Key legal question
Whether the gross gaming revenue had to be annualized when the tax period began during the year, despite the absence of an express rule in the former ordinance.
Extracted holding
Yes. The omission in the former ordinance was a genuine gap that had to be filled consistently with the Constitution; annualization was required for tax-rate determination.
Extracted reasoning
The Court held that annualization does not create a new taxable event or tax object, but only completes the rules on taxation in time. Because the tax is periodic and progressive, equal treatment and ability-to-pay require extrapolating revenue to twelve months for a shortened tax period.
