Desoto Gathering Co. v. Hill, 541 S.W.3d 415

DeSoto Gathering Co. owned personal property assessed for 2012 ad valorem taxes in Faulkner County and challenged the assessment before the county BOE, county court, and then Faulkner County Circuit Court (a valuation appeal).
While litigating valuation, DeSoto discovered some property was located in Conway County and some intangible property was exempt; it paid 2012 taxes under an escrow order but later filed a county-court refund claim under Ark. Code § 26-35-901 for taxes allegedly erroneously assessed and paid.
Hill (Faulkner County Assessor and related county officials) moved to dismiss the refund suit under Ark. R. Civ. P. 12(b)(8) as duplicative of the pending valuation appeal, and alternatively argued res judicata because refund claims could have been raised in the valuation case.
The circuit court granted dismissal, finding (1) Rule 12(b)(8) required dismissal because the valuation appeal was still on appeal, and (2) res judicata barred the refund claim because both suits arose from the same 2012 assessment and the refund claims could have been raised in the valuation action.
On appeal the Arkansas Supreme Court reversed: it held Rule 12(b)(8) did not apply because the valuation and refund actions arise under different statutory schemes and address different issues/remedies, and res judicata did not apply because the prior valuation case had been dismissed for lack of subject-matter jurisdiction (so there was no valid judgment by a court of proper jurisdiction).

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether Rule 12(b)(8) (pendency of another action arising from same transaction or occurrence) required dismissal of refund suit	DeSoto: refund claim is a distinct statutory cause (Ark. Code § 26-35-901) addressing erroneous assessments and refunds, separate from valuation appeals under §§ 26-27-317–318	Hill: both suits arise from the same 2012 assessment; Rule 12(b)(8) prevents multiplicity of suits and requires dismissal	Court: Rule 12(b)(8) did not apply — valuation and refund procedures/statutory objects differ, so dismissal under Rule 12(b)(8) was erroneous
Whether res judicata (claim preclusion) barred the refund suit	DeSoto: prior valuation appeal was dismissed for lack of subject-matter jurisdiction, so no valid judgment; claim preclusion cannot attach	Hill: refund claims could have been raised in the valuation appeal; prior litigation arises from same transaction so preclusion should apply	Court: res judicata did not bar the refund claim because the earlier case was dismissed for lack of subject-matter jurisdiction, so one element of claim preclusion (final judgment by court of proper jurisdiction) is missing
