• The submission of a measure passed by the legislature to a vote of the people. In Oregon, either the legislature or citizens, by petition, may cause a measure passed by the legislature to be placed on the ballot for a vote. In the case of a legislative referral, both houses of the Legislature must vote to refer the measure. Such referrals cannot be vetoed by the governor. In the case of a citizen referendum, supporters of the referendum must obtain a specified number of signatures from registered voters. The number of signatures required is determined by a fixed percentage of the votes cast for all candidates for governor at the general election preceding the filing of the petition. Referendum petitions require four percent, currently 44,524 signatures. Any change to the Oregon Constitution passed by the legislature requires referral to voters. (See also: Initiative)
