Article 34

General rule regarding third States
  • Alexander Proelss


Art 34 contains the Convention’s general rule regarding the effects of treaties in respect of third States. For States who have not expressed their consent to be bound by its terms, a treaty constitutes res inter alios acta. The underlying notion, embodied in the maxim pacta tertiis nec nocent nec prosunt (agreements neither harm nor benefit third parties), may appropriately be described as the negative facet of the principle of pacta sunt servanda and is founded on the principles of sovereignty and independence of States. While the pacta tertiis rule is not valid in an absolute manner, this does not alter the fact that a treaty generally has only a relative effect, ie is valid inter partes.
