Issues: (i) Whether additions based mainly on electronic material retrieved from seized mobile devices could be sustained in the absence of reliable proof of authenticity, continuity of custody, and proper compliance with the prescribed digital-evidence procedure; (ii) Whether approvals granted under section 153D were vitiated for want of independent application of mind to the draft assessments and the material relied upon.
Issue (i): Whether additions based mainly on electronic material retrieved from seized mobile devices could be sustained in the absence of reliable proof of authenticity, continuity of custody, and proper compliance with the prescribed digital-evidence procedure.
Analysis: The additions rested substantially on screenshots, WhatsApp chats, and images said to have been extracted from mobile devices and linked to alleged unaccounted transactions. The record did not establish a complete and reliable chain of custody from seizure to extraction and use in assessment, and the material placed before the Tribunal did not satisfactorily show how the working copies were handled or how the relied-upon outputs were produced for assessment purposes. The Tribunal also found that the electronic material was secondary in nature and lacked adequate corroboration from independent books, documents, or other physical evidence. In these circumstances, the Tribunal held that the digital material did not possess sufficient evidentiary credibility to sustain the disputed additions.
Conclusion: The issue was decided in favour of the assessee and against the Revenue.
Issue (ii): Whether approvals granted under section 153D were vitiated for want of independent application of mind to the draft assessments and the material relied upon.
Analysis: The approval was examined in the context of long, electronically driven search assessments involving multiple years and substantial additions. The approval letters did not show any real engagement with the specific issues, the digital-evidence concerns, or the manner in which the Assessing Officer had used the material. The Tribunal held that section 153D requires a meaningful prior approval for each assessment year, and that a bare or ritualistic sanction does not satisfy the statutory requirement. Since the approval reflected no discernible application of mind to the critical aspects of the draft assessments, it was held to be mechanical and invalid.
Conclusion: The issue was decided in favour of the assessee and against the Revenue.
Final Conclusion: The assessments could not survive because the core additions were founded on unreliable electronic material and the statutory prior approval was vitiated. The assessee's appeals succeeded and the Revenue's appeals failed, with the impugned assessments set aside.
Ratio Decidendi: Where search assessments rest principally on digital material, the Revenue must establish authenticity, continuity of custody, and reliable admissibility of the electronic evidence, and prior approval under section 153D must reflect independent application of mind to the draft order and the material on record.
Digital evidence integrity and meaningful prior approval determine validity of search assessments founded on seized mobile-device material.
Electronic material retrieved from seized mobile devices cannot sustain search-assessment additions without reliable proof of authenticity, continuity of custody, compliant extraction and production procedures, and adequate independent corroboration. Screenshots, WhatsApp chats and images treated as secondary evidence lacked sufficient evidentiary credibility where the handling of working copies and relied-upon outputs was not established; the additions were therefore unsustainable. Prior approval under section 153D must involve meaningful, year-specific consideration of draft assessments and the material relied on. Bare approval letters showing no engagement with critical digital-evidence issues constitute mechanical sanction and are invalid. The assessments were set aside, with the assessee's appeals succeeding and the Revenue's appeals failing.
Admissibility of electronic evidence - Substantial compliance with digital evidence protocol - reliability on electronic evidence in the form of vague SMS/WhatsApp messages or images of Sambhav Software - Approval under section 153D - Mechanical approval Admissibility of electronic evidence - Secondary electronic record - Chain of custody - Section 65B compliance - additions based substantially on electronic material extracted from seized devices - only evidence is images of ‘Sambhav software’ - HELD THAT: - The Tribunal held that, although strict rules of the Evidence Act may not in terms govern income-tax assessments, the fundamental principles concerning relevancy, admissibility, probative value, and fairness do apply to quasi-judicial proceedings. Where additions are based exclusively on electronic material, the Revenue must establish the genuineness and integrity of that material. The Board's Digital Evidence Investigation Manual was treated as embodying the required procedure at least in substance. On the record produced, the Panchnama did not record the hash values or complete device particulars; the certificates obtained at the time of backup only certified the cloning process and not the later extraction and use of the alleged incriminating material; and the chain of custody was not maintained beyond the initial handover. The extracted images and chats were therefore left unsupported as reliable electronic evidence, particularly when they were themselves secondary material and were not corroborated by any independent books, documents, or business discrepancies. On that basis, the electronic material relied upon by the Assessing Officer was held inadmissible for drawing the disputed conclusions. [Paras 37, 38, 39, 40, 41] The assessee's challenge to the assessments on the ground that they were framed on inadmissible electronic material was sustained. Approval under section 153D - Application of mind or Mechanical approval - HELD THAT: - The Tribunal held that approval under section 153D is not an empty administrative ritual but a statutory safeguard requiring conscious examination of the draft assessment for each assessment year. In the present case, the draft orders were extensive, the issues varied across years, and the entire case depended on electronic material whose admissibility itself required scrutiny. Yet the approval letters merely recorded grant of approval on the same date and did not show that the approving authority had examined whether the mandatory procedural safeguards regarding the electronic evidence and the Board's prescribed protocol had been followed. The subsequent relief granted by the first appellate authority on the Assessing Officer's own treatment of receipts and payments further demonstrated absence of proper scrutiny at the approval stage. The Tribunal therefore found the approval to be mechanical and the assessments vitiated on that ground as well. [Paras 48, 49, 50, 51, 52] The challenge to the validity of the section 153D approval was upheld, and the assessments were held vitiated. Final Conclusion: The Tribunal held that the impugned search assessments were founded on inadmissible electronic material and were also vitiated by mechanical approval under section 153D. The assessee's appeals were allowed, the Revenue's appeals were dismissed, and the assessments were quashed.
