What are the legal standards governing a national class action?

The legal standards governing national class actions in state courts are not clearly established. (See Anthony v. General Motors Corp. (1973) 33 Cal.App.3d 699, 708, 109 Cal.Rptr. 254.) There may be many possible combinations of facts involving nonresidents which might come under the rubric "national class action." Because of the lack of certainty in the law on the subject of national class actions, the determination of the validity of any such class action should await a more specific presentation of the facts after all relevant discovery on the point has been completed.
