[N.B.: this article is frequently mis-cited as being published in the Harvard Law Review, and academic legal journal] [This article was also re-published as an addendum to the Proceedings of the Fourth Colloquium on the Law of Outer Space held in 1961 and published by the International Institute of Space Law of the International Astronautical Federation in 1963-- this is probably easier to locate in libraries than the Harvard Law Record, which was the student newspaper of the Harvard Law School]

What is Metalaw?
According to Dr. Ernst Fasan, Metalaw is “the entire sum of legal rules regulating relationships between different races in the universe.” Metalaw is the “first and basic ‘law’ between races” providing the ground rules for a relationship if and when we establish communication with or encounter another intelligent race in the universe. Dr. Fasan envisioned these rules as governing both human conduct and that of extraterrestrial races so as to avoid mutually harmful activities.
