Which is an example of Non-Innocent Passage?

Non-Innocent Passage refers to situations where a vessel navigates through the territorial waters of a state but does not comply with the rules of innocent passage, which typically require that the passage be continuous, expeditious, and not prejudicial to the peace, good order, or security of the coastal state.

Fishing activities are considered a clear example of Non-Innocent Passage. This is because such activities typically involve the use of equipment that can disrupt marine ecosystems or fish stocks, and they may also violate the sovereignty of the coastal state, especially if done without permission or in designated protected areas. Engaging in fishing within the territorial waters of a state can lead to confrontations regarding resource management and rights, which inherently contradicts the principles of innocent passage.

The other options, while they can involve activities within territorial waters, do not necessarily indicate a breach of the innocent passage principles. Passing through without stopping is generally a hallmark of innocent passage. Commercial shipping is typically regulated and can be seen as compliant with international law when following designated routes, subject to local regulations. Tourist vessels, if operated under the guidelines of the coastal state and without disruptive activities, usually adhere to the concept of innocent passage as well.
