Except as otherwise provided in these rules, the evidence in a case shall consist of the exhibits cited in the briefs or as exhibits allowed pursuant to a motion to supplement and attached thereto.

Exhibits shall be documents, portions of documents, or transcriptions of electronic records listed in the index, unless a motion to supplement the record has been granted. Exhibits admitted on motion to supplement will be assigned a number by the presiding officer.

The relevant portion of any exhibit cited in a brief or motion must be attached to the brief or motion and identified by the exhibit's index of the record (or assigned) number and number of the page cited. When such attachment is redundant, the presiding officer may allow the participants to cross-reference to exhibits attached to previously submitted materials so long as they are identified in the same manner.

This requirement will be stated in the order on motion to supplement.
