Before SCHWAB, C.J., and FOLEY and FORT, JJ.
FORT, Judge.
This case arises out of ORS 282.210,[1] which, in effect, grants an economic preference for "all printing, binding and stationery work for the state or any county, city, town, port district, or other political subdivision" by requiring, subject to limitations, that such work "shall be performed within the state."
*658 The facts are not substantially disputed. As summarized from appellants' brief, they establish that on February 7, 1969, defendant Chamberlain, State Printer for Oregon, invited bids for printing Oregon Park folders for the Oregon State Highway Commission. Three bids were submitted as follows:
"1) Graphic Arts Center, a plaintiff herein, $15,300 ($51 per thousand), the printing to be done in the State of Oregon.
"2) Sweeney, Krist & Dimm, $15,720 ($52.40 per thousand), the printing to be done in the State of Oregon.
"3) Met Press Printers, $13,650 ($45.50 per thousand), the printing to be done in the State of Washington."
The bids were opened at the proper time. Defendant Chamberlain determined the contract should go to the low bidder, Met Press, because "the more than 10% difference between the two lowest bids is sufficient justification for placing the order with the out-of-state firm." Subsequently defendant Ott, then Director of Department of General Services, after "a full review of this bid," upheld and approved the decision of Mr. Chamberlain on the ground that the latter's "discretion was properly exercised and was in compliance with the spirit and letter of the law." The contract was duly awarded to Met Press.
Thereafter plaintiffs filed this suit to enjoin the actions of the defendants by restraining the payment of any funds to Met Press and enjoining the defendants from accepting delivery of the folders.
The evidence at trial showed that the successful Oregon bidder during the two previous years had lost money on each year's folder contract, that the low Oregon bidder for the 1969 folder contract would have charged any private concern $16,500 for the work but charged the state only $15,300 under its bid, and that the latter estimated making only $200 "gross profit" had it been awarded the 1969 contract. It was undisputed that all three bidders had the capacity to produce the folders in accordance with the specifications.
The trial court, after hearing the testimony, found that "the defendant John R. Chamberlain, the State Printer, was acting within the scope of his authority when he accepted the bid for the work in question and the evidence substantiates the fact that he did not abuse his discretion nor the statutory guidelines as set forth in ORS 282.210," and entered its decree accordingly dismissing the complaint. Plaintiffs appeal.
Mr. Chamberlain testified:
"In this particular instance the difference in cost between the lowest and the next lowest bid is the basis on which I accepted the bid."
The amount of this difference was "slightly under 12 per cent" and represented a saving to the state of $1,650.
Appellants' reply brief states:
"Plaintiffs' position is straightforward. It presents the issue of this case: Does price differential alone satisfy the legislative guidelines as set forth in ORS 282.210? * * *"
It contends, of course, that the answer is that it does not.
ORS 282.210 was adopted in 1931. It has not been amended. Twenty years later, by Oregon Laws 1951, ch. 439, the legislature adopted a general act which created the Department of Finance and Administration (now Department of General Services), and dealt exhaustively with matters of general administration of state affairs. Among its provisions were directives concerning the requirement of competitive bids for purchase of stated supplies, ORS 279.714, and the awarding of contracts based on such bids to the lowest responsible bidder, ORS 279.726. Authority over such matters was vested thereby in the Department of Finance and Administration. Sections 36 and 38 of the 1951 Act, now combined in ORS 279.714, require competitive bidding, and Section 39, now ORS 279.726, requires awarding of *659 contracts governed by the Act to the "lowest responsible bidder taking into consideration quality, probability of performance, and in the case of lease and rental agreements, condition and location of premises."
Whether it was the intention of the legislature by the enactment of Oregon Laws 1951, ch. 439, to effect a repeal by implication of the preferential treatment accorded by it to printers, binders and stationers, for work "performed within the state [of Oregon]" in the 1931 Act, now ORS 282.210 to 282.230, has not been directly presented to us. In the view we take of this case it is not necessary for us to decide it. We therefore do not consider it.
Our attention has not been called to, nor have we found, any decision of our Supreme Court which construes ORS 282.210(2)(c). In Hanson v. Mosser, 247 Or. 1, 427 P.2d 97 (1967), the Supreme Court had occasion to discuss ORS 279.726 in connection with the purchase by the state of some safes and the extent of the authority of the director of Finance and Administration thereunder. Although the case was decided on a question of pleading, the court did say at 9-10, 427 P.2d at 101:
"In Inge v. Board of Public Works of Mobile, 135 Ala. 187, 198-199, 33 So. 678, 681, 93 Am.St.Rep. 20 (1902), the Supreme Court of Alabama in a well-reasoned opinion stated:
"`* * * "The determination of who is the lowest bidder, with the qualification of responsibility, rests not in the exercise of an arbitrary, unlimited discretion of the officer or board awarding the contract, but upon the exercise of a bona fide judgment, based upon facts tending reasonably to the support of such determination." * * * In the absence of fraud or gross abuse, the courts will not interfere with the exercise of discretion by administrative boards or officers in their determination of who is the lowest responsible bidder. * * *'"
It then stated at 12, 427 P.2d at 102:
"* * * If the evidence shows, however, that the award was made in a legitimate exercise of the broad discretion of which the Director of the Department of Finance and Administration is possessed, his act would be fully authorized by the state * * *."
The statute clearly allows the awarding of a bid to one who will not perform the work in the state of Oregon when the bids "are excessive and not reasonably competitive." ORS 282.210(2) (c).
The statute provides no definition of "excessive" nor establishes guidelines as to what is meant by "reasonably competitive." Clearly then the Director of the Department of General Services here, too, is required to exercise the "broad discretion" requisite to determination of whether a bid, which, as here, is not the low bid, is "excessive and not reasonably competitive."
Where, as here, such bid exceeds by approximately 12 per cent that of the lowest bidder, we cannot say that the discretion vested in the Director has been abused in concluding that it was excessive.
Finally, appellants contend that even though Graphic Arts' bid was excessive, this does not mean it was not reasonably competitive. It may be true, as appellants contend, that a bid found to be excessive may be reasonably competitive within the intendment of the statute under special circumstances, such as, for example, those alluded to in ORS 282.230. It does not, however, follow that it is an abuse of discretion to conclude that a price excessive by more than ten per cent is, standing alone, not a reasonably competitive price. Abuse of discretion is never presumed. On the contrary, ORS 41.360(15) informs us that the presumption is that "official duty has been regularly performed."
Plaintiffs do not claim, and the record is devoid of showing, circumstances, whether those described in ORS 282.230 or otherwise, which establish an abuse of discretion by the defendants in concluding that *660 since plaintiff's bid was excessive it likewise was not reasonably competitive.
We think the trial court correctly concluded that the defendants did not abuse the discretion vested in them by the statute in question.
The judgment is affirmed.
