Conduct of creditors' meetings: trustee convenes, sets quorum, may form committee and records minutes. The bankruptcy trustee is the convener and presiding officer for creditors' meetings, decides and enforces the quorum and may conduct the meeting only when that quorum is present; the meeting may establish a committee of creditors and transact other business the trustee deems fit; the trustee must record, sign and retain the minutes as part of the bankruptcy records, and may not adjourn the meeting for more than a short limited interval at a time.
