It seemed sure that, starting January 10, Venezuela would experience high uncertainty. Nicolás Maduro swore in the presidency for the 2019-2015 government period in front of the Supreme Court of Justice (TSJ), when the constitution of that country dictates that it is before Parliament that the president must present the inauguration. Both the international community and the National Assembly (AN), declared in contempt by the Supreme Court, mark Maduro as an usurper. The illegitimacy of the president is discussed globally and Juan Guaidó is recognized as interim president of the Republic.
