Deviation

The carrier in sea transportation is obligated to proceed with the voyage on the contractual route. The violation may exempt the insurer from supporting the loss and damage to cargo after deviation from the route. Regarding the importance of marine insurance contract validity in international commerce, this question arises whether the ship deviation invalidates the insurance contract and exonerates the insurer to compensate. In the English marine insurance act 1906, the insurer is exempted from compensating for damages and the courts consider the claim regarding the circumstances governing the case. The lack of a marine insurance act in Iranian legislation requires us to consider the matter of the general rules in the insurance act 1937 that analyze performance guarantees such as invalidity and right of termination on the contract. If the additional insurance premium is not agreed upon in the contract, the right to terminate the contractual relationship is an approach that protects the insurer in different cases. Nowadays, because the insurance companies do not fully compensate for the damage, part of that is compensated by the P&I clubs. In fact, there is a kind of supplementary compensation covered after deviation. The mentioned question is analyzed with the descriptive-analytical method and library sources in this article. 

Deviation of the ship from the contractual or custom route during sea transportation affects not only the contract parties, but also the rights of third parties, and one of the most important parties is the bill of lading holder. The necessity of supporting the bill of lading holder rights and the legal solutions in Iranian and Britain legal systems are analyzed in this article. In Britain's legal system, the social welfare theory is one of the mechanisms designed for the various models to support the person's rights. Under the mentioned principle the bill of lading holder has the right to invoke the contents of the maritime transport contract, and under Iran's legal system, due to Article 12 in The Civil Liability Act 1960 along with the provisions contained in The Revised Sea Act 2011, joint and several liability for the third parties has been recognized. In this article, the effect of deviation on the bill of lading holder rights is analyzed with descriptive-analytical methods and library sources.
