Dear Sir,
My answers are as follows:
1) How can BBMP issue deviation notice now after so long years?
Ans: In N number of cases the Hon’ble Supreme Court and High Courts held that such notices are liable to set aside on the ground of delay and latches.
2) Is there a provision in BBMP to amend or rectify sanction plan according to sale deed measurements?
Ans: The BBMP Authorities have every power to rectify the sanction plan since there is no encroachment over and above your purchased area as described in your sale deed.
3) What procedures to be followed for squashing this notice from BBMP?
Ans: You must get file a writ petition to quash to said notice before Hon’ble High Court.
4) What can be replied to BBMP so that they will not issue further notice of 321(3)?
Ans: You just reply saying that you will submit the reply in detail and seek 30 days time and in the meanwhile get a stay order on such notice from HC.
5) Why didn't the BBMP official check the measurement mismatch while sanctioning the plan itself? It is mistake by their side also right bcas when sanctioning the plan all docs were attached. Moreover it was sanction in the year 2004, 14 years before.
Ans: The mistake is committed by not only by you but also by the officials of BBMP and they cannot take action against you to cover up their mistake.
