Tribunales constitucionales y secesión: ¿reivindicación (potencialmente) legítima o violación de un principio básico?

This article analyzes the issue of secession in comparative constitutional law, through the prism of constitutional jurisprudence. Its main axis is the openness to secession as a political aspiration, and therefore the two fundamental cases are Spain (most open) and Germany (most restrictive). Framed also in the context of Italian and Canadian case law, these cases are used to draw conclusions about the constitutional and political reasons for such different judicial positions.
