If the dispute being arbitrated is about the fairness of a dismissal and a party has alleged that the reason for the dismissal relates to the employee's conduct or capacity, the parties, despite section 138(4), are not entitled to be represented by a legal practitioner in the arbitration proceedings unless-
the commissioner and all the other parties consent; or
the nature of the questions of law raised by the dispute;
the complexity of the dispute;
the public interest; and
If, in terms of section 194(1), the commissioner finds that the dismissal is procedurally unfair, the commissioner may charge the employer an arbitration fee.
