Appellant Ashland Oil, Inc., a Kentucky corporation, is an integrated oil company that maintains business locations worldwide, including in West Virginia. During the years at issue here, West Virginia imposed a gross receipts tax on persons selling tangible property at wholesale. W. Va. Code § ll-13-2c (1983). Local manufacturers were exempt from the tax. §11-13-2. The West Virginia Tax Department conducted a detailed audit of Ashland’s tax returns for fiscal years ending September 1975 and 1976 and assessed a
*917
deficiency in tax payments of $181,313.22 for wholesale sales with West Virginia destinations. Ashland filed a timely petition for reassessment, primarily contending that the tax was unconstitutional as applied because there was an insufficient connection between its in-state activities and the transactions sought to be taxed. Juris. Statement 38a. After the State Tax Commissioner rejected Ashland’s petition, Ashland appealed to the Circuit Court of Kanawha County. While the appeal was pending, this Court decided
Armco Inc.
v.
Hardesty,
The West Virginia Supreme Court of Appeals reversed, holding that
Armco
did not apply retroactively, and remanded for further proceedings. Relying on its state-law criteria for retroactivity, see
Bradley
v.
Appalachian Power Co.,
*918
In its appeal to this Court, Ashland contends, among other claims, that the State Supreme Court of Appeals erred in determining that
Armco
applied prospectively only. Because “[t]he determination whether a constitutional decision of this Court is retroactive ... is a matter of federal law,”
American Trucking Assns., Inc.
v.
Smith,
Applying the view of retroactivity delineated by either the dissent or the plurality in
American Trucking Assns.,
we must reverse the state court’s decision. Under the reasoning of the dissent in
American Trucking Assns., Armco
applies retroactively to the taxes assessed against Ashland because constitutional decisions apply retroactively to all cases on direct review.
American Trucking Assns., Inc.
v.
Smith, supra,
at 212 (Stevens, J., dissenting). Under the approach of the plurality in
American Trucking Assns.,
the same result obtains, because
Armco
fails to satisfy the first prong of the plurality’s test for determining nonretroactivity. See
Chevron Oil Co.
v.
Huson,
The first prong of the
Chevron Oil
test requires that “the decision to be applied nonretroactively must establish a new principle of law, either by overruling clear past precedent on which litigants may have relied, or by deciding an issue of first impression whose resolution was not clearly foreshadowed.”
The Court next considered the argument that the State’s wholesale tax exemption did not discriminate against out-of-state taxpayers because it served as compensation for the imposition of a heavy manufacturing tax on in-state taxpayers. In
Maryland
v.
Louisiana,
Finally, the Court rejected the argument that Armco should be required to prove the tax had actual discriminatory impact. Instead, the Court asserted that the “internal consistency” test, enunciated in
Container Corp. of America
v.
Franchise Tax Bd.,
Armco
unquestionably contributed to the development of our dormant Commerce Clause jurisprudence. See,
e. g.,
Judson & Duffy, An Opportunity Missed:
Armco, Inc.
v.
*920
Hardesty,
A Retreat from Economic Reality in Analysis of State Taxes, 87 W. Va. L. Rev. 723, 740-743 (1985) (suggesting that
Armco’s
invalidation of a facially discriminatory tax statute signaled a retreat from the economically realistic approach adopted by
Complete Auto Transit, Inc.
v.
Brady,
*921 Because Armco did not overrule clear past precedent nor decide a wholly new issue of first impression, it does not meet the first prong of the Chevron Oil test. Armco thus applies retroactively under either the rule advocated by the plurality or the rule advocated by the dissent in American Trucking Assns., Inc. v. Smith. Accordingly, the State Supreme Court of Appeals erred in declining to apply Armco retroactively to determine the constitutionality of the State’s imposition of taxes on Ashland for the years at issue. The motion of the Committee on State Taxation of the Council of State Chambers of Commerce for leave to file a brief as ami-cus curiae is granted. We reverse the judgment of the State Circuit Court and remand the case for further proceedings not inconsistent with this opinion.
It is so ordered.
