Among other things, the committee: consults with the debtor in possession on administration of the case; investigates the debtor’s conduct and operation of the business; and participates in formulating a plan. 11 U.S.C. § 1103. A creditors’ committee may, with the court’s approval, hire an attorney or other professionals to assist in the performance of the committee’s duties. A creditors’ committee can be an important safeguard to the proper management of the business by the debtor in possession.
