Joint control in the European Union Law
Concept of Joint control provided by the “Glossary of terms used in EU competition policy” (Antitrust and control of concentrations, published in 2002): Joint control exists where two or more undertakings or persons have the possibility of exercising decisive influence over another undertak-ing. Decisive influence in this sense normally means the power to block actions that determine the strategic commercial behaviour of an undertaking. Joint control can be acquired legally or de facto.
