The Maine Ethics Commission has drafted a proposal to mandate lobbying reports from any group spending over $2,000 in a month on grassroots activism, including television or digital advertising, aimed at pending legislation.

The current threshold to trigger a report is $15,000, and even then only if the group first employs a traditional lobbyist.

The commission’s proposal is partly a response to the environmental organization Stop the Corridor, which ran advertisements last year opposing a proposed transmission line while lawmakers were considering bills pertaining to the project.

Ethics Commission proposals go to the state Legislature, which decides if it will craft them into legislation.
