Tax evasion prosecutions need proof of foundational records and individual partner responsibility before criminal liability can stand.

Convictions for tax evasion offences under the Income-tax Act require proof of the foundational documents and positive evidence of wilful concealment; an assessment based only on estimate or guesswork is insufficient where the seized notebooks and loose papers are not produced or proved. Vicarious criminal liability cannot be fastened on all partners of a firm unless the record shows that each was in charge of and responsible for the conduct of the business. On the stated facts, both the conviction and the prosecution of all partners were found unsustainable for want of adequate proof.

Issues: (i) Whether the conviction for offences under sections 276C, 277 and 278B of the Income-tax Act, 1961 could be sustained when the prosecution did not produce the seized notebooks and loose papers forming the basis of the allegation; (ii) Whether all partners of the firm could be prosecuted and held liable when the record did not show that each of them was in charge of and responsible for the conduct of the business.

Issue (i): Whether the conviction for offences under sections 276C, 277 and 278B of the Income-tax Act, 1961 could be sustained when the prosecution did not produce the seized notebooks and loose papers forming the basis of the allegation;

Analysis: The prosecution case rested on the assessment made by the Income-tax Officer, but the seized notebooks and loose papers said to be the foundation of the alleged concealment were not produced or proved. Those documents were primary documentary evidence, and in their absence the officer's statement and the assessment based on estimate and guesswork could not establish wilful attempt to evade tax or knowingly filing a false return. Criminal liability required positive material and proof beyond reasonable doubt, not merely an adverse assessment finding.

Conclusion: The conviction on this ground was unsustainable and was set aside in favour of the assessee.

Issue (ii): Whether all partners of the firm could be prosecuted and held liable when the record did not show that each of them was in charge of and responsible for the conduct of the business.

Analysis: The material did not establish that every partner was responsible for the conduct of the business. The return and verification were signed by one partner, and there was no clear allegation or proof that all partners were in charge of and responsible for the firm's affairs. Vicarious liability under the penal provision could not be fastened on all partners merely by naming them in the prosecution papers.

Conclusion: The prosecution of all partners was not legally sustainable and was set aside in favour of the assessee.

Final Conclusion: The criminal revision succeeded because the conviction was based on inadequate proof and the liability of all partners was not properly established.

Ratio Decidendi: A conviction for tax evasion offences cannot rest solely on an unproved assessment founded on estimate or guesswork; the prosecution must prove the foundational documents and establish, by positive evidence, wilful concealment and the individual responsibility of any partner sought to be made liable.
