Are strikes at ports force majeure events? and what are the consequences? This is an issue in shipping because a strike in a port backs up traffic– ships cannot load or unload, and cargoes are massively delayed. The result is that much money is lost. A lot more than if ground transport is involved, because you only have the choice of ocean or air modes, vastly different in cost and capability.
Here we see that force majeure is not really defined in law, and that economic loss is not a reason for force majeure– it is always a possibility in commercial transactions, and you are supposed to consider that possibility when signing a contract.
