372. Pursuant to article 31 of the Vienna Convention, the Convention is to
be interpreted in good faith in accordance with the ordinary meaning of its
terms in their context and in the light of its object and purpose. As stated in
the Advisory Opinion of the Seabed Disputes Chamber, article 31 of the
Vienna Convention is to be considered “as reflecting customary international
law” (Responsibilities and obligations of States sponsoring persons and
entities with respect to activities in the Area (Request for Advisory Opinion
submitted to the Seabed Disputes Chamber), 1 February 2011, para. 57).
373. The Convention sets up an institutional framework with a number of
bodies to implement its provisions, including the Commission, the
International Seabed Authority and this Tribunal. Activities of these bodies are
complementary to each other so as to ensure coherent and efficient
implementation of the Convention. The same is true of other bodies referred
to in the Convention.
