If no proceedings have been brought by the public agency pursuant to this chapter, any interested person may bring an action within the time and in the court specified by Section 860 to determine the validity of such matter. The public agency shall be a defendant and shall be served with the summons and complaint in the action in the manner provided by law for the service of a summons in a civil action.
