This Article analyzes the role played by international actors, indigenous peoples, and independent lawyers as guardians of democracy in a context where democratic backsliding, abusive judicial review, and institutional takeover has taken place. Using the Guatemalan 2023 electoral process as a case study, this Article sheds new light on authoritarian constitutional practices, evidenced through the judgments of the Guatemalan Constitutional Court and activities of its Criminal Prosecutor’s Office. This Article also considers how foreign governments, international organizations, indigenous peoples, and independent lawyers came to play a guardianship role in the face of the decline of core institutions of constitutional democracy. Techniques such as transnational sanctions, judicial challenges, diplomatic “shaming,” and protest movements were successful in upholding constitutional democracy by discouraging attempts by the courts and government officials to derail the transition of power and annul the electoral results. This Article analyzes how and why these techniques had an impact in the Guatemalan context and extracts lessons and insights, both positive and negative, for dealing with abusive constitutional practices in theory and in practice.
