National parliaments have been widely perceived as the losers of European integration, rubber-stamping legislation originating in Brussels. Ian Cooper’s article “A yellow card for the striker: national parliaments and the defeat of EU legislation on the right to strike” published in the Journal of European Public Policy disputes these assessments and demonstrates the potential of the Early Warning Mechanism, adopted by the Lisbon Treaty, to help national parliaments become “a collective force in European politics”. The article won the “PADEMIA Award for Outstanding Research on Parliamentary Democracy in Europe” at PADEMIA’s second annual conference.
