It is not in dispute that the buyer of the steel doors with frames is public funded research institute as it is an institution of Government of Andhra Pradesh. The issues in dispute are (a) whether these doors can be called Scientific and technical instruments, apparatus, equipment, accessories and spare parts of goods etc., and (b) whether the appellant has fulfilled the conditions in column (4) of the notification, in particular condition (i)(b). They have supplied the doors to the research institution which had certified that the doors were required for animal vaccine production. Later, they give another certificate that they were used for animal vaccine research purpose. The appellant claims that hence they are entitled to a benefit of the notification. The Revenue, on the other hand contends that the goods in question are not scientific and technical instruments or accessories etc., and are merely doors, supplied to the research institution and since the description of the goods does not match with the notification the appellant is not entitled to the benefit of notification. It is their further submission that, there is nothing on record to show that the buyer is registered with the Department of Scientific and Industrial Research (DSIR) of the Government of India at the time of clearance of the goods and therefore the condition specified in the notification is also not fulfilled. Thus neither the goods are covered by the notification nor is the condition fulfilled.
