Abstract
The text presents the concept of joint-decision making as an idea and alternative to the already established concepts of centralisation and decentralisation in federal studies. Whereas the notions of centralisation and decentralisation seem to be well established in federal studies, the idea of joint-decision making seems to count only as a German speciality or a German feature of federal studies. This paper further explores this idea and concept, drawing upon the German case as well as suggesting it is worth expanding beyond it.
