432 P.3d 976
Idaho2018Background
- The City of Hayden imposed a one-time sewer capitalization ("2007 Cap") fee that rose from $774 to $2,280 per Equivalent Residence (ER) in June 2007; plaintiffs (NIBCA and class members) sued claiming the fee was an impermissible tax.
- On initial summary judgment the district court upheld the fee; this Court (NIBCA I) vacated and remanded because the record lacked evidence that the fee was based on the value of the portion of the existing system the new user would utilize.
- On remand the City commissioned an FCS study (2015) aiming to show the 2007 fee complied with Idaho law (Loomis methodology); the district court refused to consider that evidence and granted summary judgment to NIBCA.
- The district court then entered judgment requiring refunds (difference between $2,280 and $774) plus interest, costs, and attorney fees to plaintiffs; the City appealed the exclusion of its evidence and other rulings.
- The Idaho Supreme Court vacated the district court judgment and attorney-fee award, holding the trial court erred in refusing to consider the City’s evidence and remanded for development of the record on whether the 2007 Cap Fee complied with Idaho law.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether the 2007 Cap Fee was an impermissible tax vs. a lawful fee | Fee was really a tax because it was based on system expansion costs, not value of existing capacity used by new users | Fee is lawful if it is reasonably connected to costs of providing service and was placed in a sewer fund; FCS study shows fee was justified | Remanded: district court erred by excluding City evidence; factual development required to determine whether fee complied with Loomis/Viking criteria |
| Whether City may introduce post-hoc evidence (FCS study) to justify 2007 fee | Post-hoc justification is impermissible and offends fairness; the fee was unlawful when enacted | Post-hoc evidence is admissible to develop record and show fee was reasonable and non-revenue-raising; timing does not bar consideration | City may present evidence on remand; timing alone does not preclude showing fee complied with law |
| Ripeness of federal takings claim (Williamson County second prong) | NIBCA: facial takings/declaratory claim is ripe; state notice or Regulatory Takings Act not required for federal claim | City: federal claim unripe because plaintiffs didn’t exhaust state remedies/notice requirements | Affirmed: facial takings claim allowed; ITCA notice does not bar federal claim; Regulatory Takings Act was limited to real property at time, so plaintiffs not required to use it |
| Applicability of equitable defenses (unjust enrichment/quantum meruit/unclean hands) | NIBCA: City’s unlawful enactment and failure to follow required methodology bars equitable relief to City | City: plaintiffs received benefit from system; equitable defenses should preclude full refund | Vacated: district court abused discretion in rejecting City defenses without hearing City evidence; defenses must be reconsidered on remand |
