Arbitrary tax findings are invalid where an income addition rests on conjecture rather than material evidence.

An addition treating encashed high denomination notes as taxable income was held unsustainable where the Tribunal's estimate rested on no stated material or reasoning. The Court said a finding based on conjecture, suspicion, or arbitrary estimate is not a valid finding of fact, and interference is justified when the fact-finding authority acts without evidence or reaches a conclusion no reasonable judicial mind could accept. It also held that the assessee's explanation could not be rejected merely because daily cash details were not recorded or because the exact source of each note was not proved on the record.

Issues: Whether the addition of Rs. 10,000 out of the encashed high denomination notes was supported by material and could be treated as the assessee's taxable income.

Analysis: The assessee's explanation was that the notes formed part of a substantial cash balance maintained for financing business activities. The Court held that the Tribunal's estimate that 35 notes were from the cash balance and 10 notes were from an undisclosed source was unsupported by any stated material or reasoning. A finding based on conjecture, suspicion, or arbitrary estimate cannot be treated as a valid finding of fact. The Court also held that, on the facts, it was unreasonable to reject the explanation merely because daily cash details were not recorded or because the exact source of each note was not proved.

Conclusion: The addition of Rs. 10,000 was not supported by material and was not sustainable; the finding was held to be arbitrary and invalid, in favour of the assessee.

Final Conclusion: The reference was disposed of by holding that the impugned addition could not stand, while the other question was not pressed.

Ratio Decidendi: A tax finding is not a valid finding of fact if it rests on no material and is merely an arbitrary guess, conjecture, or surmise; interference is justified where the fact-finding authority acts without evidence or on a view that no reasonable judicial mind could adopt.
