Abstract
This article considers the nature of the right to public
participation in environmental decision-making in
international law. In doing so it briefly examines the
rationales for public participation, its features and the
various manifestations of the right in different international
law treaties and instruments, as well as jurisprudence on
the international scale which deals with it, finally addressing
the question of whether the twin requirements for a
customary international law, state practice and opinio juris,
are met.
