Perhaps you should try some spelling variations:
regelungsbefugnis » regelungsbefugnisse, regelungsbedurfnis, regelungsgefuges
regelungsbedurfnisse » regelungsbedurfnisses, regelungsbedurfnis, vergeltungsbedurfnisse
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: (regelungsbefugnis OR ((regelungsbedurfnisse OR regelungsbedurfnisse) OR regulierungsbedarf)).
• Adding a wildcard symbol may retrieve word variants: (regelungsbefugnis or ((regelungsbedurfnisse or regelungsbedurfnisse) or regulierungsbedarf))*.
