6A.  In addition to and not in derogation of any other provision in this Order, where a party has failed to establish any claim or issue which he has raised in any proceedings, and has thereby unnecessarily or unreasonably protracted, or added to the costs or complexity of those proceedings, the Court may order that the costs of that party shall not be allowed in whole or in part, or that any costs occasioned by that claim or issue to any other party shall be paid by him to that other party, regardless of the outcome of the cause or matter.
