The digital colossus Amazon faces a fresh legal challenge as the Australian Competition and Consumer Commission (ACCC) files a lawsuit alleging the tech giant imposed unfair contract terms on third-party sellers. The case, which centres on clauses that reportedly stripped sellers of their legal rights and gave Amazon unilateral control over payments and dispute resolution, has now caught the attention of British regulators, who are closely monitoring the proceedings.
The ACCC’s action, announced earlier this week, targets Amazon’s standardised agreements with marketplace merchants. These contracts, the regulator argues, contained terms that were inherently one-sided, such as the ability to terminate agreements without cause, mandatory arbitration in Luxembourg despite most sellers being based in Australia, and indemnity clauses that left sellers liable for Amazon’s own negligence. The lawsuit seeks penalties and an injunction to prevent Amazon from enforcing these provisions.
This is not the first time Amazon has faced scrutiny over its contractual practices. The European Union and the United Kingdom have both launched investigations into the company’s treatment of third-party sellers, with the UK’s Competition and Markets Authority (CMA) now reportedly briefed on the Australian case. The CMA has been increasingly active in regulating Big Tech, having recently introduced new powers to fine companies for breaching consumer protection laws. A spokesperson for the CMA told the Financial Times that the authority is reviewing the details of the Australian action and will consider whether similar issues exist in British contracts.
The Australian case highlights a broader concern: the imbalance of power in platform-mediated markets. Amazon operates a two-sided marketplace where it both owns the platform and competes with sellers. This dual role has long raised eyebrows among competition watchdogs. The ACCC’s lawsuit zeroes in on the fine print, arguing that Amazon’s standard contract terms amount to unfair practices under Australian consumer law, which defines unfair terms as those that create a significant imbalance in the parties’ rights and are not reasonably necessary to protect the business’s legitimate interests.
For the average seller, these terms translate into a precarious existence. One misstep, or a change in Amazon’s algorithm, can mean removal from the platform without recourse. The ‘user experience’ of selling on Amazon is one of constant anxiety, and the legal framework tilts heavily in Amazon’s favour. The ACCC’s commissioner, Liza Carver, stated that the alleged conduct not only harms individual sellers but also reduces competition and innovation in the Australian market.
Amazon, for its part, has pushed back. In a statement, the company said it believes the terms are ‘fair and standard among similar marketplaces’ and that it has always acted in the best interests of customers and sellers. But this defence rings hollow for small business owners like Sarah Jenkins, a Melbourne-based toy seller who was banned from Amazon after her account was hacked and the company refused to review the decision. ‘I had no voice, no recourse,’ she told reporters. ‘Amazon holds all the cards.’
The tech sector is watching closely, as these cases could set a precedent for how platform economies are regulated. Silicon Valley has long operated on a ‘move fast and break things’ ethos, but regulators are now breaking the mould. The British interest in the Australian case signals a coordinated, cross-border push to hold digital gatekeepers accountable. Julian Vane, a former Silicon Valley executive turned tech ethicist, notes that ‘the era of unfettered algorithmic control is ending. Regulators are finally grasping that contracts are not just legal documents but instruments of power. The question is whether they will act to rebalance that power.’
As the Australian court prepares to hear the case, the CMA’s involvement suggests a tightening of legal nets around Amazon’s business model. The outcome could reshape the very structure of online marketplaces, forcing platforms to rewrite their contracts and rethink their relationship with the merchants who fuel their growth. For now, the digital watchdogs are barking, but whether they will bite remains to be seen.
