“8. Where a case is brought before the court beyond the period of limitation, the applicant has to explain to the court as to what was the sufficient cause, which means an adequate and enough reasons which prevented him to approach the court within the period of limitation. Even after the “sufficient cause” is established, the court still has the discretion to decide whether to allow or dismiss the application for condonation of delay upon the bona fides of the party. Such discretion is not to be exercised by the court when the delay is caused by negligence, inaction or lack of bona fide. In such cases, even though the law of limitation harshly affects or causes inconvenience to the party, the court has to apply it with all its rigour. In order to advance substantial justice, though liberal and justice oriented approach or cause of substantial justice may be kept in mind but the same cannot be used to defeat the substantial law of limitation.”
