Mr. and Mrs. Norris Stroud appeal an award of damages under the Consumer Protection Act; Mr. Cordell and Mr. Weber cross-appeal on the issue of damages. We affirm in part and reverse in part.
Mr. and Mrs. Stroud are licensed real estate broker and agent, respectively, and operate a real estate business, United Farm Agency, Inc., on 10 acres adjacent to the Wenatchee/Chelan highway. In February 1980, the Strouds entered into a lease with an option to purchase from Donna Wilson. After the agreement expired on July 31, 1981, the Strouds and Ms. Wilson agreed orally to continue on a month-to-month basis.
In early November 1981, Dennis Weber and his partner, Wayne Cordell, contacted Mr. Stroud at his office. They *863indicated an interest in leasing or purchasing property with highway frontage suitable for a water slide recreational park. Mr. Stroud suggested a possible lease or sale of land surrounding his office. From that initial meeting until March 1982, Mr. Stroud represented the Strouds were the owners of the property.
On December 31, 1981, the Strouds executed an earnest money agreement to purchase the property. A real estate contract was signed on January 22, 1982. The purchase price was $130,000 with credit for rental payments made during 1980-81, for a reduced price of $115,000.
Sometime in January 1982, purchasers researched the chain of title to the property and found no record of the Strouds' ownership. When Mr. Stroud was questioned about the discrepancy, he told purchasers there must have been a mistake since he did in fact own the property.
Both parties understood any sale would be conditioned upon a proper zone change to enable construction of the water slide. Mr. Stroud attended a planning commission meeting on behalf of the purchasers seeking the necessary change. The commission approved the zone change and on March 9, 1982, all three parties signed an earnest money agreement to purchase the property for $195,000. The property was divided into two parcels, parcel A being an outright purchase, and parcel B, a 5-year lease agreement with option to purchase. Shortly after the earnest money agreement was signed, the purchasers received their copy of the preliminary title report which showed the Strouds purchased the property on January 22, 1982. Subsequently, there were several letters exchanged between the parties through their attorneys attempting to renegotiate the purchase price. On June 4, 1982, the purchasers notified the Strouds they were willing to perform under the terms of the earnest money agreement, but the Strouds refused to proceed.
The Superior Court, ruling substantially in favor of the purchasers, awarded specific performance and damages conditioned upon tender by the purchasers of all docu*864ments and money owed under the agreement. In addition, the court found a per se violation of the Consumer Protection Act and awarded $1,000 treble damages, attorney fees and costs. Purchasers failed to tender the necessary documents and money so the judgment was vacated with respect to specific performance and damages, but was confirmed as to the CPA award.
The Strouds first assign error to the finding the violation of the real estate brokers and salesmen act, RCW 18.85.230, constituted a per se violation of the CPA.1 A violation of the CPA may be per se, State v. Reader’s Digest Ass'n, 81 Wn.2d 259, 276, 501 P.2d 290 (1972), or de facto by showing an unfair or deceptive act which affects the public interest, Anhold v. Daniels, 94 Wn.2d 40, 614 P.2d 184 (1980).
In order to establish a per se violation, the conduct must meet a twofold test: (1) it must be illegal, i.e., unlawful; and (2) it must be against public policy as declared by the Legislature or the judiciary. Salois v. Mutual of Omaha Ins. Co., 90 Wn.2d 355, 358, 581 P.2d 1349 (1978).
The first element, illegal action, is established by the Strouds' failure to disclose the ownership of the property, a violation which, under RCW 18.85.230, can be a gross misdemeanor. The second element requires a showing the action is against public policy as declared by the Legislature or the judiciary. In Sato v. Century 21 Ocean Shores Real Estate, 101 Wn.2d 599, 602, 681 P.2d 242 (1984), the court stated:
*865Such a legislative declaration [of a public interest] is not present in RCW 18.85. Compare RCW 18.85.010 et seq. with RCW 48.01.030. In fact, enforcement of RCW 18.85 is placed in the director of licensing, the Attorney General and prosecuting attorney, RCW 18.85.343, .345, .350. Those persons serve the public policy by their enforcement powers.
We conclude therefore, RCW 18.85 does not contain the legislative declaration necessary to give rise to a per se violation of the CPA.
The question remains whether there are compelling reasons to judicially declare this type of conduct contrary to public policy. We must decline to do so. There was no evidence of the public's involvement in this dispute. The property was not listed with the Multiple Listing Service nor were there representations made to the public by other means of advertising. This was a single, isolated transaction. Given the decision of the court in Sato, the proper avenue of redress is through the enforcement powers of the director of licensing, the Attorney General, or the prosecuting attorney.
In the alternative, purchasers argue a de facto violation of the CPA as outlined in Anhold v. Daniels, supra at 46. Therein the court states conduct has an impact on public interest if:
(1) [T]he defendant by unfair or deceptive acts or practices in the conduct of trade or commerce has induced the plaintiff to act or refrain from acting; (2) the plaintiff suffers damage brought about by such action or failure to act; and (3) the defendant's deceptive acts or practices have the potential for repetition.
The case fails to meet the Anhold criteria in that the purchasers did not prove the Strouds' act has the potential for repetition. "In particular, there must be shown a real and substantial potential for repetition, as opposed to a hypothetical possibility of an isolated unfair or deceptive act's being repeated." Eastlake Constr. Co. v. Hess, 102 Wn.2d 30, 52, 686 P.2d 465 (1984). Therefore, we reverse the court's ruling regarding the existence of a violation of the *866CPA and vacate the CPA violation award.
Based on our ruling above, we need not consider the additional CPA issues raised by the Strouds.
The purchasers cross-appeal and assign error to the measure of damages. The Superior Court had ordered specific performance of the earnest money agreement and had awarded $23,600 in damages. The damages represented the Strouds' potential profit less lease payments on parcel B. Purchasers contend the trial court should have assigned them the vendee's interest in the Wilson/Stroud contract; in essence, specific performance with a larger damage award. However, in their supplemental brief on appeal, purchasers ask for alternative damages including (1) $65,000 based on Cogan v. Kidder, Mathews & Segner, Inc., 97 Wn.2d 658, 648 P.2d 875 (1982); (2) liquidated damages of $19,500 as provided for in the earnest money agreement;2 or (3) a minimum of $5,000 damages incurred in reliance.
Counsel indicated in oral argument that a change in the Wenatchee water slide market made specific performance an undesirable measure of relief for purchasers. Therefore, they elected not to avail themselves of the relief of specific performance and damages as first awarded by the trial court. Having failed to appeal the vacation of that judgment, specific performance has become a moot issue. Additionally, we will not address the alternate theories of damages because they were not raised at trial. Purchasers did not ask for such relief in their complaint and raised the issue of alternative damages for the first time in their supplemental brief on appeal. See Sims v. Horton, 43 Wn.2d 907, 264 P.2d 879 (1953); Capper v. Callahan, 39 Wn.2d 882, 239 P.2d 541 (1952). It may well be the trial court would have awarded damages or would have deemed it appropriate to enter judgment other than the requested specific performance, Zastrow v. W.G. Platts, Inc., 57 *867Wn.2d 347, 357 P.2d 162, 360 P.2d 354 (1960); Brazil v. Auburn, 93 Wn.2d 484, 610 P.2d 909 (1980), but it was not asked to do so. The facts in this case warrant a finding that purchasers are entitled to monetary relief. However, the posture of this appeal is such that this court is precluded from granting purchasers the relief they now request without indulging in inappropriate judicial creativity.
The trial court's rulings regarding specific performance and damages are affirmed; its finding the Strouds violated the Consumer Protection Act is reversed, and the purchasers' request for alternative damages for the first time on appeal is denied.
