Articles 3 and 4 of the Convention cast on each State Party the responsibility of identifying and delineating properties on its own territory which are part of the cultural heritage or natural heritage. To discharge this responsibility, an evaluation must be made of the qualities of properties in order to ascertain whether there are properties of "outstanding universal value" in the territory of the State Party. In one sense, the status of a particular property as one of outstanding universal value forming part of the cultural heritage or natural heritage is an objective fact, ascertainable by reference to its qualities; but, as evaluation involves matters of judgment and degree, an evaluation of the property made by competent authorities under the Convention is the best evidence of its status available to the international community. The competent authorities to make an evaluation for the purposes of the Convention are, in the first place, the State Party on whose territory a property is situated and, if the State Party submits a property in an inventory under Art. 11, par. 1, the Committee under Art. 11, par. 2. Not all properties which are part of the cultural heritage or natural heritage may be included by the Committee in the World Heritage List but, under Art. 11, par. 2, all property included in the World Heritage List must be part of the cultural heritage or natural heritage and must also meet the special criteria for listing established by the Committee. Unless the Committee is satisfied on both aspects, the property is not included in the World Heritage List. By including a property in the World Heritage List, the Committee declares its satisfaction that the property is part of the cultural heritage or natural heritage. As the procedures for evaluation adopted by the Committee are extensive, the Committee's decision to include a property in the World Heritage List assures the international community that the property has outstanding universal value as part of the cultural heritage or natural heritage. Article 12 of the Convention provides expressly what would otherwise be implied, namely, that the fact that a property has not been included in the World Heritage List does not determine that the property does not have "an outstanding universal value" for purposes other than those "resulting" from inclusion in the List. The phrase "purposes other than those resulting from inclusion" is not easily understood but it excludes the purposes which may be served by inclusion of a property in the World Heritage List. Listing entitles a State Party to call on other States Parties to give their help in the identification, protection, conservation and preservation of property under Art. 6, par. 2 and authorizes a grant by the Committee of international assistance for the protection, conservation, presentation or rehabilitation of the property under Art. 13: see Arts 20, 22 and 23. These articles are the only articles of the Convention which state the consequences of including a property in the World Heritage List or in the "List of World Heritage in Danger" (which in turn includes only properties that have been included in the World Heritage List: Art. 11, par. 4).
