It was further held, that, since only notification allotting the site was challenged and not the conversion of site from public park to private nursing home and once the scheme was altered and the area reserved for park was converted to be an area reserved for civic amenity the contention of the petitioners that the BDA had allotted 140 the site for a purpose other than to which the land was reserved, had no basis at all for the fact that after alter ation brought about by Government under order dated 27th March, 1976, the site in question was only reserved for a civic amenity generally and not for a part specially. ' Two other subsidiary submissions which in fact are now the principal issues, that the BDA had no power to alter the scheme ', and in any event a site reserved for a civic ameni ty could not have been allotted for construction of a hospi tal" also did not find favour as the scheme could be altered under Section 19(4) of the Act and it was done with approval of State Govt.
