Using the initiative process to push through a tax increase in Nevada would become more difficult under a new ballot proposal to require approval two-thirds of those voting on such plans.
Steve Martin, a Las Vegas certified public accountant who served as state controller for about six months in 2006, filed the plan with the secretary of state's office, saying it's needed to stop "special-interest groups" seeking higher taxes.
Martin's proposal would expand a two-thirds' requirement that already exists for legislative approval of tax increases.
A pending teachers' union proposal would raise gambling taxes to help fund public education.
The proposal by the Nevada State Education Association would raise about $250 million a year for schools.
