“9. It is axiomatic that condonation of delay is a matter of discretion of the Court. Section 5 of the Limitation Act does not say that such discretion can be exercised only if the delay is within a certain limit. Length of delay is no matter, acceptability of the explanation is the only criterion. Sometimes delay of the shortest range may be condonbale due to want of acceptable explanation whereas in certain other case, delay of a very long range can be condoned as the explanation thereof is satisfactory. Once the Court accepts the explanation as sufficient, it is the result of positive exercise of discretion and normally the superior Court should not disturb such finding, much less in revisional jurisdiction, unless the exercise of discretion was on wholly untenable grounds or arbitrary or perverse. But it is a different matter when the First Court refuses to condone the delay. In such cases, the superior Court would be free to consider the cause shown for the delay afresh and it is open to such superior Court to come to its own finding even untrammeled by the conclusion of the lower Court”.
