From the Sacramento Bee‘s Capitol Alert:

Gov. Arnold Schwarzenegger has just announced that he will call a special session in late September so legislators can consider the Commission on the 21st Century Economy’s recommendations for overhauling the state’s tax system.

An exact date for the special session has not been set, but the press release notes that the commission’s deadline for submitting its findings has been extended yet again to Sept. 20. That means legislators could be back in the Capitol just over a week after the regular session ends Sept. 11.
