 Judge Weber noted that three of the four requirements for a class action suit were met (commonality [there are questions of law or fact common to the class], numerosity [the class is so large that individual suits are impractical], and typicality [claims of each class member are typical of the claims of the class]).However, class action status was not granted because the judge was unable to determine whether Mayo would adequately represent the class (the adequacy element).Finally, the judge noted that Mayo had failed to provide directions to the United States Marshals Service as to service of process.
