In 1978, the jurist Jorge Carpizo published El presidencialismo mexicano (Mexican Presidentialism) with Siglo XXI. Among the causes of the president’s dominance, he listed “las amplias facultades constitucionales y extraconstitucionales, como son la facultad de designar a su sucesor y a los gobernadores de las entidades federativas” (the broad constitutional and extraconstitutional powers, such as the power to designate his successor and the governors of the states).
In a text published by the Law Faculty of UNAM, Serrano Migallón writes that legal doctrine calls some of the president’s attributions “facultades metaconstitucionales” (metaconstitutional powers). A footnote there refers readers to Carpizo’s book.
