This is an eminent domain dispute involving the construction of a high-speed train line. A defendant rail company sought to acquire portions of private residential property from property owners along the proposed line route the line. State law required that the rail company provide just compensation to these property owners for the interest that it acquired, for severance damages or loss in property value suffered as a result of the partial taking, and of any adverse effects of the public project that necessitated the taking. It was alleged that the rail company and its appraisers failed to value the severance damages and have failed to mention the terms at all in the appraisals. An expert in real estate appraisal was sought to testify as to the fair market value of the properties subjected to the partial eminent domain for construction of the line.
