SB 567 proposes restrictions on the use of public school buildings as polling places during elections. It amends the Texas Election Code to state that polling places cannot be located in buildings owned or controlled by a school district or open-enrollment charter school unless specific exceptions apply. These exceptions include instances where the building is not situated on or adjacent to a school campus, or if the building is in a county with a population of 50,000 or less and there are no reasonable alternative polling places available.
