Proceedings for the transfer of an action under this section may be initiated by
(i) the judicial panel on multidistrict litigation upon its own initiative, or
(ii) motion filed with the panel by a party in any action in which transfer for coordinated or consolidated pretrial proceedings under this section may be appropriate. Before cases are designated multidistrict litigation and transferred to one federal court, the Panel convenes a hearing and notifies all parties of the place and time of the hearing. The Panel’s order of transfer is based on a record of such hearing at which material evidence may be offered by any party to an action in any federal court that would be affected by the transfer.
