Introduction 

• The Right to Innocent Passage is a fundamental principle enshrined in international law, particularly within the United Nations Convention on the Law of the Sea (UNCLOS).  
• The Right to Innocent Passage allows foreign vessels to navigate through the territorial waters of a coastal state, provided that such passage is not prejudicial to the peace, good order, or security of the state.  
• This principle is crucial for maintaining the balance between the rights of coastal states and the freedoms of navigation enjoyed by other states.  
• The concept is primarily articulated in Part II, Section 3 of UNCLOS, which outlines the conditions and limitations of innocent passage. 

Definition of Innocent Passage 

• According to Article 17 of UNCLOS, "ships of all states, whether coastal or land-locked, enjoy the right of innocent passage through the territorial sea."  
• Innocent passage is defined as navigation that is not harmful to the security of the coastal state under Article 18 of UNCLOS. 
• Article 19 of UNCLOS further elaborates on what constitutes innocent passage, stating that passage is considered innocent as long as it is not: 
  • Prejudicial to the peace: Activities that could disturb the tranquility of the coastal state. 
  • Threatening the good order: Actions that could disrupt the legal and social order of the coastal state. 
  • Harmful to the security: Any conduct that poses a threat to the state's safety, including military activities or espionage. 

Conditions for Innocent Passage 

• While the right to innocent passage is a recognized principle, it is subject to certain conditions.  
• Article 18 of UNCLOS stipulates that passage must be continuous and expeditious.  
• This means that vessels should not linger unnecessarily in the territorial sea and must not engage in activities that could be deemed as stopping or anchoring without justification. 
• Additionally, coastal states have the authority to regulate innocent passage through their territorial waters.  
• Article 21 allows states to adopt laws and regulations concerning: 
  • The safety of navigation and the regulation of maritime traffic. 
  • The protection of navigational aids and facilities. 
  • The prevention of pollution. 
  • The preservation of the marine environment. 
  • Rights of Coastal States 
• As per Article 25 of UNCLOS: 
  • The coastal State may take the necessary steps in its territorial sea to prevent passage which is not innocent. 
  • In the case of ships proceeding to internal waters or a call at a port facility outside internal waters, the coastal State also has the right to take the necessary steps to prevent any breach of the conditions to which admission of those ships to internal waters or such a call is subject. 
  • The coastal State may, without discrimination in form or in fact among foreign ships, suspend temporarily in specified areas of its territorial sea the innocent passage of foreign ships if such suspension is essential for the protection of its security, including weapons exercises. Such suspension shall take effect only after having been duly published. 

Responsibilities of Coastal States 

• As per Article 24 of UNCLOS: 
  • Coastal states are required to ensure that their laws and regulations regarding innocent passage are consistent with international law.  
  • They cannot impose restrictions that would effectively deny the right of innocent passage.  
  • Furthermore, any measures taken must be necessary for the protection of their interests and should not be discriminatory against foreign vessels.
• In addition to it, as per Article 26 of UNCLOS charges which may be levied upon foreign ships as:  
  • No charge may be levied upon foreign ships by reason only of their passage through the territorial sea. 
  • Charges may be levied upon a foreign ship passing through the territorial sea as payment only for specific services rendered to the ship.  
  • These charges shall be levied without discrimination. 

Implications for Maritime Navigation 

• The Right to Innocent Passage plays a crucial role in facilitating international trade and maritime navigation.  
• It ensures that vessels can traverse territorial waters without undue hindrance, promoting economic cooperation and connectivity among nations.  
• However, tensions can arise when coastal states perceive certain activities as threatening their security, leading to potential conflicts over the interpretation of what constitutes innocent passage. 

Conclusion 

The Right to Innocent Passage under the UN Convention is a vital aspect of international maritime law, balancing the rights of coastal states with the freedoms of navigation for all states. Understanding the legal framework and implications of this principle is essential for ensuring peaceful maritime relations and fostering cooperation in the global maritime domain. As international waters continue to be a focal point for trade and geopolitical interests, the principles governing innocent passage will remain significant in maintaining maritime security and stability.
