Limtiaco v. Camacho (2007), 549 U.S. 483, is a case of the United States Supreme Court which handled a complex taxation dispute between two Guamanian politicians—Douglas B. Moylan, Guam's first elected Attorney General, and Felix P. Camacho, then-Governor of Guam—involving the proper interpretation of the Guam Organic Act. Guam, an unincorporated territory of the United States, is governed by this Organic Act, a United States federal law passed in 1950; much case law in the territory is based on its interpretation.
