Concurrency of powers – the exercise of jurisdiction by federal governments and constituent units in the same policy areas – is a key, if not the central, mode of governance in most federal systems today. Moreover, the experience has been that federal governments dominate the concurrent space giving rise to contestation. This volume, Concurrent Powers in Federal Systems: Meaning, Making and Managing, edited by Professor Nico Steytler, is the first to examine from a comparative perspective this crucial issue confronting both established and emerging federations. Case studies of 16 countries on five continents dissect the various manifestations of concurrency, analyse what drives this modern governance mode, and review management strategies that seek to guard against central dominance of concurrent areas.
