Excellent judgment which is well supported and reasoned from hon’ble High Court of Madras regarding issuance and recall of NBW non-bailable warrants.

It is further seen that the cases in which trial courts issue Non Bailable Warrants may be broadly classified in four categories namely, (i) the trial court issues Non Bailable Warrants without issuing summons first, (ii) the trial court issues a Non Bailable Warrant when the accused is absent for one or two hearings without inquiring into the cause of absence, (iii) where the accused is absent for one or two hearings and files a petition under Section 317 of the Code, the Court rejects the petition and issues a Non Bailable Warrant and (iv) where the accused has intentionally absented himself from the trial and does not attend any hearings and then, the trial court issues a Non Bailable Warrant.

From Para 18, 19 and 20,

It is also brought to my notice that apart from various other reasons for the long pendency of cases before the trial Courts, the non execution of Non Bailable Warrant is one among the reasons. This fact is reiterated through the last data collected by the NCRB.
In most of these pending cases, it is seen that whenever a Non Bailable warrant is kept pending execution, the usual practice among many of the Court is to adjourn the case on the ground that “Non Bailable Warrant is pending”. In heinous crimes, where there is deliberate and continuous non appearance of the accused, the trial Court may proclaim him as person absconding under Section 82 of the Code of Criminal Procedure. Thus, under Section 82 of Cr.P.C., there can be no impediment on the part of the trial Court to pronounce him as a proclaimed offender, instead of keeping the matter pending indefinitely for the purpose of having the warrant executed. Hence, the existence of the fourth category of cases cannot be a ground to preclude the High Court to do justice in the first three categories particularly, when they constitute a major portion of the pending cases in the State of Tamil Nadu, in which, Non Bailable Warrants are pending execution.
