The Specially-Affecting States Doctrine

  • Shelly Aviv Yeini (a1)
Extract

The orthodox view of the Specially-Affected States Doctrine (SASD), grounded in the International Court of Justice's (ICJ) 1969 judgment in the North Sea Continental Shelf cases, is that practice leading to the emergence of a customary rule must include that of states “whose interests were specially affected.” The framing of this passage of the North Sea Continental Shelf judgment seems to imply both a positive and a negative importance for the practice of specially-affected states. Such practice is a requirement for the emergence of a new rule of customary international law. Acceptance by specially-affected states is, in other words, necessary but not sufficient for a rule of custom to emerge. Whether practice of specially-affected states can be sufficient to form a general custom is not resolved by this formulation, although it seems reasonable to infer that the ICJ had in mind that the combined involvement of specially-affected and other states was needed for the formation of such a rule of customary international law concerning basic principles of continental shelf delimitation. Conversely, the absence of rule-supporting practice by specially-affected states would have a negating effect on the emergence of a rule of customary international law, despite rule-affirming practice of states not specially affected. On this view, practice of only such states could not crystalize into a custom. One commentator has suggested that the negative construction does not mean that a single specially-affected state necessarily holds veto power over the formation of a new rule of customary international law, but asserted that “[i]f several ‘states whose interests are specially affected’ object to the formation of a custom, no custom can emerge.” Unsurprisingly, given this level of abstraction, such formulations do not themselves provide specificity as to how many (or which) specially-affected states would be sufficient to prevent the formation of a custom in a particular situation.

36 This is not intended to suggest that omissions may not constitute practice. To the extent states that do not possess nuclear weapons do so because of a belief that such weapons are illegal, such opinio juris would be relevant in establishing custom. As has long been recognized, the reasons beyond the omissions of states matter for purposes of developing custom.
