A federal judge in San Jose, California has approved a settlement in a click-fraud class action lawsuit against Yahoo. The settlement requires Yahoo to pay $5 million in attorney fees and give full credits to advertisers dating back to 2004, CNET reports.

The claims in the lawsuit were raised by Checkmate Strategic Group, which argued that Yahoo charged advertisers for fraudulent clicks on online ads. The settlement is now final, after having been given preliminary approval by the court last summer.

The "final approval of the settlement validates the strength of Yahoo's click-through protection systems, and our commitment to delivering a quality experience to both our advertisers and our consumers," said Reggie Davis, Yahoo's new VP of marketplace quality.
