He was a lawyer and a government representative. He studied in the School of San Francisco Javier de Querétaro, and then moved to Guadalajara where he continued with his education in the School of San Juan Bautista. In 1792 he obtained his law degree and began his career by litigating at the Court of Guadalajara. In 1795 he moved to Mexico City where he enrolled in the Royal College of Law. A few years he received a doctorate of Canon Law at the University of Guadalajara.

He was elected Alternate Government Representative of Querétaro in 1810 and 1813 after the resignation of Fray Lucas Centeno. Besides being a member of several commissions, he was the vice-president of the Cortes. He was an active participant in the parliamentary debate where demonstrated to be very knowledgeable about Hispanic historical law. He was a great defender of the argument shared by other Latin American government representatives that it was fair to meet the expectations of the provinces that, in many cases, were fighting internal insurrectionary movements and demonstrating loyalty to the Spanish Crown. In this sense, he was in favor of seeing Latin American representation increased, giving, among other things, citizenship to the castes. His defense of the Indians was more ambiguous since he was in favor of maintaining some privileges that were recognized by the previous legislation. He was in favor of the freedom of trade and also in favor of the contribution by the Latin American church to the economy of war. He was against the Cortes of 1813 because of the difficulties that this entailed in the arrival of the deputies from outside the Iberian Peninsula. He was part of the commission that drafted the Constitution and was very interested in the treatment of the judicial aspects in the new constitutional system.

In 1814 he returned to America and joined the Royal Court of Guadalajara where he held the position of prosecutor. After the independence, he became a judge at the Regional Court of Mexico, a position he held simultaneously with the one of deputy director of the Patriot Board of Guadalajara and Government Representative in the Mexican Congress. He was in favor of Iturbide's coronation.
