SST Consulting Services Pty Ltd v Rieson

SST Consulting Services Pty Ltd (the appellant) sought to enforce a guarantee against Stephen Rieson and Scott Bell (the respondents) concerning a loan made to AFS Freight Management (USA) Inc. The respondents sought to avoid enforcement, arguing the underlying contract was void and unenforceable due to illegality, specifically a breach of section 47(1) of the Trade Practices Act 1974 (Cth) ("TPA") for engaging in exclusive dealing. The High Court of Australia considered whether the contract was void or unenforceable, and the relevance of other relief available under the TPA, including the application of section 4L concerning severance.

The central legal issues before the High Court were whether the loan agreement, which obliged the borrower to acquire services from third parties specified by the lender, constituted exclusive dealing in breach of section 47(1) of the TPA. The Court also had to determine whether such a breach rendered the entire contract void or unenforceable for illegality, and if so, whether section 4L of the TPA permitted or mandated the severance of the offending provision. The Court was asked to consider the nature and application of severance, particularly whether section 4L engaged common law rules of severance or established its own framework, and the relevance of the TPA's objects and legislative history to this interpretation.

The High Court reasoned that the arrangement, whereby the appellant lent money to AFS USA and the respondents guaranteed repayment along with "certainty in relation to the work" for a company in which the appellant's directors had an interest, constituted exclusive dealing prohibited by section 47 of the TPA. The Court found that section 4L of the TPA was not a general code for common law severance but a specific provision applicable to particular contracts within the context of restrictive trade practices, designed to impose sanctions on such practices. The Court concluded that the appeal should be allowed, setting aside the orders of the Full Court of the Federal Court and dismissing the appeal to that Court with costs.
