The Oklahoma Legislature met in special session to grandfather in the grandfather clause. The new law said those who had been registered in 1914 – whites under the old system – were automatically registered to vote, while African-Americans could only register between April 30 and May 11, 1916, or forever be disenfranchised. That law stayed on the books until a Supreme Court ruling in 1939.
