Justia Montana Supreme Court Opinion Summaries

The Montana Department of Revenue ("Department") appealed a judgment reversing the State Tax Appeal Board's ("STAB") conclusion that the Department had applied a "commonly accepted" method to assess the value of PacificCorp's Montana properties. At issue was whether substantial evidence demonstrated common acceptance of the Department's direct capitalization method that derived earnings-to-price ratios from an industry-wide analysis. Also at issue was whether substantial evidence supported STAB's conclusion that additional obsolescence did not exist to warrant consideration of further adjustments to PacifiCorp's taxable value. The court held that substantial evidence supported the Department's use of earnings-to-price ratios in its direct capitalization approach; that additional depreciation deductions were not warranted; and that the Department did not overvalue PacifiCorp's property. The court also held that MCA 15-8-111(2)(b) did not require the Department to conduct a separate, additional obsolescence study when no evidence suggested that obsolescence existed that has not been accounted for in the taxpayer's Federal Energy Regulatory Commission ("FERC") Form 1 filing. The court further held that STAB correctly determined that the actual $9.4 billion sales price of PacifiCorp verified that the Department's $7.1 billion assessment had not overvalued PacifiCorp's properties.
