1. Private arbitration awards conducted under the Arbitration Act may only be reviewed by the Labour Court on the narrow grounds set out in section 33 of the Arbitration Act (arbitrator misconduct, gross irregularity, or improper procurement), not on the broader reasonableness standard applicable to CCMA arbitrations under Sidumo. 2. The distinction between private arbitration (consensual and private) and CCMA arbitration (non-consensual and statutory) requires different review standards. 3. Errors of law, misinterpretation of contracts, or incorrect evaluation of evidence by a private arbitrator do not constitute grounds for review - the arbitrator has 'the right to be wrong' on merits. 4. Such errors are made within the scope of the arbitrator's mandate and do not constitute misconduct, gross irregularity, or exceeding powers. 5. A notice of withdrawal properly filed with the Registrar perfects a withdrawal, regardless of which party filed it. 6. An inadequate explanation for delay in bringing a review application, particularly where no urgency was shown and substantial periods remain unexplained, warrants refusal of condonation. 7. Where review grounds lack merit and there are no prospects of success, condonation will be refused even if the Court considers other factors beyond the explanation for delay.
