Two proposed measures for the November ballot in Arizona are awaiting state Supreme Court action.

One is the open primary, in the form of a proposed state constitutional amendment that would change the way elections are held. Tuesday is the deadline for both sides to complete filing their written arguments.

The other is the one-cent sales tax, in the form of a proposed initiative that would create a permanent education funding source. Written arguments have been filed, and the court is considering a request for oral arguments.

In addition, the Arizona Education Parent Network, which is behind the one-cent sales tax, is awaiting action on a lawsuit challenging the legislatively adopted wording that summarizes the measure in the state's official election literature.

All three of the court actions must be decided soon to give elections officials in the state time to get brochures printed and ballots prepared.

In the open-primary case, supporters of the measure asked the Supreme Court to overturn a Superior Court decision keeping it off the ballot on a claim it addresses more than one constitutional issue. Under the state constitution, a ballot measure aimed at amending the constitution can address just one issue.

Under the open primary, all voters would be able to vote for any candidate in primary elections, with candidates' party designations optional. The top two, regardless of party, would face off in the general election.

The one-cent sales tax proposal would permanently replace the current one-cent education sales tax, which will expire at the end of May 2013. The new proposal calls for 80 percent of the tax's proceeds to go to public education at all levels.

The current one-cent sales tax brings the state about $900 million annually, and the new tax would be expected to do the same.
