Roll call votes in the committees of the European Parliament: A new dataset

This forum article presents a new dataset on roll call votes in the committees of the European Parliament in the 2014 to 2019 legislative term. Data on roll call votes in the plenary has greatly informed research on the functioning of the European Parliament, broader legislative politics and European Union decision-making. Responding to transparency concerns about legislative decisions increasingly taken at committee level, a change of the European Parliament's Rules of Procedure introduced mandatory roll calls in committees from 2014. The article explains the context of the rule change, the data collection effort, and the data as such. A discussion of conflict across committees, party group cohesion and participation in roll call votes illustrates potential applications of the data.
