Tribunal power to supervise and modify company compromises and order winding up if a scheme cannot be implemented. Section 231 authorises the tribunal to supervise implementation of a sanctioned compromise or arrangement and to give directions or make modifications for proper implementation; if the tribunal finds the scheme cannot be implemented satisfactorily and the company cannot pay its debts under the scheme, it may order winding up, and these powers apply, so far as practicable, to compromises or arrangements sanctioned before the Act commenced.
