Legal action brought against Google for allegedly tracking the personal data of four million iPhone users can go ahead in the UK, three judges have ruled.
The case had previously been blocked by the High Court.
It was brought by Richard Lloyd, former director of the consumer rights group Which?
Google said in response: "The case relates to events that took place nearly a decade ago and that we addressed at the time."
"We believe it has no merit and should be dismissed," it added
Between 2011 and 2012, Google cookies - small computer text files - collected data on health, race, ethnicity, sexuality and finance, through Apple's Safari web browser, even when users had chosen a "Do not track" privacy setting, Mr Lloyd alleges.
