In October 2006, Dawn Consolidated Holdings acquired DPI Plastics, a PVC pipe manufacturer with limited HDPE pipe manufacturing capacity. Dawn decided to mothball DPI's inefficient HDPE extruders and instead partnered with the Warplas Share Trust (WST). In April 2007, Dawn acquired a 49% stake in Sangio Pipe (Pty) Ltd, a newly formed company that acquired WST's HDPE pipe manufacturing business. The shareholders agreement included clause 20, a non-compete provision preventing Dawn and its subsidiaries from manufacturing HDPE pipes in South Africa for as long as Dawn held shares in Sangio, and requiring Dawn to procure all HDPE piping requirements from Sangio. In January 2014, Dawn notified the Commission of a merger to acquire sole control of Sangio. During this merger review, the Commission discovered clause 20 and initiated a complaint proceeding, alleging the clause violated section 4(1)(b)(ii) of the Competition Act (market division). The Tribunal found in favor of the Commission, holding that clause 20 constituted an impermissible restrictive horizontal practice.
