Full Judgment
Their trailer was, therefore, a mechanically propelled one, pleaded the appellants, and hence not covered by heading 87.13/14.
2. The learned representative of the department stated that all trailers had to be pulled by another vehicle. Therefore, the condition in heading 87.13/14 "not mechanically propelled" had to be interpreted to mean that the vehicle falling in that heading should not have a prime mover installed on the vehicle itself. Otherwise, specific mention of "trailer" in that heading would become meaningless.
3. On careful consideration of the matter, we agree with the view of the learned representative of the department. Heading 87.13/14 is a specific one for trailers and it makes no distinction between ordinary trailer and heavy duty trailers. We uphold the lower orders and reject this appeal.
