In the last two decades, the margin of appreciation has become a cornerstone of the Convention system, but it remains a contested and undertheorized concept. Stijn Smet argues that the European Court has never fully explained exactly what the margin of appreciation is or does. J.G. Merrills notes that the margin of appreciation is fraught with difficulty, and Steven Greer concludes that the most striking characteristic of its application remains its casuistic, uneven, and largely unpredictable nature. This ambiguity primarily concerns the question of when and why the Court grants states a ‘certain’, a ‘narrow’, or a ‘wide’ margin of appreciation. On the one hand, this elusive character enables the margin of appreciation to function as a ‘lubricant’ in the Convention system. On the other hand, this elusive character might undermine central legal principles such as legal certainty and the rule of law.

This colloquium will analyze the margin of appreciation as the bridge between the universal presence of human rights and their concrete implementation. It is organized by the Department of Foundations and Methods of Law in collaboration with the Maastricht Centre for Human Rights.

This colloquium will be conducted in a hybrid format offering attendees the option to join virtually via Zoom or in-person in Maastricht.
