- Summary- Companies- Consumer rights advocate bringing case for customers- Amazon says collective action is 'without merit'- Case focuses on marketplace's 'Buy Box' featureLONDON, Oct 20 (Reuters) - Amazon.com Inc (AMZN.O) is facing a lawsuit in Britain for damages of up to 900 million pounds ($1 billion) over allegations the online marketplace abused its dominant position by favouring its own products, lawyers said.Hunter said in a statement: “Far from being a recommendation based on price or quality, the Buy Box favours products sold by Amazon itself, or by retailers who pay Amazon for handling their logistics.Other sellers, however good their offers might be, are effectively shut out.”An Amazon spokesperson said in a statement: “This claim is without merit and we’re confident that will become clear through the legal process.”The lawsuit is expected to be filed at the CAT by the end of this month and will have to be certified by the tribunal before it can proceed.The case follows the announcement by Britain’s antitrust watchdog in July that it is investigating Amazon over suspected breaches of competition law, including how it selects which products are placed within the “Buy Box” feature.Amazon has faced similar probes elsewhere, recently making an offer to the European Commission to avert possible hefty EU antitrust fines."
