ANNOTATION
Section establishes a tax with two components: A base rate of 36 cents per ton of coal and the non-discretionary adjustment factor that is based upon changes in the index of producers' prices. Huber v. Colo. Mining Ass'n, 264 P.3d 884 (Colo. 2011).
Prior voter approval is not required for the tax rate increase on the severance of coal that is caused by the department of revenue applying the adjustment factor in subsection (5). The voter-approval requirement for a tax rate increase only applies to an increase enacted after the constitutional requirement, but the adjustment factor was enacted prior to it. Accordingly, the rate change is a nondiscretionary, ministerial function of the department and not a tax rate increase. Huber v. Colo. Mining Ass'n, 264 P.3d 884 (Colo. 2011).
