Re-vesting of property when government fails to tender consideration results in abrogation of purchase order and return of possession. If the Central Government fails to tender or deposit the consideration required under sections 269UG and 269UE within the specified period, the purchase order under section 269UD is abrogated and the immovable property stands re-vested in the transferor after expiry of that period, excluding time consumed by court proceedings under the relevant sub-sections of section 269UG. The appropriate authority must declare the re-vesting in writing, deliver the declaration to persons under section 269UD(2), and restore possession to the transferor or the prior possessor.
