923 N.W.2d 17
Minn.2019Background
- Enbridge Energy, LP (EELP) challenged the Commissioner of Revenue's valuation of its interstate petroleum pipeline system for 2013–2015; tax-court proceedings were consolidated and stayed pending Minnesota Energy Resources Corp. v. Commissioner (MERC).
- After MERC, the tax court held a trial and concluded the Commissioner had overvalued the system, set new unit values using the income approach, and refused to allocate unit value between Minnesota and other states under Minnesota Rule 8100.
- The tax court rejected the Commissioner’s cost-approach and the Rule 8100 allocation formula, reasoning the Rule applied only to the Commissioner and might produce inaccurate valuations compared to de novo proceedings before the tax court.
- The Commissioner petitioned for discretionary review, arguing Rule 8100 (an administrative rule prescribing valuation and allocation steps, and default weightings favoring cost and income approaches) is binding on the tax court.
- The Supreme Court had previously held in MERC that Rule 8100 is binding on the tax court; the central question here was whether the tax court erred in concluding otherwise in EELP’s case.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the tax court is bound by Minn. R. 8100 when valuing pipeline unit value | Rule 8100 is binding but its discretionary provisions let the court reject the cost approach when warranted | Rule 8100 binds the tax court; mere disagreement with the rule does not permit departure | The tax court is bound by Rule 8100; it erred to conclude otherwise |
| Whether the tax court may disregard Rule 8100 because it is worded to direct the Commissioner | Rule text targets the Commissioner, so the tax court is not directly governed by it | Rule applies “by extension” to the tax court when performing valuation duties | Rule 8100 applies to the tax court by extension; wording aimed at Commissioner does not exempt the court |
| Whether the tax court may depart from Rule 8100 because it believes the rule yields inaccurate valuations | Tax court’s de novo review function permits rejection of administrative formulae that produce inaccurate results | MERC and precedent disallow departure based on disagreement; rules bind courts unless they conflict with statute | Disagreement about accuracy is not a valid basis to ignore the rule; court must follow rule unless it conflicts with statute |
| Allocation of system unit value when the court uses a different valuation approach than Rule 8100 prescribes | If the court uses income approach, the Rule’s cost-based allocation becomes unworkable | The tax court must still follow Rule 8100 and explain its reasoning if it departs in application | The court must apply Rule 8100 (and fully explain any deviations grounded in statute or rule-based reasoning) |
