Galactic law

From Tardis Wiki, the free Doctor Who reference

Galactic Law was the system of law, similar to international law on Earth, held by many interstellar governments in Mutter's Spiral, and enforced by the Judoon. (DW: Smith and Jones)

One important document of Galactic Law was the Shadow Proclamation. (DW: Partners in Crime)

Presumably, the Galactic Charter was also part of Galactic Law. (DW: The Stones of Blood)

Galactic Law said that developing worlds classed as Level 5 planets (such as Earth in the 21st century and earlier) could not be approached for legal matters, so they had no jurisdiction over the planet, and methods such as a H2O Scoop must be used to transport any places required to be visited to neutral territory, such as the Moon. (DW: Smith and Jones)

Seeding life on a Level 5 planet is also against Galactic Law. (DW: Partners in Crime)
