Strelecki v. Oklahoma Tax Commission

872 P.2d 910, 1993 WL 379008

Opinions

OPALA, Justice.-

The issue urged upon us on review is whether the new rule of federal law announced in Davis v. Michigan Dept, of Treasury1 applies retroactively to require refunds — on Taxpayers’ timely claims for a correct amount — of state income tax overpay-ments on Taxpayers’ federal retirement income excludable under Davis? We answer in the affirmative. The U.S. Supreme Court’s recent jurisprudence in Harper v. Virginia Dept, of Taxation2 — which applies the retroactivity analysis of James B. Beam Distilling Co. v. Georgia3 — mandates retroactive application of the nondiscrimination principle announced in Davis. State law affords these Taxpayers the remedy they seek.

I

THE ANATOMY OF LITIGATION

The appellants [Taxpayers] are retired federal employees who received income from the United States during the years of 1985 through 1988 either as retired civil service employees or retired military personnel. During this period Taxpayers paid state taxes under Oklahoma income tax laws whose provisions subjected a portion of their civil service or military retirement income to state income tax while exempting from like taxation the retirement income of former state employees.⁴ On March 28, 1989 the U.S. Supreme Court held in Davis a similar taxing scheme invalid.⁵ Following Davis, Taxpayers timely filed amended returns, claiming refund of voluntary overpayments of income tax for four years, 1985 through 1988, both inclusive — a period which represents the time immediately preceding the Davis opinion.⁶ Responding to Davis, the Oklahoma Legislature provided by its 1989 amendment identical tax treatment for both state and federal retirement income.⁷ The General Counsel of the Oklahoma Tax Commission [Commission] opined that Davis must be given'purely prospective application. On the basis of this advice the Commission’s Income Tax Division denied Taxpayers’ refund claims 8

Taxpayers timely protested and demanded- a hearing before the Commission.⁹ The Income Tax Division stipulated that (a) the claims were timely and the amounts claimed for refunding comet and (b) the final determination of the legal issues presented by these claims would govern all similarly situated taxpayers who have timely sought a refund.¹⁰ An administrative law judge found that the pre-1989 Oklahoma tax scheme was not in any significant way different from the taxation regime condemned in Davis. By applying the guidelines of Chevron Oil Co. v. Huson,¹¹ the judge concluded that Davis must be given purely prospective application. The Commission adopted this recommendation and denied the claims.12 Taxpayers appeal.¹³ The dispositive issue pressed on appeal is whether we must apply Davis retroactively. This question, answered mid-appeal by the U.S. Supreme Court in Harper,14 will be discussed in Part III. Harper mandates that the Davis’ teachings be extended to these Taxpayers.

II

THE DAVIS v. MICHIGAN DEPT. OF TREASURY¹⁵ PRINCIPLE OF NONDISCRIMINATION

The Court in Davis reviewed a Michigan statute that exempted from state taxation all benefits paid by the state to its retired employees but taxed like benefits received from other employers, including the federal government. After paying state income taxes on his federal retirement benefits for several years, Paul Davis, a retired federal government employee and Michigan resident, challenged the state tax law as infirm. He argued that the disparate treatment of state and federal retirement benefits discriminated against federal retirees in violation of a U.S. statute, 4 U.S.C. § 111.¹⁶ The Michigan court upheld the state law. The U.S. Supreme Court struck it as invalid, holding the state tax statute violative both of § 111 and of the constitutional doctrine of intergovernmental tax immunity embodied in the Supremacy Clause of the U.S. Constitution.¹⁷ After acknowledging the state’s concession that a refund would be appropriate in the face of an adverse ruling, the Court stated that Davis would be due a refund. Its pronouncement neither discussed nor reserved for a later decision the temporal point of Davis’ effectiveness.¹⁸

THE RETROACTIVITY ANALYSIS OF HARPER V. VIRGINIA DEPT. OF TAXATION¹⁹

The Virginia tax scheme, like that of Michigan and Oklahoma, exempted from state income taxation the retirement benefits of state and local government employees while levying an income tax on federal retirement benefits. Responding to the Davis command, Virginia repealed its preferential tax regime for state and local government employees. Petitioners, federal civil service and military retirees, sought a refund of taxes assessed by Virginia before the revision of its statutory scheme to meet the Davis criteria. The Virginia Supreme Court denied relief to the petitioners,²⁰ concluding that Davis should not be applied retroactively in the light of Chevron²¹ and American Trucking Assns, Inc. v. Smith.22 On certiorari, the U.S. Supreme Court ordered the Virginia Supreme Court to re-examine the petitioners’ claim in keeping with its then recent pronouncement in Be am.²³ Beam requires that a new federal rule have a retroactive application to claims arising from facts predating its decisional promulgation.²⁴ The Virginia court reaffirmed its own previous decision,²⁵ holding that Beam did not foreclose the continued use of the three-part Chevron²⁶ test because Davis did not expressly decide whether its rule applied retroactively.

The U.S. Supreme Court granted certiora-ri a second time, reversing the Virginia judgment and giving retroactive effect to the nondiscrimination principle of Davis.27’’ The Court followed the retroactivity analysis in Beam: a new rule of federal law announced by the U.S. Supreme Court and applied to the parties before it in a civil action must be given full retroactive effect in all cases still open on direct review and as to all events that are not time-barred (capable of being litigated), regardless of whether they predate or postdate the announcement of the rule (the so-called “pipeline rule”).²⁸ This rule “extend[ed] Griffith’s ban against ‘selective application of new rules’ ” to criminal cases.²⁹

The General Rule of Retroactivity— Its Birth, Erosion and Revival

The Court notes in Harper that both the common law and its own jurisprudence have long recognized a general rule of retroactivity for its constitutional decisions.³⁰ This principle was eroded in Linkletter v. Walker ³¹ where the Court developed a three-part

test under which it could confine a new rule of criminal law to prospective application.³² In the civil context, Chevron similarly permitted the withholding of retroactive effect to a new principle of law.³³ Linkletter was overruled in Griffith v. Kentucky³⁴ where the Court eliminated all limits on retroactivity of a new criminal-law rule. Griffith’s teachings rest on (1) “basic norms of constitutional adjudication” — i.e., a selective application of new rules violates the principle of treating similarly situated parties the same — and (2) “the nature of judicial review,” which strips the Court of the legislative prerogative to make rules of law retroactive or prospective as it sees fit.³⁵

Griffith dicta — that “civil retroactivity ... continues to be governed by the standard announced in Chevron”36 — left the issue unsettled for civil cases. The Court confronted in Smith³⁷ the meaning of its Griffith dicta. Smith was a plurality opinion in which the Court considered whether to confine the application of a civil-law rule announced in an earlier ease to events which predate that decision.³⁸ While in Smith the Court was split, its later opinion in Beam adopted a principle requiring retroactive application of a new civil-law (noncriminal) rule that was applied to the parties in the case in which it was announced.

Beam’s Implied Retroactivity Analysis³⁹

Harper, which governs us here, gave controlling ejfect to Beam’s retroactivity jurisprudence. The issue in Beam was whether the new constitutional rule announced in Bacchus Imports, Ltd. v. Dias40 should apply retroactively. Bacchus had held a Hawaiian statute violative of the Commerce Clause.⁴¹ The offending state enactment imposed a higher excise tax on imported alcoholic products than on those produced within the state. Bacchus applied the new rule to the parties before it, but was silent as to the opinion’s backward or forward reach. Following Bacchus, the James B. Beam Distilling Company sought a refund of taxes imposed on alcoholic beverages by a Georgia statute similar to that condemned in Bacchus. The state court struck the Georgia law, but after using a Chevron analysis, refused to give Bacchus the sought-for retroactive effect.⁴² On certiorari, the U.S. Supreme Court’s plurality reversed the Georgia judgment, declaring that the state court had erred in refusing to give retroactivity to a previously announced federal-law rule which had been applied to the litigants in the prior case.⁴³ Beam, whose retroactivity teaching garnered six votes, holds that retro-activity is the general rule of constitutional jurisprudence.⁴⁴ In the aftermath of Beam and until Harper was pronounced, state courts were divided on whether retroactivity may be implied when the U.S. Supreme Court’s decision has not squarely addressed the issue.⁴⁵

Harper concludes that when the “Court does not ‘reserve the question whether its holding should be applied to the parties before it,’ ... an opinion announcing a rule of federal law ‘is properly understood to have followed the normal rule of retroactive application’ and must be ‘read to hold ... that its rule should apply retroactively to the litigants then before the Court.’”⁴⁶ Moreover, “the legal imperative ‘to apply a rule of federal law retroactively after the case announcing the rule has already done so’ must ‘prevail!] over any claim based on a Chevron Oil analysis.’ ”⁴⁷

IV

OKLAHOMA’S PRE-1989 TAX SCHEME

Our task here is to examine the pre-1989 statutory tax scheme in contest below.⁴⁸ The Commission, qua administrative agency, is powerless to strike down a statute for constitutional repugnancy. Within the framework of Oklahoma’s tripartite distribution of government powers, the authority to invalidate a constitutionally infirm enactment resides solely in the judicial department.⁴⁹ Every statute is hence presumed constitutionally valid until a court of competent jurisdiction has declared otherwise. The Income Tax Division stipulated below, and the Commission found, that no significant legal distinction exists between Oklahoma’s income tax scheme in effect for the tax years 1985 through 1988 and the condemned Michigan tax-law regime invalidated in Davis. The plain teachings of Davis and Harper command us today to hold the pre-1989 income tax framework invalid insofar as it discriminated against federal retirees’ income and, in conformity to the strictures of Harper, give retroactive effect to Davis.

V

THE TAXPAYERS’ REFUND REMEDY

A.

Refund Claims For Pre-Davis and Post-Davis Overpayments

The Commission asserts that two kinds of taxpayer claims are involved in this case and the law applicable to each is different. The first category is taxpayer Worrell’s refund claim for a post-Davis overpayment made under protest of additional taxes proposed to be assessed on his 1988 return. Because Worrell availed himself of the statutory protest procedure to his protest Davis is acknowledged to apply retroactively.⁵⁰ This much only the Commission is willing to concede in its post-Harper advocacy. For the other category of claims — i.e., refund claims for pre-Davis voluntary overpayment of taxes without protest — the Commission argues that a refund is neither required by federal due process strictures nor available under Oklahoma law. In essence, the Commission’s post-Harper position is that all pre-Dams overpayments are nonrefundable unless made under protest. For the reasons stated in Part V(D) and (E), we reject this argument as contrary to Harper⁵¹ and to the notions of due process in Art. 2, § 7, Okl. Const.52

B.

The Commission May Not Be Relieved Of Its Pre-Harper Procedural Posture

After Harper. declared Davis retroactive, Taxpayers sought “summary reversal” of the Commission’s denial of their refund claims. This court directed the parties to show cause why in disposing of this case we should not hold the Commission bound by the unequivocal terms of its pr e-Harper stipulations below.⁵³

The Commission responded that its stipulations were merely “for pre-hearing housekeeping purposes”. According to the Commission, a refund of taxes is neither mandated by the teachings of Harper nor required by state law when the tax was voluntarily paid without protest under a statute later declared unconstitutional. Taxpayers characterize the Commission’s post-Harper argument as “new-found” and a “last gasp effort at the eleventh hour”.

Our review of the record indicates that the Commission’s pr e-Harper and post -Harper positions on two critical issues are vastly different and materially inconsistent. First, the Income Tax Division asserted in its pre-hearing “position memorandum” filed below that the issue is whether Davis is to “apply retroactively to require the Oklahoma Tax Commission to refund or exclude taxes paid on federal retirement income for [the tax] years 1984,1985, 1986,1987 and 1988.”⁵⁴ Its post-hearing brief similarly states that the “taxpayers will be entitled to a refund or abatement of the taxes in question, if, and only if, the decision in Davis is to have retroactive effect.”⁵⁵ The Commission’s pre-Harper answer brief on appeal unequivocally articulates the same proposition,⁵⁶

The second inconsistency is found in materials attached to the Income Tax Division’s pre-hearing brief filed below in support of its objection to taxpayer Worrell’s quest for suspension of Commission proceedings until the termination of his district court action for refund. These materials included a motion to dismiss and a brief the Commission had filed in Worrell’s district court case.⁵⁷ In its district court brief the Commission had argued that the Uniform Tax Procedure Code⁵⁸ provides the exclusive “remedies and procedures for taxpayers to challenge allegedly illegal or unconstitutional taxes, and for the recovery or refund of such taxes already paid.”⁵⁹ The brief informed the district court that three statutory remedies are available. When the Commission proposes to assess additional or delinquent taxes against a taxpayer and the taxpayer complains that the tax is illegal, the taxpayer can either (1) protest the assessment and receive a full hearing⁶⁰ (2) or pay the tax under protest and give notice of his intent to file suit in the district court.⁶¹ But where “a taxpayer has voluntarily reported and paid his taxes without protest, and the tax is subsequently found to be illegal or unconstitutional, the taxpayer has a different remedy. The taxpayer must file a claim for refund with the Tax Commission, and he is prechided from resorting to the courts until a final Commission order is entered on his claim.”62 In support of this last remedy the Commission’s brief cited and relied upon two Oklahoma decisions⁶³ and the provisions of 68 O.S.1981 § 2373.⁶⁴ This statement materially differs from the assertions in the Commission’s post-Harper supplemental appellate brief. In the latter document counsel represents that Oklahoma’s statutory scheme provides only two statutory remedies for a refund of taxes paid under an unconstitutional taxing scheme. Implicit in this post-Harper argument is the notion that state law leaves the Commission without authority to refund voluntary overpayments (tax paid without protest) of income tax.

A party on appeal cannot take a position inconsistent with that maintained before a trial tribunal.⁶⁵ While this court may decide a public-law case on dispositive issues,⁶⁶ it will not relieve a party of a solemn commitment to a position argued both below and on appeal unless it is so contrary to the applicable law that it would amount to an ultra vires act.⁶⁷ We hence hold that the Commission is bound in this case (1) by the Income Tax Division’s pre-Harper position, below and on appeal, that Taxpayers are entitled to a refund of overpayment if Davis is retroactive, and (2) by its procedural posture below that the statutory scheme does allow Taxpayers to seek a timely refund of taxes voluntarily paid under a clearly unconstitutional statute. The Commission now attempts to relitigate the remedial correctness of the refund claims on inconsistent theories. It has lulled these Taxpayers into a false sense of security by inducing their belief that the voluntary over-payments claimed to be due would be refunded if Harper gave retroactive effect to Davis. The Commission will not be heard — at this late hour — to deny liability upon a changed interpretation of the state’s remedial regime for refunds. The government stands before us on the footing of an ordinary appellee. It will not receive a more favorable treatment than that afforded other appellate litigants in a similar situation.

Even if we assumed that legislative silence on refundability of voluntary income tax overpayments operates as a bar to the Commission’s consideration of such claims (and hence points to its lack of authority to maintain the pre-Harper position), the refund bar the Commission urges against claims of pre-Davis voluntary overpayment would be constitutionally infirm.

C.

The Commission’s Construction Would Nullify or Render Meaningless an Overpaying Taxpayer’s Statutory Opportunity to Amend an Income Tax Return

Assuming for argument’s sake the Commission is correct that a person voluntarily overpaying income tax may not seek a refund, its position would be inconsistent with a taxpayer’s ■ § 2375 statutory opportunity to amend upward or downward an incorrect income tax return.⁶⁸ Under the Commission’s construction of the remedial regime for refundability, a downward amendment would be but a vain exercise because only an upward amendment could become effective. Amended returns, if they were to show overpayment, would be for naught, but the government could collect if any amendment were to reflect underpayment. This interpretation would give § 2373 an absurd meaning. A taxpayer could amend a return, but unless the self-assessed tax due had been underpaid, he could never benefit from the corrected return. It would be indeed absurd for us to hold that, though a taxpayer may amend a return, he/she can never recapture any overpayment, no matter how timely the refund was sought.

It is a well-settled principle of statutory construction that, where possible, courts will not allow statutes to have absurd or discriminatory consequences. Construction that would lead to an absurdity or to discriminatory treatment will be avoided if this can be done without violating legislative intent.⁶⁹ In order to give § 2373 its intended effect, we must adopt the meaning that would uphold its constitutionality.⁷⁰ In this resolve we are also supported by the law’s command that tax statutes be strictly construed against the state.⁷¹ Any doubt as to their possible meaning must be resolved in favor of the taxpayer.⁷²

D.

The Statutory Construction of Oklahoma’s Remedial Regime For Tax Refunds, which the Commission Urges For Our Adoption, Would Make The Regime Vulnerable To a Due Process Attack

The Commission’s post-Harper briefs argue for the first time on appeal that Taxpayers did not invoke the several remedies that were available. The uninvoked remedies, which we are told meet the Harper federal due process requirements, are (a) two statutory remedies (not three as asserted in the district court)⁷³ which may be pursued when the Commission proposes to assess an illegal or unconstitutional tax, (b) in cases where no assessment has been proposed, no Commission order issued, and no taxes are due, a declaratory action would lie to challenge the constitutionality of a tax to which a taxpayer is subject,⁷⁴ and (e) a prerogative writ could be sought to enjoin the collection of taxes determined to be unconstitutional.⁷⁵

The Commission asserts that nothing in the applicable income tax refund statute, § 2373,⁷⁶ provides guidance to identifying the specific grounds on which a refund may be due. In the face of legislative silence, the Commission concludes that it is not unreasonable to assume the state has not provided for any relief beyond that necessarily imposed by federal due process. By drawing an analogy to the general statute, 68 O.S.1981 § 227, which provides for refunding of taxes “erroneously paid through error of fact, or computation, or misinterpretation of law, ”⁷⁷ the Commission concludes that there is no authority for refunding voluntary income tax overpayments made before Davis.

We cannot accede to the Commission’s § 2373 analysis — that under our system of self-assessment for income tax liability, taxpayers who voluntarily overpay on the assumption that no exemption applies do so at their own peril. In our view, § 2373 does not bar refund to taxpayers who voluntarily overpaid under presumptively valid statutes and then timely made refund claims after a judicial pronouncement of the statute’s infirmity. To hold otherwise would violate the anti-discrimination component of our state constitution’s due process clause.⁷⁸ The construction pressed upon us would make a pre-Davis voluntary overpayment perpetually irremediable. Where there are two possible interpretations of a statute, only one of which would render the enactment unconstitutional, the court should follow that which upholds the validity of legislative law.⁷⁹ The fundamental law’s command would indeed be violated if we were to construe § 2373’s silence as erecting an insuperable bar to refundability of voluntary overpayments. We hence adopt today that construction' which ensures the refund regime’s constitutionality.

E.

The Due Process Teachings of Harper

In Harper the Court observes that the constitutional sufficiency of any refund remedy initially turns on whether state law provides an adequate form of “ ‘predeprivation process,’ for example, by authorizing taxpayers to bring suit to enjoin imposition of a tax prior to its payment, or by allowing taxpayers to withhold payment and then interpose their objections as defenses in a tax enforcement proceeding.”⁸⁰

What the High Court doubtless meant by its quoted language is that the taxpayer must be afforded an adequate opportunity to secure relief from the burden imposed by a constitutionally infirm tax statute. Were we to accept the Commission’s argument, consideration would be foreclosed to all refund claims based on overpayment caused by a yet undeclared constitutional infirmity in the state tax structure. The urged-for construction clearly would make our law vulnerable to a due process attack. Taxpayers would be subjected to an incontestable loss of property contrary to the Court-declared state obligation. “[T]he Due Process Clause of the Fourteenth Amendment obligates the State to provide meaningful backward-looking relief to rectify any unconstitutional deprivation. ... In providing such relief, a State may either award full refunds to those burdened by an unlawful tax or issue some other order that ‘create[s] in hindsight a nondiscriminatory scheme. ’ ”⁸¹ (Emphasis ours.)

SUMMARY

Because Harper mandates that Davis be applied retroactively, Taxpayers are entitled to the refund they seek. The Income Tax Division stipulated below to the correctness and timeliness of the refund claims here in contest and retained this position until its post-Harper change of mind. For the reasons stated in the opinion, the Commission must be held bound by its earlier position. We hence remand this cause to the agency whence it came with directions to allow Taxpayers’ timely refund claims together with such interest,⁸² if any, that is their due under the applicable state law.⁸³ Today’s pronouncement addresses only the rights of the six Taxpayers before us. We express no opinion on the timeliness or correctness of any other claims for refund.

The legislature eliminated the quoted provisions of § 923 in 1989 (Okl.Sess.L.1989, Ch. 249, § 44, eff. Jan. 1, 1989).

In contrast, 68 O.S.Supp.1982 § 2358(C)(9) of the Oklahoma Income Tax Act provided:

“For all tax yéars beginning after December 31, 1981, taxable income and adjusted gross income shall be adjusted to arrive at Oklahoma taxable income and Oklahoma adjusted gross income as required by this section.

(9) Retirement benefits not to exceed Four Thousand Dollars ($4,000.00), which are received by an individual from the civil service of the United States, shall be exempt from taxable income.” (Emphasis added.)

The quoted provisions of 68 O.S.Supp.1982 § 2358(C)(9) were amended in 1989 (Okl.Sess.L. 1989, Ch. 249, § 39, eff. Jan. 1, 1989). The pertinent terms of 68 O.S.Supp.1989 § 2358(D)(9) are:

“9. Retirement benefits not to exceed Five Thousand Five Hundred Dollars ($5,500.00), which are received by an individual from the civil service of the United States, any component of the Armed Forces of the United States, the Oklahoma Public Employees Retirement System ... shall be exempt from taxable income.”

The quoted language was not changed by the 1990, 1991 or 1992 amendments. .

5 . The Income Tax Division stipulated that, prior to its amendment in 1989, the Oklahoma income tax scheme was not legally different in any significant manner from Michigan's tax regime which the Court declared invalid in Davis, supra note 1. See Record pages 6, 494.

6 . Only refunds for the years 1985 through 1988 were sought. Taxes had been assessed for the years 1985-1987 when Davis was handed down on March 28, 1989. Claims for refund of taxes paid for the years before 1985 were conceded to be time barred under the applicable statute of limitations. See 68 O.S.1981 § 2373, infra note 64.

The administrative law judge found that Taxpayers submitted the following income tax refund claims:

1) Mr. Strelecki’s claim is for the period of January 1, 1985 through December 31, 1985 in the total amount of $1,534.00. This represents the amount of Oklahoma income tax paid on his military retirement income received in 1985.

2) Mr. and Mrs. Lankford's claims are for the periods of January 1, 1985 through December 31, 1985; January 1, 1986 through December 31, 1986; January 1, 1987 through December 31, 1987; and January 1, 1988 through December 31, 1988. The total amount sought was $8,491.00. This represents the amount of Oklahoma income tax paid on the civil service retirement income received by them during these years.

3) Mr. Worrell's claims are for the periods of January 1, 1985 through December 31, 1985; January 1, 1986 through December 31, 1986; January 1, 1987 through December 31, 1987; January 1, 1988 through December 31, 1988. During this four-year period, he paid a total of $7,229.00 in taxes on his civil service retirement income. Mr. Worrell had filed a refund claim for voluntary overpayments on his returns for the years 1985 through 1987; he also paid under protest the assessment of his 1988 taxes.

4) Mr. and Mrs. Harris’ claim is for the period of January 1, 1985 through December 31, 1985 in the total amount of $977.00. This represents the amount of Oklahoma income tax paid on the military retirement income received by them during 1985.

44 . Beam, supra note 3, 501 U.S. at -, 111 S.Ct. at 2445. Beam was doubtless aimed at assuaging criticism leveled at the Court by academic lawyers for its pre-Beam brand of pros-pectivity that was causing a serious disparate impact on similarly situated individuals. See De-Long, Confusion In Federal Courts: Application Of The Chevron Test In Retroactive-Prospective Decisions, 1985 Univ. of Ill.L.Rev. 117, 125-132; Beytagh, Ten Years Of Non-Retroactivity: A Critique And A Proposal, 61 Vir.L.Rev. 1557, 1596, 1602, 1612-13, 1616 (1975); Fairchild, Limitation Of New Judge-Made Law To Prospective Effect Only: "Prospective Overruling” or "Sunbursting”, 51 Mar.L.Rev. 254, 267 (1967-1968); Keeton, Creative Continuity In The Law Of Torts, 75 Har.L.Rev. 463, 491 (1962); Currier, Time And Change In Judge-Made Law: Prospective Overruling, 51 Vir.L.Rev. 201, 247-248 (1965); C. Auerbach, L. Garrison, W. Hurst & S. Mermin, The Legal Process 174 (1961). Some of these commentators charged that the nonretroactivity approach has produced gross inequality of treatment for similarly situated persons then in the "pipeline” by excluding them from the benefits of a new rule of constitutional law. The "pipeline doctrine ” refers to those interests presently in litigation (i.e., the case before the court and cases pending before the trial tribunals or in the appellate litigation process) or capable of being litigated when the new rule is announced. For references to the pipeline doctrine see Michigan v. Payne, 412 U.S. 47, 60, 93 S.Ct. 1966, 1973, 36 L.Ed.2d 736 (1973) (Douglas, J., dissenting); Hawkins, Florida Constitutional Law: A Ten-Year Retrospective On The State Bill of Rights, 14 Nova L.Rev. 693, 750 (1990); Fallon, New Law, Non-Retroactivity, and Constitutional Remedies, 104 Har.L.Rev. 1731, 1815 (1991). For Oklahoma jurisprudence applying a new rule of law to cases in the pipeline see Amoco Production v. Corp. Com’n of Okl., OkI.App., 751 P.2d 203, 208 (1986); Schepp v. Hess, Okl., 770 P.2d 34, 39 (1989); Dow Jones & Co. v. State ex rel. Tax Com'n, Okl, 787 P.2d 843, 847 (1990). Beam is the ultimate refinement of the pipeline doctrine aimed at securing equality for all claims pending or those capable of being litigated when the new rule is announced.

45 .For state and federal decisions that have applied Beam’s implied retroactivity analysis in concluding that retroactive sweep should be given to a new rule of federal law in every case in which the Court’s opinion was silent on its backward or forward reach, see Cambridge State Bank v. James, 480 N.W.2d 647 (Minn.1992); Fongerv. Department of Treasury, 193 Mich.App. 71, 483 N.W.2d 920 (1992), leave to appeal denied, 440 Mich. 888, 487 N.W.2d 472 (1992); Sizemore v.

The pipeline doctrine, supra note 44, is not appropriate for application to cases where the new rule is announced on review of a collateral attack upon an earlier judgment. Oklahoma’s retrospectivity jurisprudence makes a distinction between "direct review” (direct appeal or direct attack) on the one hand and "collateral review” (collateral attack) on the other. See Harry R. Carlile Trust v. Cotton Petroleum, Okl., 732 P.2d 438, 447-448 nn. 46, 49 (1987), which gives purely prospective sweep to a new constitutional rule declared in a collateral attack upon a Corporation Commission spacing order. Among the reasons Cotton Petroleum advances for not applying the pipeline doctrine to collateral challenges are (1) society's interest in finality of decisions, (2) the need to conserve judicial time and expense, and (3) evidence and records in old cases may deteriorate, fade away, or vanish. Id. at 447 n. 46, 448 (citing support in federal jurisprudence). See in this connection, Mishkin, The Supreme Court 1964 Tern Foreword: The High Court, The Great Writ, And The Due Process Of Time And Law, 79 Har.L.Rev. 56, 77-79 (1965); Corr, Retroactivity: A Study In Supreme Court Doctrine "As Applied", 61 N.C.L.Rev. 745, 750-752 (1983); but cf.

Schwartz, Retroactivity, Reliability, and Due Process: A Reply to Professor Mishkin, 33 U.Chi. L.Rev. 719, 730-734 (1966); Cotton Petroleum, supra at 449-450 (Kauger, J., dissenting in part). The pipeline doctrine was fashioned for a new rule’s application in a direct appeal. This is evident from the writings of those who supported the pipeline in Hatper and Beam. I. HARPER; The Harper retroactivity rule applies "in all cases still open on direct review.” Harper, supra note 2, 509 U.S. at-, 113 S.Ct. at 2517. Justice Scalia’s concurring opinion notes that in Teague, supra note 35, the plurality "openly rejected settled precedent controlling the scope of retroactivity on collateral review.” In his view "abandonment of [the Court’s] prior collateral-review ret-roactivity rule was fully in accord with the doctrine of stare decisis.’’ (Harper, supra note 2, 509 U.S. at-, 113 S.Ct. at 2520 (Scalia, J., concurring)). II. BEAM: A six-justice majority concludes in Beam that litigants in the pipeline may on direct review receive the benefit of a new constitutional rule of civil law. (a) Justice Souter stresses that "retroactivity in civil cases must be limited by the need for finality...." He opines that " ‘fpjublic policy dictates that there be an end to litigation; that those who have contested an issue shall be bound by the result of that contest, and that matters once tried shall be considered forever settled as between tlte parties.' ” Beam, supra note 3, 501 U.S. at-, 111 S.Ct. at 2446-2447 (citations omitted) (emphasis added), (b) Justice Blackmun states that "failure to apply a newly declared constitutional rule to cases pending on direct review violates basic norms of constitutional adjudication.” Id., 501 U.S. at -, 111 S.Ct. at 2449 (Blackmun, J., concurring in judgment), (c) Justice White comments that the new rule "is to be applied to other litigants whose cases were not final at the time of the Bacchus decision.” Id., 501 U.S. at -, 111 S.Ct. at 2448 (White, J., concurring in judgment) (emphasis added). Application of the pipeline doctrine is appropriate in the instant case because the Taxpayers seek the benefit of a new rule on direct review of the Tax Commission’s denial of their refund claims. In Teague, supra note 35, 489 U.S. at 311, 109 S.Ct. at 1074, Justice O’Connor, writing for a plurality, states:

"[I]t has long been established that a final civil judgment entered under a given rule of law may withstand subsequent judicial change in that rule. In Chicot County Drainage District v. Baxter State Bank, 308 U.S. 371, 60 S.Ct. 317, 84 L.Ed. 329 (1940), the Court held that a judgment based on a jurisdictional statute later found to be unconstitutional could have res judicata effect. The Court based its decision in large part on finality concerns. ‘The actual existence of a statute, prior to such a determination [of unconstitutionality], is an operative fact and may have consequences which cannot justly be ignored. The past cannot always be erased by a new judicial declaration ... Questions of ... prior determinations deemed to have finality and acted upon accordingly ... demand examination.’ Id., 308 U.S. at 374, 60 S.Ct. at 318-319. Accord, Rookerv. Fidelity Trust Co., 263 U.S. 413, 415, 44 S.Ct. 149, 150, 68 L.Ed. 362 (1923) ('Unless and until ... reversed or modified’ on appeal, an erroneous constitutional decision is ‘an effective and conclusive adjudication'); Thompson v. Tol-mie, 2 Pet. 157, 169, 7 L.Ed. 381 (1829) (errors or mistakes of court with competent jurisdiction 'cannot he corrected or examined when brought up collaterally')." (Emphasis added.)

49 . Dow Jones, supra note 44 at 845; State ex rel. York v. Turpén, Okl., 681 P.2d 763, 767 (1984).

Art. 7, § 1, Okl. Const., confers on administrative agencies only that quantum of “judicial power” which is necessary to support their exercise of adjudicative authority in individual proceedings brought before them. The power assigned to boards and commissions is not coextensive with that which is vested in the courts. Dow Jones, supra note 44 at 845.

50 . In his post-Davis 1988 return Worrell claimed an exemption from state taxes on his federal retirement income. When the exemption was denied, Worrell filed a protest with the Commission and paid the proposed amount. He had voluntarily paid without protest state taxes on his civil service retirement income in his 1985, 1986 and 1987 returns and seeks a refund of his pre-Davis voluntary overpayments.

51 . Harper, supra note 2. See discussion of due process in Part V(E), infra.

52 . The terms of Art. 2, § 7, Okl. Const., are: "No person shall be deprived of life, liberty, or property, without due process of law.”

53 .The Income Tax Division’s stipulations before the Commission are:

"[T]he Division is prepared to stipulate for the record that the refund claims that are at issue in these proceedings are currently for the years 1981 through 1988, although I understand that counsel for Mr. and Mrs. Lankford will have an announcement as to some of those years.” [Record 5]

"We're also prepared to stipulate that only the Plaintiffs involved in these proceedings for the years in question were recipients of the retirement income benefits from the United States Government either as civil service or as military retirees.” [Record 5]

"We further stipulate that the claims for the years in question subject to, we expect an announcement as to the years 1981 through 1984 [the Lankfords withdrew their claims for the years 1981-1984, [Record 7-8], we'd stipulate that those claims were timely filed. We further stipulate that the claims were denied by the Income Tax Division and that the denials were all timely protested.” [Record 5-6] "I stand corrected. Further, the amounts claim[ed] as reflected, I believe, in the Court's file, we stipulate as to the dollar amount if the Taxpayers are entitled to a refund in this case, the subject that's at issue, but the amounts claimed, we stipulate as being correct with the exception of Mr. Worrell and the exception is only as to what may appear in the Court's file because it has been changed since the original filing. We have ... come to an agreement.... Mr Worrell's claim for when he filed is $790.00, for 1986 is $1869.00, for 1987 is $2165.00 and for 1988 is $2405.00 for a total of $7229.00. There is no contention between the Division and Taxpayers as to the correctness of the amounts if refunds are to be made.” [Record 6]

54 . Record at 392 (emphasis added).

55 . Record at 479 (emphasis added).

56 . The Commission's answer brief on appeal states that the question presented is whether Davis “is to be applied retroactively, so as to require refund or abatement of taxes paid or assessed for the tax years 1985 through 1988, or prospectively only from the date of that decision. ” Answer brief at 3.

57 . Admissions against a party's interest made in a brief may be used to supplement the appellate record. Hulsey v. Mid-America Preferred Ins. Co., Okl., 777 P.2d 932, 937 n. 17 (1989); Kwikset/Emhart v. Mayberry, Okl., 800 P.2d 239, 240 n. 1 (1990); Reeves v. Agee, Okl.; 769 P.2d 745, (1989); Womack v.

"If, upon any revision or adjustment ... any refund is found to be due any taxpayer, it shall be paid ... out of the "Income Tax Adjustment Fund”, created by Section 2352 of this title,

Except as provided in Section 2375(G) of this title, the amount of the refund shall not exceed the portion of the tax paid during the three (3) years immediately preceding the filing of the claim, or, if no claim was filed, then during the three (3) years immediately preceding the allowance of the refund;

The quoted language was not substantially changed by the 1985 and 1991 amendments.

65 . Neither party on appeal will be allowed to change the theory of the case from that on which it was presented to the trial court. Agricultural Insurance Company v. Kouba, Okl., 294 P.2d 583, 586 (1956). Parties are bound in the appellate court by the theories on which a case was tried below. Chrysler Corporation v. Walter E. Allen, Inc., Okl., 375 P.2d 878, 883 (1962); Griswold v. Public Service Co. of Oklahoma, 205 Okl. 412, 238 P.2d 322, 326 (1951).

66 . In a public-law controversy, this court is generally free to change the theory presented by the parties below and followed by the trial court. In the Matter of McNeely, Okl., 734 P.2d 1294, 1296 (1987); Burdick v. Independent School Dist., Okl., 702 P.2d 48, 54 (1985); Davis v. Davis, Okl., 708 P.2d 1102, 1104 n. 2 (1985); McCracken v.

67 . The words "ultra vires " mean "beyond the power”. State v. Benevolent Investment & Relief Ass’n, 107 Okl. 228, 232 P. 35, 38 (1925). "An act is said to be ultra vires when it is not within the scope of the powers ... to perform it under any circumstances or for any purpose.” Field v. City of Shawnee, 7 Okl. 73, 54 P. 318, 319 (1898). An ultra vires act is one which is beyond the powers conferred by law. BLACK’S LAW DICTIONARY at 1365 (5th Ed.1979), citing Charles v. Town of Jeanerette, Inc., 234 So.2d 794, 798 (La.App.1970).

68 . The terms of 68 O.S.1981 § 2375(G) provided in pertinent part:

" * * * If the amount of the net income for any year of the taxpayer under this law, and as returned to the United States Treasury Department, is changed or corrected by the Internal Revenue Service, such taxpayer, within one (1) year after final determination of the corrected net income, shall file an amended return reporting the corrected net income, or notify the Tax Commission by letter that the information is available, and the Tax Commission shall make assessment or refund based thereon...."

An effective and evenhanded mechanism for the state’s return "in hindsight” of unconstitutionally exacted revenue is mandated by federal due process. Harper, supra note 2, 509 U.S. at-, 113 S.Ct. at 2520. Its command will go unheeded if timely refund claims for voluntary pre-Davis overpayment are rejected out-of-hand as excluda-ble by our statutory framework of available remedies.

82 . Taxpayers sought interest on refunds. Because the Commission decided no refunds were due, it did not reach the interest claim.

83 .See supra note 64 for pertinent terms of 68 O.S.1981 § 2373. We do not, and need not, today reach for discussion Taxpayers' remedy for refund of tax paid more than three years before refund request.
