"The main reason why an assignee of a part of a debt is required to join all parties interested in the debt in an action to recover the part assigned to him is in my opinion because the Court cannot adjudicate completely and finally without having such parties before it. The absence of such parties might result in the debtor being subjected to future actions in respect of the same debt, and moreover might result in conflicting decisions being arrived at concerning such debt. In my opinion, however, this reasoning does not apply to a winding up petition. After a winding up order has been made the Court in all cases when it is necessary will investigate, adjudicate upon, and settle the petitioner's debt as well as the debts of the other creditors. In the case of an assignee of part of a debt the Court in adjudicating upon his claim can and will do so in the presence of the persons entitled to the remainder of the debt, and the rights of all parties interested in the debt will be completely and finally settled once and for all."
