“The old rule in the Court of Chancery was very simple and perfectly well understood. Under the old practice the Court required the presence of all parties interested in the matter in suit, in order that a final end might be made of the controversy. But when the parties were so numerous that you never could ‘come at justice’, to use an expression in one of the older cases, if everybody interested was made a party, the rule was not allowed to stand in the way. It was originally a rule of convenience: for the sake of convenience it was relaxed. Given a common interest and a common grievance, a representative suit was in order if the relief sought was in its nature beneficial to all whom the plaintiff proposed to represent.”
“should not be encouraged to regard himself as a mere cypher, lending his name to the application for formal purposes but devoid of all responsibilities”
