To establish that signatures on a petition to amend the constitution must be collected within the 180 days before the measure is submitted. Under current law there is a presumption that an older signature is void, but this can be rebutted in an administrative procedure. The bill would remove that "rebuttable presumption" language, making older signatures void without qualification. The House concurred with the Senate on giving the bill immediate effect, which would mean marijuana legalization and anti-fracking petition drives underway in the spring of 2016 would be impacted.
