Does the late filing of a complaint in an intervention action require the respondent to respond to the complaint within the time set out in the summons?

The Green court held that because the validation statutes provide the exclusive method for interested parties to enter such actions, it would not permit the late filing of the complaint in intervention. (Green v. Community Redevelopment Agency, supra, 96 Cal.App.3d at pp. 495, 498, 500, 158 Cal.Rptr. 126; see also 861.1 and 862 which require responses to be filed no later than the time set forth in the summons.)
