The Systemic Equivalence Test and the Presumption of Equivalent Protection in European Human Rights Law—A Critical Appraisal

Abstract The systemic equivalence test constitutes an important tool in European Human Rights Law: It is used in order to structure the different systems of protection that apply in a common space and to common addressees. More precisely, where there is “systemic” equivalence between different legal orders protecting fundamental rights, a presumption of compatibility of concrete legal acts is applied. While this technique is very useful in the context of a multi-layered legal landscape, this systemic approach currently seems to be very poorly conceptualized by the various judicial instances calling upon it. This may entail risks for the protection of fundamental rights in Europe, as certain acts may benefit from a presumption of conformity even though they are adopted by legal systems that do not have the qualities required to benefit from it. This article critically assesses this technique, and provides avenues for improvement of its use.
