CIDCO will not interfere in this issue until an aggrieved person is drawing the cidco into the court or consumer forum.
The fact is that the subsequent registration of the already registered property will be invalid and a fraudulent act attracting severe punishment under criminal laws for cheating and breach of trust , criminal conspiracy and many more such offences.
Have you not taken a legal opinion before purchasing the property or whether you have not verified at least the encumbrance certificate before making payment for purchase?
They have not cancelled the registration but still the new developer ie.Sughadh construction is selling n making registration of the flats with new buyers. Is this legal?
No this is not legally valid,especially if the previous buyer is claiming the property on he basis of the registered sale deed favoring him, you will be in a problem.
And can a new registration be done by other builder for the same flat without cancelling the previous reg. as in this case?
No he cannot do it, this amounts to fraudulent act and cheating, he has to cancel the previous registered sale deed for selling the property to a new buyer.
How can cidco transfer the plot to new developer without settling or cancelling the registration of previous buyers
cidco has no business to transfer the property to the new buyers, the aggrieved persons have to make representation to cidco with their genuine reasons.
