Examples of supermajority requirements:
- Parcel tax elections in California. Local parcel tax ballot measures must win a 2/3rds supermajority in order to pass.
- California school bond elections. Local school bond ballot propositions require a 55% supermajority vote to pass.
Enact state budgets
Several states require a supermajority vote to pass their state's budget:
- Arkansas. 75% of the Arkansas State Legislature must vote in favor of the state's budget for it to pass.
- California. In California, 2/3rds of the California State Legislature must vote in favor for a budget to be enacted. Proposition 25 on the November 2, 2010 ballot might overturn this requirement.
- Rhode Island. In California, 2/3rds of the Rhode Island State Legislature must vote in favor for a budget to be enacted.
Voters in the State of Washington passed I-960 in 2007, which imposed a 2/3rds requirement on the Washington State Legislature for tax increases. The state legislature overturned this initiative through the process known as legislative tampering and its supporters then qualified I-1053 for the state's 2010 ballot.
