Omnibus legislation is the legislative practice of packaging together numerous unrelated measures in one long bill, which is often passed via an expedited process. In many jurisdictions around the world, this practice has become one of the major developments in the legislative process, a powerful policy tool, and a governance device with important implications for democratic governance. It is also one of the most controversial and hotly contested legislative practices. My presentation will offer a cross-national, comparative exploration of omnibus legislation. It will draw on international experiences to explore questions such as why is omnibus legislation used and what are its governance implications. Why do different countries vary so much in their normative evaluation of this practice? And, how can the use of omnibus legislation be regulated.
