Facts

On 18 May 2018, the Appellant, KSY Juice Blends UK Ltd (KSY), agreed to sell water-extracted soluble orange solids (Wesos) to Citrosuco GmbH (Citrosuco) over three years (2019–2021), totalling 3,600 MT at 1,200 MT per year. For 400 MT annually, a price of €1,600/MT was invoiced, adjusted for five ‘brix’[1] and ‘free trucks’ to reduce the effective rate to €1,350/MT.[2] The remaining 800 MT per year was subject to an Open Price Provision—negotiable by December of the preceding year.[3] Only the 2019 400 MT was paid and delivered. On 27 December, KSY stated that, as no price had been agreed, the current level would be invoiced, with adjustments once agreed. Due to falling demand, Citrosuco paid for only 84 of 126 MT delivered in 2020 and argued that, absent an agreed price, none was payable. In September 2020, KSY terminated the contract for alleged repudiatory breach[4] and claimed damages.[5] The High Court held that the 800 MT invoiced at a future-determined price amounted only to an unenforceable agreement to agree.[6]

Issue

The main issues that faced the Court were threefold: whether the contract was binding or an unenforceable agreement to agree. Secondly, whether a market or reasonable price under Section 8 of the Sale of Goods Act (SOGA) could be implied into the contract or through common law, and if that price could be determined without unreasonable difficulty;[7] and, thirdly, if the term ‘to be fixed’ precluded any implied term onto a reasonable price in the absence of an agreed price.[8]

Decision

The Court of Appeal unanimously allowed KSY’s appeal; a reasonable-price term is implied for the 800MT per year and held Citrosuco in repudiatory breach.[9] The Court reasoned that both parties had intended a binding agreement, having created a long-term contract with defined quantities, delivery periods, and a fixed price for 400 MT.[10] No wording suggested certainty or enforceability depended on agreeing a future price.[11] On the second Issue, the Court concluded Section 8(2) SOGA was applicable, as it provides a mechanism for price determination and does not render contracts void if agreement fails.[12] It further held that delivery was within the parties’ competence, with prior experience of flexible pricing.[13] Wesos traded reliably at ~70% of frozen concentrated orange juice (FCOJ),[14] providing an objective standard.[15] A final element of the Court’s decision was the loss in value from the non-delivery of two thirds of the Wesos in the 2019 delivery; the Court valued this at €1.92 million per year, with the other two-thirds amounting to at least 800MT, equalling to €1.28 million per year.[16] Additionally, having a reasonable-price term implied in fact business efficacy; having the term made the contract workable commercially.[17]

 Critical Analysis

The Court’s decision is grounded in logical reasoning and broadly supported. A potential criticism is its reliance on the meaning of ‘reasonable’: the judgment depends on transparent FCOJ pricing, which provided an objective benchmark. Without such a standard, implying a reasonable-price term could create uncertainty. While the facts justified this implication, the ruling may be too broad in markets where pricing is less clear. Nevertheless, the Court convincingly treated the stable market benchmark as decisive, for a price is sufficiently certain if it can be determined by an objective standard, even if it requires factual inquiry.[18] Using commodity-market data reflects commercial realities and avoids penalising parties relying on industry-standard mechanisms.

The Court’s approach also preserved the contract’s integrity: contract law should give effect to identifiable reasonable expectations.[19] Expectations were clearly evident within this case; the contract provided for a three-year supply of specific quantities with price flexibility accounting for market volatility, so implying a reasonable price fulfilled the comprehensive nature of the contract. However, courts must not rewrite contracts simply because performance is inconvenient; this case risks blurring the line between binding and incomplete contracts. This judgment may have the effect of weakening the requirement for typical essential items, of which an agreeable price is normally one,[20] in order for a contract to be valid.

The High Court treated an open price as excluding Section 8 of SOGA, contradicting the statute’s purpose. The Court of Appeal correctly held that exclusion must be express; that commercial statutes aid, rather than frustrate, business. However, a potential risk manifesting from the judgment is one of commercial convenience; parties may rely on courts to fill pricing gaps, which empirical analysis shows firms often leave unchanged or incomplete strong incentives exist to push their refinement.[21] Courts specifying uncertain terms is inefficient; and it is preferable for parties themselves to arbitrate specific terms,[22] yet this judgment argues judicial implication is justified where intentions are clear and benchmarks exist.

Conclusion

The main risk is that the ruling could create a commercial safety net, allowing parties to bypass terms, like price, conveniently when market conditions change. Despite this, Section 8 of SOGA and the presence of a market price legitimise the Court’s pragmatism. Whatever the Supreme Court decision may be, it would need to go some way in challenging the empiricism and logic this judgment has provided.
