Why must a lawyer resign if the other side decides to go to court?

The requirement that all lawyers be disqualified in the event of a breakdown guarantees that all participating counsel will be totally and exclusively motivated to make the process succeed. Thus, all participants are equally and fully invested in finding the solutions to all problems. More subtly, it is believed that the way people participate in negotiation, and especially the way lawyers participate, is affected by the certainty that lawyer will never litigate the case. Openness, candor, and cooperation replace guardedness, secrecy, and threats as the techniques most likely to achieve ultimate success. Walking out in anger, or provoking the other side to, ceases to be a viable tactic.
