The Arbiter's remit depends on the extent the parties want him to be involved

9  The Arbiter is bound by statute to take into account matters which the parties have indicated are ones to which he must have regard - including guidance prepared by the parties - but, so as to balance the different parts of his statutory duties, he may choose to depart from that guidance if he felt that necessary to best meet his overall statutory duty. However, while he has statutory rights to information held by the partners, their associates and related third parties, the Arbiter's directions can be ignored, if both parties agree.
