Rejection of books and estimate-based additions need specific defects, while penalty requires proof of deliberate concealment.

Books of account cannot be rejected under section 145(2) merely on suspicion, comparative cost concerns, or doubts about contractor arrangements unless specific defects, omissions, or unreliability are shown. Estimated additions based on wrongly discarded books and surmise are not legally sustainable without a lawful basis and material nexus. A finding that contractors were benamidars requires proof from the Department, and disbelief alone is insufficient. Penalty under section 271(1)(c) requires positive material of deliberate concealment or inaccurate particulars; an estimate-based addition by itself does not attract penalty.

Issues: (i) whether the Tribunal was justified in applying section 145(2) and rejecting the assessee's accounts; (ii) whether the additions sustained on estimate were legally supportable; (iii) whether the raising contracts could be treated as lacking credibility or as benami arrangements; and (iv) whether penalty under section 271(1)(c) was attracted.

Issue (i): whether the Tribunal was justified in applying section 145(2) and rejecting the assessee's accounts.

Analysis: The accounts were not shown to suffer from any specific defect, omission, or irregularity. Mere suspicion about the arrangements with contractors or a higher cost of raising ore, without cogent material showing incompleteness or unreliability of the accounts, was insufficient to justify rejection of the books and invocation of the best judgment route.

Conclusion: The Tribunal was not justified in applying section 145(2) against the assessee.

Issue (ii): whether the additions sustained on estimate were legally supportable.

Analysis: The additions rested on surmise and estimate after the books were wrongly rejected. In the absence of a lawful basis for discarding the accounts and without a reasonable nexus to material on record, the estimated additions could not stand.

Conclusion: The estimated additions were not sustainable and were against the assessee.

Issue (iii): whether the raising contracts could be treated as lacking credibility or as benami arrangements.

Analysis: Though the authorities doubted the genuineness of the contracts, no material was brought to establish that the contractors were benamidars of the assessee. The burden to prove benami character lay on the Department and was not discharged.

Conclusion: The finding that the contractors were benamidars was not sustainable, but the mere disbelief in the contracts was not supported by material.

Issue (iv): whether penalty under section 271(1)(c) was attracted.

Analysis: Penalty proceedings are penal in nature and require proof of deliberate concealment or furnishing of inaccurate particulars. An addition made on estimate, without cogent material showing conscious concealment, could not by itself justify penalty.

Conclusion: Section 271(1)(c) was not attracted and the cancellation of penalty was justified.

Final Conclusion: The reference was answered in favour of the assessee; the assessments could not be sustained on the basis adopted by the revenue authorities, while the deletion of penalty was upheld.

Ratio Decidendi: Books of account cannot be rejected and income cannot be enhanced on best judgment merely on suspicion or comparative estimates without specific defects in the accounts, and penalty under section 271(1)(c) requires positive material showing deliberate concealment.
