the site was finalized and lands of different habitants were acquired for the purpose of construction of Tehri Dam. Land so acquired was handed over to Tehri Dam Project. Earlier, entire project was going on under the supervision and management of Irrigation Department of Uttar Pradesh. Initial construction work was done by the Irrigation Department of U.P., however, in the month of July, 1988, the Tehri Hydro Development Corporation was constituted / incorporated. THDC, Government of India and Government of Uttar Pradesh, agreed that 12% of the generated electricity shall be supplied to the State of U.P. free of cost. For the purpose of construction of Tehri Dam, huge chunk of land was dug and ultimately, Tehri Dam, as dreamed of, came into existence. The State Government decided to recover the royalty and penalty from the petitioners saying petitioners were involved in illegal mining of minerals within Tehri Dam and Koteshwar Dam areas without taking mining lease / license, as required under Section 4 of the Mines and Minerals (Development and Regulation) Act, 1957, therefore, were liable to pay royalty and penalty under Section 21 (5) of the Act. Feeling aggrieved, petitioners have approached this Court by way of filing present writ petitions.
