What happens in mediation stays in mediation due to the highest degree of confidentiality and the Without Prejudice principle applicable. First, unlike litigation or arbitration, mediation goes mainly off the record. Then, communication in mediation is classified as Strictly Confidential and prohibited from being used as evidence. Moreover, generally, a mediator cannot be called as a witness on the matter mediated. It indeed provides the safest legal setting for any negotiation to settle.
