Some legal cases in complex societies might be so difficult to decide in the highest court that "arbitration" should be mandatory if the original descision is not significantly unanimous (e.g., at least 6/3 of 9 justices).
For evolution of this concept, the justices themselves might decide before deliberations whether or not to activate the arbitration mandate for the case. The ultimate goal of such arbitration would be to convince society that a non-significantly-unanimous decision is well-deliberated, reasoned, and just.
