consideration from the respondents within 15 days of the confirmation of the sale 12and whatever pleas have been taken by the appellant-Bank to avoid acceptance are all subsequent and are not very material. 19. In these facts and circumstances, reason for the non- issuance of the sale certificate is solely attributable to the appellant-Bank and that there were no latches, negligence or default on part of the respondents in offering to deposit the balance auction amount. Since there is no default on their part, non-deposit of the said amount within the stipulated period would not be fatal within the meaning of sub-Rules (4) and (5) of Rule 9 of the Rules. 20. It is pertinent to mention here that the cancellation of the auction sale vide communication dated 24.12.2019 is purely unilateral in nature without any notice or opportunity of hearing to the respondents. The said cancellation as such is per se in violation of the principles of natural justice and is illegal. 21. Learned counsel
