Sale of goods versus works contract: bus-body fitting turns on how property in materials passes on delivery.

Supply and fitting of bus-bodies on customer-furnished chassis is analysed by reference to whether property in the materials passes as a finished chattel on delivery or by accretion during construction; on the stated facts, the surrounding documents pointed to a sale of goods rather than a pure works contract. The note also explains that the appellate authority's power to enhance assessment in a taxpayer's appeal extends to the whole assessment, not only the item specifically challenged. It further states that such enhancement is exercised under appellate power and is therefore not controlled by the limitation period applicable to escaped assessment proceedings.

Issues: (i) Whether the supply and fitting of bus-bodies on chassis supplied by customers constituted a sale of goods or a works contract. (ii) Whether, in an appeal by the assessee against part of the assessment, the Appellate Assistant Commissioner had power under the sales tax statute to enhance the assessment by examining and taxing an unchallenged item. (iii) Whether the enhancement was barred by limitation.

Issue (i): Whether the supply and fitting of bus-bodies on chassis supplied by customers constituted a sale of goods or a works contract.

Analysis: The decisive test was whether property in the materials used by the dealer passed to the customer as a finished chattel on delivery, or whether it passed by accretion during the process of construction and affixture. The terms disclosed by the repair order forms, the separate valuation of several items, the risk clause, and the delivery practice indicated that the completed bus-body was intended to pass as a specific finished article fitted on the chassis. The materials did not pass to the customer stage by stage during construction, and the surrounding documents supported a transaction of sale rather than a pure contract of work and labour.

Conclusion: The transactions were sales of goods and not works contracts, though the matter was remitted to the Tribunal for fresh consideration if the actual contracts were produced.

Issue (ii): Whether, in an appeal by the assessee against part of the assessment, the Appellate Assistant Commissioner had power under the sales tax statute to enhance the assessment by examining and taxing an unchallenged item.

Analysis: The power to enhance in appeal was held to extend to the entire assessment and not merely to the specific item challenged by the assessee. The appellate authority was treated as a revising authority with power to examine every process leading to the assessment, and the statutory language and scheme of appellate and revisional powers supported that wider construction.

Conclusion: The Appellate Assistant Commissioner had jurisdiction to enhance the assessment on the bus-body turnover even though that item had not been specifically challenged in the appeal.

Issue (iii): Whether the enhancement was barred by limitation.

Analysis: The enhancement was made in the exercise of appellate power under the relevant provision and not as a case of escaped assessment. On that basis, the time-limit applicable to escaped assessment proceedings did not govern the action taken by the appellate authority.

Conclusion: The enhancement was not barred by limitation.

Final Conclusion: The legal questions on character of the transactions, appellate power to enhance, and limitation were answered against the assessee on the main points, but the matter was sent back for fresh disposal on the limited question of the actual contracts, if produced.

Ratio Decidendi: In an appeal under the sales tax law, the power to enhance assessment extends to the whole assessment and, on the facts proved, a transaction in which a finished bus-body is supplied and fitted on customer-furnished chassis may amount to a sale of goods rather than a works contract.
