Facts of Hartley v Ponsonby
There were 37 crew members on a ship which was returning to UK. Ponsonby , the Defendant, was the sailor of the ship. When the ship was on its way, 17 of the crew members left.
By this the Ship came in danger and it was becoming un-controllable to handle. The Defendant promised the rest of the crew members that if they help him get the ship back to uk by doing the work of the rest of the workers. He will pay them extra wages.
To this the crew members relied and did more than what they were obliged to do, When the ship reached back to U.K the sailor refused to pay them more. The Cliamant sued the sailor for price.
