Tax tribunal estimates of undisclosed income must rest on evidence and reasons, not conjecture or unsupported assumptions.

A quasi-judicial tax tribunal must base any estimate of undisclosed income on evidence, reasons and probabilities disclosed on the record; it cannot sustain a reduced addition on conjecture, surmises or an unsupported figure. Where the tribunal disbelieves the assessee's explanation but makes an arbitrary estimate without material basis, that finding is not justified in law and is liable to be rejected. The reference jurisdiction also required the matter to be reconsidered and disposed of afresh by the tribunal in accordance with law after hearing the parties.

Issues: Whether the Tribunal was justified in reducing the addition of Rs. 1,37,000 to Rs. 50,000 as income from undisclosed sources when its finding was unsupported by evidence and based on conjecture.

Analysis: The Tribunal had disbelieved the assessee's explanation for the cash credit, but it nevertheless reduced the addition to Rs. 50,000 without recording any material basis for that estimate. A quasi-judicial appellate authority must decide on the evidence and probabilities disclosed on the record, but it cannot rest its conclusion on surmises, speculation, or an arbitrary offer made by counsel. Since the reduction of the addition was made without reasons or supporting material, the finding could not be sustained. At the same time, the procedural consequence under the reference jurisdiction required the Tribunal to reconsider the appeal conformably with the High Court's answer and after hearing the parties.

Conclusion: The Tribunal's estimate of income at Rs. 50,000 was not justified in law and was liable to be rejected; the appeal of the assessee failed, though the Tribunal was directed to dispose of the matter afresh in accordance with law and after hearing the parties.

Final Conclusion: The legal principle affirmed is that an appellate tax finding must rest on reasons and evidence, not on conjecture, and a reference order may require fresh disposal by the Tribunal while leaving the revenue's addition undisturbed in the appeal before the Court.

Ratio Decidendi: A quasi-judicial tax tribunal cannot sustain an estimate of undisclosed income on conjectures, surmises, or unsupported assumptions; its finding must be grounded in material on record and supported by reasons.
