US supreme court rejects Google appeal over legal action
The US supreme court has rejected an appeal from Google over a class action lawsuit filed by advertisers who claim the internet company displayed their ads on "low quality" web sites.
Justices let stand a lower court ruling that said the lawsuit representing hundreds of thousands of advertisers using Google's AdWords program could go forward.
Google argued that a federal appeals court in San Francisco should not have approved the class action because damages must be calculated individually for each company advertiser.
The appeals court rejected that argument and approved use of a formula that would calculate harm based on the average advertiser's experience.
Google runs the world's largest digital ad network by far.
It generated 67 billion US dollars (£46 billion) in revenue last year.
