I've been following numerous discussions on mediation ethics on a couple of ADR listserv's.  As a result, I can tell you there are a lot of ethical questions circulating among mediators, many of them too important to remain the subject of private discussion.

So I'm pleased to announce that the ABA has formed a new committee -- the Committee on Mediator Ethical Guidance.  According to the most recent ABA e-newsletter, the Committee

will provide advisory responses on ethics for mediators. Established by the ABA Section of Dispute Resolution, the committee will interpret the 2005 Model Standards of Conduct for Mediators published by the ABA, American Arbitration Association and Association for Conflict Resolution.
