Challenge in this appeal is to the judgmentof a Division . r Bench of the Madhya Pradesh High Court dismissing the writ petition and miscellaneous petitions filed by the appellant. G 3. Factual position as projected by the appellant before the High Court is as follows: The appellant is a Government Company. Its 'Malanjakhand I Copper Mining & Ore Concentration Project' is situated in H District Balaghat, where it 'is engaged in. extraction of copper HINDUSTAN COPPER LTD. v. STATE OF MADHYA 437 PRADESH AND ORS. [DR. ARIJIT PASAYAT, J.] ore, by open cast mining process. The appellant has·de$cribed A the. process. thus: After drilling and blasting the ore in the open pit mine, the ore in the form of boulders are transported to t~e Primary Crusher (situated at a distance of 2.53 Km from the Mine), where it is crushed into pebbles/pieces. Such crushed ore is then carried on ·a conveyor to a Secondary CriJsher. B (situated at about 5 Km· from the mine) for further crushing into smaller pebbles: The small pieces/pebbles are then carried by a conveyor to the Concentrator Plant (situated at 5.5 km from the mine). In the Concentrator Plant, the ore is milled into powder in the Ball Mills. Such powder mixed with water is C carried in the form of slurry to floatation cells. 1·n the floatation cells, the slurry is subjected to Froth Floatation Process and the copper concentrate is removed and dried in vacuum Driers and stored in Concentrate Storage Sheds. The tailing pumps are at a distance of 8 km. From the Large quantity of water is D required for Concentrator Plant for being used in milling. Water is also required for the factory township. The required water is pumped from the· mines through pumps located at an Intake Well'(situated at a distance of 10 Km from the mine). From the intake well, water is pumped to Water Treatment Plant (situated E at a distance of6 km from the mine). · · According to the appellant, its activities consist of two distinct parts. First is mining, that is drilling, blasting and collecting of ore which is carried on .at mine pit. This activity is F Cc;irried on in the mine area registered under· the Mines Act, 1952. The second is processing, which is carried on at the Primary Crusher, Secondary Crusher and Concentrator Plant. The processing (manufacturing) part of the activities are carried in the factory area. The Primary Crusher, the Secondary G Crusher, the Ball Mill, the Concentrator Plant, the Tailing Pumps, the intake well and the Water Treatment Plant are situated away from the mine, at distances varying 2.5 KM to 10 KM and are registered separately as a 'Factory' under the provisions of Factories Act, 1948.

Electricity DL1ty Act, 1949 (for short 'the Act') A enacted by the State Legislature provides for levy of electricity duty (for short 'the duty') on sale or consumption of electrical energy, Section 3 of the Act provides that every distributor of electtlcal ehergy and every producer shall pay every month to the Stale Government at the prescribed time and in the B ... r prescribed manner, a duty calculated at the rates specified (in the iable given below the Section ) on the units of electrical energy sold or supplied to a consumer, or consumed by himself for his own purposes or for purposes of his township or colony, during the preceding month. Part- B of the Table prescribes the c rate of electricity duty on the electrical energy sold/supplied.for consumption for different specified purposes, namely domestic, non-domestic & Commercial, industrial and non- industrial. Industrial purpose is further divided into four categories, one of which is 'for mines other than captive mines of a Cement D industry' (vide Energy 3). The term 'mine' is defined in the ~ _)i.- Explanation (b) to Section 3 of the Act, as 'a mine to which the Mines Act, 1952 applies and includes the ·premises or machinery situated in or adjacent to a mine and used for cr.ushing, processing, treating and.transporting the mineral'.

STATE OF MADHYA 441 PRADESH AND ORS. [DR. ARIJIT PASAYAT, J.] > ~ ·The appellant states that the Act as it originally stood, subjected all factories· whether they were independent, or associated with mines, to the same rate of duty. The Act was amended by Amending Act No. 21 of 1978. After such amendment, the Table Under Section 3 prescribed the 'duty' at the rate of 2 paise per unit in regard to factories. In regard to B consumers for trade, commerce and business purposes, the ---~ rate of duty was 12 paise per unit. Thus, the Act No. 21 of 1978 prescribed a lower rate of duty for factories when compared to commercial establishments. The Act was again amended by Amending Act No. 21 of 1986 drastically changing the rate of c duty, as also the classification. It prescribed a lower rate of duty for non-domestic and commercial purposes at the rate of 15 parse per unit, when compared to certain classes of industries. It classified Factories into four kinds of industries, for levy of differe_n,t rates of duty, namely, (i) mines other than captive mines D of cement industries, (ii) Cement industries including its captive mines, (iii) industries receiving electricity at the' low tension tariff, ' I>- _).- and (iv) other industries. An eXtended definition of the word 'mine; was also added. The appell~nt is aggrieved by the said extended definition E of 'mine' the effect of which is to _make processing a part of mining and the prescription of a higher rate of duty for 'mines' (that is composite activity of mining and processing), while . . prescribing a lesser rate for other categories of industries. The appellant contends that- the extended definition of 'mine' in F 1· Explanation (b) contained in the Table under Secti0n 3 results in dissimilar treatment to similar subjects, by prescribing different rates for different factories. It was contended that the definition has the effect of categorizing factories registered under the Factories Act into two categories (a) those which are G adjacent to a mine and l_.Jsed for crushing, processing, treating A. and transporting the mineral; and (b) other factories. It was also submitted that classification of factories into two categories based on their proximity or otherwise to a mine is unreasonable and irrational having no connection with the H \·· ~ A object sought to be achieved by the Act. fhe nature of sale, supply and consumption of electrical eherg·y· fo both classes of factories is in all respects similar and there is no reasonable justification to prescribe a higher rate. of duty to factories adjacent to a mine by including them under the extended B definition of 'mine·· In .the absence of a further definition of the expression 'adjacent to the mines' is vague and ambiguous leading to discriminatc;>ry treatment by the Authorities implementing the Act and, therefore, fnvalid. Lastly, it was con.tended that its.processing plant, thatis,.thePrimary Crusher, c the Secondary Crusher, the Ball Mill, the Coneentrator Plant, the Tailing Pumps, ttie.lntake.w~ll and-the water"treatment;plant is not situated 'adjacent' to its mine and th~refore could. not be treated as 'mine' for the purpose of levy o_f electrici.ty'duty. . . Feeling aggrieved by the extended definition. of 'mine' in D Explanation (b) to Section 3 of the Act and feeling aggrieved by the.inclusion of its 'Processing factory'within the 'mine' for purposes of levy of electricity duty, the appellant ff led the writ petition on 19.7.1988 before the High 'Court for the following reliefs: ·(a) to declare the provisions of Section 3 of the M.P. Electricity Duty Act, 1949, that is the entry' in theTaole (Part B), relating to 'mines other than captive mines of cement :industry' and the Explanation (b) defining 'mine' :as uncbnstitutional. (b) as a consequence, to direct the respondents to' treat the petitioner's processing unit (Primary Crusher, th·e Secondary Crusher, the Ball Mill, the Concentrator Plant, the Tailing Pumps, the Intake Well and the Water Treatment Plant), as not included under the definition of 'min.e' but included in the G category of 'non-domestic and commercial establishmentsi for purposes of imposition of electricity duty ·at the lower rate prescribed as 12 paise/15 paise per 1Jnit based .on its consumption; and H (c) to direct the refund of the excess duty collected. . . . .__ .
