Best judgment sales tax assessment: authority may rely on wider commercial records and third-party material after fair opportunity.

In a best judgment sales tax assessment, the assessing authority may examine relevant commercial records beyond the dealer's account books, including third-party material, where the return appears incorrect or incomplete. Natural justice is satisfied if the assessee is informed of the material relied on and given a fair opportunity to meet it; the officer need not disclose confidential sources or necessarily examine third parties or merchants. Procedure under rules 8 and 9 is substantially complied with when the dealer is called upon to produce accounts and explain discrepancies through meaningful notice and opportunity. On that basis, the turnover estimate was treated as valid and the assessments were upheld as lawful.

Issues: (i) Whether the assessing authority could call for records beyond the account books and rely on material obtained from third parties in rejecting the return and estimating turnover; (ii) whether the assessee was denied natural justice by non-disclosure of third-party material or by failure to examine the third parties and merchants; (iii) whether the assessment was vitiated for want of proper opportunity and non-compliance with the procedure under rules 8 and 9.

Issue (i): Whether the assessing authority could call for records beyond the account books and rely on material obtained from third parties in rejecting the return and estimating turnover.

Analysis: Section 9 of the Madras General Sales Tax Act required a dealer to submit correct and complete returns, and where the return appeared incorrect or incomplete, the assessing authority was bound to make a best judgment assessment after giving a reasonable opportunity to prove correctness. The assessment rules permitted scrutiny of the dealer's records and authorised the authority, on relevant material, to determine turnover to the best of its judgment. The Court held that the authority was not confined to bare account books and could ask for supporting commercial records such as contracts, pattis, vouchers, stock books and similar documents where those were relevant to the genuineness of the return. It further found that the third-party books and contract records on which the estimate rested were reliable and that the assessees had failed to produce their own supporting records despite repeated opportunities.

Conclusion: The assessing authority was entitled to rely on the wider set of commercial records and the third-party material, and the objection was rejected.

Issue (ii): Whether the assessee was denied natural justice by non-disclosure of third-party material or by failure to examine the third parties and merchants.

Analysis: The governing principle was that natural justice requires the assessee's attention to be drawn to the material relied upon, but not necessarily disclosure of confidential sources or compulsory examination of the informant. The Court found that the assessees were furnished the relevant particulars and were given access to the documents during scrutiny, enabling them to meet the material. It also held that neither the statute nor the principles of natural justice required the officer to disclose the source of information, to supply copies of confidential statements, or to summon and examine third parties in the presence of the assessee, especially when the assessee had not made a proper request at the relevant stage and had not produced evidence to displace the estimate.

Conclusion: There was no breach of natural justice on these grounds, and the challenge failed.

Issue (iii): Whether the assessment was vitiated for want of proper opportunity and non-compliance with the procedure under rules 8 and 9.

Analysis: Rule 9 embodied the requirement that, before proceeding under rule 8, the dealer should be called upon to produce accounts and prove the correctness and completeness of the return. The Court held that the rule did not require a single composite notice in any fixed form, and substantial compliance was enough if the dealer was given a meaningful chance to explain the discrepancies. The notices issued in the case, read with the subsequent opportunities granted, satisfied that requirement. The Court further held that the officers were not acting on mere suspicion, but on material that supported an honest best judgment estimate, and that there was no prejudice from the absence of any further enquiry after the final notices.

Conclusion: The assessment procedure substantially complied with rules 8 and 9, and the estimate of turnover was valid.

Final Conclusion: The assessments were upheld as lawful best judgment assessments made on relevant material after adequate opportunity, and the appeals were without merit.

Ratio Decidendi: In a best judgment assessment under sales tax law, the authority may rely on relevant material beyond the assessee's bare account books, need not disclose confidential sources or examine third parties as witnesses, and the assessment will stand if the assessee was given a fair opportunity and the procedure was substantially complied with.
