Recovery of investment with interest

This is for your kind information that Allahabad High court  order that there shall be no construction within 500
meter from the mid stream of the Ganges and adjoining places across Sangam on the other side of the city by the Allahabad Development Authority on dated 28.03.2011.

and booking is 3 years before

So, it is not advisable to sue company on this ground.

sir then how can our family get relief.as it isnt sure dat for how long the stay happens.and other notable thing is that our plot is not within that prohibited land.some part of the land of the developers company is under restriction

so the stay has been over the whole project.suggest

It is better to get the transfer transaction cancelled and recover your money by pressurising the seller (the vendor may or may not agree to take back sold plot).

Whatsoever, it was your duty,  to find out such restrictions before finalisation of deal.
