Exercising judicial review over almost all acts of the executive branch, the Council of State's judgments may be of considerable importance, often not for the actual case judged, but for its importance in shaping legal interpretation. While France is a civil law country and there is no formal rule of precedent (stare decisis), lower courts follow the "jurisprudence constante" doctrine with regard to the Council of State. The Council's major rulings are collected into law reports and commented on by scholars; the Council's official website carries a list of comments on important decisions. The Council has shaped its own legal doctrine which consists mostly of principles deduced from cases but incorporates considerable jurisprudence derived from statutes.
