Article 16 of the Acta Constitutiva was put to a vote on 2 January 1824 at an extraordinary session. It was defeated by a vote of 42 to 25. As a result, the congress did not address Article 17, which dealt with the vice-president. The proposal to establish a president and a vice-president was one of the few instances in which the second constitution of the United States served as a model. The majority did not agree with the proposal because it feared the possibility of one individual dominating Congress through military or popular forces, as Iturbide had done. The commission on the constitution revised the articles on the executive a number of times, but could not obtain support for its proposals.
