The Classification of Obligations and the Multilateral Dimension of the Relations of International sponsibility Lions-Alexander Sicilianos

The final version of the Articles on State Responsibility, adopted by the ILC in 2001, contains considerable advances over the previous draft of 1996. The ILC reconsidered the group of provisions dealing with the multilateral aspect of responsibility relations, and proceeded to 'decriminalize' international responsibility; to classify international obligations by taking into account the intrinsic nature and beneficiaries of the obligations breached; to differentiate the positions of individually injured states and not directly affected states; and to spell out the legal consequences of 'seriou's breaches of obligations under peremptory norms and of ergaomnes obligations. The present paper offers a critical analysis of the relevant provisions of the text on state responsibility by focusing on their interplay. Emphasis is also given to the question of countermeasures by not directly affected states.
