Can a public road be leased to a private primary school.
Our madhuvan layout and setback plan was sanctioned in 1978. 15 ft service road has not only been shown in layout plan, but IT IS MENTIONED IN EACH PERPETUAL SUBLEASE of plots from house no 68 to 77.
The plots allotted in 1978 and the DOORS OF ALL THESE HOUSES OPEN IN SERVICE ROAD, now merged by UNIVERSAL PUBLIC SCHOOL in their plot.
Even references to commissioner mcd or chief secretary has DELHI ADMINISTRATION could not get information from MCD
NOW SDM PREET VIHAR IS ON RECORD That school and society have different area plans.
SCHOOL CAME IN 1984 and afterward but madhuvan houses were built with approval of DDA much warier and their back doors open now in school.
MCD OFFICERS SHIRKING AND NOT CARRYING OUT SITE INSPECTION and submitting report to CHAIRMAN PUBLIC GRIEVANCES COMISSION.
Already CIC HAS adversely commented against SE BUILDING SDAHDARA south zone.
KINDLY ADVISE WHAT residents should do as this road has been BLOCKED FROM THREE POINTS?
