Former Mediator Seeks Later Representation
Tanner Thompson mediated a contract dispute between Topaz Mining and Trinity Pharmaceuticals. Two years later Topaz Mining asks Tanner to represent it in litigation against Trinity over the same supply agreement. Tanner may not accept the engagement because he participated personally and substantially as a mediator in the matter and no party has given informed written consent.

Common questions
Frequently Asked
4
What conduct qualifies a lawyer as a third-party neutral?+
A lawyer qualifies when assisting two or more nonclients to resolve a dispute between them, such as by serving as a mediator or arbitrator. The lawyer must not form an attorney-client relationship with any participant and must remain impartial throughout the process.
Supporting sources
Must a lawyer serving as a third-party neutral correct misunderstandings about the lawyer's role?+
Yes. When the lawyer knows or reasonably should know that an unrepresented party does not understand the neutral role, the lawyer must explain that the lawyer is not representing that party and must distinguish the neutral function from representation of a client.
Supporting sources
When is a former third-party neutral disqualified from later representation?+
A lawyer who participated personally and substantially as a mediator or other neutral in a matter may not later represent anyone in connection with that same matter unless every party gives informed consent confirmed in writing.
Supporting sources
Does joint retention by the disputing parties establish the third-party neutral role?+
Joint retention supports the neutral characterization because it shows the lawyer was not engaged by either side alone and therefore did not enter an attorney-client relationship with any participant.
