Under a contract of sale of 100 barrels of rum made from molasses, 50 barrels were delivered. The buyer pressed for delivery of the remainder but the seller delayed. In the meantime, distillation of spirits from molasses was prohibited by an Act of parliament and all contracts for the sale of such spirits stood annulled. Is the seller liable in damages as having failed to deliver the remaining 50 barrels of rum ?    (5 marks)
