California Code, Health and Safety Code - HSC § 5042

Whenever it appears that the rates are insufficient to provide enough money to pay the principal and interest, in addition to the operating expenses, and the governing body neglects or refuses to fix adequate rates therefor, any bondholder may petition the superior court for a writ of mandate to compel the governing body to increase the rates to such an extent as will make them sufficient to provide enough money for those purposes.
