(1) If the arrear cannot be recovered by any of the processes hereinbefore provided, or if the Financial Commissioner considers the enforcement of any of those processes to be inexpedient, the Collector may, where the defaulter owns any other estate or holding, or any other immovable property, proceed under the provisions of this Act against that property as if it were the land in respect of which the arrear is due:
    Provided that no interest save those of the defaulter alone shall be so proceeded against, and no incumbrances created, grants made or contracts entered into by him in good faith shall be rendered invalid by reason only of his interests being proceeded against.
    (2) When the Collector determines to proceed under this section against immovable property other than the land in respect of which the arrear is due, he shall issue a proclamation prohibiting the transfer or charging of the property.
    (3) The Collector may at any time by order in writing withdraw the proclamation, and it shall be deemed to be withdrawn when either the arrear has been paid or the interests of the defaulter in the property have been sold for the recovery of the arrear.
    (4) Any private alienation of the property, or of any interest of the defaulter therein, whether by sale, gift, mortgage or otherwise, made after the issue of the proclamation and before the withdrawal thereof shall be void.
    (5) In proceedings against property under this section the Collector shall follow, as nearly as the nature of the property will admit, the procedure prescribed for the enforcement of process against land on which an arrear of land-revenue is due.
