According to a recent Holland & Knight study based on published CEQA opinions from 1997 to 2012, more than half of the challenged projects in cases reviewed were infill development projects. Holland & Knight based its conclusions on a review of 95 published Court of Appeal and California Supreme Court decisions. The firm’s analysis also concluded that, in those published cases, more than a third of projects challenged were public works projects. The most commonly-challenged types of projects, according to the study, involved public infrastructure (19%) and mixed-used developments (19%). These results do not include any analysis of unpublished Court of Appeal cases.
