291 P.3d 442
Idaho2012Background
- PacifiCorp challenged Idaho tax valuation of its Idaho operating property for 2008, arguing Commission’s appraisal was erroneous.
- District court conducted a de novo review under I.C. § 63-409 and favored PacifiCorp’s Tegarden appraisal over the Commission’s methods.
- The Commission’s appraisal relied on Rudd’s cost approach with external obsolescence adjustments; PacifiCorp presented Tegarden’s MAI valuation with different methodologies.
- Idaho law permits market value valuation using cost, income, and/or comparable sales approaches; unit method applicable to utilities; obsolescence can be considered in the cost approach.
- Trial court weighed credibility of experts; found Tegarden more reliable, adopting his value as the record’s best estimate as of January 1, 2008.
- The court ultimately affirmed the district court’s judgment; costs awarded to PacifiCorp; attorney’s fees not requested.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| whether Tegarden’s external obsolescence deduction was legally permissible | PacifiCorp argues external obsolescence deductible via cost approach | Commission argues depreciation in FERC Form accounts for obsolescence; Tegarden’s deduction duplicative or unsupportable | Not clearly erroneous to allow Tegarden |
| whether the district court properly weighed expert testimony | PacifiCorp contends Tegarden more credible than Commission experts | Commission contends Tegarden’s methods are unreliable and subjective | District court’s credibility determinations upheld |
| whether the Commission erred by not using comparable sales or stock-and-debt approaches | PacifiCorp contends those approaches were appropriate but limited utility here | Commission argues those approaches were applicable but not persuasive for PacifiCorp | Not clearly erroneous to rely on Tegarden’s cost/income reconciliation |
| whether the weights assigned to cost and income approaches were proper | PacifiCorp argues different judgments; court should defer to appraiser reconciliation | Commission argues district court’s weighting is the standard | Weights within appraiser judgment; not clearly erroneous to adopt Tegarden’s weights |
| whether the district court properly concluded the Commission’s valuation was erroneous by preponderance | PacifiCorp asserts preponderance standard satisfied by Tegarden's value | Commission contends evidence insufficient or wrongly weighed | District court’s judgment affirmed; PacifiCorp entitled to relief by preponderance |
