Service tax exclusion for human sample collection and forwarding upheld where activity was not promotion or marketing.

Collection and forwarding of human blood, urine and stool samples by a collection centre was treated as outside business auxiliary service because the activity was limited to drawing, initial processing, preservation and transmission to a principal laboratory. The Court noted that the definition of technical testing and analysis is wide but expressly excludes testing or analysis in relation to human beings or animals, and that a specific exclusion cannot be overridden by recasting the same activity under a broader residuary category to sustain taxability. The incidental use of the principal's name did not convert the activity into promotion or marketing. The service was therefore held not taxable on the revenue's theory.

Issues: Whether the collection and forwarding of human blood, urine and stool samples by the assessee's collection centre fell within "business auxiliary service" and attracted service tax, or whether the activity was covered by the exclusion applicable to "technical testing and analysis" in relation to human beings.

Analysis: The assessee's function was limited to drawing samples, carrying out essential initial processing, preserving and forwarding them to the principal laboratory. The statutory definition of "technical testing and analysis" is wide, but it expressly excludes testing or analysis in relation to human beings or animals. The Court also applied the principle that where a legislature has provided a specific entry or exclusion, the revenue cannot shift the same activity into a general residuary or broader category merely to sustain taxability. The collection centre's role was not one of promotion or marketing of the principal's services, and the incidental reference to the principal's name did not change the true character of the activity.

Conclusion: The activity did not fall within "business auxiliary service" and remained outside the taxable net on the footing adopted by the revenue. The issue was decided in favour of the assessee.

Ratio Decidendi: A service specifically excluded by the legislature from a taxing entry cannot be reclassified under a broader general entry merely because it is incidentally connected with the principal's business.
