There is absolutely no sensible reason whatsoever not to push for an independent mediator and/or arbitrator, unless you are worried that the position you have taken could be challenged and you may end up looking a bit of a know-it-all twat. I am happy to take that risk.
"30: Are ACL willing to be bound by an agreement brokered by independent mediators or arbitrator?
ACL: No. We have put our best and final offer on the table after months of negotiation with both SISU and CCFC. It was a reasonable and generous offer, as recognised by all 3 CCFC directors in attendance on 29 January 2013, as they verbally accepted it and shook hands in confirmation. We are not prepared to make further concessions, nor do we believe that any mediator could reasonably expect that we would. The ball is in CCFC’s court. Negotiations are now at an end, and the Board of CCFC have been duly notified.
CCFC: Yes. Any Arbitrator(s) would need to look at matters such as the lawfulness of the original licence, the financial viability of ACL, monies paid to ACL for utilities/other services and the fact there appears to be no contract for these and the monies paid by CCFC to ACL during the period of the dispute."
