- These do not appear to have been formal law.
Following the Time Lord-Vampire War (TV: State of Decay), the Time Lords abandoned the use of violence, but still continued to involve themselves in the affairs of the wider universe. This had catastrophic results for the people of the planet Minyos whom they gifted with high technology. The Minyans regarded the Time Lords as god-like beings.
As a result of being granted technology they did not have the cultural maturity to use responsibly, nuclear war broke out on Minyos and the Minyans were nearly made extinct. The Time Lords left Minyos at around the same time. (TV: Underworld)
Horrified by the results of their meddling, the Time Lords adopted a strict policy whereby they would only observe the events of the wider universe, and never become involved personally. (TV: Underworld)
Time Lords appeared to have been mentally conditioned against interfering in history. Challenging this rule could result in memory loss, shutting down whole aspects of personality, and madness. (PROSE: Time and Relative)
Like many of their principles, the Time Lords' attitude to the non-interference policy was somewhat flexible, even to the point of hypocrisy. During the Millennium War, Rassilon broke the policy and joined the fight against the Mad Mind of Bophemeral. (PROSE: The Quantum Archangel) Before the Doctor's departure he was able to make the Time Lords implement a ban on miniscopes, an act which earned him great respect in the wider universe. (TV: Carnival of Monsters) It was the Time Lord Irving Braxiatel who organised the Armageddon Convention, which led to the banning of many weapons of mass destruction amongst leading civilised species. (PROSE: The Empire of Glass)
The Time Lords later breached the policy on a major scale; after beings from the constellation of Andromeda were able to infiltrate the Matrix and steal its secrets, they devastated the planet and moved it light-years across space to conceal what they had done and prevent the secrets reaching Andromeda. They also manipulated events and individuals on Thoros Beta to prevent Crozier from discovering an effective means of immortality. (TV: The Mysterious Planet, Mindwarp) The Doctor eventually discovered what had happened to Earth but was unaware of the reasons. Apparently fearing his reaction, the Time Lords put him on trial for his life, the initial pretext being (ironically enough) his repeated breaches of the policy. (TV: The Trial of a Time Lord)
At the pleading of Clara Oswald, the Time Lords broke the policy to save the Doctor's life. He was destined to die in battle on Trenzalore due to lacking the ability to regenerate once more. The Time Lords sent the Doctor a new cycle of regeneration through a crack in time, allowing him to defeat the Daleks and become the Twelfth Doctor, changing his personal future and the future of Trenzalore which had changed from a planet with life and a farming village to a massive battlefield graveyard with millions of people buried in the now-alternate timeline where the Doctor died. (TV: The Time of the Doctor)
The Doctor Edit
It was partly the non-interference policy which led to the First Doctor leaving Gallifrey. He felt that there were evils which should be fought, and positive ways of interfering. Additionally, he claimed he was bored at home and wanted to experience the universe first hand. When the Time Lords eventually located him in his second incarnation, he was put on trial for breaching the policy.
In defending his actions, the Doctor managed to convince the Time Lords that there was some merit to his argument of justifiable interference. An ironic result of this was that the Time Lords punished the Doctor for repeatedly involving himself in the affairs of less-advanced planets by involving him in the affairs of a less-advanced planet for an extended period of time: they exiled him to Earth in the 20th century with his TARDIS rendered inoperative. (TV: The War Games)
The Time Lords repeatedly demonstrated a willingness to involve themselves in the affairs of the universe, using the Doctor as an unofficial (and frequently unwilling) agent. For a considerable period of time they used his talents to further their own agenda:
- The Second Doctor appears to have carried out a series of missions for the Time Lords. (TV: The Two Doctors, PROSE: World Game, etc)
- The Time Lords sent the Third Doctor to Uxarieus to stop the Master gaining control of the Doomsday Weapon, (TV: Colony in Space) to Solos to help the natives complete their natural metamorphosis, (TV: The Curse of Peladon) and (probably) to Peladon to help the planet's bid to join the Galactic Federation. (TV: The Mutants) All of these occurred prior to the formal lifting of the Doctor's exile.
Following the lifting of the exile it was harder to tell which of the TARDIS' unplanned landings were a result of Time Lord intervention and which were simply caused by poor piloting. It is known that at some point they installed a remote operation module, which allowed them to surreptitiously control where the TARDIS went. They found the Doctor would make the right decision when he believed he was there by choice. (AUDIO: No Place Like Home)
- The Time Lords appeared to have helped the Third Doctor pursue the Daleks to Spiridon. (TV: Frontier in Space, Planet of the Daleks)
- A Time Lord appeared to the Fourth Doctor in person at the start of his mission to Skaro to avert the creation of the Daleks (a mission to ultimately have dire consequences for the Time Lords). (TV: Genesis of the Daleks)
- The Doctor believed his arrival on Karn was the result of Time Lord interference. The presence on the same planet of the remnants of the renegade Morbius would seem to suggest he was correct. (TV: The Brain of Morbius)
- Much later, the Sixth Doctor believed his involvement in the Cybermen's attempt to destroy Earth in 1985 was a result of Time Lord machinations. (TV: Attack of the Cybermen)
Some of these missions (or perhaps all) may have taken place under the auspices of the Celestial Intervention Agency, a shadowy Gallifreyan faction who took a particular interest in the Doctor. (TV: The Deadly Assassin)
The full extent of the CIA's activities were unknown, and individual Gallifreyan attitudes to the policy varied - Rodan appeared to regard it as inviolable, whereas Romana I accepted being asked to leave Gallifrey and assist the Doctor. (TV: The Invasion of Time, The Ribos Operation)
Breaking of the policy Edit
The Time Lords, in order to survive the Time War, decided to make the biggest break of the policy: destroy the universe in order to survive as beings of pure conciousness, a plan devised by Rassilon himself. The Tenth Doctor stopped them with the help of his companion Wilfred Mott and the Master. In this instance, the Doctor banished the Time Lords back into the War to die and also prevented numerous other threats from coming through that would have turned the universe into hell, as the Time War was. (TV: The End of Time) However, Gallifrey was never destroyed, only frozen in a moment and placed in another dimension. (TV: The Day of the Doctor)
