Incorporated vs. unincorporated territories

Pursuant to a series of Supreme Court rulings, Congress decides whether a territory is incorporated or unincorporated. The U.S. Constitution applies to each incorporated territory (including its local government and inhabitants) as it applies to the local governments and residents of a state. The singular incorporated territory (also known as a ''Territory'', distinct from ''territory'') of the U.S., Palmyra Atoll, is an insular part of the U.S. (neither a part of one of the several States nor a Federal district), but is not a possession. In unincorporated territories, "

. Selected constitutional provisions apply, depending on congressional acts and judicial rulings according to U.S. constitutional practice, local tradition, and law. As a result, these territories are often considered colonies of the United States. All modern inhabited territories under the control of the federal government can be considered as part of the "United States" for purposes of law as defined in specific legislation. However, the judicial term "unincorporated" was coined to legitimize the late-19th-century territorial acquisitions without citizenship and their administration without constitutional protections temporarily until Congress made other provisions. The case law allowed Congress to impose discriminatory tax regimes with the effect of a protective tariff upon territorial regions which were not domestic states. In 2022, the United States Supreme Court in '' United States v. Vaello Madero'' held that the territorial clause of the constitution allowed wide congressional latitude in mandating "reasonable" tax and benefit schemes in Puerto Rico and the other territories, which are different from the states, but did not address the incorporated/unincorporated distinction. In a concurrence with the court's overall ruling on the propriety of the differential tax structures, one of the justices opined that it was time to overrule the doctrine of unincorporated territories, as wrongly decided and founded in racism; the dissent agreed with this view.

Supreme Court decisions about current territories

The 2016 Supreme Court case '' Puerto Rico v. Sanchez Valle'' ruled that territories do not have their own sovereignty. That year, the Supreme Court declined to rule on a lower-court ruling in '' Tuaua v. United States'' that American Samoans are not U.S. citizens at birth. The Supreme Court ruled in 2022 in '' United States v. Vaello-Madero'' that Congress is not required to extend all benefits to Puerto Ricans, and that the exclusion of Puerto Ricans from the Supplemental Security Income program was constitutional.


Supreme Court decisions about former territories

Alaska Territory

''Rassmussen'' arose from a criminal conviction by a six-person jury in Alaska under federal law.

Modern Puerto Rico

Scholars agreed as of 2009 in the ''Boston College Law Review'', "Regardless of how Puerto Rico looked in 1901 when the Insular Cases were decided, or in 1922, today, Puerto Rico seems to be the paradigm of an incorporated territory as modern jurisprudence understands that legal term of art". In November 2008, a district court judge ruled that a sequence of prior Congressional actions had the cumulative effect of changing Puerto Rico's status to incorporated. However, in 2022, the United States Supreme Court held that the territorial clause of the U.S. constitution allows wide congressional latitude in mandating "reasonable" tax and benefit schemes in Puerto Rico and the other territories that are different from the states, but the Court did not address the incorporated/unincorporated distinction. As a result, the ''status quo'' remains, so the U.S. government still defines the Commonwealth of Puerto Rico as a U.S. unincorporated territory.

, "Because we don't have political power, because we don't have representatives, osenators, no vote for president, we are treated as an afterthought." Rosselló called Puerto Rico the "oldest, most populous colony in the world". Rosselló and others have referred to the U.S. territories as American "colonies". David Vine of ''The Washington Post'' said the following: "The people of he U.S. territoriesare all too accustomed to being forgotten except in times of crisis. But being forgotten is not the worst of their problems. They are trapped in a state of third-class citizenship, unable to access full democratic rights because politicians have long favored the military's freedom of operation over protecting the freedoms of certain U.S. citizens." In his article "How the U.S. Has Hidden Its Empire", Daniel Immerwahr of ''The Guardian'' writes, "The confusion and shoulder-shrugging indifference that mainlanders displayed oward territoriesat the time of Pearl Harbor hasn't changed much at all. .. aps of the contiguous U.S.give ainlandersa truncated view of their own history, one that excludes part of their country." The 2020 U.S. Census excludes non-citizen U.S. nationals in American Samoa—in response to this, Mark Joseph Stern of ''Slate'' said, "The Census Bureau's total exclusion of American Samoans provides a pertinent reminder that, until the courts step in, the federal government will continue to treat these Americans with startling indifference."
