“In the result, the impugned circulars Exts.P3 to P5 in this Writ Petition and Ext.P7 in W.P.(C). No.15274/2008 to the extent they stand in the way of using pre-KER buildings, which are strong and certified to be fit by the competent authority, are declared ultra vires and unenforcible. It is clarified that the various other directions in the impugned orders/letters/circulars, concerning the steps to be taken for the safety of the students and teachers and demolition of unsafe buildings, are not interfered with. In view of our above finding, the concerned Engineer (going by the materials on record, we find it is the Assistant Engineer of the Local Self Government Department having jurisdiction over the area) is directed to inspect the schools of the petitioners immediately and decide whether they are entitled to get fitness certificates for their pre-KER buildings, so that they could house the class divisions in them. This, the said officer shall do within two weeks from the date of production of a copy of this judgment and the results shall be communicated to the Managers forthwith.”
