Bankruptcy Rules

Where an order has been made for the payment by a bankrupt, or by his employer for
            the time being, of a portion of his income or salary (including any bonus or commission
            payable to him), the bankrupt may, upon his ceasing to receive a salary or income of the
            amount he received when the order was made, apply to the court to rescind the order or
            to reduce the amount ordered to be paid by him to the trustee. And in the case of any
            increase in the amount of such salary, or income (inclusive of any bonus or commission
            as aforesaid) the
trustee may in like manner apply to
            the court to increase the amount ordered to be paid by the bankrupt to the
            trustee.
