2.The case of the petitioner is that the petitioner was working as a staff nurse in Chennai and retired in the year 2004, she purchased a land at Peelamedu, Coimbatore Corporation called as Gurusmy Nagar in Plot No.152, to the extent of 20.10 square feet and the same was registered as document No.3546 on 21.06.2005 an the said land purchased after verifying the encumbrance certificate issued by the Registration Department, lay out approval accorded by Town and Country planning department on 05.03.1987 and approval accorded by the Coimbatore Corporation on 21.07.1988. At the time of purchase there were several houses constructed with the Corporation roads, street lights and drinking water supply provision in the location. According to the petitioner, she was purchased another lay out in Plot No.130, Kurusmy Nagar after verifying the encumbrance certificate, lay out of the approval etc,. The approval of lay out was given by the Director, Town and Country planning department on 05.03.01987 for about 199 plots. After purchasing the lay out, it appears that the petitioner approached the concern Tahsildar for transfer of patta, who in turn refused to grant the same, since the land including the petitioners lay out has already been acquired by the Tamil Nadu Housing Board by issuing 4(1) notification which was approved by the Government on 05.02.1992 and an award was also passed on 18.4.1995 per hectare. The grievance of the petitioner is that she was under bona fide impression that since the lay out has been approved by the Director of Town and Country Planning department and even TNEB has given power connection and Coimbatore Corporation also given water supply connection to the houses constructed therein. Since, the claim of the petitioner for grant of patta, was not considered, the petitioner made a representation to the Housing Board on 21.10.2010, requesting for exempting the lands purchased by the petitioner which was rejected . Since the Government by proceedings dated 12.2.2008, rejected the request for exempting the lands. The petitioner once again sent representation to the Housing Board on 12.02.2008, but there was no reply, which prompted the petitioner to approach this Court by way of filing this present Writ Petition, challenging the 4(1) notification and also consequential declaration.
