Too Legit to Quit? Analyzing the Effect of No-Confidence Motions on Cabinet Members’ Instability in Presidential Systems: The Cases of Colombia and Peru

ABSTRACT How does the execution of horizontal accountability mechanisms affect cabinet members’ instability? This article analyzes distinct features of no-confidence motions (NCMs) in presidential systems, using a mixed-method research design that identifies elements of legislative control mechanisms in Peruvian and Colombian polities. Although the congress in presidential systems rarely approves NCMs, high salience policy shocks trigger their proposal, resulting in the dismissal or resignation of the cabinet member in question. Those results are subtle opportunities for opposition legislators to indicate the incompetence of the incumbent government in particular policy areas. This study contributes to understanding how contextual factors affect the effectiveness of the check and balance principle in presidential systems.
