Lawmaking procedures and formal and substantial characteristics of law is a significant matter of the democratic state based on the rule of law. A legal order based on the democratic rule of law requires laws to be clear, precise, explicit, and forseeable, and contain holistic and noncontradictory provisions. In addition, the efficient representation of the nation in the parliament can only be possible if members of the parliament and the public can properly examine the bills and express their views on them. The omnibus law method loads together numerous unrelated matters in one long bill, which is often passed via an accelerated process. It is often used in many countries, including Türkiye, and is also one of the most controversial and contested legislative practices. This paper discusses the concept of the quality of law and its basic features in a democratic state based on the rule of law; the concept, subject matter, features, advantages, and disadvantages of the omnibus law method, and the legal tools to limit or repeal this method in a comparative perspective.
