Supporters of a 1-cent sales tax initiative are challenging the Arizona Secretary of State's decision to disqualify it from the November ballot.
Secretary of State Ken Bennett disqualified the initiative from the November ballot, saying it doesn't meet legal requirements.
The Quality Education and Jobs campaign said it intends to file a lawsuit Wednesday in Maricopa County Superior Court, asking for a review of the more than 290,000 voter signatures it filed Monday.
A minimum of 172,809 valid signatures were required by the July 5 deadline.
Bennett says the language on the initiative circulated to voters didn't match the version pre-filed with his office.
Campaign chairwoman Ann-Eve Pedersen says the group filed the correct copy electronically and complied with all requirements of the state Constitution. They have retained a former Arizona Supreme Court justice to represent them.
Revenue from the tax would be directed to education, health care and other state services.
The increase would take effect after a previously approved temporary increase expires in mid-2013.
