Abstract: An online dispute resolution (ODR) engine can be able to facilitate a caucus within an alternative dispute resolution of an online dispute resolution session between a neutral participant, a caucused participant, and a non-caucused participant. The alternative dispute resolution can be associated with at least one legal case. A data store can be configured to persist one or more rules associated with the alternative dispute resolution, a legal case, and a compliance artifact. The rules can be a law and a legally binding requirement. The legal case can be a civil or criminal case. The compliance artifact can include a mandatory item associated with the rules and the legal case.
