Issue-estoppel in criminal law bars relitigation of a fact earlier decided in favour of the accused, defeating later forgery convictions.

A prior acquittal on a specific factual issue can operate as issue-estoppel in later criminal proceedings between the same parties, preventing the prosecution from re-agitating that fact even where the subsequent charge is for a different offence. Section 403 of the Code of Criminal Procedure, 1898 embodies autrefois acquit but does not exhaust the field or exclude issue-estoppel, and Section 26 of the General Clauses Act, 1897 does not defeat the principle. Where the later prosecution for forgery depended entirely on a fact already decided in the accused's favour, the foundation of the prosecution failed and the convictions under the Indian Penal Code could not stand.

Issues: Whether an earlier acquittal on a factual issue operated as issue-estoppel in a later prosecution so as to bar the appellants' convictions for forgery and use of forged documents, and whether Section 403 of the Code of Criminal Procedure, 1898 excluded that rule.

Analysis: A prior acquittal by a competent court on a lawful charge and after a lawful trial is not confined to barring a second trial for the same offence; where the same fact has been distinctly determined in favour of the accused, the finding may operate as an estoppel against the prosecution in subsequent proceedings between the same parties. Section 403 of the Code of Criminal Procedure, 1898 embodies the rule of autrefois acquit, but it does not exhaust the whole field so as to exclude issue-estoppel. Section 26 of the General Clauses Act, 1897 likewise does not prevent the application of this principle. Since the prosecution for forgery depended entirely on the allegation already negatived in the earlier criminal case, the foundation of the later charges failed.

Conclusion: The rule of issue-estoppel applied, the prosecution was precluded from disputing the earlier finding of fact, and the convictions under Sections 467 and 471 of the Indian Penal Code, 1860 could not stand.

Ratio Decidendi: Where a competent criminal court has finally determined a specific issue of fact in favour of an accused, the prosecution in a later proceeding between the same parties cannot adduce evidence inconsistent with that finding, even though the later charge is for a different offence and is not barred by Section 403 of the Code of Criminal Procedure, 1898.
