. Doing so saved his ship from destruction after the Vaal computer attacked the vessel. Kirk justified his action on the grounds that the people on the planet were essentially enslaved by a computer. As Kirk said at the time, "These people aren't living. They're existing. They don't create, produce, even think. They exist to service a machine... we owe it to them to interfere."  Despite serious misgivings from his [[First Officer]] Spock about his rationale, Kirk decided that the society was &ndash; as were the followers of Landru &ndash; an arrested culture and therefore not subject to the Prime Directive's prohibitions.
* On Stardate 2534.0 the crew of the ''Enterprise'' investigated the loss of contact with historian and cultural observer, John Gill, who had been assigned to the planet Ekos. They discovered that Gill deliberately violated the Prime Directive in an attempt to reorder the planet's society into a benign version of Nazi Germany. Captain Kirk acted to reduce the effects of Gill's interference in the hopes of restoring the peace that had existed before Gill's arrival. Kirk's corrective interference resulted in the overthrow of the planetary government Gill had installed and allowed for a return to such peace.
* In an attempt to gain diplomatic alliances and hide their activities, the Klingons surreptitiously introduced advanced (for the planet) weapons to enemies of the Hill People on the planet Neural. Their belief was that once the Hill People were obliterated the planet would ally itself with the Klingon Empire. Discovering the interference on stardate 4211.4, Kirk felt that it was justified to "even the odds."  Through corrective interference intended to eliminate the advantages introduced by the Klingons, Kirk decided to provide the Hill People similar weapons.
* In 2268, Captain Ronald Tracey of the USS ''Exeter'' provided material support to one faction on planet Omega IV in their ongoing war with a rival faction. He did so primarily through strategic advice and extensively using his phaser during at least one battle otherwise fought with bladed weapons, spears, and arrows. Tracey's rationale for violating the Prime Directive was that he believed the planet was the source of a means for Humans to significantly extend their lifetimes; he saw protection of the Kohms as the best way to allow scientific study of that means. His conclusion was that the benefits of general life extension throughout Humankind outweighed his significant interference in the planet's society. (This was echoed a century later by a similar rationale used by [[Admiral]] Matthew Dougherty in his dealings with the Ba'ku.) Tracey was subsequently arrested by Captain Kirk for his violation.
* On stardate 4842.6, Captain Kirk inadvertently became entangled with the native population of the planet Amerind after his memories were damaged by an alien device. He was proclaimed a god by the indigenous population of Native Americans, married the daughter of the chief, and fathered a child with her before having his memory restored. He was later rescued by Commander Spock and Dr. McCoy, who were also inadvertently seen in full uniform by the indigenous people.
* Also in 2268, the USS ''Enterprise'' discovered the wreckage of the SS ''Beagle'' near planet 892-IV. A merchant service vessel, the ship and its captain, R.M. Merik had been missing for six years at that time. Upon finding the planet Merik had been convinced that carrying knowledge of the planet elsewhere would damage the highly traditional society there; he and his crew therefore beamed down to live within the society. By the time the ''Enterprise'' arrived, Merik had been elevated to First Citizen, an influential leader within the society. Captain Kirk considered Merik's interference to have violated the Prime Directive, but Merik died before he could be charged or exonerated. During this mission Kirk provided a special commendation to Montgomery Scott as "Despite enormous temptation and strong personal feelings, he obeyed the Prime Directive. His temporary blackout of the city below resulted in no interference with the society and yet saved the lives of myself and the landing party."
* In 2365, [[Lieutenant Commander]] Data answered a call for help from Sarjenka of Drema IV and maintained communication with her for eight weeks. Her planet was undergoing extreme seismic disturbances that the USS ''Enterprise''-D could potentially correct. A highly emotive discussion took place among the senior staff on whether or not to interfere by resolving the problems on the planet, with mixed views on the application of the Prime Directive. The matter was settled after Captain Picard declared that the request for help allowed for an exception. Data later transported Sarjenka to the ''Enterprise'' to save her life, but her knowledge of the ship and of Data was erased from her memory. The ''Enterprise'' neutralized the seismic activity of the planet without the inhabitants being aware of it, thereby answering the call for aid while minimally interfering with the society.
* A malfunction in an observation team's duck blind (a holographic projection to hide a Federation cultural observation post) in 2366 caused an explosion which was viewed by the people of Mintaka III. Despite multiple attempts by the crew of the ''Enterprise'' to eliminate the societal interference (including memory wipes and secret infiltration into the society), the result of this caused the Mintakans to revert into a religious belief in an Overseer (a god). The Mintakans had previously been on a social trajectory that included a rejection of religion, so in a final attempt to correct the inadvertent interference Captain Picard purposefully revealed aspects of the Federation to the leader of the Mintakans. This revelation showed that none of the crew were supernatural, and &ndash; while some limited knowledge of other worlds and societies remained &ndash; the corrective interference by Picard was intended to cause the Mintakans to return to their societal development as before.
*In 2370 Nikolai Rozhenko was acting as an assigned cultural observer for a pre-warp society on Boraal II. During and after his assignment he committed at least three actions which had Prime Directive implications. First, he intervened to save a village of people on Boraal II from the destruction of their planet from natural causes (in direct contravention of Captain Picard's orders regarding the use of his ship for such purposes). Second, he fathered a child with a native of Boraal II. Third, he elected to remain with the village following its resettlement to Vacca VI. Rozhenko's plan to save the village was to transport the entire population to a holodeck on the ''Enterprise''. He then intended to mask their relocation and knowledge of the Federation by using holodeck technology, thereby (in his opinion) acceptably minimizing the interference in their society while they were relocated to a different planet. Captain Picard disagreed with taking any action as saving the village from a natural disaster was in his opinion a Prime Directive violation. When presented with Rozhenko's ''fait accompli'' of having already transported the village to the ''Enterprise'' as Boraal II was dying, Picard chose to resettle the village on Vacca VI while simultaneously trying to minimize the societal interference (although one native of Boraal II committed suicide after he inadvertently discovered what was happening to his people). Rozhenko was later permitted to remain on Vacca VI following the successful resettlement of the village by the ''Enterprise''.   
* In 2371, Captain Janeway and Lieutenant Paris both inadvertently interfered in a society on a class M-Planet in the Delta Quadrant and acted to repair that interference. While investigating a massive, planet-wide explosion that caused subspace to be ripped into many fractures, Janeway and Paris were transported a day back in time through one such fracture. In one alternate timeline the subsequent efforts by the crew of the starship ''Voyager'' to rescue them caused the explosion that destroyed the surface of the planet. In another timeline Janeway recognised the danger presented by the rescue attempt and prevented the crew's inadvertent interference from triggering the explosion. The latter timeline became the primary one such that the society was not interfered with in any respect.
*In 2379 the inhabitants of Kolarus III lived in isolated pockets in a pre-warp civilization at an early stage of industrial development. Captain Picard, Data, and Worf were investigating positronic signatures on the planet's surface when they were unexpectedly attacked by a group of inhabitants. An ion storm had previously prevented them using the ship's transporters, and so the away team had landed in the shuttlecraft ''Argo'' and were using its all-terrain vehicle to collect what turned out to be scattered portions of B4. The away team responded to the attack with suppressing phaser fire and a rapid escape. This display of weaponry, the vehicle, the crew (in uniform), and the ''Argo'' itself were all observed by the inhabitants, whose memories were left intact.

=== Interference with Societies Aware of Other Worlds===
* In 2267 Captain Kirk severely damaged a computer system on Eminiar VII. The system was used in conjunction with a Vendikar computer system to simulate war between them (rather than truly wage it). Damaging the system abrogated a treaty between the two worlds and gave the planets the choice of either waging real war or agreeing to cease hostilities. Eminiar VII, for its part, attempted to choose the latter course with the help of a Federation ambassador. The interference occurred during diplomatic discussions with the Federation, and was ancillary to Kirk's invoking [[General Order 24]].
* Later in 2267, Kirk persuaded Spock's mirror double to work for significant cultural change in the [[Terran Empire]]. Had the actions occurred in the Federation's universe they would undoubtedly have constituted interference in the internal affairs of other societies. However, applicability of the Prime Directive to another universe had not previously been required to be contemplated as such universes were only theoretically believed to exist.
* During a Starfleet-ordered contact to open negotiations with the Capellans for mineral resources on stardate 3156.2, Captain Kirk prevented the Teer (leader) of certain tribes from killing the wife and unborn child of the former leader. This delay resulted in her giving birth to a child who was, by lineage, to be a future leader of the tribes. The actions were a counter-response to the overthrow and death of the legitimate leader due to Klingon influence. Since the deposed leader would otherwise have remained in power absent the Klingons, actions to preserve his lineage were an attempt to "repair" the society.
* In 2319, then [[Captain]] Mark Jameson of the USS ''Gettysburg'' supplied weapons to the leader of one faction, Karnas, on Mordan IV in exchange for the release of Federation hostages. However, he also supplied Karnas' rival factions with equivalent weaponry. The net result was the affected society was plunged into decades of civil war. His rationale, later given to Captain Jean-Luc Picard, was that arming both sides was intended to maintain a balance of power, save the hostages, and negate his interference. (Jameson, however, also mentioned that he falsified records of this event to [[Starfleet]] indicating his confidence in the validity of his excuse was not as high as he later claimed.) Jameson died prior to any action being taken as a result of his interference becoming known, although Picard had previously expressed sympathy for the result of his actions, arguing that Karnas could have chosen to work for peace rather than continue his vendetta.
* Captain Picard interfered with the Edo society of Rubicun III on stardate 41255. First, he prevented the lawful execution of a Federation citizen (Wesley Crusher) for having inadvertently disturbed some new plantings. Second, while questioning a representative of the Edo regarding an investigation into what a powerful alien ship might do should he prevent the execution, Picard revealed that the Edo's god was an orbiting installation. Picard justified his actions to Starfleet by claiming that the execution &ndash; the sole punishment of the Edo for unlawful activity &ndash; would result in such a material injustice to Wesley that the interference in the internal affairs of the Edo was justified.
* In 2369, Chief Miles O'Brien took actions on station Deep Space 9 which interfered in the progression of a "hunt" between a group of Hunters and their quarry, a Tosk. The hunt was culturally significant to their society, and interference in the hunt was deemed by the station's commanding officer, [[Commander]] Sisko, to represent a violation of the Prime Directive. Sisko remarked that an exception permitting the interference would have existed had the Tosk affirmatively requested asylum from the Federation, but the Tosk considered such a request shameful. O'Brien's actions to nevertheless help the Tosk escape from the Hunters earned him a reprimand in his Starfleet record- although he justified his actions as restoring the hunt to its original level by allowing Tosk and the Hunters to continue as though they'd never come to DS9- even though Sisko privately sympathised with his motives and may have been complicit in O'Brien's aid.
* Also in 2369, Commander Sisko offered to remove the Ennis and the Nol-Ennis from their moon prison. Dr. Julian Bashir suggested that doing so might amount to a "jail break," thereby interfering with their society's administration of justice. Sisko replied that as the commanding officer he believed the Federation would consider the artificial microbes infused into the prisoners' systems sufficient for them to be seen as "separate and unique" from their original society. This would make the Prime Directive inapplicable. It remained a theoretical discussion, as no one was removed from the prison.
* In 2371 (Stardate 48315.6), Captain Kathryn Janeway destroyed the Caretaker's array. This was done after the Caretaker had, as he was dying, initiated a self-destruct program. The Caretaker's reason for destroying the array was to prevent the Kazon from using it against the Ocampa &ndash; a race the Caretaker was nurturing and protecting. That program malfunctioned due to a Kazon ship colliding with the array following a battle with the ''Val Jean''. Lieutenant Tuvok advised Janeway of the potential Prime Directive issues of becoming involved in internal societal matters when he said that destroying the array "would affect the balance of power in this system. The Prime Directive would seem to apply."  However, because the Kazon ship would not have collided with the array but for the unintended arrival in the system of ''Voyager'' and the ''Val Jean'', Janeway's destruction of the array was a corrective action that reinstated the Caretaker's self-destruct plan. Her actions therefore reinstated events that would have occurred absent ''Voyager''{{'}}s forcibly becoming involved.
* In 2372, Lieutenant Torres assisted the Pralor Automated Personnel Units (APU) in developing a way to reproduce themselves. When first encountered by ''Voyager'' the Pralor APUs were found to be designed such that they could not create additional APUs. Torres had argued to Captain Janeway that helping the APUs to work around that design would "save them from extinction" since over time the APUs were becoming non-functional (either through age, accident, or war). Janeway refused, likening the modified design under consideration to being the "equivalent of altering their genetic structure," and therefore a Prime Directive violation. Saying that "extinction is often the natural end of evolution," Janeway refused to permit Torres to continue. The APU later kidnapped Torres and forced her, under duress, to develop a prototype that could serve as the new design standard and permit reproduction. Prior to her rescue Torres destroyed her work (in part because of revelations that the new design would be used primarily to gain advantage in a war). This action denied the APUs access to her design changes and eliminated the interference.
* In the early to mid 2370s, Captain Rudolph Ransom and the crew of the USS ''Equinox'' killed multiple nucleogenic lifeforms and used their bodies for fuel to greatly enhance their warp drive. Ransom felt that he was justified under [[Starfleet General Orders and Regulations#Starfleet Regulations|Starfleet Regulation 3]], which provided that "in the event of imminent destruction, a Captain is authorized to preserve the lives of his crew by any justifiable means."  Captain Janeway rejected this reasoning, and declared his systematic murder of members of an alien society to be a direct violation of the Prime Directive. Ransom, preferring to fight both ''Voyager'' and the nucleogenic lifeforms than spend "thirty years in [the] brig," was eventually killed himself when the ''Equinox'' was destroyed by the aliens he had been killing.
* In 2374, Captain Benjamin Sisko worked with Elim Garak to force the Romulan Empire to enter into the [[Dominion War]] under false pretences. The Romulans up to that point had remained neutral in the conflict. Sisko and Starfleet felt that Federation and Klingon Empire would lose the war with the Dominion if they did not gain another ally. Both Sisko and Garak, with the knowledge and approval of [[Starfleet Command]], created false evidence that ultimately convinced the Romulans that the Dominion was planning to renege on the Peace Treaty between the two governments and mount a full scale invasion. Participation in the war by the Romulans resulted in massive military and civilian casualties within Romulan society.
*Worf challenged and killed Gowron, Chancellor of the Klingon Empire in 2375. Worf's motive was he believed that Gowron was deliberately mishandling Klingon forces in an attempt to destroy the reputation of General Martok, thereby risking the entire war effort against the [[Dominion]] for personal political gain. Due to this Worf had previously been authorised by Captain Sisko to use whatever means were necessary to resolve the issue. Worf defeated Gowron in single combat, and for a few moments was hailed by the assembled Klingons as Chancellor of the Klingon Empire. However, he immediately abdicated in favour of Martok, who assumed the mantle. Prior to the duel Worf removed his combadge and indicated that he was not acting as a Starfleet officer but rather simply as a Klingon.
* Also in 2375, Tom Paris attempted to influence the government of the Monean World Ocean to take more aggressive action to save their water-world from dissipation into space. When Paris proposed that some kind of direct interference take place to cause an otherwise recalcitrant Monean government to act, Captain Janeway declared that such interference with the internal workings of a government to be a violation of the Prime Directive. She thereafter forbade Paris from taking any such actions. Paris nonetheless attempted to destroy an oxygen refinery to demonstrate the dangers of continuing to operate them as the Moneans had been doing. His attempt was thwarted by ''Voyager'', though. As a result Paris was demoted to the rank of Ensign and incarcerated in ''Voyager''{{'}}s brig for thirty days for insubordination, unauthorized use of a spacecraft, reckless endangerment and conduct unbecoming an officer.
*Finally in 2375, [[Admiral]] Matthew Dougherty, acting on orders from the [[Federation Council]], formed an alliance with the Son'a to forcibly relocate the entire Ba'ku population (approximately 600 individuals) from their planet. This was intended to permit Son'a technology to collect metaphasic particles from the planet's rings and was required as the planet would become uninhabitable for decades after the life-extending particles were collected. Dougherty's rationale for interfering with the Ba'ku was that the Prime Directive simply did not apply. He stated that since the Ba'ku were not indigenous to the planet and that they "were never meant to be immortal," that removing them would simply be restoring their natural evolution. Dougherty's true motivation, however, was that collection of the particles could double lifespans throughout the Federation and that an entire new medical science would evolve as a result. Captain Picard did not accept this reason for an exception to the Prime Directive. He instead believed that Starfleet's participation in a forced relocation of a society would be "an attack on the very soul of the Federation."  Picard therefore disobeyed Dougherty's direct orders, conspired with fellow crew members to commit an armed insurrection against the Admiral and his allies, and was threatened with a court martial when captured. Picard believed his refusal to accept orders that voided the Prime Directive was justified and that if "a court martial is the only way to tell the people of the Federation what happened here, then I welcome it."  Picard's actions ultimately prevented the relocation of the Ba'ku and did not result in either his loss of rank or command.

==Other Notable Matters==
* The Prime Directive did not go into effect as a General Order until sometime after the 2160s (which is when the crew of the starship ''Horizon'' left behind books on technology and culture that radically altered the course of civilization on the planet Sigma Iotia II.)
* While the Prime Directive was not officially formulated until after the 2160s, the fundamental principles were an important part of [[Earth]] [[Starfleet]] procedures as early as 2152.
* On stardate 43775.5, the USS ''Enterprise''-D received a mission order from an [[admiral]] at [[Starfleet Command]]. According to the mission specifications, contact with the living spacecraft code named "Tin Man" were to include considerations for the Prime Directive.
* Benjamin Sisko and his crew on Deep Space 9's orders were "to do everything short of violating the Prime Directive" to make [[Bajor]] and the [[Bajoran]] people ready for Federation membership.
* A related order, known as the [[Temporal Prime Directive]], was also created, mainly applicable to Starfleet officers time-travelling to the past. It prohibited them from interfering with past events, thereby altering the course of history; this included giving information about future events to individuals in the past.
* According to Rear Admiral Norah Satie on stardate 44769.2, Jean-Luc Picard had violated the Prime Directive a total of nine times since taking command of the USS ''Enterprise''-D three and a half years prior.

In the TNG novel ''Double Helix: ''Double or Nothing'' the ''Resolution of Non-Interference'' was drafted and signed by all Federation members in 2175. By the 2190s the ''Prime Directive'' was in full force.

In the TOS novel ''Prime Directive'', a ''Scale of Culture'' was developed in the early 2200s in order to measure cultural development of a civilization and monitor its development.

According to the CD-ROM game ''Star Trek: 25th Anniversary'', one of the most serious violations of the Prime Directive was an event known as "The Galahad Incident" caused by an unauthorized entry of the USS ''Galahad'' into the civil war on Shiva Omicron IV in 2208. The ''Galahad'' used its phasers to stun an army of the Jerion faction during an attempted massacre, causing the unconscious Jerions to be themselves massacred. This eventually led to the destruction of the Jerion culture. This event became a test case for measuring the competency of a starship captain. Captain Joshua Mulrone Grant was court-martialed and imprisoned for his part in the genocide. At his court martial, he stated, "''the Human Directive is the real Prime Directive.''"
