This writ petition was filed seeking the issue of a writ of certiorari against Ext.P4 and P5 quarrying permits and also for a writ of mandamus declaring that respondents 5 and 6 are not entitled to carryout quarrying operations in Block No. 32 re-survey Nos. 16/3-2, 12/9-2 and12/9 of Veliyam Village, Kottarkara Taluk in Kollam district without obtaining environmental clearance. While admitting the writ petition, this court had passed an interim order to the effect that any quarrying operations carried out by respondents 5 and 6, as per Exts.P4 and P5, shall be interdicted if the same is carried on without any environmental clearance. When the matter was taken up for final hearing, it was brought to the notice of this court that pending the writ petition, the validity period of P4 and P5 permits have expired and that respondents 5 and 6 have not been able to procure environmental clearance for the purpose of conducting the quarry. In such circumstances, the writ petition is closed, reserving the liberty of respondents 5 and 6 to take appropriate measures for submitting the applications before the appropriate authorities for obtaining the requisite clearances and licenses for the purpose of conducting the quarry, if so advised.
