Aranda Textile Mills (Pty) Ltd and Mzansi Blanket Supplies (Pty) Ltd v Competition Commission of South Africa

The Competition Commission referred a complaint to the Competition Tribunal alleging that Aranda Textile Mills (Pty) Ltd (Aranda), a blanket manufacturer, and Mzansi Blanket Supplies (Pty) Ltd (Mzansi), a blanket distributor, colluded in their bids for a National Treasury tender (RT26-2015T) for blanket supplies. The Commission alleged price fixing and collusive tendering under sections 4(1)(b)(i) and (iii) of the Competition Act 89 of 1998. The allegation was based primarily on circumstantial evidence: (1) Mzansi's prices consistently reflected a 7.25% mark-up on the prices Aranda quoted to it; (2) Aranda provided Mzansi with significantly lower prices (56% lower) than it quoted to other bidders such as Vilankosi Enterprises; (3) communication between the parties including a checklist of tender documents and a "let's get it done" email from Dr Mansoor (Ms Paruk's husband) to Aranda staff; and (4) a 2012 manufacturing agreement between the parties. Aranda was the only manufacturer that could supply blankets meeting tender specifications. Aranda and Mzansi had a long-standing supplier-distributor relationship. Mzansi ultimately won the tender based on superior BBBEE credentials despite Aranda's lower bid. The complaint was initiated by Mr Vilikazi of Vilankosi, who discovered he received less favorable pricing from Aranda than Mzansi did.

• Whether the Competition Commission proved on a balance of probabilities that Aranda and Mzansi contravened section 4(1)(b)(i) and (iii) of the Competition Act by engaging in price fixing and/or collusive tendering
• Whether inferential reasoning can be used to establish a per se prohibition under the Competition Act in the absence of direct evidence
• Whether communication between a manufacturer and distributor concerning pricing automatically constitutes horizontal conduct subject to section 4(1)(b) prohibitions
• Whether the Competition Tribunal properly characterized the conduct as horizontal rather than vertical given the supplier-customer relationship between the parties
• Whether the Tribunal departed from the case pleaded by the Commission and improperly supplemented deficiencies in evidence
• The proper application of evidential principles and burden of proof in competition law cases based on circumstantial evidence

The appeal was upheld with costs including costs of two counsel. The Competition Tribunal's order of 4 December 2020 was set aside and replaced with an order dismissing the Competition Commission's Complaint Referral against both Aranda Textile Mills (Pty) Ltd and Mzansi Blanket Supplies (Pty) Ltd. The Competition Commission was ordered to pay the costs of both appellants.

A finding of prohibited cartel conduct under section 4(1)(b) of the Competition Act, even where based on inferential reasoning due to absence of direct evidence, must be founded on proven primary facts from which the only reasonable inference is the existence of the prohibited agreement or concerted practice. Inferential reasoning in competition law must adhere to established evidential principles: there can be no proper inference unless there are objective, proven facts from which to infer the fact sought to be established. The inference must be consistent with all proven facts and exclude other plausible explanations. Where parties present direct evidence denying collusion, that evidence must be considered and reasons given if it is rejected. The Commission bears the burden of proving a contravention on a balance of probabilities. Proper characterization of conduct is essential in all section 4 cases to determine whether parties are truly in a horizontal relationship and whether the conduct falls within the object of the prohibition. Communications between a manufacturer and distributor concerning pricing do not automatically constitute horizontal conduct subject to section 4(1)(b); such relationships must be analyzed in their proper commercial context. The Tribunal cannot supplement deficiencies in the Commission's case by introducing theories not pleaded or by hypothesizing about collusive schemes not supported by evidence. Constitutional principles of legality and fair hearing apply to Competition Tribunal proceedings and require rigorous, reasoned analysis of all evidence.

The Court made several important observations: (1) In modern commerce, discussions between manufacturer and retail distributor on price are routine when giving or obtaining prices between them, and forcing uniform pricing to all customers may not be appropriate; (2) While cartels may be difficult to prove with direct evidence, requiring reliance on circumstantial evidence, this does not lower the standard of proof or excuse adherence to proper evidential principles; (3) Circumstantial evidence in competition cases can be divided into communication evidence and economic evidence, with economic evidence generally requiring expert testimony to avoid ambiguity; (4) The "best possible explanation" test, if used as the sole yardstick in per se contraventions, is subjective and can become a "blinker" that causes adjudicators to overlook objective facts; (5) The flexibility allowed in Tribunal proceedings is not intended to permit abuse of process and must not compromise requirements of legality; (6) Competition law should not unnecessarily hamper or obstruct pro-competitive and genuine commercial transactions; (7) Per se prohibitions, while not requiring proof of anti-competitive effects, still require proper characterization to avoid "false positives" where conduct appears to contravene but does not truly fall within the object of the prohibition; (8) Cross-examination tactics that prevent witnesses from properly reviewing documents before being questioned about them can amount to unfair entrapment. The Court also noted that the late Acting Judge President BJ Mnguni heard the matter but judgment was delivered after his passing.

This case establishes important principles for South African competition law regarding: (1) The proper application of inferential reasoning in competition cases - inferences must be based on proven primary facts and follow established evidential principles; the "best possible explanation" standard cannot override direct evidence or excuse lack of proof of primary facts; (2) The requirement for proper characterization analysis in all section 4 cases, even per se prohibitions, to distinguish between horizontal and vertical relationships and ensure conduct truly falls within the object of the prohibition; (3) Recognition that manufacturer-distributor communications, even concerning pricing, do not automatically constitute horizontal collusion and must be analyzed in their proper commercial context; (4) The Competition Commission's burden to present a coherent case based on pleadings and cannot rely on the Tribunal to cure deficiencies in evidence or expand the case beyond what was pleaded; (5) The need for economic expert evidence when relying on pricing patterns as circumstantial evidence of collusion; (6) Constitutional requirements of fair hearing and legality apply to Competition Tribunal proceedings, requiring rigorous analysis and reasoned consideration of all evidence, including exculpatory evidence; (7) That per se prohibitions still require proper proof of the elements of the offense and cannot be established through speculation or conjecture. The judgment provides significant protection for legitimate commercial relationships and emphasizes evidential rigor in competition enforcement.
