Waibel: The Principle of Privity

Michael Waibel (Univ. of Cambridge - Law) has posted The Principle of Privity. Here's the abstract:

In Certain German Interests in Polish Upper Silesia, the Permanent Court of International Justice (PCIJ) said: 'A treaty only creates law as between the States which are parties to it; in case of doubt, no rights can be deduced from it in favour of third States'. This is the classic statement of the privity, pacta tertiis or parties-only principle in international law. Accordingly, treaties create (enforceable) obligations and rights only for the States parties to them. The Vienna Convention on the Law of Treaties (VCLT) codified the privity principle in its Articles 34, 35, 36 and 37.

As this chapter shows, the PCIJ's axiomatic statement in Certain German Interests almost eighty years ago no longer fully reflects the effect of treaties on third parties in contemporary international law. Since then, the principle of privity of treaty has lost some its sharp edges. The rise of erga omnes obligations and objective, status-creating treaties, the conferral of rights on non-State actors and their ability to directly enforce such rights as well as the turn towards informal international law beyond the law of treaties have tempered the traditional privity rule. However, it would be premature to sound the death knell of privity of treaty. Privity remains an important structural characteristic on the inter-State plane.
