Meantime the calumnies spread by the enemies of Zumárraga and the partisans of the first auditor had shaken the confidence of the Spanish Court, and he set sail in May 1532 under orders to return to Spain. On his arrival he met his implacable enemy Delgadillo, who, though still under indictment, continued his calumnies. As a result of Delgadillo's charges, Charles V held back the Bull of Clement VII, originally dated September 2, 1530, that would have named Zumárraga bishop. Zumárraga, however, had little difficulty vindicating his good name, and was consecrated bishop at Valladolid on April 27, 1533 by Diego Ribera de Toledo, Bishop of Segovia, with Francisco Zamora de Orello, Titular Bishop of "Brefny", and Francisco Solís, Bishop of Drivasto, as Co-Consecrators. After another year in Spain working for favourable concessions for the Indians, he reached Mexico in October 1534, accompanied by a number of mechanics and six female teachers for the Indian girls. He no longer held the title of Protector of the Indians, as it was thought that the new auditors would refrain from the abuses of prior regimes. On November 14, 1535, with the arrival of the first viceroy, Antonio de Mendoza, the rule of the new auditors ended.
