evidence: Serranilla Bank was first shown on Spanish maps in 1510. It is administered by Colombia as part of the department of San Andrés and Providencia.[3][4] The reef is subject to a sovereignty dispute involving Colombia and the United States. A previous claim by Honduras was resolved in favor of Colombia when the two countries approved a treaty establishing their maritime boundaries.[5] Jamaica's claim was resolved when it established a joint regime area with overlapping maritime boundaries in 1993, but acknowledging Colombian control of Serranilla and Bajo Nuevo banks.[6] In 2012, in regards to Nicaraguan claims to the islands, the International Court of Justice (ICJ) upheld Colombia's sovereignty over the bank, although the judgment does not analyze or mention the U.S. claim over the reef.[7] [...] - ^ (in Spanish) Treaty of exchange between Colombia and the United States, 1972 Archived 2011-05-24 at the Wayback Machine - ^ "Application of the U.S. Constitution" (PDF).
