The coup, at least in the commentary on The Draft Closure 2, is in paragraph 6 of the commentary. In this case, the Commission praises the importance of Article 31, paragraph 1, and then undermines its priority: as if it were projecting the distinction between agreed and subsequent practices in the context of the restrictive/effective dichotomy, the reports indicate that the following practice may have both support and restriction effects, which it may limit or expand the range of possible outcomes.  This seems to imply that the ILC does not purport to participate in a policy debate on restrictive or far-reaching interpretations. The emphasis is on the intention to get as close as possible to the “authentic” importance of a treaty.  But the “authentic” can also be treated in different ways, i.e. from the point of view of state sovereignty, which would trigger connotations to the rule of thebio-mitius, or by following a term which aims to give a treaty the broadest scope, incompatible with other methods of interpretation of the contract for which the rule of useful effect is used.  The claim to be seeking authentic meaning is therefore not necessarily the same as remaining neutral between these two positions. With respect to Class II, in addition to the reference already mentioned in the Nuclear Weapons Notice to the Organization`s “own practice,” the cases referred to by the ICJ contain other opinions, in which the ICJ has not made a statement on the exact interpretive value of institutional practice.  In the reports, the term “at least” is considered “other after-practice” in accordance with section 32 of the VCLT.  In trying to indicate as precisely as possible how far such a practice could go, the reports attempt to assess the material found and to balance the different possible approaches that under the basis of such an exercise. Overall, however, the end result seems to follow a relatively narrow understanding: the text of Article 31 of the VCLT (“parts” “in the application of the treaty”) is interpreted in a restrictive manner, the subsequent practice, as an interpretive element, refers to one of the three elements of the (first) uniform rule of Article 31, paragraph 1, of the VCLT, and qualifies the “own practice” of international institutions as a means of interpretation.
