Exhibit “A” is a conditional sale contract dated September 16, 1920, by which the respondent T. W. Little Company agrees to sell to appellant, as equipped, one Model “R” Signal Truck and one 8%-ton Pacific Car and Foundry Company trailer, for the sum of $7,990.10, upon installments, as follows: $3,500 to be paid on the 16th day of September, 1920, and $374 on the 16th day of each month thereafter until the full sum is paid, the title to remain in the vendor, and if any default is made in any payment, or if the vendor at any time deems itself insecure, it may take possession of the property, retain all payments made as liquidated damages, or may sell the property under a mortgage foreclosure and apply the proceeds to any deficiency, and have a deficiency judgment for the balance with allowances for costs, etc., which contract is signed by vendor and vendee.
Exhibit B is identical with exhibit A, except that the [589]*589total amount to be paid under exhibit B is $8,183.04, and installments of $390 are to be paid on the same day, and the last installment is $393.04, and the number of the truck and trailer is different.
To this complaint each of the defendants filed a general demurrer on the ground that the complaint did not state facts sufficient to constitute a cause of action. The lower court sustained these demurrers, and the plaintiff refusing to further plead, the court signed and entered a judgment dismissing the action, and from this judgment the plaintiff appeals to this court.
There is no doubt that as to the first, second, third, fifth and sixth causes of action, as set forth in the complaint of appellant, the demurrers were properly sustained.
The first cause of action was for damages at the rate of $40 per day for 67 days ’ delay in the delivery of one of the trucks. It is contended that it was orally agreed between the parties that the truck would be delivered in ten days, but was not delivered until the time alleged. It is not alleged, however, that there was any protest made when the truck did arrive, and it is shown that appellant executed his written promise to pay for the truck when it arrived and when he received it, apparently without complaint or protest.
The second cause of action is for a kit of tools alleged to have been agreed to be a part of the equipment of the truck, although the written agreement signed by appellant states that he accepts the truck as equipped.
The third cause of action alleged is for $50 because the truck was not delivered at the place where appellant contends it should have been delivered, but it is shown that he received it at the other place, and this would seem to constitute a waiver of the place of delivery.
[590]*590The fifth cause of action is the same as the second, except that it was for another kit of tools on another truck, but the conditions were the same.
The sixth cause of action is the same as the third, except that it applies to another truck; but the conditions of receiving are the same. The trucks alleged in both causes of action were accepted and contracted for in writing.
The orders contained the clause: “No verbal agreement recognized.” When the trucks arrived, the contracts were reduced to writing in the form of conditional sale contracts, which are presumed to contain all the elements of their contracts. Under the allegations as to these causes of action it is plain that they are nothing more than efforts to add oral agreements of the parties and thereby vary the contracts, which cannot be done. Buffalo Pitts Co v. Shriner, 41 Wash. 146, 82 Pac. 1016; Farley v. Letterman, 87 Wash. 641, 152 Pac. 515; Western Farquhar Machinery Co. v. Pierce, 108 Wash. 621, 185 Pac. 570.
As to the failure to deliver the trucks on time, where in each case it was one entire delivery, a vendee’s acceptance of the property in fulfillment of an executory contract of sale is a waiver of objection that it was not delivered at the time agreed, unless his acceptance was qualified by a reservation of the right to claim damages caused by the delay. Minneapolis Threshing Machine Co. v. Hutchins, 65 Minn. 89, 67 N. W. 807; 35 Cyc. 175.
The fourth and seventh causes of action are for damages alleged because appellant was compelled, under duress, to sign the contracts for the purchase of the trucks for a greater amount than the purchase price of the trucks as named in the original orders. These causes of action come near stating causes of action for
[591]*591some relief, but fall short, as we shall presently show. It is to be noted that they contain no allegations that the contracts were signed for the additional amounts over the original orders, under protest, or that the additional amounts have been paid. It would seem that the utmost that appellant could demand in the situation shown, if the contracts varying from the original bargains had been made under protest, would be the reformation of the contracts, if it be conceded that his allegations of duress are sufficient. Without elaborate discussion upon the subject of duress, we have held that the recovery of excessive amounts of money paid under duress, or restraint of goods, by a demandant, will require the return of the money so paid, if paid under protest. Sunset Copper Co. v. Black, 115 Wash. 132, 196 Pac. 640.
We are of the opinion that the situation shown of undue advantage and oppression, and the threats alleged to have been made by the vendor of the trucks to appellant when the trucks arrived were oppressive and coercive; but, in the absence of complaint or protest made at the time, we cannot hold the payments contracted to be made but not made to have been involuntary. The distinction between voluntary and involuntary payments has been very clearly pointed out in many cases. Tripler v. New York, 125 N. Y. 617, 26 N. E. 721; Scholey v. Mumford, 60 N. Y. 498; Bates v. New York Insurance Co., 3 Johns. Cas. (N. Y.) 238; Buckley v. New York, 30 App. Div. 463, 52 N. Y. Supp. 452; Carew v. Rutherford, 106 Mass. 1, 8 Am. Rep. 287; Radich v. Hutchins, 95 U. S. 210.
In the last cited case, Mr. Justice Field stated:
“To constitute the coercion or duress which will be regarded as sufficient to make a payment involuntary, .....there must be some actual or threatened [592]*592exercise of power possessed, or believed to be possessed, by the party exacting or receiving the payment over the person or property of another, from which the latter has no other means of immediate relief than by making the payment.”
In Bates v. New York Insurance Co., supra, it was stated:
“The equitable extension of this kind of action has of late been so liberal, that it will lie to recover money obtained from anyone, by extortion, imposition, oppression, or taking an undue advantage of his situation. In the present case, there was, at least, an undue advantage taken of the plaintiff’s situation..... The money being inequitably demanded of him, he must be presumed to have paid it, relying on his legal remedy to recover it back.”
And in Buckley v. New York, supra, it was said:
“There is no iron-clad rule which confines an involuntary payment to cases of duress of person or restraint of goods. Money compulsorily paid to prevent an injury to one’s property rights comes within the same principle.”
Under these authorities, had appellant paid the sums alleged in his fourth and seventh causes of action in excess of the sums agreed upon to.be paid for the trucks, and under the threats, undue advantages and oppression alléged, on the part of the vendor, under protest at the time, we should say he would be entitled to recover such excess sums so exacted; but, so far as the pleadings show, there was no complaint or protest made at the time, and writings only were executed for the future payments for the trucks in installments. The most that could be said would be that, under such circumstances, had the payments been made under protest and involuntarily, and under such restraint and duress, he would have been entitled to the reformation of the agreements. He has not alleged facts sufficient [593]*593to so entitle Mm in tMs action as to these causes of action.
The judgment is therefore affirmed.
