In this case of Hochster v. De La Tour , the representative parties made the contract in April. In this case the defendant agreed that the claimant on a foreign tour should act as his courier, due to begin on 1st June but on 11th may, the defendant informed the claimant that his services would not be required.

It is concluded that when there is a need to end, it is said to be Discharge of contract. For example, when two parties A and B entered into a contract to made a road in Delhi, Where A is the municipal authority of the city and B is a construction company. Still, due to some reasons, the contract has been discharged. Then in this situation, both parties A and B are free from the obligations of the contract, it means when the rights and obligations of the parties come to an end. Various ways or modes were also available for discharging a deal, but the best way to releasing a contract is based on performance. Through this way, both the parties follow all the terms and conditions of the agreement, and then can go for its discharge and on the other side discharge by the breach is the most unpleasant way to release the parties from duties as it leads to damages and compensation too.
