Spanish magistrate and law specialist.

Son of Francisco Ignacio Lardizabal Elorza and Isabel María de Uribe-Castejón. Brother of Manuel de Lardizábal Uribe, among others.

He was the adviser of Charles III, a member of the magistrates court in Granada and public prosecutor of the Supreme Court.

He remodelled the criminal legislation, being influenced by Beccaria, and wrote the Discurso sobre las penas, contracted to the criminal laws of Spain, to facilitate the reform in 1782. He was the brother of Miguel de Lardizábal y Uribe, Universal Minister of the Indies during Ferdinand's VII reign. Both of them were teachers in the influential Royal Economic Society of Friends of the Country of Vergara (Gipuzkoa). He was married to María de la Cruz Montoya y Molina, and they had four daughters.

He studied Fine Arts and Philosophy, and he had a bachelor's degree in Theology by the University of Mexico. After that, he moved to Spain, he reached a total formation in Law by the University of Valladolid, that allowed him to be a lawyer of the Chancery and the Royal Councils. In 1770, he was appointed supernumerary academic in Madrid by the Royal Spanish Academy; he tried, without luck, to sit for an official exam for a position in the Law chair of the Royal Studies of San Isidro. In 1775, he became a full member academic in the Royal Academy. At the same time, he started his written work in relation to criminal law. He worked in the Sala de Hijosdalgo of the Royal Chancery of Granada, and later on he was appointed attorney of the Sala de Alcades de Casa y Corte and attorney in the Council of Castilla; being the Council's Minister, Godoy's promotion was fatal for his professional career. He was banished in 1794 and had to wait until the 19th century to regain public projection. He was member of the Reunited Council in Madrid (1808) that declared the nullity of the renunciation of the Crown and Bayona's Constitution, as well as all the actions of the intruder government. After Ferdinand's VII return, he joined the Council and House of Castilla. He cooperated in the bilingual edition of Fuero Juzgo in 1815, and he was appointed by Ferdinand VII 7th Honorary State's Adviser to the Provisional Advisory Junta. He was against the libreal uprising of 1820.

His best legacy was his criminal lawyer work, and his text is the first specific treatise on penology in law's history. His method to enumerate the general characteristics of punishment was later adopted by treatises and prevails to this day.
