Assembly Bill 1163 aims to regulate sales practices at publicly funded stadiums in Wisconsin by prohibiting stadium owners, operators, or concessionaires from selling food or beverages at prices exceeding their cost plus a 20 percent markup. The bill defines a stadium as a multipurpose facility with a capacity of at least 3,000 persons that receives public financial support, excluding facilities owned or leased by primary or secondary schools. Violations of this provision would be considered unfair trade practices and enforceable by the Department of Agriculture, Trade and Consumer Protection.

The bill introduces new statutory sections, specifically 100.20 (1p) and 100.306, which outline the definitions and prohibitions related to unfair sales practices at these stadiums. The definitions clarify terms such as "concessionaire" and "public financial support," while the prohibition section explicitly states the pricing limitations for food and beverages sold within the stadiums. This legislation seeks to ensure fair pricing for consumers attending events at publicly funded venues.
