Dataset containing descriptions of cases involving challenges to EU merger decisions, including the relationships of complainants to merging parties. It comprises data from 22 merger cases (between 1994-2009). The data is sourced from CJEU judgments published on the European Union’s CURIA database., which the creators have interpreted and summarised within the table of cases. The ESRC Centre for Competition Policy (CCP) at the University of East Anglia (UEA) undertakes interdisciplinary research into competition policy and regulation that has real-world policy relevance without compromising academic rigour. It prides itself on the interdisciplinary nature of the research and the members are drawn from a range of disciplines, including economics, law, business and political science. The Centre was established in September 2004, building on the pre-existing Centre for Competition and Regulation (CCR), with a grant from the ESRC (Economic and Social Research Council). It currently boasts a total of 26 faculty members (including the Director and a Political Science Mentor), 4 full- and part-time researchers and 23 PhD students.

This dataset has been compiled to calculate the proportion of cases where the Court of Justice of the European Union (CJEU) has granted standing (locus standi) to parties in challenged to the European Commission’s EU-level merger decisions. The spreadsheet consists of data from 22 merger cases (between 1994-2009) and records a number of variables of potential significance (including: the relationship of the applicant to the merging parties, the reasons for standing put forward by the applicant, and the theories of harm relating to the merger in question). The data in the table is sourced from CJEU judgments published on the European Union’s CURIA database. The creators have interpreted the qualitative data from CJEU judgments and summarised these within the table. Further details in attached documentation.
