430 P.3d 295
Wyo.2018Background
- Solvay Chemicals mined trona in Sweetwater County and sold soda ash mostly in bulk; a small portion was sold bagged, which incurred additional bagging costs.
- For tax years 2010–2012, DOR/DOA audited Solvay and calculated a smaller bagging-cost deduction than Solvay reported, producing an additional assessment; Solvay appealed the DOR’s final determination to the Wyoming Board of Equalization.
- Both parties’ pre-hearing filings, hearing, and post-hearing filings framed the dispute as the correct valuation/calculation of the bagging-cost deduction under Wyo. Stat. § 39-14-303(b).
- Months after the hearing the Board requested supplemental briefing on statutory construction: whether § 39-14-303(b) provides a single valuation method (industry factor) or multiple methods (including a separate processing/bagging deduction under (b)(iv)).
- The Board concluded that no separate bagging deduction is available and remanded for reassessment accordingly; Solvay challenged the Board’s authority to decide that statutory question because it had not been litigated below.
- The Wyoming Supreme Court reversed the Board, holding the Board exceeded its adjudicatory authority by deciding an issue not presented in the contested-case proceeding and remanded for the Board to adjudicate the dispute before it (i.e., the calculation of the bagging deduction).
Issues
| Issue | Plaintiff's Argument (Solvay) | Defendant's Argument (DOR/Board) | Held |
|---|---|---|---|
| Whether the Board acted without required procedure by deciding an issue not contested below | Solvay argued the Board should decide only the contested valuation (calculation) and that the separate statutory-interpretation issue was not presented | DOR/Board argued the Board could and should resolve the statutory construction question (whether (b)(ii) subsumes bagging costs) even if not initially litigated | Held: Board exceeded its authority by deciding a statutory question not before it in the contested-case; reversal and remand to decide the valuation dispute presented |
| Whether § 39-11-102.1(c)(iv) permits the Board to resolve statutory construction questions in adjudicatory appeals | Solvay maintained Board must adjudicate the valuation dispute and not supplant DOR's valuation power; Solvay objected to the late statutory issue | DOR/Board contended the Board may decide statutory construction questions under (c)(iv) even in adjudicatory proceedings | Held: Majority interpreted (c)(iv) as tied to the Board’s regulatory/equalization function and limited its use in adjudication; thus Board could not invoke (c)(iv) to decide an issue not applied for by an adversely affected party |
| Whether the Board’s action usurped DOR valuation authority | Solvay argued Board must either approve DOR’s valuation or remand; Board cannot arrive at its own valuation method | DOR/Board argued correcting statutory misinterpretation was within Board powers | Held: Board improperly invaded DOR’s statutory valuation role by reaching a new statutory conclusion outside the contested issue |
| Standard of review and presumptions applicable to DOR valuations | Solvay challenged DOR’s calculation; parties acknowledged statutory language was unambiguous | DOR invoked statutory interpretation to justify its new position that industry factor covers bagging | Held: Court reaffirmed presumption that DOR valuations are valid unless overturned in the contested hearing on the issues raised; Board must evaluate evidence and burdens on issues actually before it |
