Texas v. White, 74 U.S. 700 (1869) was a significant case argued before the United States Supreme Court in 1869. The case involved a claim by the Reconstruction government of Texas that United States bonds owned by Texas since 1850 had been illegally sold by the Confederate state legislature during the American Civil War. The state filed suit directly with the United States Supreme Court, which, under the United States Constitution, retains original jurisdiction on certain cases in which a state is a party.
In accepting original jurisdiction, the court ruled that Texas had remained a state ever since it first joined the Union, despite its joining the Confederate States of America and its being under military rule at the time of the decision in the case. In deciding the merits of the bond issue, the court further held that the Constitution did not permit states to unilaterally secede from the United States, and that the ordinances of secession, and all the acts of the legislatures within seceding states intended to give effect to such ordinances, were "absolutely null".
