The parties shall be given sufficient notice in advance of any hearing and of any meeting of the arbitral tribunal for the purposes of inspection of documents, goods or other property.

All statements, documents or other information supplied to the arbitral tribunal by one party shall be communicated to the other party.

Any expert report or evidentiary document on which the arbitral tribunal may rely in making its decision shall be communicated to the parties.
