Cal. SHC § 8705

If any assessment heretofore or hereafter issued is void or unenforceable, for any cause, or if bonds are issued to represent or be secured by any assessments and that issuance is not effective through the curative provisions in relation thereto under the law pursuant to which the assessment was levied or under this division to make them valid and enforceable, then a reassessment may be made. The reassessment shall be made upon the demand of the owner or holder of bonds aggregating one-third of the principal amount outstanding, or upon order of the legislative body, and shall be made in the manner and form provided by the law pursuant to which the assessment was levied, without regard to whether the acquisition or improvement has been done or is proposed to be done, if any valid procedure is provided, and otherwise as provided by Chapter 19 (commencing with Section 5500) of Part 3 of Division 7.
