Perhaps you should try some spelling variations:
regelungsbefugnis » regelungsbedurfnis, regelungsgefuges, regelungsgefuge
regelungsbefugnisse » regelungsbedurfnisse, regelungsgefugesse, regelungsgefugese, handlungsbefugnisse, weisungsbefugnisse, ermittlungsbefugnisse
regulierungsbedurfnis » regulierungsbedarf

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (regelungsbefugnis OR (regelungsbefugnisse OR regulierungsbedurfnis)).
• Adding a wildcard symbol may retrieve word variants: (regelungsbefugnis or (regelungsbefugnisse or regulierungsbedurfnis))*.
