Purchaser's committee, officially appointed under 11 U.S.C. § 1102, sought approval to employ an investigator for the committee. The court determined that, in making such a request, the committee must explain the necessity for the employment, among other things. Since 11 U.S.C. § 1103(d) requires a meeting between the committee and the trustee/debtor-in-possession "as soon as practicable" after the committee's appointment, and the committee had not shown that debtor was unwilling to cooperate with it, the court denied the application on the ground that the information the committee wanted might very well be provided by debtor at that meeting.
