How can the arbitration process be classified?

As professor Cristian Maturana (a Director of the CAM Santiago) advocates, the arbitration process can be classified from different points of view. Depending on how the procedure is administered and the arbitrator depending how it is appointed, the arbitration may be institutional (in the case of the CAM Santiago) or ad hoc. Depending on the subject matter of the arbitration, it can be forced, prohibited or optional. According to the way in which the arbitrator resolves the conflict, the arbitration can be based on the law or on fairness.
