Ballot initiative mechanics in Maine

This page covers Maine's specific rules. For the general mechanics, see how ballot initiatives work. Maine allows direct initiative of state statutes and a people's veto of laws the legislature has passed, but not constitutional amendments by initiative.

Maine's process

A sponsor files a written, notarized application with the Secretary of State, co-signed by 5 other registered voters, along with the full text of the proposed law. The Secretary of State reviews and clears the petition to circulate within 15 business days.

The signature threshold is 10 percent of the total votes cast for governor in the most recent gubernatorial election. For 2026 that's 67,682 signatures, based on the 2022 governor's race. There is no geographic distribution requirement: signatures can come from any county or district in any proportion, which sets Maine apart from many other initiative states. Once cleared to circulate, proponents have up to 18 months to gather signatures, and any single signature more than a year old is invalid at filing.

Deadlines and numbers

Rules

Maine's process is comparatively accessible: no geographic distribution requirement, a modest opening threshold (just 5 co-signers to file), and an 18-month circulation window that gives volunteer-driven campaigns real time to build. The tradeoff is that the process only reaches statutes, not the state constitution, and each signature has a one-year shelf life, so campaigns that stall out can lose validated signatures before they finish.

The 50-day-after-session-convenes filing deadline is a hard cutoff for getting a measure in front of the First Regular Session. Missing it pushes a measure to the next available session or ballot. This dossier did not find an explicit filing fee for the citizen initiative application. The process appears to run on a notarized application and signatures rather than a monetary fee, but no official source states that affirmatively.
