The decision concerned arbitrations, not suits, but that's no problem. Companies now use their standard contract to use arbitration to settle disputes. This is bad because you can't appeal the findings of a private arbitration hearing, nor is there an independent or public means of reviewing an arbitrator's decisions. They are designed to be conducted in private, unlike court cases.
The decision "basically lets companies escape class actions, so long as they do so by means of arbitration agreements," said Brian T. Fitzpatrick, a law professor at Vanderbilt University, in the New York Times.
Armed with this case, Microsoft has changed the terms of its consumer EULA. You know, that contract no one reads. Last Friday, right before Memorial Day when no one noticed it, Tim Fielden, assistant general counsel for Microsoft, announced that Microsoft was changing its EULA.
