(1)Where—
(a)the Secretary of State formerly accepted land as diplomatic or consular premises but did not accept it as such premises immediately before the coming into force of this section; or
(b)land has ceased to be diplomatic or consular premises after the coming into force of this section but not less than 12 months before the exercise of the power conferred on the Secretary of State by this subsection,
the Secretary of State may by order provide that this section shall apply to that land.
(2)The Secretary of State shall only exercise the power conferred by subsection (1) above if he is satisfied that to do so is permissible under international law.

(4)An order under subsection (1) above shall be made by statutory instrument, and a statutory instrument containing any such order shall be subject to annulment in pursuance of a resolution of either House of Parliament.
(5)The Secretary of State may by deed poll vest in himself such estate or interest in land to which this section applies as appears to him to be appropriate.
(6)A deed poll under this section may also comprise any portion of a building in which the former diplomatic or consular premises are situated.

(b)unless he considers it inappropriate or impracticable to do so, serves a copy of the certificate on the owner of any estate or interest in the land.
(10)Where—
(a)circumstances have arisen in consequence of which the power conferred by subsection (1) above is exercisable; but
(b)the Secretary of State serves on the owner of the land in relation to which it has become exercisable notice that he does not intend to exercise the power in relation to that land,
it shall cease to be exercisable in relation to it in consequence of those circumstances.
(11)If—
(a)the Secretary of State has exercised the power conferred by subsection (1) above in relation to land; but
