Perhaps you should try some spelling variations:
weisungsbefugnis » weisungsbefugnisse, beratungsbefugnis
regelungsbefugnisse » handlungsbefugnisse, weisungsbefugnisse, ermittlungsbefugnisse
regulierungsbedarf » 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: (weisungsbefugnis OR (regelungsbefugnisse OR (regulierungsbedurfnis OR regulierungsbedarf))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(weisungsbefugnis or (regelungsbefugnisse or (regulierungsbedurfnis OR regulierungsbedarf)))".
• Adding a wildcard symbol may retrieve word variants: (weisungsbefugnis or (regelungsbefugnisse or (regulierungsbedurfnis OR regulierungsbedarf)))*.
