Prohibition on officer bidding bars officers involved in sale duties from acquiring interests in attached property. An officer or any person having duties connected with a sale under the Customs (Attachment of Property of Defaulters for Recovery of Government Dues) Rules, 1995 shall not, directly or indirectly, bid for, acquire or attempt to acquire any interest in the property sold, establishing a categorical prohibition tied to sale-related duties to protect the integrity of the recovery process.
