Singh's counsel Ashok Mathur has contended that his client's plot is also for residential purposes.

'This is borne out by the fact that Greater Noida Development Authority has even fixed the circle rate of the area, where his land lies, at Rs.8,000 per square metre. This clearly indicates the entire land of the village has been considered as abadi (residential) land,' said Mathur.

Complaining about the government's alleged bias in favour of the chief minister, Singh said the government had gone to the extent of changing the category of Mayawati's plot from agricultural to non-agricultural to keep it out of the ambit of acquisition.

The conversion took place in May 2006, a year before the notification to acquire land was issued, Singh said in his lawsuit.

Questioning the protection granted to Mayawati's plot, Singh has also assailed the acquisition order on the ground that Badalpur village was beyond the notified area of the Greater Noida Development Authority.

He has alleged that the authority has so far failed to develop 60 percent of the area it acquired after it came into existence in 1991.

Greater Noida Development Authority had issued the acquisition notification of land in Badalpur in June 2007 under an emergency clause. The Uttar Pradesh government wants to develop the area to attract foreign investors to the region.
