effect from the date of expiry of the period of renewal last made or till completion of renewal period, if any, or a period of fifty years from the date of grant of such lease, whichever is later. Similarly Section 8A (6) of the Act provides that where the mineral is used for other than captive purpose, the period of lease shall be extended and be deemed to have been extended up to a period ending on the 31st March, 2020 with effect from the date of expiry of the period of renewal last made or till completion of renewal period if any, or a period of fifty years from the date of grant of such lease, whichever is later. Section 8A (3) of the Act provides that all mining lease granted before commencement of the Amendment Act shall be deemed to have been granted for a period of 50 years. As per Section 8A(3) of the Act the fifty years was expired on 14.09.2016. Therefore, when the petitioner sought extension of validity of the mining lease, the claim of the petitioner has been rejected under Section 8A (5) of the MMDR Act, 1957. The order impugned only states that the proposal for extension of validity of the lease under Section 8A (5) of the MMDR Act, 1957 lease is inadmissible as per law and hence the prayer of the petitioner for extension of the said lease is rejected.
