The Executors and Heirs of Augustin de Yturbide, Deceased, Appellants v. The United States was a case heard by the Supreme Court in 1859. At issue was whether or not the executors and heirs of Augustin de Yturbide were entitled to compensation for land that had been taken from them by the United States government without just compensation. The court held that they were not entitled to such compensation because it would be an unconstitutional taking under the Fifth Amendment's Takings Clause. Furthermore, since there was no contract between Yturbide's estate and the US government regarding this matter, any claim for damages could only be made through a suit at law rather than equity. This decision established precedent which has been used in subsequent cases involving takings claims against governments around the world.

In this case, the Executors and Heirs of Augustin de Yturbide argued that they were entitled to a large sum of money from the United States for land in Texas which had been granted by Mexico prior to its annexation. The Supreme Court disagreed with their argument, finding that under Mexican law at the time, no title could be acquired until after an official grant was issued by a competent authority. As such, since there was never any such grant issued before Texas became part of the United States, no valid claim existed on behalf of Yturbide's heirs. Furthermore, even if it had been possible to acquire title under Mexican law prior to annexation as claimed by Yturbide's heirs, it would have still been subject to confirmation or rejection upon review by Congress following annexation - something which did not occur here either. Therefore, because there was no valid claim established under either Mexican or American law in this case due to lack of proper documentation and approval from relevant authorities at both times during transition between countries' sovereignty over Texas territory ,the Supreme Court found against Yturbide's heirs and upheld previous decisions made in lower courts denying them compensation for their alleged loss.
