Chevron U.S.A. Inc. v. Arizona Department of Revenue
363 P.3d 136
Ariz. Ct. App.2015Background
- Chevron sold industrial oils and greases to Freeport-McMoRan for use in mining and metallurgical machinery; Chevron paid transaction privilege tax and sought a refund of $324,233.79 for taxes paid from 2002–2006.
- Chevron claimed the sales were exempt under A.R.S. § 42-5061(B)(1), (2), (18) (machinery/equipment used in metallurgical/mining operations and pollution control).
- The Arizona Department of Revenue refunded a small portion (hydraulic oils and transmission fluids) but denied refunds for engine oil, gear oil, grease, and open-gear lube, treating them as taxable "expendable materials."
- The tax court granted summary judgment for the Department; Chevron appealed to the Arizona Court of Appeals.
- The Court of Appeals reviewed statutory interpretation de novo, applied the 1999 amendment that exempts items "regardless of the cost or useful life" if they otherwise qualify, and examined whether oils/greases function as machinery/equipment under the integrated-system test.
- The court concluded the products are integral, necessary components of Freeport’s equipment (reducing friction, dissipating heat, suspending contaminants, enabling operation) and therefore exempt; it reversed and remanded with direction to enter judgment for Chevron and awarded appellate attorney fees.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether oils/greases sold to mining operator are exempt under A.R.S. § 42-5061(B)(1),(2),(18) | Chevron: oils/greases are "equipment" used directly in mining/metallurgical operations and thus exempt | DOR: they are expendable materials used up quickly and not the functional equivalent of machinery/equipment, so taxable | Held: Exempt — oils/greases function as integral equipment under the integrated-system test |
| Whether expendability/useful life bars exemption | Chevron: 1999 amendment removed useful-life/expendability as disqualifier if item otherwise qualifies | DOR: expendable materials remain taxable under § 42-5061(C)(1) | Held: 1999 amendment means expendability is not dispositive; must ask whether item qualifies under subsection B |
| Proper interpretive test for machinery/equipment exemption | Chevron: adopt Capitol Castings’ flexible, functional "integrated, synchronized system" test | DOR: insists on a narrower equivalence to traditional machinery | Held: Apply Capitol Castings — focus on item’s function and role, not material or physical contact with raw materials |
| Whether summary judgment can be decided as pure law on undisputed facts | Chevron: yes — record facts undisputed; legal issue controls | DOR: opposed | Held: Yes — appellate court may reverse and enter judgment when appropriate |
