(3) Schedule 6 to the [1972 c. 9 (N.I.).] Local Government Act (Northern Ireland) 1972 shall apply for the purposes of the acquisition of land by means of a vesting order made under this Article in the same manner as it applies to the acquisition of land by means of a vesting order under that Act subject to the modifications set out in Schedule 3.
