In April at Search Engine Land I reported Google agreed to settle on an AdWords case for $20 million. The case was over the daily budget feature and how many advertisers may have exceeded that budget by 120% on occasions.
Google said then, "Google believes the claims are without merit, but we are pleased to have the litigation behind us and to move forward with our business objectives."
I have a copy of the settlement as a PDF document for those interested in the extreme legal details.
