Potlatch Corp. v. Idaho State Tax Commission

JOHNSON, Justice.

This is a use tax case involving the application of the “production exemption” contained in I.C. § 63-3622(d) [now I.C. § 63-3622D] (the production exemption). It is a companion case to Idaho State Tax Comm’n v. Haener, Dkt. No. 17729 (Idaho Dec. 11, 1990).

The exemption of several of the items that were originally at issue in this case was resolved in Haener. We apply Haener in a modified prospective fashion. We hold that the remainder of the items that are at issue here are not exempt from the use tax.
