Level 5 planet

A Level 5 planet, also called a level 5 civilization, was a designation used by Galactic Law in reference to certain worlds, with the implication that it referred to relatively primitive planets not yet fully integrated into galactic civilisation. Level 5 planets were protected by various Galactic Laws. (TV: Smith and Jones, Partners in Crime, The Eleventh Hour)
