ABSTRACT
This paper introduces the updated version of our dataset, which is the third iteration of the Decision-making in the European Union (DEU-III) dataset. We outline the DEU project before describing the dataset in detail, including the case-selection criteria, and the definitions and operationalisations of the main constructs. The paper discusses the integration of the dataset with other variables that are used in many of the contributions to this special issue and other studies. Finally, we describe validity and reliability test of the DEU-III dataset as well as some avenues for its future use by scholars.

Notes
1 The time period covered by the three datasets ranges from 1996, when the ‘oldest’ legislative proposal was introduced, and 2019, when the most recent proposal was adopted as law.
2 This variation across the 7 reported policy areas emerged from the random selection of the new 16 dossiers in DEU-III.
3 We collected the estimations of salience from the policy experts whom we interviewed. That being the case, scholars may interpret the salience scores according to one or both of the two meanings reported
