The state Republican Party is proposing term limits for state legislators and a rule requiring all tax hikes be approved by a supermajority in the state House.

Those and other proposals were outlined Sunday at a GOP post-primary election rally at party headquarters in Honolulu. Many Republican legislative candidates are expected to run on the platform during the fall campaign.

The plan does not specify how many votes would be required in the House to approve a tax increase. But it could be similar to California’s law, which requires tax hikes and the state budget be approved by a two-thirds majority in both houses.

The GOP plan also calls for limiting state senators to two four-year terms and representatives to four two-year terms.
