Vesting of property transfers tax-acquired immovable property to Central Government, enabling possession and enforcement against prior transferees. Once an acquisition order under section 269F is final, the competent authority may require surrender of possession of the immovable property and, if necessary, take possession using force or police assistance; upon surrender or taking of possession the property vests absolutely in the Central Government free from all encumbrances, though liability for such encumbrances remains enforceable against transferees by suit for damages. Final orders concerning specified rights in buildings operate by their own force to vest those rights in the Central Government and the authority may issue directions to effect compliance.
