 The Bolivian Constitution does not make specific provisions for the process of a Senator assuming the presidency; article 169 says that "In case of impediment or definitive absence of the president of the State, he will be replaced in office by the Vice President and, in his absence, by the President of the Senate, and in the absence of this by the President of the Chamber of Deputies.In the latter case, new elections will be called within a maximum period of ninety days.
