The assessee is a dealer in motor cars, trucks, scotoers, motor spare parts ·and certain other goods. He returned a turnover of Rs. 42,09,912.12 for the assessment year 1961-62. The Commercial Tax Officer on scrutiny of accounts determined the turnover at Rs. 68,06,331.49. During the assessment proceedings it was found that the assessee had not included in the monthly return in Form A-2, three !terns ot' turnover. The first was a sum of Rs. 1,95,311.21 relating to delivery charges which the assessee had paid to certain Calcutta dealers from whom he had made purchases of cars, trucks, scooters etc. The second item was of Rs. 2,21,247.97 which relat- ed to the sales of motor parts. The third item was of Rs. 1,56,539.25 being the aggrega\e of the sale proceeds of firewood. The assessing authority served a notice on the assessee to show cause why these items should not be brought to tax. The assessee filed objections which were rejected. The assessing authority found that th~ delivery charges paid by the assessee were included in the cost price when the cars, trucks, scooters etc. were sold by it and sales tax at 7 % had been collected by the assessee on the delivery charges. As regards the second item it was held that the assessee had failed to maintain separate accounts contrary to the rules in respect of the first sales of parts and as it was not possible to separate the fjrst sales from the general entries in the account books it was necessary to make assessment on J:iest judgment. The assessment was completed but certain penalty was levied o:n the assessee. The assessee appealed to the Appellate Assistant Commissioner who took the view that the failure of the assessee to disclose the taxable turnover in the monthly returns was due to a bona fide impression on the assessee's part that it would ~e sufficient if correct figures were furnished at the time of the final assessment. He, therefore, imposed a nominal penalty. The Board of Revenue in exercise of its power under s. 34 of the Act set aside the order of the Appellate Assistant Commissioner. According to the Board's findings the failure of the assessee to disclose the turnover in question was deliblerate and called for no lenient treatment. An appeal was filed against the order of the Board of Revenue to the Madras High Court. The High Court allowed the appeal so far as the first and third items were concerned. As regards the second item it decided against the assessee.
