The Oregon Petition to Obtain is an online petition for individuals or organizations to request changes in Oregon law or policy. This petition can be used to ask state lawmakers to consider a bill, or to ask for changes to exist laws or regulations. There are two types of Oregon Petition to Obtain: Initiated Measure Petition and Referendum Petition. An Initiated Measure Petition is used to propose a new law or amendment to an existing law, and can be signed by registered Oregon voters. A Referendum Petition is used to repeal an existing law, and must be signed by a certain number of registered Oregon voters. Both types of petitions require that the signatures be collected within a certain period of time and then submitted to the Secretary of State for approval and official filing.
