943 N.W.2d 493
S.D.2020Background
- Patrick and Rose Mary Trask own an 11,091-acre ranch in Meade County assessed under South Dakota’s productivity-based agricultural valuation for 2016.
- County Director of Equalization Kirk Chaffee used Department of Revenue county income values tied to soil maps, then applied standardized discretionary adjustments (a 41% "crop adjustment" and a 20% "soil adjustment") to reflect parcel-specific conditions.
- Initial per-acre assessment was $539; Chaffee’s adjustments lowered it to $519/acre; the Board of Equalization further reduced it to $512/acre.
- The Trasks appealed to circuit court arguing (1) statutory noncompliance—certain data (AUMs, climate) and actual land use were ignored and (2) the assessment violated constitutional uniformity and actual-value limits.
- The circuit court upheld the assessment; the South Dakota Supreme Court affirmed, finding the Department’s productivity model and the director’s adjustments consistent with statutory authority and constitutional requirements.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether county complied with statutory scheme for valuing agricultural land under SDCL ch.10-6-33.28–33.33 | Trask: Director ignored statutorily listed data sources (animal units, climate) and relied on soil ratings to inflate productivity. | Appellees: Legislature centralized productivity data collection to the Department; director properly used that data and statute-authorized adjustments. | Court: No error — Department data and soil-match method govern; SDCL 10-6-33.2 does not displace the productivity statutes. |
| Whether valuation improperly used "potential" rather than actual use/production | Trask: Valuation based on unrealistic "potential" yields, overstating value for poor-performing areas. | Appellees: Productivity model looks to capacity, not current management; director’s discretionary adjustments address practical limitations. | Court: Held proper — statute measures capacity; adjustments mitigated overvaluation. |
| Whether director erred by not reclassifying soil categories (cropland vs noncropland) | Trask: Director could/should have recategorized certain acres as noncropland given poor actual performance. | Appellees: Soil classification follows USDA/NRCS soil surveys; director cannot arbitrarily change soil types but may adjust values. | Court: Held no reversible error — soil types are survey-based; substantial compliance suffices and adjustments were applied. |
| Whether assessment violated constitutional uniformity and actual-value caps | Trask: Assessment lacked uniformity (adjacent school land taxed as noncropland) and exceeded actual value given no production increase. | Appellees: Adjustments were applied uniformly using a handbook; assessed value below county market averages and within constitutional bounds. | Court: Held constitutional — Trasks failed to show nonuniform or excessive valuation; circuit court findings not clearly erroneous. |
