If employees disagree about the legality of a move or the interpretation or application of a directive, then the employee preceding the one moving is to be the Arbiter and decide the question. Disagreement for the purposes of this directive may be created by the insistence of any employee. This process is called invoking Arbitration.

When Arbitration has been invoked, the next employee may not begin his or her turn without the consent of a majority of the other employees.

The Arbiter's ruling may be overruled only by a unanimous vote of the other employees taken before the next turn is begun. If Arbiter's ruling is overruled, then the employee preceding the Arbiter in the playing order becomes the new Arbiter for the question, and so on, except that no employee is to be Arbiter during his or her own turn or during the turn of a team-mate.

Unless a Arbiter is overruled, one Arbiter settles all questions arising from the game until the next turn is begun, including questions as to his or her own legitimacy and jurisdiction as Arbiter.

New Arbiters are not bound by the decisions of old Arbiters. New Arbiters may, however, settle only those questions on which the employees currently disagree and that affect the completion of the turn in which Arbitration was invoked. All decisions by Arbiters shall be in accordance with all the directives then in effect; but when the directives are silent, inconsistent, or unclear on the point at issue, then the Arbiter shall consider company-custom and the spirit of the company before applying other standards.
