Presumption of culpable mental state under tax law requires proof of foundational facts before conviction can stand.

In a prosecution for abetment of filing a false return under the Income-tax Act, the prosecution must first prove the foundational facts of abetment beyond reasonable doubt before the statutory presumption of culpable mental state under Section 278E can operate. Reliance on an assessee's untested show-cause reply was insufficient where the maker was not examined and the reply was not subjected to cross-examination. The Court held that the prosecution, not the accused, bore the burden of establishing those basic facts, and the presumption of mens rea could not be used to sustain conviction on incomplete proof. The conviction and sentence were therefore set aside.

Issues: Whether the conviction for abetment of filing a false return under Section 278 of the Income-tax Act, 1961 could be sustained when the prosecution did not examine the assessee whose show-cause reply was relied upon, and whether the presumption under Section 278E of the Income-tax Act, 1961 could be invoked without proof of foundational facts.

Analysis: The prosecution case rested substantially on the show-cause reply of the assessee attributing responsibility to the petitioner. That reply was treated as the principal basis for inferring abetment, but the assessee was not examined as a witness, depriving the petitioner of the opportunity to test her version by cross-examination. The Court held that the credibility of the reply could not be presumed in the absence of such examination, and that the prosecution, not the accused, had the burden to establish the foundational facts necessary to prove abetment. Only after those facts are proved can the statutory presumption of culpable mental state under Section 278E operate. Since the foundational facts were not proved beyond reasonable doubt, the presumption of mens rea could not be used to sustain the conviction.

Conclusion: The conviction and sentence could not be sustained, and the finding of guilt under Section 278 of the Income-tax Act, 1961 was set aside.

Final Conclusion: The criminal revision succeeded, resulting in acquittal of the petitioner and discharge from bail bonds.

Ratio Decidendi: In a prosecution under Section 278 of the Income-tax Act, 1961, the statutory presumption of culpable mental state under Section 278E can arise only after the prosecution proves the foundational facts of abetment beyond reasonable doubt; reliance on an untested show-cause reply, without examining the maker, is insufficient to sustain conviction.
