Appellant, Payette Valley Produce Exchange, through its sales agents, Stewart Branch, entered into a brokerage contract with R.H. Shake and A.C. Patheal, respondents, for their fruit crops. The fruit was delivered to appellant and after deducting all offsets to which appellant was entitled by way of commissions and money advanced, there remained due to respondents on the basis of the price as claimed by respondents to have been fixed, the sum of $2,148.75. Defendant's motion for nonsuit was denied and the jury returned a verdict in favor of respondents.
The written contract provided that appellant was to have the exclusive right to sell, transfer, assign or exchange the produce mentioned for a period of one year, subject to certain conditions, the main provision material in this case being as follows:
"The party of the second part agrees that the party of the first part shall have the sole and exclusive privilege of stating at what time and to whom and at what prices this produce shall be sold."
The written contract did not provide for delivery of the fruit at any specified time. The complaint alleged that at the time of delivery the price was fixed. The answer denied that the respondents designated to whom and at what price the apples should be sold. This was a question of fact for the jury and by their verdict the jury found adversely to appellant. By the terms of the agreement appellant was liable for the purchase price when received, deducting marketing commissions and advances. Respondents had the right to and did fix the price at which the apples were to be sold. Having undertaken to sell and having received the apples under the oral directions completing the written agreement, appellant was bound to sell for that price and was not at liberty to sell at a different price than that specified by respondents. Appellant urges that the price fixing was a guarantee; that is in a way a misnomer, because the undisputed evidence discloses that a definite *Page 407 amount was agreed upon by appellant through its agents and respondents. If there was a guarantee it merely reinforced the obligation already resting on appellant and it is liable because the price was thus fixed substantially as provided for by the contract. (25 C. J., 367, n. 82; Betts v. SouthernCalifornia Fruit Exchange, 144 Cal. 402, 77 P. 993.) There being ample evidence to support the finding of the jury that respondents gave specific directions as to the price, the jury were justified in finding their verdict on this phase of the controversy in favor of respondents.
Appellant urges that it was error to admit in evidence the oral agreement subsequently entered into between the parties for the reason that parol evidence is not permissible to vary the terms of a written agreement. The so-called oral guarantee covering delivery and price was a completion of the written contract and did not in any way vary its terms. Where a contract is incomplete and certain matters are left to be fixed, subsequent oral agreements to complete such written contracts and so intended may be shown. (Wigmore on Evidence, vol. 4, 2441; 22 C. J. 1273, sec. 1693; Dike v. Martin,85 Okl. 103, 204 P. 1106; Shimizu v. Norjiri, 59 Cal. App. 375,211 P. 40; Overstreet v. Merritt, 186 Cal. 494, 200 P. 11.)
It is not disputed that L.V. Stewart and G.W. Branch were general sales agents of the appellant at Payette and had charge of the business in that locality which consisted of the dealing with fruit growers for the season of 1921. Respondents were required and had the right to notify the appellant organization as to the price at which respondents would sell and the dealings between respondents and appellant's agents amounted at least to this. No error is predicated upon the instruction by which the court advised the jury that one question for consideration was: Did the defendant's authorized agents agree upon a price with the plaintiffs for said apples? This instruction was correct and the jury by their verdict found a price had been fixed. Furthermore appellant accepted the benefits of the transaction of its agents after it had knowledge of all the *Page 408 facts and, after suit was instituted by respondents, appellant filing a cross-complaint seeking to retain its commissions on the sale of this fruit. It is well settled that a principal cannot repudiate a contract entered into by its agents in excess of the agents' authority and at the same time accept and retain the benefits that accrue from such act. (Pettengill v.Blackman, 30 Idaho 241, 164 P. 358; Davenport v. Burke,30 Idaho 599, 167 P. 481; Hammitt v. Virginia Mining Co., 32 Idaho 245,181 P. 336.)
The judgment of the lower court is therefore affirmed, and it is so ordered. Costs awarded to respondents.
