On November 13 of 1868, President José Joaquín Pérez called him to the Interior ministry, entrusting to him a conciliation program with sights on the 1870 elections. He presided appropriately over the elections and, as they suffered numerous defects, he requested that they be corrected in the departments of Copiapó, Freirina, Putaendo, and Cauquenes. The conservatives requested a vote of censure that was rejected by 44 to 33. With this, he left the ministry.
