3.4 Teachings of most qualified publicists

Article 38(1)(d) of the Statute of the ICJ states that the ICJ will also apply 'the judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law'. This provision and the preceding Article (1)(c) are of less importance than the first two sources of law in Article 38. However, eminent scholars and distinguished authorities in international law continue to have some influence conceptually. Arbitration tribunals and other bodies engaged in resolving disputes may cite authors in the deliberations. Distinguished writings thereby contribute as a source of international law.

Note down any examples that you are know about of the implementation of international environmental law through its various sources in the legal system of the state/country in which you reside.
