CASE: When parts are received from vendors, they are accompanied by an invoice. Mrs. Gauron in the Receiving Department checks the invoice against the order file to be certain that the correct parts were delivered. If the parts were not ordered or the order was incorrectly filled, the parts are returned. If the parts are correct, the inventory file is updated to reflect the new quantity for these parts. Mrs. Gauron then prepares the payment for the vendor. She also enters the payment transaction in the general ledger, which is maintained as a bound accounting ledger. A worker on the factory floor who needs a part requests it by submitting a requisition to the part clerk. The information on this form is used to update the inventory file. Each week, the part clerk uses the inventory file to prepare a report. For parts listed on the report, a purchase request form is prepared and sent to the purchasing office.

Alandowner entered into a written agreement with a real estate broker whereby the broker would receive a commission of 10% of the sale price if he procured a "ready, willing, and able buyer" for the landowner's property and if the sale actually proceeded through closing. the broker found a buyer who agreed in writing to buy the property from the landowner for $100,000, the landowner's asking price. the buyer put up $6,000 as a down payment. the agreement between the landowner and the buyer contained a liquidated damages clause providing that, if the buyer defaulted by failing to tender the balance due of $94,000 at the closing date, damages would be 10% of the purchase price. the landowner included that clause because she was counting on using the proceeds of the sale for a business venture that would likely net her at least $10,000. the buyer became seriously ill and defaulted. when he recovered, he demanded that the landowner return his $6,000, and the landowner refused. the broker also demanded the $6,000 from the landowner and was refused. the broker and the buyer filed separate suits against the landowner, with the buyer pleading impossibility of performance. the two cases are consolidated into a single case. how should the court rule as to the disposition of the $6,000?
