Major Nevada casinos and a teachers union delivered more than 130,000 signatures in support of a plan to raise hundreds of millions of dollars for public schools through a hotel room tax increase in the Reno and Las Vegas areas.

The Committee for the Advancement of Education in Nevada, made up of the Nevada State Education Association, Wynn Resorts, Harrah's Entertainment and Station Casinos, more than doubled the necessary minimum of 58,628 signatures of voters around the state.

Advocates of the plan said all but about 30,000 of the signatures were delivered Monday to election officials in Las Vegas, and more than 18,000 were delivered in Reno.

The CAEN plan provides for room tax increases of up to 3 percent, to a maximum rate of 13 percent. If the signatures are verified by election officials, it would be sent to the 2009 Legislature.

If lawmakers don't approve it within 40 days, the plan goes to a public vote in 2010. If legislators decide to approve the plan, it could take effect by July 1. It would take a two-thirds affirmative vote of the Legislature to implement the increase.
