A judge granted a trustee's application for an F.R.B.P 2004 examination. Later, but before the depositions have been taken, the trustee opens an Adversary proceeding. Does the trustee now have to follow the rules of discovery for an adversary case or is he still entitled to the broad "fishing expedition" granted in the Rule 2004? What rules apply to this and what arguments can be used to oppose the 2004 examination?
