The author thinks that the advantage of the arbitration procedure is its celerity, and so any incident that constitutes a risk to this must be dealt with prudently when the law establishes a binding deadline for issuing the award. The suspension of the procedure by a criminal prejudicial proceeding is not automatic, as this would be equivalent to the termination of the arbitration, but requires some conditions such as accreditation by the litigant and decisive interconnection, that is, to prove a precise objective link between the facts subject to criminal procedure and arbitration. This must be solidly supported by the arbitrator in each case to avoid suspensions that, if not justified, would mean the abusive use of the criminal proceeding by the litigants and, with it, the violation of the constitutional right to effective judicial protection.
