Tax prosecution cannot survive when the assessment and penalty forming its basis are set aside on appeal.

Criminal prosecution for alleged concealment of income and filing of a false return lost its foundation after the appellate authority set aside the assessment and penalty on which it was based. Where the tax findings giving rise to the complaint no longer survived, continuation of the prosecution would amount to misuse of the process of court and serve no useful purpose. The prosecution was therefore unsustainable once the underlying income-tax basis had been annulled in appeal.

Issues: Whether the criminal prosecution for alleged concealment of income and false return could be quashed when the Commissioner of Income-tax had allowed the assessee's appeal and set aside the assessment and penalty forming the basis of the prosecution.

Analysis: The prosecution rested on the allegation that the petitioners had concealed income and were liable to penalty under the income-tax proceedings. The appellate authority, however, had accepted the assessee's challenge and set aside the assessment and penalty. Once the very foundation of the complaint no longer survived, continuing the prosecution would serve no useful purpose and would amount to misuse of the process of court. The existence of an alternative plea before the trial court did not alter the fact that the prosecution had lost its substratum.

Conclusion: The criminal prosecution was unsustainable and liable to be quashed in favour of the petitioners.

Ratio Decidendi: Where the assessment and penalty forming the foundation of a tax prosecution are set aside in appeal, the prosecution based solely on those findings cannot be sustained.
