Article 468

No holder of a decree in execution of which property is sold shall, without the written permission of the court, a copy of which shall be given by the court to the auctioneer, bid for or purchase the property.

Where a decree-holder purchases with such permission, the purchase-money and the amount due on the decree, may, on such terms as shall be prescribed, be set off against one other, and the court executing the decree shall enter up satisfaction of the decree in whole or in part accordingly.

Where a decree-holder purchases, by himself or through another person, without such permission, the court may on the application of the judgment-debtor or any other person whose interest are affected, set aside the sale.
