Court denied, without prejudice to the filing of a supplemental application, the third interim application for compensation and reimbursement of expenses of the trustee's attorney. It is within Court's sound discretion to decline to award compensation until all relevant circumstances and factors affecting the determination of fair and reasonable compensation for the attorney are known.  Court also questioned the firm's entitlement to any compensation for litigation in light of the failure of the trustee to seek approval of the Court for the firm's retention to provide such services.
