“In your present role are critical decisions a team exercise or one mostly dictated / handled by management?”
Whatever the answer the next questions should focus on the candidates feelings about that approach. As for the style in place at their present employer — perhaps a question along the lines of how they would have major decisions made if they were in charge will yield some insight into the candidate. Are they comfortable being a worker bee with direction from the top or a contributor on the task and the decision level? Probing on all angles will yield some terrific understanding of your candidate’s perspective.
