To what extent can a State forego its contractual commitments, in particular those arising from a stabilization clause for human rights and environmental protection? (“under a stabilization clause, the host State commits itself either not to enact changes of the domestic law in the future, or at least, not to apply such changes to the investor”, Ohler, Concessions, Max Planck Encyclopedia, 2009.) Our assumption is that stabilization clauses and states’ rights to regulate should be integrated and not be taken as opposite obligations, considered as incompatible. In other words, if framed correctly, stabilization clauses can balance the two conflicting needs at stake: the sanctity of contract and a state’s right to regulate to protect its public interest (Leben, L’évolution de la Notion de Contrat d’État, Revue de l’arbitrage, 2003; Carbone, Luzzatto, Il Contratto internazionale, 1996; Giardina, State Contracts, national versus international law, The Italian Yearbook of international law, 1980; Fatours, International Law and International Contract, 1980; Mann, State Contracts in International Arbitration, 1967).
This post examines whether the (fairly) new European exclusive competence on foreign direct investment changes the way stabilization clauses should be framed in EU State contracts to avoid potential conflicts. There are two different kinds of possible conflicts that could arise: first involving either provisions among themselves, or second, the two different legal regimes at stake (the international and the European).
