The Associated Press is reporting that the state Supreme Court plans an Aug. 20 hearing on an appeal from a lower court ruling that blocked Nevadans from voting in November on three petitions backed by Las Vegas Sands Corp. owner Sheldon Adelson.

One petition would divert room tax money from the Las Vegas Convention and Visitors Authority to public education. Another would take convention authority revenue and spend it on education, transportation and public safety. The third would require a two-thirds vote to approve ballot measures that raise taxes.

Carson City District Judge Todd Russell ruled July 2 that the petitions couldn't be placed on the ballot because of problems with affidavits signed by petition circulators.
