Can a housing society seize and sell a flat?

Is it possible for a housing society to seize a flat for a valid reason? If for example, the flat belongs to a builder who has not delivered on what he promised. Like for example less area, no swimming pool etc etc. Can a society complete construct the promised facilities by seizing and selling the flat that is owned by the builder?

80 GG deduction benefit for Family Pension Assessees?

Whether benefit of deduction u/s 80GG available for an assessee who gets a family pension ?

The assessee is a widow and does not have a residential property of her own or in the name of her immediate family. She lives in a rented property and has rental receipts for the same.

There is some confusion that u/s 80 GG is only available for assessees who are salaried or self-employed. Is this true ?

Is it possible to claim deduction u/s 80GG from the family pension income credited to her bank a/c during 07-08 FY particularly when family pension is taxable under the ‘income from other sources’ and not ‘head salary’?
