An interested party may apply to court to set aside a sale in execution before transfer on good cause shown at common law, independently of Rule 359(8). Rule 359(8), which provides a one-month time limit for applying to court to set aside the Sheriff's decision confirming or refusing to confirm a sale, applies only to challenges to that specific decision made under Rule 359(7). It does not apply to applications to set aside the sale based on grounds arising after the Sheriff's confirmation decision, such as unreasonable delay by the purchaser in paying the purchase price. The common law right exists in addition to the statutory right under Rule 359(8), and where an applicant is exercising the common law right rather than the statutory right, the time limit in Rule 359(8) does not apply and no condonation is required.
