Multilevel dimension of subsidiarity after the Lisbon Treaty. The role of institutional actors in the control of EU legislative process
In the new institutional perspective of the Lisbon Treaty both national and regional parliaments have been granted new competences in the field of subsidiarity monitoring. They faced the challenge of fulfilling new duties as “guardians” of subsidiarity in the so called “early warning system” (EWS) introduced by the Lisbon Treaty. Almost two years aft er the Treaty’s entry into force there remains a degree of uncertainty about the role of legislative chambers in the EWS. This article investigates the recent developments in the field of subsidiarity checks at the national and subnational levels in order to determine the drivers and hindering factors of the evolution towards effective multilevel parliamentary cooperation in the ex-ante EU policy control.
