Where a declaration of ineffectiveness is made, the concession contract is to be considered to be prospectively, but not retrospectively, ineffective as from the time when the declaration is made and, accordingly, those obligations under the concession contract which at that time have yet to be performed are not to be performed.

Paragraph (1) does not prevent the exercise of any power under which the orders or decisions of the Court may be stayed, but at the end of any period during which a declaration of ineffectiveness is stayed, the concession contract is then to be considered to have been ineffective as from the time when the declaration had been made.

Such an order may, for example, address issues of restitution and compensation as between those parties to the concession contract who are parties to the proceedings so as to achieve an outcome which the Court considers to be just in all the circumstances.

Paragraph (6) applies where the parties to the concession contract have, at any time before the declaration of ineffectiveness is made, agreed by contract any provisions for the purpose of regulating their mutual rights and obligations in the event of such a declaration being made.

In those circumstances, the Court must not exercise its power to make an order under paragraph (3) in any way which is inconsistent with those provisions, unless and to the extent that the Court considers that those provisions are incompatible with the requirement in paragraph (1) or (2).
