This is a remand from the United States Supreme Court where various commercial enterprises (taxpayers) claimed Washington's multiple activities exemption to the business and occupation (B & O) tax, RCW 82.04-.440, discriminated against interstate commerce in violation of the commerce clause, U.S. Const. art. 1, § 8. In
Tyler Pipe Indus., Inc. v. Department of
Rev., _ U.S. _,
The decisive issues before this court are whether state law mandates refunds, and if not, whether this is an appropriate case for prospective application. We hold state law does not require refunds, and prospective application is appropriate.
I
State Law
In order to reach the retroactivity issue, this court must first decide if Washington state statutory law or state case law mandates refunds of taxes paid prior to the Supreme Court's Tyler decision. If this state's tax refund statutes, RCW 82.04.4286 and RCW 82.32.060 apply, then all other issues are irrelevant.
This court has stated that, if a tax were in violation of the due process or commerce clauses, it would also be in violation of former RCW 82.04.430(6) (subsequently recodified as RCW 82.04.4286).
Chicago Bridge & Iron Co. v. Department of Rev.,
II
Retroactive or Prospective Application of Tyler
Since Washington law does not foreclose an inquiry into prospective application, we turn to the factors enunciated by the United States Supreme Court to determine whether prospective application is to be afforded in this case.
Chevron Oil Co. v. Huson,
A
New Principle of Law
The threshold factor necessary for prospective application is a finding that the
Tyler
decision established a new principle of law overruling past precedent on which litigants may have relied.
Chevron Oil,
In 1984 the United States Supreme Court invalidated West Virginia's wholesale gross receipts tax because it discriminated against interstate commerce.
Armco Inc. v. Hardesty,
We further held that the "internal consistency" rule is not applicable to a determination of discrimination in a gross receipts tax case. It was our belief that the Court in Armco had used the internal consistency concept only in the determination of whether Armco Inc. had to show actual harm once it had demonstrated the tax was facially discriminatory. For this reason we held the Washington tax *883 was not facially discriminatory, and relied on previous holdings of the United States Supreme Court which had upheld Washington's B & O tax against commerce clause challenges and which were not expressly overruled in Armco.
The Supreme Court held, however, that the multiple activities exemption was facially discriminatory, and that manufacturing and wholesaling are not substantially equivalent activities.
Tyler,
Our unanimous decision in National Can indicates we did not read Armco as foreshadowing the result in Tyler. Taxpayers argue, however, that Armco's reliance on Justice Goldberg's dissent in General Motors clearly informed this court that Washington's tax was unconstitutional. The Supreme Court in Tyler, discussing its Armco decision, said:
In explaining why the tax was discriminatory on its face, we expressly endorsed the reasoning of Justice Goldberg's dissenting opinion in General Motors Corp. v Washington,377 U. S., at 459 . We explained:
"The tax provides that two companies selling tangible property at wholesale in West Virginia will be treated differently depending on whether the taxpayer conducts manufacturing in the State or out of it. Thus, if the property was manufactured in the State, no tax on the sale is imposed. If the property was manufactured out of the State and imported for sale, a tax of 0.27% is imposed on the sale price. See General *884 Motors Corp. v Washington,377 U.S. 436 , 459 (1964) (Goldberg, J., dissenting) (similar provision in Washington, 'on its face, discriminated against interstate wholesale sales to Washington purchasers for it exempted the intrastate sales of locally made products while taxing the competing sales of interstate sellers'); Columbia Steel Co. v. State,30 Wash. 2d 658 , 664,192 P.2d 976 , 979 (1948) (invalidating Washington tax)."467 U. S., at 642 .

Tyler,
Commerce clause challenges to the multiple activities exemption alleging discrimination against interstate commerce have many times been rejected by this court.
See B.F. Goodrich Co. v. State,
long history of the United States Supreme Court's treatment of this state's gross receipts tax as having withstood commerce clause challenges, see Department of Rev. v. Association of Wash. Stevedoring Cos.,435 U.S. 734 ,55 L. Ed. 2d 682 ,98 S. Ct. 1388 (1978); Standard Pressed Steel Co. v. Department of Rev.,419 U.S. 560 ,42 L. Ed. 2d 719 ,95 S. Ct. 706 (1975); General Motors Corp. v. Washington,377 U.S. 436 ,12 L. Ed. 2d 430 ,84 S. Ct. 1564 (1964) . . .
National Can, at 339-40.
We believe Washington's rationale prior to the United States Supreme Court decision in
National Can
was a reasonable assessment of existing case law. In 1983 we held that Washington's B & O tax was not discriminatory under the commerce clause.
Chicago Bridge & Iron Co.,
Also supporting the view that
Tyler
announced new law is Justice Scalia's dissent, which states that the
Tyler
deci
*886
sion "has no basis in the Constitution, and is not required by our past decisions" and that to apply the internal consistency rule, the "Court is compelled to overrule a rather lengthy list of prior decisions".
Tyler,
The holding of Armco thus establishes only that a facially discriminatory taxing scheme that is not internally consistent will not be saved by the claim that in fact no adverse impact on interstate commerce has occurred. To expand that brief discussion into a holding that internal consistency is always required, and thereby to revolutionize the law of state taxation, is remarkable.
(Italics ours.)
Tyler,
Kalama Chemical, representing in-state manufacturers, argues that as to that group Tyler did not enunciate a new principle of law. However, this argument ignores this court's reliance on the concept that selling and manufacturing were believed, until Tyler, to be substantially equivalent and therefore compensatory.
Taxpayers argue that a letter from the Department of Revenue to the Governor shows that the Department of Revenue believed just after the Armco decision that Washington's multiple activities exemption was unconstitutional. The letter from Donald Burrows, Director of Department of Revenue, to Governor John Spellman dated June 14, 1984, expresses the belief that the State faced substantial loss of tax revenue as a result of the Armco decision, and also expressed the likelihood of refunds. This argument is directed to the issue of whether the State justifiably relied on past federal and Washington cases to continue to act under the existing Washington statute.
Such a memorandum discussing an agency director's
*887
opinion of law is, of course, not binding on this court. Even had this opinion been stated in an official agency statutory construction or written in an attorney general opinion, it would not be binding on either the State or this court.
Walthew, Warner, Keefe, Arron, Costello & Thompson v. Department of Rev.,
Even if the director's opinion was that
Armco
placed in question the constitutionality of the B & O tax, it was not within his power to stop collecting taxes under a statute which had been properly enacted by the Legislature. The Department of Revenue was collecting taxes under a statute that had been repeatedly upheld and also enjoyed the presumption of constitutionality. The party challenging the statute would have to prove its invalidity beyond a reasonable doubt.
High Tide Seafoods v. State,
*888
The Department of Revenue may well have relied on the decisions of this court upholding the multiple activities exemption against commerce clause challenges, and there was nothing in the Supreme Court's decisions which clearly overruled this court's analysis until
Tyler
was decided last year. In
St. Francis College v.
Al-Khazraji, _ U.S. _,
B
Commerce Clause Purpose
Since we conclude that Tyler did establish a new principle of law, we must look to see if the purpose of the commerce clause will be furthered or retarded by retroactive application.
The central purpose of the commerce clause is to create an area of free trade among states.
American Trucking Ass'ns v.
Scheiner, _ U.S. __,
It is difficult to understand how retroactive application would encourage free trade among the states since whatever chill was imposed on interstate trade is in the past and the *889 Legislature has enacted law to attempt to comport with the new commerce clause taxation laws announced in Tyler. Laws of 1985, ch. 190; Laws of 1987, 2d Ex. Sess., ch. 3. The Supreme Court has noted that a state has "a significant interest in exacting from interstate commerce its fair share of the cost of state government." Department of Rev. v. Association of Wash. Stevedoring Cos., supra at 748. If this court afforded retroactive application and ordered full refunds, taxpayers engaged in interstate commerce would pay no portion of their share of the tax burden. The multiple activities exemption is now known to be unconstitutional because it imposes the risk of multiple burdens on interstate commerce, but this is not to say that all taxes imposed on a manufacturer or wholesaler under the B & 0 tax were unfair or interfered with free trade among states. The very risk of multiple burdens is now enough (since Tyler) to invalidate the Washington exemption. But, forcing the State to collect no taxes for the entire period of the statute of limitations would be more in the nature of a punitive award for misconstruing the constitutionality of the B & O tax.
Dicta in
Tyler
suggested that the State could continue to tax under the B & 0 statute if the Legislature expanded the multiple activities exemption to provide out-of-state manufacturers with a credit for manufacturing taxes paid to other states.
Tyler,
Therefore, since the purpose of the commerce clause of free trade among the states is not enhanced by retroactive application and the effect of retroactive application would be to relieve some interstate taxpayers of their duty to pay their fair share of the tax burden, we must ask whether retroactivity would be inequitable.
C
Inequity Imposed by Retroactive Application
Taxpayers argue that denying refunds to litigants would discourage challenges to existing precedent. The taxpayers argue
Tyler
should he applied to them because they bore the burden of litigating the issue. They are essentially arguing for what is termed "quasi-prospective" application wherein the new rule applies retroactively to the parties to the overruling decision. Note,
Confusion in Federal Courts: Application of the Chevron Test in Retroactive-Prospective Decisions,
1985 U. Ill. L. Rev. 117. If courts give successful litigants the benefit of the new rule, they have greater incentive to challenge existing rules. However, this singles out the successful litigant for special treatment while applying the old law to other people similarly situated. It also punishes other parties who relied on prior law and then lose in the overruling decision.
Taxpayer Tyler Pipe argues that, because the State argued against an injunction for the collection of taxes pending resolution of the constitutionality of the B & O tax, it now has an absolute right to a refund under the Washington refund statutes. This court denied the requested injunction not only because a remedy at law existed but also because Tyler Pipe failed to make the req
*891
uisite showing of a likelihood of success on the merits.
Tyler Pipe Indus., Inc. v. Department of Rev.,
As the previous list of citations illustrates, many states including Washington have found it equitable to afford only prospective application to decisions invalidating taxing statutes. In Bond v. Burrows, supra, this court invalidated *892 the statutory scheme establishing a sales tax differential for border counties. After determining the tax statute violated the constitutional rule of proportionality, this court unanimously agreed to give the ruling only prospective application. Implicit in Bond is the fact that the court did not apply its decision so as to afford any refunds of past taxes to the counties which had paid higher taxes than the border counties.
Last year in Ashland Oil, Inc. v. Rose, supra, the West Virginia Supreme Court ruled that Armco would be applied prospectively. The West Virginia court determined that the reliance of the state on a presumptively valid tax outweighs injuries sustained on account of a holding of prospectivity.
The State's reliance on the constitutionality of the B
&
O tax was justifiable in light of decisions such as
Tyler Pipe Indus., Inc. v. Department of Rev., supra; National Can Corp. v. Department of Rev.,
We turn now to taxpayers' argument that prospec
*893
tive application would violate due process and equal protection. Prospective application, designed to protect justifiable reliance on prior law and to respect the desire for stability in past transactions, was upheld by the Supreme Court against a due process challenge in 1932 in
Great Northern Ry. v. Sunburst Oil & Ref. Co.,
In
Salorio v. Glaser, supra,
the New Jersey Supreme Court gave pure prospective effect to a decision declaring a tax statute unconstitutional and ruled that the plaintiffs were not entitled to reimbursement of taxes paid. That court held that " [t]he modern view is that invalidation of a statute does not automatically invalidate all prior transactions made in justifiable reliance upon the statute."
Salorio,
The Ashland court recognized that
[ajlthough Lemon II is not a tax refund case and does not therefore provide direct and conclusive authority in this case, it provides the basis for applying the retroac-tivity analysis in the context of protecting state fiscal interests. See also Cipriano v. Houma,395 U.S. 701 ,89 S. Ct. 1897 ,23 L. Ed. 2d 647 (1969) (decision holding unconstitutional Louisiana's property-taxpayer limitation on franchise applied prospectively because retroac-tivity would impose significant hardship on cities, bondholders, etc.)
Ashland Oil, Inc.,
Taxpayers argue that denial of refunds violates equal protection in creating two classes of taxpayers — those whose refund claim is based on the discrimination of the B & O tax against interstate commerce and all others. How
*895
ever, they cite no relevant authority. The body of state and federal law previously cited in the tax area indicates this argument to be without merit. This court held that equal protection forbids all invidious discrimination but does not require identical treatment for all without recognition of difference in relevant circumstances.
Aetna Life Ins. Co. v. Washington Life & Disab. Ins. Guar. Ass'n,
Having weighed the equities in this case, we conclude that pure prospective application from the date of the United States Supreme Court Tyler decision is appropriate, and appellants' claims for refunds before June 23, 1987, are denied.
Pearson, C.J., and Brachtenbach, Dolliver, Dore, Andersen, Callow, Goodloe, and Durham, JJ., concur.
