House Bill No. 591, introduced by Representative Lyons, aims to establish regulations concerning online marketplaces by enacting R.S. 51:3267. The bill defines key terms such as "local governing authority," which refers to the legislative bodies of cities, municipalities, parishes, or other political subdivisions in Louisiana, and "online marketplace," which encompasses entities that facilitate transactions through various digital platforms. Notably, the bill clarifies that online marketplaces do not include local or state governmental entities or vendors.

The legislation explicitly prohibits local governing authorities from regulating the operation of online marketplaces. Additionally, it restricts these authorities from requiring online marketplaces to disclose personally identifiable information of users unless there is an administrative subpoena or court order. This bill seeks to protect the operational integrity of online marketplaces and ensure user privacy by limiting local governmental oversight.
