Incomplete investigation prevents valid challan and charge when essential forensic report is still awaited

Regular bail under Section 439 CrPC was granted where the challan and framing of charge occurred before receipt of the Chemical Examiner's report. The Court examined Section 173 CrPC and stated that a police report is maintainable only after completion of investigation. It treated the absence of a material forensic report, needed to determine the nature of the recovered substance, as making the investigation incomplete. On that basis, the challan was incomplete, cognizance should not have been taken, and charge should not have been framed until the report was received.

Issues: Whether regular bail could be granted where the challan was filed and charge was framed before receipt of the Chemical Examiner's report, rendering the investigation incomplete.

Analysis: The petition was under Section 439 of the Code of Criminal Procedure, 1973. The Court examined the scheme of Section 173 of the Code and held that a police report is to be submitted only on completion of investigation. It further held that where a material forensic or chemical report necessary to determine the nature of the recovered substance has not been received, the investigation cannot be treated as complete. In such circumstances, the challan is incomplete, cognizance ought not to be taken on that basis, and charge should not be framed until the requisite report is received.

Conclusion: Bail was granted to the petitioner because the challan and charge were founded on an incomplete investigation without the Chemical Examiner's report.
