Los Angeles Mayor Antonio Villaraigosa proposed dismantling California's Proposition 13, which helped begin a nationwide anti-tax movement, in favor of a "grand bargain" that would boost levies on business property.

The Democrat who leads California's largest city called on Governor Jerry Brown not to shrink from making sweeping changes in state tax laws that Villaraigosa, 58, said could produce as much as $36 billion a year in new revenue.

Villaraigosa urged the removal of Proposition 13's limits on commercial-property assessments while retaining its cap for homes. The mayor said boosting tax revenue in the most-populous state would shore up the University of California system, promote budget stability and restore public-school funds.
