Okla. Stat. tit. 12A, § 12A-2-613: Casualty to Identified Goods

Where the contract requires for its performance goods identified

when the contract is made, and the goods suffer casualty without

fault of either party before the risk of loss passes to the buyer,

or in a proper case under a "no arrival, no sale" term (Section 2-

324) then

(a) if the loss is total the contract is avoided; and

(b) if the loss is partial or the goods have so

deteriorated as no longer to conform to the contract the buyer may

nevertheless demand inspection and at his option either treat the

contract as avoided or accept the goods with due allowance from the

contract price for the deterioration or the deficiency in quantity

but without further right against the seller.
