Perhaps you should try some spelling variations:
regulatory decisions » regulatory decision, regulatory functions, regulatory response
regulatory regions » regulatory regimes, regulatory responses, regulatory reform
regulatory actions » regulatory functions, regulatory factors, regulatory practices

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: independent ((((regulatory decisions) OR (regulatory regions))) OR (regulatory actions)) / political aspects / european union countries.
• The words AND, OR and NOT may confuse the search; try adding quotes: "independent ((((regulatory decisions) OR (regulatory regions))) or (regulatory actions)) / political aspects / european union countries".
• Adding a wildcard symbol may retrieve word variants: independent ((((regulatory decisions) OR (regulatory regions))) or (regulatory actions)) / political aspects / european union countries*.
