Immunity to transferor bars transferee claims for nonconforming transfers when the Central Government orders property purchase, subject to abrogation. When the Central Government issues an order to purchase immovable property under the statutory scheme, the transferor is insulated from any claim by the transferee that the transfer did not conform to their agreement; this immunity overrides other laws and instruments but does not apply if the purchase order is abrogated under sub-section (1) of section 269UH.
