What is a requirement for a coastal State to verify a claim of force majeure?

A coastal State must often take specific steps to verify claims of force majeure, which may include the necessity of boarding the vessel. By boarding the vessel, officials can directly assess the situation, gather relevant evidence, and determine the validity of the claims made by the vessel's crew. This allows for a thorough evaluation of the circumstances that led to the claim, enabling the coastal State to make informed decisions regarding its responsibilities and enforcement actions based on the observed condition of the vessel and crew.

Engaging directly with the vessel through boarding provides the means to verify information firsthand, rather than relying solely on documentation or claims made by the crew. This process plays a crucial role in the enforcement of maritime law, ensuring that claims of force majeure are valid and justifiable within the context of international maritime regulations.
