The Competition Commission received a complaint in December 2003 from Nutri-Flo CC and Nutri-Fertilizer CC alleging prohibited practices in the fertiliser market. Although the prescribed complaint form named SASOL Chemical Industries as the respondent, an accompanying affidavit alleged cartel conduct involving SASOL, Yara South Africa (formerly Kynoch Fertilizer) and Omnia Fertilizer. The Commission investigated and referred a complaint to the Competition Tribunal against all three firms. After SASOL settled with the Commission and admitted to collusive conduct, the Commission sought to amend its referral to include detailed allegations of collusion against Yara and Omnia, relying partly on information obtained from SASOL. Yara and Omnia opposed the amendment, arguing it fell outside the scope of the original Nutri-Flo complaint. The Tribunal granted the amendment and dismissed Omnia’s counter-application to set aside the referral. On appeal, the Competition Appeal Court (CAC) set aside the Tribunal’s decisions, holding that the original complaint was against SASOL only and could not be amended to introduce a new complaint or new respondents. The Commission then sought leave to appeal directly to the Constitutional Court, together with condonation for late filing.
