‘Third Party Ethics in the Age of the Fourth Party’ presents and discusses some of the ethical impacts of the use of information and communication technology (ICT) in third party practice (mediation, facilitation, arbitration, etc.). The article argues that all of the ethical requirements related to third party practice have been affected by the use of ICT, that ethical standards of practice must be reviewed in light of the use of ICT, and that changes in ethical requirements based on the use of ICT will be evolutionary, not revolutionary.
