Core Legal Answer & Context: This scenario involves a condition attached to a lease that is physically impossible to perform. Under the Indian Contract Act, 1872, an agreement to do an act impossible in itself is void (Section 56). While the Transfer of Property Act, 1882, deals with conditions in transfers, the underlying impossibility of the condition renders the entire agreement, including the lease, void from the outset. A condition that is impossible to fulfill cannot form a valid basis for a contractual obligation or a transfer of interest, making the agreement unenforceable.

Relevant Statutes and Sections: Indian Contract Act, 1872, Section 56 (Agreement to do impossible act).

Important Landmark Cases: Not applicable for such a clear case of impossibility.

Clear Conclusion: The lease is void.
