the authorities have found that there are illegal quarrying and it is an offence under Section 4 and 4-1-A of Mines and Minerals Development and Regulation Act, which requires an enquiry under Section 36-A(3) of Minor Mineral Concessions Rules. The District Collector has also passed an order for enquiry under Section 36-A-3 of Mines and Mineral Consession Rules, therefore, the order of the District Collector rejecting the request of the petitioner for extension of lease is justified and since it has been found that some illegal quarrying has been conducted necessarily it has to be enquired. Therefore, this Court is not inclined to interfere with the order of the District Collector. Hence, this writ petition is dismissed. No costs. Consequently, connected miscellaneous petitions are also closed.
