A Referendum Petition can only be filed in response to legislative action in the last session. If a bill had an “Emergency Clause” it cannot be reversed by the Referendum process. There were three filed: 301, 302, and 303 but “09/24/2021 Signatures were not turned in for verification by the deadline.” Therefore, there are no Referendums filed for the 2022 ballot.
