Perhaps you should try some spelling variations:
beratungsbefugnis » vertretungsbefugnis, verfugungsbefugnis
regelungsbefugnisse » handlungsbefugnisse, weisungsbefugnisse, ermittlungsbefugnisse
regulierungsbehorde » regulierungsbehorden

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: (beratungsbefugnis OR (regelungsbefugnisse OR regulierungsbehorde)).
• Adding a wildcard symbol may retrieve word variants: (beratungsbefugnis or (regelungsbefugnisse or regulierungsbehorde))*.
