The administrative case law was faced with changes that led to a challenging of the guidelines followed in the judicial review of technically complex administrative assessments. Despite a lively doctrinal debate and jurispruden- tial contributions have led to a system that ensures a balance between requirements of effective protection and the disputable nature of the outcomes of technical assessments, the framework of the case law remains diver- gent. Basically, the continuity with the older and more restrictive settings takes precedence over the interpretations that are more open to a full judicial review.
