Explanation:

Supervening impossibility refers to a situation where performance of a contract becomes impossible after it has been entered into due to an unforeseen event or change in circumstances. This impossibility must be such that it cannot be avoided or overcome by reasonable means.

Related to Frustration:

Supervening impossibility is related to frustration, as it is one of the grounds for frustration of a contract. Frustration occurs when the performance of a contract becomes impossible or radically different from what was initially contemplated due to an event outside the control of the parties.

Example:

For example, if a person enters into a contract to rent a venue for a wedding reception, but the venue is destroyed by fire before the date of the reception, the contract becomes impossible to perform due to supervening impossibility. The parties are not liable for breach of contract as the performance has become impossible due to an event beyond their control.

Conclusion:

In conclusion, supervening impossibility is a legal doctrine that recognizes that a contract may become impossible to perform due to unforeseen events or changes in circumstances. It is related to frustration of a contract, which is one of the grounds for terminating a contract when performance becomes impossible or radically different from what was initially contemplated.

According to ICA,1872 Sec 56 superveining impossibility will also be called as "doctrine of frustration"
Whereas quid pro quo and privity of contract are related to consideration.
