The constitution provides that in case of the death, resignation or disability of the president the Congress shall by law designate the person who is to act as president until the disability ceases or a new president is elected, and that if Congress is not sitting the Cabinet officers are immediately to call a session. This is an innovation, as from 1853 to 1907 the Dominican constitutions provided for a vice-president. The vice-president was generally a decorative feature. He was required to possess the same qualifications as the president and was chosen with the same formalities, but no duties were assigned to him, not even that of presiding in Congress, so that his only attribute was the glory of being a president in escrow. The newly elected vice-president therefore often quietly retired to his farm, emerging occasionally to act in the president's stead when the latter left the capital on a trip through the country. Frequently the vice-president was made delegate of the government in some part of the country and at times he was invested with a portfolio as one of the cabinet secretaries. During the administration of a strong president, as in the time of Heureaux, the vice-president was generally one of his satellites, whereas, when the president's power was not so firmly established, as in the administrations of Jimenez and Morales, one of his rivals would be mollified by the vice-presidency. In such cases friction frequently developed, and in the two cases specified the vice-presidents and presidential rivals, Vasquez and Caceres, overthrew the president and established themselves in power. Evidently in order to avoid such disturbances and temptations the constitution of 1908 abolished the office of vice-president. The lack of a definite successor to the president, however, enabled Victoria to seize the presidency after the death of Caceres in 1911 and has given rise to uncertainty and trouble in the cases of presidential succession since that time.
