“However, I do not see why that should mean that where a matter concerning the company is before the court and the court is quite satisfied that there is jurisdiction to make a winding up order because one or more of the circumstances in section 122(1) apply, the court is in every case powerless to act simply because nobody has petitioned for the winding up under section 124(1). I do not see why in the case of a registered company the court should not in an appropriate case of its own motion decide on the facts before it that it has power to make a winding up order under section 122(1) and that it should make such an order.”
