The Michigan Lobby Registration Act, Public Act 472 of 1978, was enacted in order to provide public disclosure of the lobbying of state level public officials.  Public officials are state level elected or appointed public officials who are designated as "lobbyable" under the Act.   The Lobby Act does not function as a licensing requirement for lobbyist or agents.  The Lobby Act does require persons, who make expenditures or receive compensation or reimbursement for lobbying activities in excess of thresholds specified under the Act, to register and report as lobbyists or lobbyist agents with the Michigan Department of State, Bureau of Elections.  The thresholds are effective each calendar year and are adjusted annually to reflect changes in the Detroit Consumer Price Index.
