Once a judicial sale in execution has been confirmed by the Sheriff and transfer of title has been effected to a purchaser, the sale can only be set aside under common law on grounds of bad faith, fraud, or the purchaser's knowledge of prior irregularities in the sale. Technical or procedural irregularities in the execution process, even if established, are insufficient to justify setting aside a confirmed sale where title has passed to a bona fide purchaser for value. An innocent purchaser's rights are protected by law and cannot be easily impugned. The test for bias requires reasonable evidence of a real likelihood of operative prejudice, not mere suspicion. A judgment debtor who is aware of an impending sale but fails to timeously challenge it before confirmation and transfer cannot later rely on procedural irregularities to set aside the completed transaction. Courts must balance the interests of all parties and will consider the passage of time, the status of the purchaser, and whether subsequent events (such as further transfers) have occurred.
