Can landowners testify about highest and best use without expert qualification? City of Hildale v. Cooke Explained

In eminent domain proceedings, determining just compensation often hinges on establishing the highest and best use of condemned property. The Utah Supreme Court’s decision in City of Hildale v. Cooke provides crucial guidance on who may testify about this critical valuation element.

Background and Facts

The City of Hildale condemned easements on properties owned by Gherri Cooke and Barbara Hall for electrical transmission lines. At trial to determine damages, the landowners testified that the highest and best use of their properties was residential subdivision development. They described extensive preparations including drilling wells, installing utilities, conducting soil tests, and obtaining permits. Based on this testimony, they claimed substantial severance damages — $65,000 for Cooke and $15,000 for Hall. Notably, all expert appraisers in the case, including the landowners’ own expert, testified that the highest and best use was investment holding, not residential development.

Key Legal Issues

The central issue was whether landowners may testify about the highest and best use of their property without being qualified as experts. The court also addressed whether such improper testimony warranted reversal and how prejudgment interest should be calculated in condemnation cases.

Court’s Analysis and Holding

The Utah Supreme Court held that “highest and best use” is a term of art in eminent domain proceedings requiring expert testimony. Citing Utah Dep’t of Transportation v. Jones, the court emphasized that “ownership of the land alone would not qualify [a landowner] to give such an opinion.” While landowners may testify about specific improvement activities and their plans for the property, they cannot offer conclusions about highest and best use without proper expert qualification. The court found this error prejudicial because the landowners’ severance damage estimates were entirely premised on their inadmissible highest and best use opinions.

Practice Implications

This decision reinforces the importance of proper expert witness foundation in condemnation proceedings. Practitioners should move to exclude landowner testimony on highest and best use unless the witness has been qualified as an expert. The ruling also demonstrates how evidentiary errors can be prejudicial when they form the basis for damage calculations, potentially warranting reversal even in cases with substantial evidence supporting other aspects of the verdict.
