Jason Clause
A clause in a contract of carriage relating to liability of the shipowner under the US Harter Act in disputes concerning general average.
A clause appearing in contracts of affreightment where disputes may be subject to American Law. By the Harter Act 1983 the shipowner is not liable for faults in navigation or management provided he has exercised due diligence to make the vessel seaworthy. Nevertheless he could not claim any contribution from the cargo owner for general average expenditure or sacrifice which resulted from faulty navigation or mismanagement. Carriers, therefore, introduced a clause into contracts of affreightment whereby the cargo owners agreed to pay such contributions.
The case of the vessel "Jason" in 1912 tested the validity of the clause, and the present clause, the "New Jason Clause", provides that the expenditure or sacrifice must not result from lack of due diligence by the shipowner for the cargo owner to be liable for general average contributions.
