Salt Lake County v. Utah State Tax Commission

Summary

The Utah Supreme Court considers a challenge by Salt Lake County to the Utah State Tax Commission’s valuation of aircraft operating property for taxation. The opinion addresses the statutory requirements governing aircraft valuation, including the use of appraisal methods and fair-market-value principles.

Holdings

1. The Aircraft Valuation Law governed the assessment and required the Commission to apply the statutory valuation methodology to Delta's aircraft.
2. The County failed to establish that the assessment produced by the statutory methodology was constitutionally deficient or did not reasonably reflect fair market value.
3. The Commission was not required to use an alternative valuation method because the County did not satisfy the statutory conditions for invoking one.

Questions Presented

1. Whether Utah's Aircraft Valuation Law requires the Tax Commission to use its prescribed valuation methodology when assessing Delta Air Lines' aircraft.
2. Whether the statutory methodology produced an assessment below fair market value in violation of the Utah Constitution.
3. Whether the County established the statutory conditions necessary to require or permit use of an alternative valuation method.

Disposition

affirmed
