Soft law in the constitutional debate

Abstract

This article deals with the analysis of soft law, in terms of its conceptualization, its characteristics, and its situation about public international law, to determine its role as a source of international law. It incorporates references to comparative constitutional regulation, such as the cases of Mexico, Argentina, and Spain, as well as to the role of custom as a source of public international law. It concludes the work with well-founded recommendations regarding the inconvenience of including soft law in a constitutional text.
