Mediation is the process of two conflicting groups coming
together to find a middle term. It is at times the negotiation with the difference
and it is normally supervised by a person in authority who oversees and leads
the processes. If the mediation fails
them the conflict is placed under arbitration.
The process of arbitration is fully directed by an arbitrator who has
same powers as the judge but is limited to the conflict that is being solved. The
arbitrator is there to impose a final decision or come up with the resolution to
the conflict in the fairest way. He should follow justice after listening to
both conflicting side. The arbitrator is not there to find the middle term to
be agreed by the two sides.
