Lerdo ran for a second term in 1876, which gave opponents the grounds to oppose him on the principle of "no reelection." At this point, Porfirio Díaz, who had been neutralized politically with his unsuccessful revolt against Juárez in 1872, now believed he had the grounds to challenge Lerdo, which were articulated in the Plan of Tuxtepec. The plan was issued prior to the July 24, 1876 election, which Lerdo won. Some charged that the victory was fraudulent, but perhaps no more so than its predecessors. Lerdo did not muzzle the free press, which printed the accusations and began to call for open rebellion. The President of the Supreme Court, José María Iglesias did declare the election fraudulent, a ruling which put him as successor to the presidency.
