1. Every bill, act, or legislative proposal introduced or voted upon must embrace only one single subject, which shall be clearly expressed in its title.
2. All provisions within a bill must have a direct, logical, and natural connection to the primary subject. Provisions that are substantive in nature cannot be grouped together solely under the guise of "Budgetary Measures" or "Miscellaneous Provisions."
3. Any provision or section of an act that is not germane to the single subject expressed in the title is void ab initio. If the non-germane provisions are inseparable from the whole, the entire act is void.
