This case is a strong warning for businesses that tender, subcontract or partner with competitors. The commercial setting was technical, but the core story is simple. Qteq wanted to protect its position in coal seam gas work. The Court found that it tried, through conversations, dinner meetings, emails and draft agreements, to get competitors or likely competitors to limit how they competed.
The case matters because the arrangements were attempts. The Court did not need a neat signed cartel contract before penalties were available. It looked at what was proposed, who was involved, what the tender context was, and whether the proposed arrangement would restrict competition. It also treated personal involvement seriously. Mr Ashton was penalised separately and was not allowed to use insurance to cover the penalty.
For small and medium businesses, the practical line is clear. Joint tendering, subcontracting and supplier discussions can be legitimate, but the purpose and wording must be clean. Do not ask a competitor not to bid, to bid for only a slice of the work, to stay out of a customer account, or to agree not to compete after receiving training or technical know-how. If a collaboration needs exclusivity, get advice before the conversation turns into a competition problem.
