Issue estoppel in criminal law did not bar prosecution after a preventive Section 107 inquiry ended without conviction or acquittal.

Issue estoppel in criminal law applies only when a prior criminal trial between the same parties has finally determined an issue of fact or law and the later prosecution would contradict that determination. A preventive inquiry under Section 107 of the Code of Criminal Procedure, 1898 is not a criminal trial for an offence and, where it ends without conviction or acquittal, does not create a conclusive bar. Rejection of evidence in such an inquiry therefore does not prevent the State from proving the same incident in a later prosecution under Sections 323 and 324 of the Indian Penal Code, 1860. The prosecution was maintainable and the appeal succeeded.

Issues: Whether the principle of issue estoppel barred the criminal prosecution for offences under Sections 323 and 324 of the Indian Penal Code, 1860 on the basis of an earlier proceeding under Section 107 of the Code of Criminal Procedure, 1898 in which evidence relating to the same incident had been found insufficient.

Analysis: Section 403 of the Code of Criminal Procedure, 1898 embodies the pleas of autre fois acquit and autre fois convict, while issue estoppel operates only where a prior criminal trial between the same parties has finally determined an issue of fact or law and the later prosecution necessarily seeks to contradict that determination. The earlier proceeding under Section 107 was not a criminal trial of the respondents for any offence, and it resulted in no conviction or acquittal. It was only a preventive binding-over inquiry to decide whether there was apprehension of breach of peace. Rejection of evidence in that proceeding did not amount to a conclusive finding that could prevent the State from proving the same incident in a subsequent prosecution for substantive offences.

Conclusion: The bar of issue estoppel did not apply, and the prosecution and conviction for the substantive offences were maintainable. The appeal succeeded.

Ratio Decidendi: Issue estoppel in criminal law applies only when a prior criminal trial has finally determined an issue between the State and the accused; it does not arise from a preventive inquiry under Section 107 of the Code of Criminal Procedure, 1898 that ended without conviction or acquittal.
