At any time before a compensation order has been complied with or fully complied with, the magistrates' court for the time being having functions in relation to the enforcement of the order may, on the application of the person against whom it was made, discharge the order, or reduce the amount which remains to be paid, if it appears to the court—
(a)that the injury, loss or damage in respect of which the order was made has been held in civil proceedings to be less than it was taken to be for the purposes of the order; or
(b)in the case of an order in respect of the loss of any property, that the property has been recovered by the person in whose favour the order was made.
