The demands of due process are present in relation to any decision made by an arbitrator during the processing of arbitral proceedings. However, relatively frequently lawyers representing the parties raise questions of due process in a threatening way, suggesting that if the arbitrator does not accept their procedural proposals the result would be a breach of due process. The lawyers do not fail to draw attention to the consequences for the enforcement of the decisions of a breach of due process. Therefore, it is of great interest to analyze and distinguish when it is justified to raise questions of due process, and when they are an abuse which the arbitrator should reject for the benefit of orderly and effective arbitral management.
