Upon the filing of any bill proposing to regulate an occupation not regulated by the State, the subcommittee of the standing committee of the House of Representatives or the Senate to which the bill has been referred may request that the commission conduct the public hearing or that the commission assist the subcommittee in conducting the public hearing. Upon the request of the subcommittee, the commission may hold hearings for the purpose of determining whether or not occupations not regulated by the State should be regulated.
