Prime Directive (Core) for easy reference (English)

Mari Swaruu:

Prime Directive

Star Captain's most solemn oath is that he will give his life, even his entire crew, rather than violate the Prime Directive. The Prime Directive is immediately applicable to all cultures on any planet that has not yet achieved warp capability, meaning that they are not yet interstellar. This directive can be found in the Articles of the Federation, Chapter 1, Article 2, Paragraph 7, which states:

"Nothing within these articles of Federation shall authorize the United Federation of Planets to intervene in matters which are essentially the domestic jurisdiction of any planetary social system, or shall require the members to submit such matters to settlement under these articles of the Federation. But this principle shall not prejudice the application of enforcement measures under Chapter 6."

As the right of each sentient species to live in accordance with its normal cultural evolution is considered sacred, no Federation personnel may interfere with the normal and healthy development of alien life and culture. Such interference includes introducing superior knowledge, strength, or technology to a world whose society is incapable of handling such advantages wisely. Federation personnel may not violate this Prime Directive, even to save their lives and/or their ship, unless they are acting to right an earlier violation or an accidental contamination of said culture.

This directive takes precedence over any and all other considerations and carries with it the highest moral and ethical obligation. In other words, the Federation cannot expose an evolving species or culture to technology that the species has not yet discovered or is currently capable of developing.

Not permitted to make contact with or interfere with lesser races unless they are threatened by an outside source. It is forbidden to communicate with any native resident of a lesser developed race and culture with any device, appliance, machine, tool, weapon or invention representing an improvement upon the science and technology already in existence upon their planet.

It is forbidden to present members of any lesser developed race or culture with any kind of proof that would demonstrate the existence of the United Federation of Planets and of their members, including all technological machinery and gadgets of all sort, be them existing ones or future development pertaining to Federation members.

Should the rumor of their existence has spread among the members of said race, they should be quickly suppressed and covered up using any method at the disposal of the Federation's members in order to preserve as much as possible the natural progression of their spiritual, cultural, and technological development as it is considered sacred.
