Musselshell County v. Yellowstone County
Annotate this CaseAn underground mine with surface facilities located in Musselshell County (Musselshell) extended underground into Yellowstone County (Yellowstone) and produced coal mined from both Musselshell and Yellowstone. Based upon a report of the counties from which the coal was mined, the Department of Revenue allocated approximately two-thirds of the mine's taxable coal gross proceeds to Musselshell, for a tax of $328,617, and the remainder to Yellowstone, for a tax of $126,909. Musselshell sued Yellowstone and the Department seeking a declaratory judgment that the Department wrongfully allocated a portion of the tax to Yellowstone. The district court upheld the Department's apportionment of the tax between the two counties, holding that Montana law contemplates taxation of the gross proceeds of coal in the county where the coal is mined and that the Department was not required to adopt administrative rules prior to apportioning the tax. The Supreme Court affirmed, holding that the Department correctly apportioned the coal gross proceeds tax from the mine between Musselshell and Yellowstone and was not required by law to create an administrative rule before making that apportionment.
