In the case of Harvey v. Facey it was held

Solution

It was observed by the Privy Council that there never existed an agreement between the parties to the case and it also stated that for a contract to be a valid one, a proposal and the acceptance of the proposal are needed so as to make the contract binding on the parties. Mere reply of a query is not an acceptance. Apart from this, the acceptance of the proposal must be notified to the individual who is making the proposal because a legally enforceable agreement requires certainty to hold from both the parties to the contract.
