Statutory tax benefits depend on compliance with conditions; no prejudice or valid election meant assessment stood.

Reasonable opportunity before best judgment assessment under section 12(2)(b) was required where the return appeared incorrect or incomplete, but the assessment was not vitiated because the disclosed turnover was accepted and no prejudice was shown. Deduction under rule 20(2) for coconut or groundnut oil manufacture was available only to a dealer who had applied for and obtained manufacturer registration at the relevant time; later registration did not qualify the assessee, so the deduction was unavailable. Filing monthly returns did not by itself entitle the assessee to assessment under rule 17, because that method depended on a valid election and compliance with its conditions; the annual assessment therefore could not be disturbed on that basis.

Issues: (i) Whether assessment under section 12(2)(b) was vitiated for want of a reasonable opportunity to prove the correctness and completeness of the return; (ii) Whether deduction under rule 20(2) could be claimed without registration as a manufacturer at the time of manufacture; (iii) Whether filing monthly returns entitled the assessee to be assessed under the method in rule 17.

Issue (i): Whether assessment under section 12(2)(b) was vitiated for want of a reasonable opportunity to prove the correctness and completeness of the return.

Analysis: The proviso to section 12(2)(b) required a reasonable opportunity before best judgment assessment where the return appeared incorrect or incomplete. Even assuming that no such opportunity was specifically given, the assessment did not alter the returned turnover and accepted the figure disclosed by the assessee. In the absence of any prejudice or damage, the omission did not justify interference.

Conclusion: The assessment was not liable to be quashed on this ground.

Issue (ii): Whether deduction under rule 20(2) could be claimed without registration as a manufacturer at the time of manufacture.

Analysis: Rule 20(1) linked the benefit to a dealer who applied for and obtained registration as a manufacturer of coconut or groundnut oil and cake. Rule 20(2) conferred the deduction only on such a manufacturer. The assessee was not registered during the accounting period or at the time the oil was manufactured, and registration was obtained only later. The deduction was therefore unavailable.

Conclusion: The disallowance of deduction under rule 20(2) was correct.

Issue (iii): Whether filing monthly returns entitled the assessee to be assessed under the method in rule 17.

Analysis: Rule 14(1) prescribed the ordinary annual return, while rule 17 permitted an alternative assessment method only if the dealer made the prescribed election and complied with its requirements. The assessee's turnover exceeded the relevant threshold, but no valid election under rule 17(1) was made. Mere filing of monthly returns did not substitute for compliance with the rule or compel assessment under the alternative method.

Conclusion: The annual assessment could not be challenged on the basis of the monthly returns filed.

Final Conclusion: No ground for judicial interference was made out, and the assessment and connected administrative orders were sustained.

Ratio Decidendi: A statutory benefit or alternative assessment method can be claimed only on compliance with the conditions that confer it, and absence of prejudice defeats challenge to an assessment where the disclosed turnover itself is accepted.
