"Outer space is a legally and physically unique domain of human activity, and the United States does not view it as a global commons." --Executive Order 13914, 6 April 2020
This statement is counter to the theory of the legal status of outer space that has prevailed in academic literature from the beginning of the Space Age. While it is impossible to cite all of the pertinent literature in this venue, let it suffice here to quote Carl Q. Christol 14 INT’L LAW 429, 448 (1980):
“Since Article 2 of the Principles Treaty did not prohibit the private use and exploitation of natural resources, and since one of the purposes of Article I was to allow for the sharing of benefits derived from the exploration and use of the space environment, it may be concluded that private persons were in effect encouraged to engage in private space activities. Such conduct would fit into the expectations fortified by the res communis concept in its joint application to the conduct of States, international organizations, and private natural and juridical persons.”
This quote is singled out because it is quoted by Wayne N. White IAC-03-IISL.2.12 (2003). The cause of private property rights in outer space has no greater champion than in White.
In the speech by Scott Pace referred to by Christopher Stone, we find the following statement:
“Finally, many of you have heard me say this before, but it bears repeating: outer space is not a ‘global commons,’ not the ‘common heritage of mankind,’ not ‘res communis,’ nor is it a public good. These concepts are not part of the Outer Space Treaty, and the United States has consistently taken the position that these ideas do not describe the legal status of outer space.”
Putting aside a presumed obligation to define what a thing is after declaring what it is not, although it is true that the Treaty contains no such language per se, that is not the whole story, and the validity of Dr. Pace’s statement can be tested by examining the Treaty’s travaux preparatoires.
In examining more than sixty documents, I was surprised that I was unable to find any discussion in UNCOPUOS regarding the terms “global commons” or “res communis.” If the Legal Subcommittee rejected a concept that was so prevalent in the academic literature of the time, one would expect a cogent refutation to be reflected in the travaux. It is not, and this being the case, it is more reasonable to conclude that the Subcommittee regarded the concept as customary international law, reflected, in the language of Article 38(d) of the Statute of the International Court of Justice, in “the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.”
Although there was no discussion of the concept, the record does record a single, concise statement:
“The second paragraph of article I of the Soviet draft comprised a provision which expressed the res omnium communis character of outer space and celestial bodies.” (AC105.C2.SR064E).
This uncontradicted statement would not have entered the record had it been objected to by any UNCOPUOS member state, as all of its output was by consensus.
The paragraph in the Soviet draft was:
“Outer space, including the Moon and other celestial bodies, shall be free for exploration and use by all States without discrimination of any kind, on a basis of equality and in accordance with international law, and there shall be free access to all areas of celestial bodies.” (A.6352Rev1E)
This paragraph was carried forward verbatim into the final draft of the Treaty. To parody Senator Howard Baker’s famous question during the 1973 Watergate hearings, what did the United States understand, and when did it stop understanding it? The conclusion is that the United States not only consented to the inclusion of the Soviet text, but that it also understood that the text “expressed the res omnium communis character of outer space and celestial bodies,” as stated in the Subcommittee’s report.
Given that the United States understood this then, how is it that is does not understand it now? Has it reneged? If so, to what advantage? If one subscribes to the views of Christol, White, and dozens of other “most highly qualified publicists of the various nations,” the position that outer space is not a “global commons” and not “res communis” solves no legal problem with regard to the appropriation of extracted natural resources. It may, however, open a can of worms, in that in this light, what can now be the counterargument to the equatorial states' claims in the 1976 Bogota Declaration to their superjacent arcs of geostationary orbit? It would appear that these claims must now be given serious consideration.
