REVENUE-TECH

It changes Section 1-1 from "the the Property Tax Code" to "Property Tax Code" to fix a grammatical duplication. This procedural bill affects how the code is officially referenced but does not alter any tax laws, policies, or taxpayer obligations. It is purely a citation correction with no substantive policy impact.
