El desarrollo de la garantía de la motivación en la jurisprudencia constitucional

Abstract

Abstract:This study analyzes the development of the guarantee regarding the requirement to provide reasons for decisions (*motivación*) within Ecuadorian constitutional jurisprudence, examining its constitutional, doctrinal, and jurisprudential foundations within the framework of due process. It examines the evolution of criteria established by the Constitutional Court of Ecuador concerning this guarantee and outlines the current applicable standards. To achieve this, a qualitative legal approach was employed, supported by a documentary review of the Constitution, specialized legal doctrine, and rulings issued by the Constitutional Court. The analysis reveals that the interpretation of this guarantee has evolved from a model based on criteria of reasonableness, logic, and clarity toward a standard based on the sufficiency of the reasoning provided, as established in Judgment No. 1158-17-EP/21. The study concludes that the requirement to provide reasons is an indispensable guarantee for protecting due process, effective judicial protection, and legal certainty; it mandates that decisions by public authorities be duly substantiated, thereby strengthening the legitimacy of state action and providing a safeguard against potential arbitrary conduct.
