Kingdom of Lesotho v Frazer Solar GmbH and Others [2026] ZASCA 75 (22 May 2026)
A jurisdiction’s reputation as a home for international arbitration turns on a quiet discipline: its courts must be willing to enforce the consequences of the parties’ own choice, even when those consequences are unforgiving. Commercial actors who agree to arbitrate trade the open-ended remedies of litigation for finality. A seat that allows that bargain to be unpicked long after the fact offers little worth having.
On 22 May 2026 the Supreme Court of Appeal handed down its most consequential decision yet on the International Arbitration Act 15 of 2017 (the “IAA”), the statute that brought the UNCITRAL Model Law on International Commercial Arbitration into South African law. The judgment matters on two levels. It is the clearest indication to date that South African courts will hold litigants to the Model Law’s time limits without flinching, and it delivers that message in a dispute where the party defeated on the point was a neighbouring sovereign state. For a firm whose work runs daily across the South Africa–Lesotho corridor, the decision is a reminder that the region’s cross-border commercial traffic passes straight through Johannesburg’s arbitral seat.
A dispute that arrived late
The underlying transaction was a supply agreement between the Kingdom of Lesotho and Frazer Solar GmbH, a German company, for the delivery of energy-efficiency products into Lesotho. When the relationship soured, a tribunal seated in Johannesburg issued an award in early 2020 directing Lesotho to pay Frazer Solar in the region of €50 million. Lesotho took no part in the arbitration.
With its award in hand, Frazer Solar approached the High Court and had it made an order of court. Again, Lesotho did not appear. Only afterwards did the Kingdom mount a defence, and it did so along two separate fronts. The first was an application to rescind the enforcement order, on the basis that Lesotho had never validly consented to the supply agreement or to the arbitration clause embedded in it. The second was an application to set aside the award itself, resting on the same alleged invalidity.
The problem was timing. The set-aside application was launched in October 2021, the better part of two years after the award, and far outside the three-month window the Model Law permits. Lesotho’s explanation was that the entire process had been concealed from it through fraud and corruption, leaving it no chance to act sooner. The High Court was unpersuaded and dismissed both applications. The appeal followed.
Two outcomes, one award left standing
The SCA split the result. On the enforcement leg, the majority found for Lesotho. It accepted that the Kingdom had a credible account of why it had stayed away and a genuine defence carrying prima facie weight, notably, that the arbitration agreement may have been signed by a Minister who lacked authority to bind the State. The enforcement order was rescinded accordingly.
The set-aside application met the opposite fate. There the majority held that the three-month period in article 34(3) of the Model Law is peremptory. Courts have no general power to extend it, and the bar withstands constitutional scrutiny. The award therefore survived intact and beyond challenge on its merits, even as the order enforcing it fell away.
Why the three-month bar is not negotiable
At the centre of Lesotho’s case lay the proposition that a court must retain some residual discretion to forgive a late challenge, and that an absolute cut-off cannot sit easily with the constitutional right of access to courts. The Arbitration Foundation of Southern Africa intervened as a friend of the court to resist that argument, and its submissions shaped the majority’s reasoning.
The answer turned on the interpretive instructions written into the IAA itself. Section 8 invites courts to consult the UNCITRAL materials as an aid to construction, and article 2A directs them to read the Model Law with its international origin and the goal of uniform application in mind. Section 233 of the Constitution pulls in the same direction, favouring readings consistent with international law. Read together, these provisions make uniformity not a matter of preference but an obligation.
Judged against that yardstick, a locally invented power of condonation would put South Africa out of step with its peers. Leading Model Law jurisdictions, Singapore, New Zealand and Kenya among them, treat the equivalent deadline as fixed. To recognise a discretion here would make the country an outlier and corrode the very certainty that draws parties to a seat in the first place. The majority reinforced the point with the statute’s drafting history: the South African Law Reform Commission had weighed a general extension power and deliberately declined to adopt it. Where the legislature has considered an option and rejected it, the courts cannot quietly reinstate it. To let judges reopen awards at large, the majority reasoned, would invite risks heavier than any burden the deadline imposes, and would undercut article 5’s restraint on judicial interference in arbitral proceedings.
A closed door the Constitution permits
That left the constitutional objection: does barring a late applicant offend the access-to-courts guarantee in section 34? The Foundation’s primary submission was that section 34 is not engaged at all, because the time bar bites only once the parties have had their full hearing and the arbitration has run its course. In the alternative, it argued, any limitation is reasonable and proportionate, and so justified under section 36.
The majority took the alternative route. A deadline does narrow access to the courts, it accepted, but the limitation is justifiable. Parties who choose arbitration knowingly take on its trade-offs; finality and efficiency are part of what they bargain for, and a proportionate time limit is the price of securing them.
The fraud exception that went unused
South Africa did not import the Model Law’s set-aside provision unaltered. In a departure with no equivalent in the standard text, article 34(5)(b) of the IAA permits the three-month bar to be extended where an applicant proves that it did not know, until after expiry, that the award had been procured or tainted by fraud or corruption. It is a narrow, knowledge-based safety valve, designed to meet the standard objection to any hard deadline, namely that serious wrongdoing may surface only once it is too late, without throwing open the door to broad judicial discretion.
On the facts, this provision could have been Lesotho’s strongest card. Its entire narrative was one of concealment and corruption. Yet the Kingdom raised those allegations only in the enforcement challenge, not in the set-aside application, the single forum in which the exception operated. Because the carve-out was never pleaded where it mattered, it was never triggered, and the ordinary bar applied. As both the majority and the dissent observed, had the fraud and the late discovery been advanced and proven within the set-aside application, the outcome on that leg might well have differed. The lesson is a sharp one: a remedy is only as good as the application in which it is actually pleaded.
A divided bench and the road to Constitution Hill
The majority did not carry the whole court, and the two dissents are striking because they pull in opposite directions. Molemela P, with Makgoka JA concurring, would have allowed the set-aside application, reading article 34(3) as leaving room for an extension on good cause. Modiba AJA went the other way entirely, taking the view that Lesotho was in default and that the enforcement application ought to have failed. A bench fracturing along two opposing fault lines, one pressing for greater judicial latitude, the other for stricter finality, makes a further appeal to the Constitutional Court a real prospect rather than a remote one.
The award stands, but enforcement is not assured
It would be a mistake to treat the dismissal of the set-aside application as the close of Lesotho’s options. The SCA was careful to separate an attack on the award from resistance to its enforcement. Setting an award aside goes to its validity; opposing recognition under article 36 goes only to whether it will be given effect. Because the enforcement order was rescinded, Lesotho keeps the ability to contest enforcement on article 36 grounds, including the consent and authority defects it has raised, notwithstanding that the award itself remains valid and immune from set-aside.
What practitioners should take from it
For anyone advising on or litigating international awards in South Africa, the judgment carries several plain messages. The three-month set-aside window should be treated as immovable: diarise it from the date of the award and assume no rescue by way of condonation. Where fraud or corruption is in issue, the article 34(5)(b) exception must be raised in the set-aside application itself and backed by evidence of late knowledge, invoking it in some other proceeding will not save the position. And finality, the decision confirms, is not a technical obstacle to justice but a value the system is built to defend.
The approach places South Africa squarely within the mainstream of pro-arbitration jurisdictions, which tolerate only the narrowest inroads into their time limits. England offers a useful point of comparison: section 70(3) of the Arbitration Act 1996 fixes a 28-day period to challenge an award, and although section 80(5) allows an extension, the discretion is exercised sparingly. South Africa’s design embodies the same philosophy, finality as the rule, relief confined to concealed wrongdoing and in doing so strengthens its standing as a seat where awards can be relied upon.
