Cal. Sts. & High. Code § 9534.5

If the legislative body finds that protests against the proposed refunding or the proposed reassessments are signed by the owners of more than one-half of the area of the land proposed for reassessment, all further proceedings under the resolution of intention to refund are barred, and no new resolution of intention for the same refunding may be passed within six months after the decision of the legislative body on the hearing, unless the protests are overruled by an affirmative vote of four-fifths of the members of the legislative body. The legislative body may confirm, modify, or correct the proposed assessment.
