The use of omnibus legislation is increasing all around the world. This paper looks at legislative data and cases of omnibus legislation from three countries at different stages of the democratic transition process: Turkey, Indonesia and Hungary. In these countries, omnibus legislation was a tool used by dominant executives to circumvent or weaken the parliament. Omnibus legislation is a flexible tool for compromised law reforms (legal approximation of EU integration), and frequently used also for political bargaining, in order to reach package deals within the legislature (Italy, Canada, the USA). On the other hand, omnibus laws make the legislative procedure less transparent. The possibility of constant amendment packages in (negative) omnibus laws erodes legal perfection and brings uncertainty and mistakes into laws, which then call for even more amendments for corrections, creating a vicious circle.
