Definition modification of lobbyist and metropolitan government unit

SF 2562 modifies Minnesota's definitions of "lobbyist" and "metropolitan governmental unit" in campaign finance laws. It adds a new definition for "expert witness" as someone providing testimony based on professional expertise, and excludes paid expert witnesses from being classified as lobbyists when testifying at public meetings or making testimony publicly available. The bill also updates the lobbyist definition to clarify that certain government employees, political subdivision staff, and collective bargaining representatives are not considered lobbyists under specific conditions. These changes primarily affect individuals and organizations engaging in lobbying activities, requiring clearer reporting for those who do qualify as lobbyists under the revised rules.
