In "Google Books Settlement, 2008-2011," James Grimmelmann analyzes the impact of recent rulings and case resolutions on the Google Book Settlement. The rulings and resolutions are the In re: Literary Works in Electronic Databases Copyright Litigation ruling, the National Music Publishers' Association's resolution of The Football Association Premier League Limited, et al. v. You Tube, Inc. lawsuit (consolidated into Viacom v. YouTube), and the Wal-Mart Stores, Inc. v. Dukes et al. ruling.
Here's an excerpt:
The road to class-wide settlement—even to a much more modest settlement that covers only scanning and searching—now appears to be barred. What is more, in light of the freelancers' case and the Supreme Court's recent Wal-Mart case, the road to class-wide litigation also looks to be extraordinarily difficult. Google will raise many of the same adequacy of representation arguments in its opposition to class certification. It might still be more feasible for a few copyright owners holding large number of copyrights to litigate on an individual basis—but the major publishers, who best fit that bill, have all more or less made their peace with Google through its Partner Program. The odds of the authors being able to see this one through to the end have just dropped precipitously. Google is holding all the cards now, and they're all full houses.
