– . The General Court of the European Union held, among other things, that the respondent Research Executive Agency (the REA) had breached the principle of proportionality by declaring that all costs incurred by the applicant Universiteit Antwerpen for a researcher trained under Grant Agreement 238686 concluded within the Seventh Framework programme for research, technological development and demonstration activities (2007-2013) were ineligible. The REA had exceeded what was appropriate and necessary to offset in financial terms the applicant's infringements of the contractual obligations regarding that researcher's stay outside the applicant's premises.
