A Regular Bail Application is filed when a person is already arrested and kept in judicial custody, seeking release from jail during investigation or trial. It is presented before the magistrate or sessions court depending on the seriousness of the offence.

The court examines factors like the nature of the offence, evidence, criminal background of the accused, and chances of absconding or influencing witnesses. The main focus is whether continued custody is necessary for a fair investigation.

The defence argues that the accused should not be kept in jail unnecessarily since they are presumed innocent until proven guilty. The prosecution may oppose bail by highlighting seriousness of the case or risk to investigation.
