How routine contractual restraints can trigger SA competition riskA question that arises regularly in commercial practice is when ordinary contractual restraints – such as non-competes, exclusivity agreements, supply commitments, settlement terms and joint venture obligations – risk characterisation as horizontal market division under the South African Competition Act 89 of 1998 (as amended) (Act). ![]() Image source: Denis Ismagilov – 123RF.com The issue is not always obvious, as restraints of this nature are often included in ordinary commercial agreements for legitimate reasons, including the protection of confidential information, transaction-specific investment, goodwill, know-how or the integrity of a broader commercial arrangement. However, where a restraint operates in substance to allocate customers, suppliers, territories or specific goods or services between actual or potential competitors, it may attract scrutiny under section 4(1)(b)(ii). The regulatory frameworkSection 4(1)(b) of the Act prohibits a defined set of horizontal practices between firms in a horizontal relationship, including the allocation of customers, suppliers, territories or specific goods and services. The prohibition is per se, in that there is no rule-of-reason inquiry, and unlike section 4(1)(a) - no opportunity to demonstrate offsetting efficiencies or pro-competitive effects. Once the conduct is properly characterised as falling within section 4(1)(b)(ii), liability follows without further balancing. The contested issues, in practice, are accordingly threefold:
Each of these is a matter of substance over form – a principle the Competition Tribunal and Competition Appeal Court have consistently reinforced. A clause does not escape section 4(1)(b)(ii) merely because it is housed in a supply contract, a distribution agreement, a settlement, a licence or a joint venture document, and an arrangement need not be reduced to writing to qualify as an agreement or concerted practice for purposes of the Act. Of these three elements, the characterisation of the parties’ relationship is often most contended – and the most consequential – in practice. When are parties “horizontal”?This is the analytical heart of most cases of this nature, as a relationship can be vertical in one respect and horizontal, or potentially horizontal, in another. A supplier, distributor, technology partner, licensee or joint venture participant may also be an actual competitor or potential competitor of its counterparty if it has the capability, incentive and reasonable strategic option to enter the adjacent market. The “potential competitor” maxim matters particularly here, as a firm need not currently sell into a market to be a potential competitor; it is enough that, but for the restraint, the firm could realistically have entered within a reasonable timeframe, with the assets, capabilities and intent to do so. The factors that typically inform this assessment include the firm’s existing technical and operational capabilities, the barriers to entry in the relevant market, the firm’s financial resources and strategic priorities, and any contemporaneous evidence of an intention to enter, such as internal strategy documents, board approvals, product development activity or commercial overtures to prospective customers. A clause does not lose its character merely because of the document in which it appears, and the question is not how the parties describe their relationship in the recitals but how it looks when one asks whether each party could realistically have competed with the other absent the restraint. Understanding whether parties are horizontal is only part of the inquiry. The next question is where, in the architecture of a commercial transaction, market-division risk is most likely to arise. Where the risk hidesMarket-division risk in commercial contracts is rarely labelled as such, and it tends to surface in clauses serving other apparent purposes, such as:
None of these structures are inherently unlawful, and each requires a competition law overlay that asks whether, in substance, the restraint allocates markets, customers, suppliers or services between actual or potential competitors. The evidentiary significance of internal correspondence and contemporaneous deal documentation should not be underestimated, as the way in which a restraint is described in negotiation correspondence, board memoranda and internal communications often informs how it is later characterised. For example, language framing a restraint in terms of parties “staying in their lanes” or “not stepping on each other’s toes” can be prove deeply problematic at the evidentiary stage, revealing an allocative intent that more carefully calibrated contractual drafting cannot retrospectively cure. The ancillary restraints questionThe proper test is thus not whether a restraint exists, but whether it is genuinely ancillary to a legitimate purpose and proportionate to the protection that purpose requires. For instance, a restraint protecting confidential information, the value of a business sold as a going concern, transaction-specific investment or the integrity of a bona fide collaboration is more readily defensible than one that prevents entry into a market unrelated to the core transaction, lasts longer than necessary, sweeps across overly broad territories or customer groups, or shields a party from competition generally. The questions to ask are therefore:
The proportionality of each limb of the restraint matters, and a restraint that is broader than necessary in any one respect (whether duration, geographic reach, product scope or customer category) will be more difficult to defend, even where its underlying purpose is legitimate. A restraint that cannot survive these questions is unlikely to be defensible as ancillary. Practical implicationsFor in-house counsel and transaction advisors, four key points carry through:
ConclusionThe central point is that competition law risk in South Africa is not confined to obvious cartel conduct. It can also arise from restraints embedded in ordinary commercial agreements, particularly where a supplier, distributor, customer, licensee or strategic partner is also an actual or potential competitor. Drawing the line correctly – at the drafting stage, in contemporaneous documentation and across the full portfolio of commercial agreements – is the most reliable way to keep legitimate commercial restraints on the right side of the Act, and to avoid the firm-level and individual consequences that may follow from a contrary finding.
