When the record is complete for purposes of transmittal, but without awaiting the filing of any transcripts, the Bankruptcy Clerk must promptly transmit to the District Clerk the motion papers and attached exhibits. After the District Court has assigned a number to the case or matter, all documents pertaining to the matter under review by the District Court must be filed with the District Clerk. The parties must continue to file all documents relating to all other matters in the bankruptcy case or adversary proceeding with the Bankruptcy Clerk.
