What was a landmark case regarding the practice of zoning and property rights, Arizona v. United States or Dolan v. City of Tigard ?
Arizona v. United States Arizona v. United States, 567 U.S. ___ (2012) , was a United States Supreme Court case involving Arizona's S.B. 1070, a state law intended to increase the powers of local law enforcement who wished to enforce federal immigration laws. At issue is whether the law usurps the federal government's authority to regulate immigration laws and enforcement. The Court ruled that sections 3, 5(C), and 6 of S. B. 1070 were preempted by federal law, but left other parts of the law intact, including a provision that allowed law enforcement to investigate a person's immigration status.
Bryan v. Kennett Bryan v. Kennett, 113 U.S. 179 (1885), was a United States Supreme Court case in which the Court held that, under the treaty providing for the Louisiana Purchase, the United States would recognize property interests granted by the previous sovereign governments prior to the Purchase, even if the grant had been inchoate or incomplete. The case involved a disputed title to land in the U.S. state of Missouri, which had previously been under the control of Spain and France before being acquired by the United States. In the late 1700s, the government of Spain had made a possibly incomplete grant of the land to a U.S. citizen, Moses Austin. Spain then lost control of the land to France in 1800, who in turn sold it to the United States. A question later arose as to whether Austin had received sufficient property rights from Spain to allow him to mortgage his land in 1818, or whether necessary rights had somehow passed back to the United States government, making the mortgage invalid and voiding subsequent land transfers that occurred pursuant to Austin's defaulting on the mortgage. Under the Court's holding, the incomplete grant to Austin was valid and sufficient to permit the mortgage.
