a Magistrate Judge pursuant to 28 U.S.C. §§ 144 or 455 shall be made to the
assigned District Judge. If such a motion is filed in a case to which no
District Judge has been assigned, the motion shall be assigned to a District
Judge for decision. A copy of the motion shall be submitted to the assigned
Magistrate Judge, who shall not proceed with the matter until the motion has
been determined. If the District Judge denies the motion, the case shall
proceed as originally assigned. If the District Judge grants the motion, the
case shall be returned to the Clerk for reassignment.
