The opposition leader, Juan Guaido’s power is shrinking in Venezuela and he is often ignored. He has no transitional government, even Elliot Abrams admits he is not in power, and Guaido has been barred from running for office for financial improprieties after being investigated for illegally taking money from a foreign government. Guaido’s immunity from prosecution has been removed and he has been forbidden from leaving the country. He has announced major protests multiple times to support his takeover of the Venezuelan government on behalf of the US government, but the protests are often canceled or have small turnouts.
Juan Guaidó’s self-appointment as interim president violated the Constitution of Venezuela. The language of the Venezuelan Constitution is clear regarding when the president of the National Assembly can become president and none of the conditions in the Constitution have been met.
The opposition relies on Article 233 of the Constitution, which allows the National Assembly president to serve as interim president only if the president-elect has not yet been inaugurated. Guaidó’s self-appointment occurred after President Maduro had been inaugurated.
Article 233 allows the president of the National Assembly to become president only if the president-elect:
“become[s] permanently unavailable to serve by reason of any of the following events: death; resignation; removal from office by decision of the Supreme Tribunal of Justice [equivalent of impeachment]; permanent physical or mental disability certified by a medical board designated by the Supreme Tribunal of Justice with the approval of the National Assembly; abandonment of his position, duly declared by the National Assembly; and recall by popular vote.”
None of these conditions were met. [Source]
