Indian Contract Act Section 34 — When event on which contract is contingent to be deemed impossible, if it is the future conduct of a living person
CHAPTER III OF CONTINGENT CONTRACTS
Commercial / Corporate
Summary
If a contract depends on how a person will behave at some unspecified future time, that event is treated as impossible once the person does something that makes it impossible for them to act that way within any fixed time period, or makes it possible only under additional conditions. In other words, the moment the person's actions rule out the expected behaviour, the contract's condition is considered failed.
Official Text
If the future event on which a contract is contingent is the way in which a person will act at an unspecified time, the event shall be considered to become impossible when such person does anything which renders it impossible that he should so act within any definite time, or otherwise than under further contingencies.
