El uso del Derecho extranjero y del Derecho internacional por parte del Tribunal Constitucional chileno durante el periodo 2006-2007

on a double perspective on the use of comparative law by constitutional judges in order to use extra-systemic or foreign elements in their argumentation, and on the constitutional doctrine that contemplates open constitutional systems and not self-centered ones, we will analyze whether the chilean constitutional court uses the constitutional law and the constitutional jurisprudence of other latin-american and european countries, as well as the international conventional law on human rights and the resolutions of their enforcement bodies. likewise, we will analyze why during 2006-2007 the constitutional court used the foreign and international law.
