On July 6, 2017, the Supreme Court of California held that landowners could not contest unfavorable permit conditions because they had proceeded with construction during the litigation, forfeiting their challenge. (Lynch v. California Coastal Commission, Case no. S221980 (Cal. 2017)). The court reached this conclusion even though the owners had proceeded with construction under protest and even though the permit was for a protective seawall that could not wait for litigation.
