Century Aluminum of Ky., GP v. Department of Revenue
Annotate this Case
The Supreme Court reversed the opinion of the court of appeals affirming the decision of the circuit court concluding that with Century Aluminum of Kentucky, GP's interpretation of the statutes which categorize tangible personal property as either tax-exempt "supplies" or taxable "repair, replacement, or spare parts" was incorrect, holding that that the Kentucky Claims Commission's final order was supported by substantial evidence.
In the proceedings below, the Commission agreed with Century's interpretation of the relevant statutes and rejected the interpretation of the Department of Revenue. The circuit court and court of appeals reversed, agreeing with the Department's interpretation. The Supreme Court reversed, holding (1) a tax-exempt "supply" is consumed within the manufacturing process and has a useful life of less than one year; (2) a taxable "repair, replacement, or spare part" does not necessarily have a known, limited useful life; and (3) the Commission's final order in this case was supported by substantial evidence in the record.
