The navigational freedoms are unavoidably curtailed to some degree in the exclusive economic zone (EEZ) as compared with the traditional high seas freedoms. One of the main reasons for this compromise was to accommodate coastal States’ sovereign rights and jurisdiction in the newly established maritime zone. Nevertheless, the limitation of the navigational freedoms by the coastal State can only be justified if they are made in accordance with the formula of the attribution of rights and freedoms in the EEZ and must be exercised in good faith and by giving due regard to the exercise of these freedoms and rights. It is noteworthy that coastal States have been able to utilise mechanisms developed by competent international organisations to adopt and implement some of these limitations through the rules of reference, particularly regarding the protection and preservation of the marine environment from international shipping. This chapter first identifies the scope of the preserved freedoms of navigation and overflight in the EEZ, then examines how they may have been affected by the exercise of a coastal State’s rights and jurisdiction, before discusses the remedies to address these impacts.

The rights and duties of flag States go hand in hand under the UNCLOS legal framework. A State bears the right to grant a ship its nationality and is entitled to exercise exclusive jurisdiction over the ship. At the same time, a flag State has the obligation to effectively exercise its jurisdiction and control over the ship sailing under its flag. While the provisions relating to flag States’ rights and obligations are found in Part VII UNCLOS entitled ‘High seas’, their application apply to wherever the ship may find itself. Given the omnipresence of ships at seas, clarity and certainty regarding flag States’ rights and obligations is crucial for the effective implementation of UNCLOS, as well as for ensuring delicate balance between the rights and obligations of coastal States and of flag States upon which UNCLOS hinges. This chapter examines the decisions of UNCLOS tribunals relating to flag States’ rights and obligations, in order to examine whether and to what extent UNCLOS tribunals have contributed to the clarification and development of the relevant rules pertaining to flag States.
