In The United States, Appellant v. The Heirs of F. M. Arredondo and Others, Appellees, the Supreme Court was asked to decide whether a Spanish grant of land in Florida could be confirmed by an American court after Spain had ceded the territory to the United States under the Treaty of 1819. At issue was whether Congress had intended for such grants to remain valid when it passed legislation confirming all existing titles within certain limits in Florida that were acquired before July 17th 1821 or if they should be considered void because they were granted by a foreign government no longer possessing sovereignty over them. Ultimately, Chief Justice Taney ruled that since there was nothing in either international law or public policy which would prevent recognition of these grants as valid titles and since Congress did not explicitly state otherwise when passing its confirmation act; therefore these grants must be recognized as legitimate property rights held by their original owners even though they originated from a foreign power no longer having jurisdiction over them at the time of their confirmation by an American court.

In the United States vs. The Heirs of F. M. Arredondo, and Others, Appellees case, the dissenting opinion argued that Congress had no authority to pass a law granting land titles in Florida to individuals who were not citizens of the United States at the time they acquired their lands from Spain or its colonies prior to 1819 when Florida became part of the Union. According to Chief Justice Taney's dissent, this was an unconstitutional exercise of power by Congress because it violated Article I Section 8 Clause 17 which gave exclusive jurisdiction over such matters solely to state governments and courts within those states' boundaries. Furthermore, he argued that even if Congress did have some authority in this matter due to its implied powers under Article IV Section 3 Clause 2 (the Property Clause), then any grant made by them would be subject only "to such regulations as may be necessary for carrying into effect" what is provided for in said clause; thus making any grants invalid unless approved by both houses of congress first before being issued out as valid titles - something which never happened here with these particular cases since none were ever presented before either house for approval beforehand nor afterwards after they had already been granted out without congressional authorization or oversight whatsoever .
