The appellants (sellers) and first respondent (purchaser) entered into a sale agreement containing an arbitration clause requiring disputes to be referred to arbitration under AFSA rules. The appellants claimed R4,803,558.89 from the first respondent. The first respondent admitted the debt but pleaded set-off based on losses of R5,398,394.91 allegedly suffered due to breach of warranties. The appellants took exception to the counterclaim on grounds that it was premature (failure to comply with 30-day notification requirement) and that the claim was unliquidated and could not be set-off. The arbitrator dismissed the first exception and partially upheld the second. The appellants sought to appeal this ruling to an appeal arbitrator. The first respondent objected to the appeal arbitrator's jurisdiction, arguing the appeal agreement only permitted appeals against final awards, not interlocutory rulings. The appeal arbitrator rejected this objection and proceeded to decide the merits in the appellants' favour. The first respondent then instituted review proceedings in the High Court.
