A group of stockholders of Ontoit, Inc., brought suit, on behalf of themselves and the other stockholders of the corporations, and derivatively, on behalf of the corporations, against FirstCount, an accounting firm, and two of its employees to recover damages for breach of contract and fraud. The stockholders alleged that the defendants had failed to disclose in annual audits of the corporations' books that certain commissions were being improperly paid to, and by, three of the corporation's principal officers and directors. As a result, the corporations had been deprived of the use of large sums of money over an approximate ten-year period. While the action was pending, the plaintiff stockholders all sold their stock back to the corporations. The defendants argued that the stockholders lacked standing to sue the corporations either on their own behalf or on behalf of the corporations. What should the court decide, and why?
