(a) Documents and Other Materials
At least 20 days before the first scheduled hearing date, all parties must provide all other parties with copies of all documents and other materials in their possession or control that they intend to use at the hearing that have not already been produced. The parties should not file the documents with the Director or the arbitrators before the hearing. If the parties create lists of documents and other materials in their possession or control that they intend to use at the hearing and have not already been produced, the parties may serve the lists on all other parties, but shall not combine the lists with the witness lists filed with the Director pursuant to Rule 12514(b).
(b) Witness Lists
At least 20 days before the first scheduled hearing date, all parties must provide each other party with the names and business affiliations of all witnesses they intend to present at the hearing. All parties must file their witness lists with the Director.
(c) Exclusion of Documents or Witnesses
Parties may not present any documents or other materials not produced and or any witnesses not identified in accordance with this rule at the hearing, unless the panel determines that good cause exists for the failure to produce the document or identify the witness. Good cause includes the need to use documents or call witnesses for rebuttal or impeachment purposes based on developments during the hearing. Documents and lists of witnesses in defense of a claim are not considered rebuttal or impeachment information and, therefore, must be exchanged by the parties.
(d) Explained Decision Request
At least 20 days before the first scheduled hearing date, all parties must file with the Director any joint request for an explained decision under [Rule 12904](g).
