The paper assesses the widespread use of the test of proportionality in fundamental rights adjudication. While constitutional and human rights courts all over the world appear to be consistently engaged in deploying the test of proportionality in order to assess the permissibility of a given rights limitation, this approach is under severe criticism insofar as it is considered an attack to the very idea of fundamental rights. The paper will discuss this criticism of the use of proportionality, and will provide a defense of its use by courts in light of some basic features of the contemporary discourse of fundamental rights. / El artículo evalúa el uso generalizado de la prueba de proporcionalidad en la adjudicación de derechos fundamentales. Mientras que los tribunales constitucionales y de derechos humanos de todo el mundo parecen estar constantemente involucrados en el despliegue de la prueba de proporcionalidad para evaluar la permisibilidad de una determinada limitación de derechos, este enfoque está sometido a severas críticas en tanto que se considera un ataque a la idea misma de Derechos fundamentales. El artículo discutirá esta crítica al uso del principio de proporcionalidad y ofrecerá una defensa de su uso por los tribunales a la luz de algunas características básicas del discurso contemporáneo de los derechos fundamentales.
