The concept of legal pluralism tries to come to terms with tensions between different kinds of law. It does not only refer to the constitutive tension between citizenship rights as particularistic and exclusionary and human rights as universalistic and inclusionary. Not uncommonly supranational law contradicts national law. In this respect, in recent years the most obvious examples in Europe are the impact of human rights and European courts on national legal institutions.
