Therefore, the concluding article2, quoted in the second paragraph of the commentary on the above point, in which «the primary means of interpretation covered by section 31, all of which must be taken into account in the process of interpretation,» is incorrect. Only the instruments of interpretation covered by Article 31, paragraph 3, must be taken into account. The provision of Article 31, paragraph 1, is not only taken into account, but also effective or applied. In this context, the four reports by the Special Rapporteur of the Commission on International Law, Mr Georg Nolte, on subsequent agreements and the practice followed with regard to treaty interpretation (`reports`), will almost inevitably be recognisable in a range of approaches not only of legal methodology, but also of international policy.  The leitmotif of the reports is the distinction between, on the one hand, a subsequent agreement and a subsequent practice within the meaning of Article 31, paragraph 3, of the Vienna Convention on treaty law (VCLT), and, on the other hand, another subsequent practice, as covered by Article 32 of the VCLT.  The degree of obligation to use such substances is different: while Article 31, paragraph 3, of the VCLT, provides that a subsequent agreement «on the interpretation of the contract or the application of its provisions» as well as «the practice in the application of the contract that determines the agreement between the parties on its interpretation», the other subsequent practice must be considered as a means of further interpretation. determine the «recourse» (evidence) of the meaning resulting from the application of section 31 or the meaning whether the result of such an interpretation is either a) «clear or opaque» or b) «manifestly absurd or inappropriate». At this stage, the study leaves the impression that it combines two questions, one on the legally binding nature of judicial and quasi-judicial decisions and the other on their characterization of further practice. This alone does not explain, but it is part of the application of the jurisprudence of the European Court of Human Rights as a source for detecting subsequent practices in cases where the Court of Justice conducts comparative studies on the individual guarantees of the European Convention.  First, it is true that section 31 is called the «general rule.» However, this does not support the conclusion that section 31, point 1, of the interpretation procedure is «not a priority». There are things worth talking about in section 31. First, Article 31, paragraph 3, as Article 31, paragraph 1, is formulated in the mandatory «must,» but the order serves only to take into account subsequent agreements and subsequent practices.
