法院经审理认为，双方最终未能签订正式合同，不能仅归责于被告，应合理推定为磋商不成，故本案不应适用定金罚则，被告无需承担双倍返还定金的违约责任。
After the hearing, the court held that the two parties failing to sign a formal contract could not be attributed only to the defendant, but should be reasonably presumed that the negotiation failed; therefore, the deposit penalty should not be applied in this case, and the defendant should not bear the liability for breach of contract and return twice the deposit.
