How to revoke nbw issued to accused for not attending date

It can be recalled by filing a petition in the court.

I have a peculiar strange notion about Non Bailable Warrant.

There're, of course, bailable and non-bailable offences.      There, I think, are, however, no bailable warrants.       Warrant is issued means the party must be arrested and produced before the court.     Police have no powers to grant bail.      Even if a warrant is issued, it can be recalled by the court at its discretion.      He needn't necessarily be given remand.      A magistrate has powers to issue warrant but, in regard to certain offences and in regard to gender of the party, has limitations to grant bail.
