Facts. Both the United States (P) laid claim to the ownership of the Island of Palmas.
While the U.S. (P) maintained that it was part of the Philippines, the Netherlands (D)
claimed it as their own. The claim of the U.S. (P) was back up with the fact that the
islands had been ceded by Spain by the Treaty of Paris in 1898, and as successor to
the rights of Spain over the Philippines, it based its claim of title in the first place on
discovery. On the part of the Netherlands (D), they claimed to have possessed and
exercised rights of sovereignty over the island from 1677 or earlier to the present.
Issue. Can a title which is inchoate prevail over a definite title found on the
continuous and peaceful display of sovereignty?
Held. (Huber, Arb.). No. A title that is inchoate cannot prevail over a definite title
found on the continuous and peaceful display of sovereignty. The peaceful and
continuous display of territorial sovereignty is as good as title. However, discovery
alone without subsequent act cannot suffice to prove sovereignty over the island. The
territorial sovereignty of the Netherlands (D) was not contested by anyone from 1700
to 1906. The title of discovery at best an inchoate title does not therefore prevail over
the Netherlands (D) claims of sovereignty.
