The respondent C~pany, which was itself primarily engaged in the · c manufacture of iron ond steel products, owned a colliery. The coal raised from this colliery was mainly used in the respondent's iron and steel factories though some coal was also sold to outsiders. In the years 1946-47, 1947-48 and 1948-49, the respondent Company lodged returns with the Collector of Burdwan under s. 72 of the Bengal Cess Act, 1880 in which the Company valued the coal supplied by the colliery to its factories at o rate per ton less than the actual cost of raising the coal, an_d computed B the profits of the colliery on that basis. The Cess Deputy Colfecfor, who was the assessing authority, rejected the returns and computed the profits of the colliery for the putpose of assessment to the cess by valuing the coal at the control rate in force at the time. The assessing authority under the Bengal Primary Education Act, 1930, the provisions of which were similar to the Bengal Cess Act, also computed the education cess payable by the. Company for the years 1946-47 and 1947-48 on the same basis. The Respondent Company paid the amounts assessed as cess under E each Act under protest and thereafter instituted a suit for refund of the amount which it contended was collected from it in excess. It also prayed for a declaration that it had earned no profits from the colliery <)uring the three years from the coal consumed in its own steel factories and a• such no cess could have been assessed and levied on it. The Trial Court decreed the suit ·anrl an appeal to the High Court .was dismissed.
