The book is concerned with the role that national parliaments of EU Member states have had as a collective actor in the EU political system. The publication explains the historical development of
this actorness and analyses its current form. In this regard, this monograph evaluates the use of
instruments that have been provided to the national parliaments by the Lisbon Treaty. It explains
why and to what extent parliaments participate in the collective scrutiny. The main finding of the
book is that parliaments primarily understand their collective actorness as a brake to further
European integration. Academic findings of the book are also set in the general political context
stressing the need to improve the effectiveness of parliaments´ collective actorness.
