Party member and opposition Senator Jeanine Áñez became interim president of Bolivia in November 2019, following protests caused by alleged electoral fraud which led to the resignation of the government of Evo Morales. This move was contested by senators for the Movement for Socialism (MAS), Morales' party, who were majority in the assembly and were not in attendance, and thus stated that the vote for interim president took place without a quorum. However, the decision was upheld by the Plurinational Constitutional Court, which stated that it followed the succession mechanism stated in the Constitution of Bolivia.
