The Constituent Congress (Congreso Constituyente) terminated the functions of executive power (29 Mar 1823) which had existed since 19 May 1822 and resolved to appoint an executive body but postponed the election to 31 Mar 1823 when Bravo, Guadalupe Victoria, and Negrete were elected to form a Supremo Poder Ejecutivo. Negrete was sworn in immediately, as the other members were absent. The alternates (Michelena and Domínguez) were appointed and sworn in on 1 Apr 1823 to serve until Bravo and Victoria could assume office. Domínguez was discharged shortly before Bravo took the oath of office on 28 May 1823, while Michelena continued to serve. On 2 Jul 1823, the Congress designated Michelena and Domínguez as permanent alternates (suplentes perpetuos) to serve during the absences of the members of Supremo Poder Ejecutivo. Guerrero was elected as the third alternate during the night session of 2/3 Jul 1823 and took the oath of office on 3 Jul 1823.
A decree appointing the Supremo Poder Ejecutivo prescribed a monthly rotation of the presidency among its members, following the order of their appointment, but did not specify the exact date on which each was to assume the presidency.
