LANSING, Mich. (AP) — Lt. Gov. Brian Calley is starting a new effort to make Michigan’s Legislature part-time.

The Detroit News reports Calley’s Clean Michigan Committee announced Monday it submitted a new petition with revised language to the Secretary of State.

The new petition would generally require lawmakers to finish the regular legislative session by April 15 each year. The previous version sought to limit the regular session to 90 consecutive days.

In a statement, Calley says his group has learned about legal strategy opponents plan to use try to defeat the effort. The Portland Republican says the group decided “to take every step to ensure voters have their say on this important reform.”

The Clean Michigan Committee had struggled to get the Board of State Canvassers to approve the original petition language.
