M/S Oswal Petrochemicals Ltd. v. Commissioner of Central Excise Mumbai II
Background
Oswal Petrochemicals had classified its products Benzene and Toluene under a tariff heading that attracted a lower/exempted duty, and this classification was approved by the tax authorities in 1990. Months later, the department drew samples, tested them, and claimed the products were actually less pure than the threshold required for that classification, but only shared a brief "gist" of the test results with the company, not the full test reports, and then demanded a large amount of differential duty going back years.
Decision Breakdown
The Supreme Court held that since the test reports were the entire basis for reclassifying the goods (and the resulting multi-crore duty demand), principles of natural justice required the company to be given full copies of those reports: merely stating a "gist" in the show-cause notice was not enough, and denied the company its right to seek a re-test within the legal time limit. The Court also held that treating certain months' assessments as "provisional" (which would have extended the limitation period for raising demands) was legally wrong, because a provisional assessment requires a formal order and an executed bond, neither of which existed here. Both the reclassification and the provisional-assessment finding were set aside, and the company's appeals were allowed.
Lesson Learnt
Tax and regulatory authorities cannot rely on evidence like lab test reports to justify a higher demand while withholding the full reports from the affected party, giving only a summary breaches natural justice; likewise, an assessment can be legally "provisional" only if the proper formal steps (a written order and a bond) were actually taken.
