In 2016, supporters had hoped that the Michigan Marijuana Legalization and Regulation Initiative (Marijuana Legalization Initiative) would be on the November 8 ballot. This did not happen, in large part because of a law that took effect in June of that year, SB 776, that invalidated any signature on a petition seeking to amend the constitution when it was made more than 180 days before the petition was filed with the Secretary of State’s office.
Proponents of marijuana legalization had joined forces with advocates of a fracking ban ballot initiative to make the signature validation process easier, but SB 776 took hold instead. Prior to that bill’s passage, petitioners for Michigan’s Marijuana Legalization Initiative had four years to collect signatures, but those that were more than 180 days old were assumed to be invalid unless petitioners proved validity. Now, all signatures must be collected in that 180 day window.
