Full Judgment
2. It is noticed that the Collector of Customs, Calcutta has merely issued a letter of authority whereby he has authorised Sh. N.C. Rai, Asstt. Collector, Divisional Cell, Calcutta, to file an appeal against the order of the Collector (Appeals), Calcutta. This letter of authority does not indicate that Collector has independently applied his mind to find out as to whether the Order passed by the Collector (Appeals) is legal and proper in terms of Section 129A(2) of the Customs Act, 1962, which clearly lays down that the Collector of Customs, may, if he is of opinion that the Order passed by Appellate Collector under Section 129A as appealed before him is not correct or whether the Collector (Appeals) under Section 120(A) is not legal or proper direct the proper officer to appeal on his behalf to the Appellate Tribunal against such order. It is also noticed that except for the Order-in-Appeal and Order-in-Original, the Revenue has not produced the basic documents like Bill of Entry, Invoice, Catalogue and Literature. The Revenue has also not produced independent evidence to counter the respondents' contention that the twin screw functions as a single screw and the dimension of diameter of 150MM is not required to be taken as a single screw but as double screw.
3. In view of these defects in the appeal papers, we dismiss the appeal as unsubstantiated and also as non-maintainable.
