So the increase is a done deal. Except for one thing.
The toll authority is facing two lawsuits in San Francisco Superior Court, both of which challenge the validity of Regional Measure 3 on the grounds that its toll increases are a special tax.
Under the state Constitution, the plaintiffs argue, tax measures require a two-thirds majority to pass. RM3, which its proponents argue is a user fee that needed only a simple majority to pass, got a 55 percent yes vote.
