Nearly four decades ago, Haryana govt had acquired more than 1,500 acres of land at Panchkula for Sectors 24 to 28 and sold the plots to individuals. Later, various authorities one after the other increased the compensation payable to farmers for their land over the next decade. Intimating plot buyers earlier, Haryana Shahari Vikas Pradhikaran (HSVP) sent additional demand notices to them for a corresponding increase in plot prices.
