Is it permissible to waive the right to land that the legatee acquired through mediation, and leave the matter to his conscience?

Mediation is permissible and even encouraged if it is for a just cause. However, it becomes forbidden if it leads to the validation of falsehood or the nullification of truth. A mediator taking possession of land in the name of another person is an act of aggression and betrayal. The mediator must repent and return the land to its rightful owner. They should remember the severe warning against anyone who usurps even a handspan of land.
