The regime of navigation on international waterways: Part III: Substantive rights and duties

Abstract

The term “navigation” in the purely technical sense means no more than the movement of vessels; in this sense the term is used in regulations bearing on the technical conditions for the movement of ships. “Navigation”, the freedom of which is established in international treaties, has a quite different meaning. Freedom of communications (including freedom of navigation on rivers) and freedom of commerce had already been conceived as correlative and complementary notions in natural law. Both the earliest and most recent treaties on inland navigation give conclusive evidence that dissociation of these two notions was never contemplated. It is true that freedom of navigation and freedom of commerce are, in principle, concerned with different matters. Navigation understood as the mere movement of vessels, may be exercised for scientific, philanthropic or recreational purposes. However, such movement of vessels for non-commercial purposes was never of such importance as to justify international regulation. Every international agreement in this field has envisaged granting freedom of navigation as an economic activity. Never, in international treaties, has navigation been treated exclusively as movement of vessels in the technical sense, viz. as an activity with an end in itself. On the contrary, for the purpose of international regulation, navigation has constantly been regarded as an economic activity, viz. as the operation of transport services for passengers and, in particular, goods. In other words, the international regulations have always regarded navigation as the exercise of the shipping trade.
