Section 21

The arbitral tribunal may require any party promptly to disclose any material change in the circumstances on the basis of which the measure was requested or granted.

The party applying for a preliminary order shall disclose to the arbitral tribunal all circumstances that are likely to be relevant to the arbitral tribunal’s determination whether to grant or maintain such order, and such obligation shall continue until the party against whom the order has been requested has had an opportunity to present his case, and thereafter subsection (1) applies.
