From the time a party files its initial pleading in a proceeding, that party must serve and all other parties must serve all future documents listed in Rule 51 upon all other parties' representatives designated pursuant to Rule 41, unless otherwise directed by order or notice or by the presiding officer on the record. The Commission may order parties to serve past documents filed in the case upon those representatives. The Commission may order parties to serve past or future documents filed in the case upon persons not parties to the proceedings before the Commission.
