South African courts enforce the adjudicator's decisions immediately, even if a party intends to challenge the outcome through arbitration. If your construction contract specifies the decision as binding, compliance is not optional. Disputes about eligibility come later – payment and performance come first.
Why does adjudication exist and what do courts do with it
The adjudication was designed to keep construction projects going. Disputes over payment or performance cannot allow a project to be stalled for months or years, requiring arbitration or litigation.
The adjudication mechanism quickly renders a binding interim award, with the final resolution being deferred to arbitration if either party remains dissatisfied.
South African courts have aligned themselves strongly with this objective. In Esor Africa (Pty) Ltd/Frankie Africa (Pty) Ltd Joint Venture v Bombella Civils Joint Venture (Pty) LtdThe court confirmed that the arbitrator's decisions are binding and enforceable unless modified by arbitration.
Applying a purposive interpretation of the International Federation of Consulting Engineers (FIDIC) dispute resolution provisions, the Court held that section 20 DAB decisions have interim enforceability – not final – and contractors must continue to work while employers must make immediate payment.
This position has been continuously strengthened. In Tubular Holdings (Pty) Ltd vs DBT Technologies (Pty) LtdThe Court reaffirmed that filing a notice of dissent preserves the right to arbitrator but does not suspend the arbitrator's obligation to comply with the decision in the interim.
The obligation to respect decisions “without delay” was underlined in the context of Basil Reed (Pty) Ltd v Regent Devco (Pty) LtdAnd the interim-binding principle was further confirmed Stocks & Stocks (Cape) (Pty) Ltd v Gordon.
the important thing is Sasol Chemical Industries Ltd. v. Odell and Others Confirmed that an adjudicator's decision remains enforceable even where it contains errors of law. Mistakes of law do not affect the adjudicator's jurisdiction, and courts will not refuse enforcement on that basis alone.
Two exceptions: when courts will refuse to enforce
While the default position is enforcement, courts recognize two narrow grounds on which an adjudicator's decision will not be upheld.
1. Exceeding Jurisdiction
An adjudicator's authority is defined by the referral notice. If the adjudicator makes a decision beyond what is specified, or changes the terms of the contract beyond the authority given, they have exceeded their jurisdiction and the decision is unenforceable.
Frematome v Eskom Holdings SOC Ltd This clearly shows. The court upheld the adjudicator's first decision, finding that it fell within the mandate. It refused to enforce the second award because the adjudicator had answered a question not referred to under the contract – a textbook jurisdictional overreach.
Coppin J confirmed that enforcement should be carried out unless there is a clear case that the adjudicator decided an issue which was not referred to him. Where the situation is not clear, the interim decision will stand and must be followed.
Group Five Construction (Pty) Ltd v Transnet SOC Ltd Provides another important example. The contract requires the adjudicator to publish his decision within four weeks of receiving the final submission, with any extension requiring mutual consent.
The employer refused to grant an extension, but the adjudicator issued his decision regardless of the deadline. The court considered this a jurisdictional flaw – by acting after its authority had expired, the adjudicator exceeded the mandate given by contract, and the decision was unenforceable.
2. Violation of natural justice
Where an adjudicator proceeds without the participation of a party or refuses to give a party a reasonable opportunity to present its case, enforcement will fail.
In Group Five Construction vs TransnetThe court also refused enforcement on this basis, holding that natural justice requires both fairness and equal opportunity to be heard. Procedural fairness is not a technicality – it is a core requirement.
What does this mean for how you formulate and run decisions
Case law makes it clear that a decision is only as reliable as the process used to implement it. The courts will enforce decisions that fall within the adjudicator's jurisdiction and have been reached impartially.
They will not save the flawed process.
On formatting:
Referral notice must be accurate. The adjudicator's jurisdiction is defined by your context. Vague or broad referrals create risks – either the adjudicator makes some decision beyond the referral, or the court later finds that the mandate has been breached.
Timeline provisions matter. If your contract specifies a decision deadline and any extension requires mutual consent, treat this as a hard limit. As group five demonstrates, an adjudicator who ignores this produces an unenforceable decision.
Make sure the binding language is clear. Courts enforce arbitration clauses where the contract explicitly specifies the award pending arbitration. Ambiguity in this section creates unnecessary enforcement litigation.
On compliance:
Notice of dissatisfaction does not suspend your obligation to comply. Pay first, arbitrate later.
If you believe an adjudicator has exceeded his or her jurisdiction, seek legal advice immediately.
The bar for establishing a jurisdictional challenge is high – courts require a clear and respectable case. General disagreement with the outcome will not accomplish this.
Document procedural objections as they arise. If natural justice concerns exist, raise them during the process, not just when enforcement is being sought.
The South African situation: a summary
South African law on adjudication enforcement can be stated clearly:
The rule is for immediate compliance. Judgments bind the parties from the moment they are issued and are fully enforceable by our courts, regardless of whether a notice of dissent has been filed or arbitration is pending. Errors of law in the decision do not change this.
Exceptions are narrow and strictly enforced. An award will only be refused enforcement where the arbitrator has clearly exceeded his jurisdiction – by deciding a dispute that has not been referred, acting after his authority has expired, or changing the terms of the contract beyond his mandate – or where there was a material breach of natural justice.
Getting it wrong has consequences on both sides. A party that refuses to comply risks court-ordered enforcement and adverse costs. An adjudicator who violates his mandate or fails to follow fair process is likely to render a decision that the courts will refuse to uphold, leaving the party in the same situation.
Arbitration only works when the parties use it appropriately. Draft referral notices carefully, respect procedural deadlines and treat compliance as the default – not a fallback.
