In criminal cases, there is a concept of granting temporary bail to an accused.
The prisoner does not cease to be a social human being once he is sent to jail.
If there are some eventuality like death of some near relative, or some social event in family, etc, temporary bails are granted by courts.
Once he is on temporary bail, he has to report back in jail by certain date.
Sometimes, there are further developments or unavoidable circumstances, for which an accused may want Extension of this period.
Courts grants such extensions in exercise of their inherent powers, if they are satisfied about the requirements of such extension.
There are no hard and fast rules. Each case is decided as per its own merits.
