After retaking the state legislatures of New Jersey and Ohio, Democrats rescinded their ratifications. On July 20, 1868, Seward certified that if rescissions are invalid, the amendment became law with South Carolina's ratification as the 28th state.[112] The following day, Congress rejected New Jersey's rescission as "scandalous", declaring the Fourteenth Amendment as part of the Constitution and directing Seward to promulgate it as such, establishing that states cannot rescind their ratification:[113][112]
- Alabama: July 13, 1868
- Georgia: July 21, 1868 (after rejection November 9, 1866)
Upon receiving Georgia's ratification on July 27, Seward officially proclaimed the Fourteenth Amendment's adoption, listing all thirty ratifying states to prevent federal courts from recognizing rescission.[112] On October 16, 1868, three months after adoption, Oregon rescinded its ratification, but this had no impact on Fourteenth Amendment's validity. The Fourteenth Amendment was subsequently ratified by the following states:[111]
- Virginia: October 8, 1869 (after rejection January 9, 1867)
- Mississippi: January 17, 1870
- Texas: February 18, 1870 (after rejection October 27, 1866)
