The practical consequence of the Constitutional Court’s balancing approach to maintain both security and liberty has been a shifting jurisprudence, a fact that is bound to buoy and bother American conservatives and progressives in equal measure. There is something in the Court’s cases for both camps. Before 9/11, the Court deferred to the legislature’s attempts at promoting security. This inclination, however, changed dramatically in the post-9/11 period. In a string of cases the Court has consistently invalidated national security legislation for failing to adequately take account of constitutionally protected liberty interests.
