Under the Sale of Goods Act, 1930, a contract for the sale of specific goods is void if the goods:

Perish after contracting without fault and before risk passes, yet section 7 itself applies to the later event

Had perished or lost their contractual description through damage, unknown to seller when contracting

Were known by the seller to have perished or lost their contractual description before contracting, so section 7 applies anyway

Were not insured at the time of the contract
