In the United States Supreme Court case of The United States v. Domingo Acosta, the court was asked to decide whether a Spanish subject who had been living in Florida since before it became part of the United States could be considered an American citizen and thus entitled to bring suit against another person in federal court. At issue was whether or not someone born outside of the US but residing within its borders at the time that it gained control over those lands should be granted citizenship rights under naturalization laws. The Supreme Court held that such persons were indeed citizens and therefore allowed them access to federal courts for their legal disputes with other individuals. This ruling established a precedent which has been used ever since as a basis for granting citizenship status to people from foreign countries who have lived within US boundaries prior to their acquisition by America.

In the case of United States v. Domingo Acosta, the Supreme Court was asked to decide whether a Spanish grantee could be held liable for taxes on land he owned in Florida. The majority opinion found that since Spain had ceded control over Florida to the United States, and since Congress had not yet passed any laws regarding taxation of such lands, Acosta did not have to pay taxes on his property. However, Justice McLean dissented from this decision and argued that although no law existed at the time requiring payment of taxes by Spanish grantees like Acosta, it would still be reasonable for them to do so given their status as citizens or residents of a foreign country who were now living within U.S. borders and enjoying its benefits without contributing financially towards those same benefits through taxation. He further argued that if they were allowed to avoid paying these taxes indefinitely then it would create an unfair situation where other taxpayers would have an increased burden due solely because some individuals chose not to contribute their fair share when they should have done so under existing circumstances
