I heard a little while ago, that Arizona is approaching the deadline for their legislature to close the session. If the audit is not finished by then, it would take the Gov. to call a special session - apparently not too likely.
If no special session, there will be no legislative action till January next year.
Good Qoestion. They are scheduled to adjourn July 2.

I would think they would be allowed to extend.
