Metalaw
Metalaw is “the entire sum of legal rules regulating relationships between different races in the universe.” It is a concept of space law closely related to the scientific Search for Extraterrestrial Intelligence (SETI). The idea is an elaboration of Immanuel Kant's Categorical imperative "Act only according to that maxim whereby you can at the same time will that it should become a universal law." == Andrew Haley and the origin of Metalaw == First articulated by attorney Andrew G. Haley in 1956, Metalaw was the term Haley coined to refer to his hypothesis regarding the proposed existence of fundamental legal precepts of theoretically universal application to all intelligences, both human and hypothesized intelligent extraterrestrial life.
