Perhaps you should try some spelling variations:
weisungsbefugnis » weisungsbefugnisse, beratungsbefugnis
regelungsbefugnisse » 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: (weisungsbefugnis OR (regelungsbefugnisse OR regulierungsbedurfnis)).
• Adding a wildcard symbol may retrieve word variants: (weisungsbefugnis or (regelungsbefugnisse or regulierungsbedurfnis))*.
