If the Arbitrator decides the matter, which are excluded by the agreement, he commits a misconduct. It comprises a legal misconduct, which is completed if the Arbitrator on the face of the award arrives at an inconsistent conclusion even on his own finding or arrives at a decision by ignoring very material documents which throw abundant light on the controversy to help a just and fair decision. It is in this sense that the Arbitrator could misconduct the proceedings in a case. Further, an award could be set aside if it is improperly procured or is otherwise invalid. Misconduct means a legal misconduct in the judicial sense arising from some honest, erroneous, breach and neglect of duty and responsibility on the part of Arbitrator causing miscarriage of justice.
