Review of international treaties

The competence of the Constitutional Court to subsequently review the constitutionality of international treaties or individual provisions of international treaties that have already been legally concluded by the Principality of Liechtenstein is disputed in legal theory, since in international law, among other things, the principle of Pacta sunt servanda applies.
This review authority of the Constitutional Court is considered to be very problematic, particularly in view of the Principality's integration into the European Economic Area. According to Article 23 paragraph 1 of the Constitutional Court Act, if the Constitutional Court finds that an international treaty or individual provisions thereof are incompatible with the constitution, it can revoke the domestic binding nature of the treaty. This could lead to a domestic court having subsequent review authority with regard to EEA law and undermine the primacy of EEA law, but the EEA process for incorporating EU law has generally proven to be robust.
