Abstract The paper addresses the fundamental aspects of transitional justice in Colombia, within the legal framework developed to obtain peace and considering the broad case law of the Colombian Constitutional Court on the matter. To this end, after laying down some foundations concerning the scope of the constitutional principle of “peace” in the Colombian legal order and the concepts of justice, truth, reparation and guarantee of non-repetition, the study focuses on the legislative and judicial developments that have characterized the process, starting from its very beginning up until the report of the Commission for the Clarification of the Truth in 2022.
