Peace mediation does not take place in a legal void, but often in a norm-critical or even norm-averse environment. This book contrasts this with the fact that legal conformity contributes to successful and legitimate mediation and that mediation also needs this legitimacy because it itself exerts a lasting influence. However, this need for legitimacy cannot be satisfied without taking legal norms into account. This circumstance is explained, as are the legitimacy issues to which legal norms themselves are exposed and which thus also limit the legitimatory potential for peace mediation.
