An Initiative Petition may be filed at any time. It puts a measure on a ballot.
A Referendum Petition refers a legislative action to the voters.
A Referral is a resolution prepared by the governing body to place a question on the ballot for electors to decide. The referral is filed with the appropriate filing officer. The state governing body is the Legislature. Referrals are filed with the Oregon Secretary of State.
