22. Rescission and variation of order

On the application of any person receiving or ordered to pay a monthly allowance under this Part and on proof of a change in the circumstances of that person, his wife or child, or for other good cause being shown to the satisfaction of the court, the court by which the order was made may rescind the order or may vary it as it thinks fit.

Without prejudice to the extent of the discretion conferred upon the court by subsection (1), the court may, in considering any application made under this section, take into consideration any change in the general cost of living which may have occurred between the date of the making of the order sought to be varied and the date of the hearing of the application.
