By country
France
Under Article 46 of the Constitution of France, organic laws are a short, fixed list of statutes specified in the Constitution. They overrule ordinary statutes. They must be properly enacted by the Parliament of France following a special procedure and must be approved for constitutionality by the Constitutional Council of France before they can be promulgated.Organic laws allow flexibility if needed. An important category of organic laws includes the budgets of the French state and French social security. Other organic laws give the practical procedures for various elections. Organic laws reduce the need for amendments to the constitution.
