A recent English court decision examined two critical aspects of force majeure clauses in commercial contracts: what constitutes an "unforeseeable" event and whether notice requirements operate as conditions precedent. The case arose from a grain shipment dispute involving a vessel stranded in the Black Sea during the Ukraine invasion, where the seller invoked force majeure after Russian inspectors halted vessel inspections.

A dispute over a ship stranded in the Black Sea raised two interesting points on force majeure: the meaning of “unforeseeable” and whether a notice requirement was a condition precedent.

A grain deal gone wrong

Inerco agreed to sell Ukrainian corn to ADM Israel, due to be shipped between April and May 2023. A force majeure clause dealing with “prevention of shipment” covered “unforeseeable … impediments” and required notice “within 7 consecutive days of the occurrence”. A separate extension clause required notice “not later than the next business day” after the “originally stipulated period”. 

Due to the invasion of Ukraine, ships entering the Black Sea to load grain were inspected. In May, the Russian inspectors stopped inspecting inbound vessels. Inerco therefore invoked the force majeure clause. When ADM Israel rejected this, Inerco treated that as a renunciatory breach and terminated the contract.
