1% VAT taxation in Maharashtra for Flats Registered

Hi,

The Maharashtra goverment has come up with the new 1% VAT taxation for all the Flats Registration done on or after 1st April 2010. My query is before 1st April 2010, did the taxes for the sale of the Flats were borne by the builder? If yes what was the tax percentage? and also why the 1% VAT tax has now to be borne by the buyer? I am asking this question, because recently i did my flat registration and the builder has asked for the 1% VAT check in the name of the builder. Also my registration was supposed to happen on 26th March 2010, but the builder delayed it intentionally and pushed it to 9th April 2010. My query is by postponing my flat registration, does the builder gain in any way? for i know i am at loss as i have to now pay extra 1% VAT on the sale agreement amount.
Also can you please confirm if the VAT was applicable to builder earlier for building a township. For the builder never discussed about the VAT earlier during the negotiations, which means it was either included in the cost of the flat, or it was exempt for townships.
Your prompt response would be greatley appreciated.

Thanks.
