A. H. Saikia, J. — This is a reference by the learned Single Judge referring the following question for an authoritative pronouncement. The Hon'ble Chief Justice was pleased to constitute this Full Bench to decide the said question of law. "Whether the consignment of notified agricultural produce which are being transported into the declared market area in the State of Assam are liable to cess under section 21 of the Act even before their sale and purchase in the market area in view of the decisions of the Supreme Court in Ram Chandra Kailash Kumar & Co, reported in 1980 (Suppl) SCC 27 and in Shalimar Chemical Works Ltd reported in (1997) 5 SCC 516 ? 2. Pronouncing the order dated 17.8.99 in Civil Rule No. 1142 of 1997 (Tinsukia Trading Co & others vs. State of Assam & others) filed by the petitioner's firm questioning the legality and validity of realization of cess under a the provisions of section 21 of the Assam Agricultural Produce Market Act, 1972 (for short, the Act) and Rule 21 (7) of the Assam Agricultural Produce Market (General) Rules, 1975 (for short, the Rules), the learned Single Judge observed that the decision of the Division Bench of this Court in Anjali Trading Co vs. Assam Agricultural Marketing Board & others reported in (1998) 1 GLR 111 (1997 (2) GLJ 633) affirming the decision of the learned Single Judge in Anjali Trading Co vs. Assam Agricultural Marketing Board & others reported in (1995) 3 GLR (1995 (2) GLJ 242) holding that the consignment of notified agricultural produce which are being transported into declared market area in the State of Assam are liable to cess even before their sale or purchase in the market area is at variance with the decisions of the Apex Court in Agricultural Market Committee vs. Shalimar Chemical Works Ltd, (1997) 5 SCC 516 and Ram Chandra Kailash Kumar & Co vs. State of UP reported in 1980 (Suppi) SCC 27. That is why the present reference was made to this Full Bench. 3. That is why the present reference was made to this Full Bench. 3. These batches of writ appeals as well as writ petitions have been brought under judicial scrutiny in order to determine the common questions as to : (i) Whether the provisions of Rule 21 (7) of the Rules is ultra vires inasmuch as the State Govt in exercising Rule making power under section 49 of the Act has widened the scope of 'presumption' by providing number of other factors beyond its Legislative competency ? (ii) Whether the Assam Agricultural Marketing Board, (for short, the Board) has the power to collect levy and cess of the agricultural produce in the market area e as per section 21 of the Act, merely on the basis of Resolution adopted by the Board? (iii) Whether the Board and its employee arc justified and empowered to realise cess on the agricultural produce at different check gates on the National High Way in Assam, particularly elected at Srirampur, New Guwahati, Jagiroad, Jorhat, Titabar, and Dergaon for such purposes ? (iv) Whether the respondents-State Govt may be directed to refund the cess already realised by it ? 4. The common facts in brief, involved in all these cases in hand, are that the appellants/writ petitioners purchased the agricultural produce i.e. Rice, broken rice, wheat, mustard oil etc from different places in Punjab, Haryana, Uttar Pradesh by paying marketing cess to the Marketing Committee of those respective places and thereafter the said agricultural produce are imported to Assam by road and rail. When the trucks loaded with agricultural produce pass through Srirampur Check Gate on the Assam Bengal Boarder and Jagiroad Check Gate (after unloading the consignment of agricultural produce transported by rail at Guwahati), cess is realised at those check gates by the Agricultural Marketing Board though the notified agricultural produce are not sold in any such market area. Agricultural h produce are ascertained goods and are in deliverable State and as such, the sale of agricultural produce is complete in the State of Punjab, Haryana and UP from where the respondents purchased the agricultural produce. The Board has no authority or right to erect check gates on National Highway and realise cess on those check gates from the trucks carrying agricultural produce although no sale or purchase of transaction takes place at those places declared as market area. 5. We have heard Mr. The Board has no authority or right to erect check gates on National Highway and realise cess on those check gates from the trucks carrying agricultural produce although no sale or purchase of transaction takes place at those places declared as market area. 5.
