—(1) Without prejudice to the operation of any other written law relating to the acquisition of land for a public purpose, any owner of land which is allocated in the Master Plan for development for a public purpose may serve on the competent authority a purchase notice requiring his interest in the land so required for that public purpose to be purchased in accordance with this section, if he —
is refused permission under section 14 to develop that land; or
has completed the development of any contiguous land belonging to him in accordance with any permission granted by the competent authority under section 14.
(2) The person serving the notice shall certify that he has the consent of every person known to him to have an interest in the land.
(3) The competent authority shall investigate every purchase notice so served and, when he is satisfied with the correctness thereof, he shall transmit the purchase notice to the Minister together with the following information:
the specific public purpose for which the land is allocated; and
any written permission granted to the owner of the land to develop it notwithstanding the allocation of the land for a public purpose.
(4) The Minister may reject a purchase notice in whole or in part where, in his opinion, the land or part thereof —
is capable of reasonably beneficial use in its existing state; or
will not be required for development for a public purpose within 5 years from the date of service of the purchase notice.
(5) Where, and to the extent that, he does not reject a purchase notice, the Minister shall declare that the land referred to in the purchase notice or any part thereof is needed for a public purpose and may order proceedings to be taken for —
obtaining possession of the land or part thereof for the State, the competent authority or any public authority; and
determining compensation to be paid to any person or persons interested therein.
(6) Such compensation shall be assessed in the manner and according to the principles laid down in any written law for the time being in force relating to the acquisition of land for a public purpose, but account shall be taken of any such written permission for development granted as referred to in subsection (3)(b).
(7) For the purposes of this section, the allocation of land in the Master Plan as being within —
a green belt; or
a conservation area,
shall not constitute an allocation for development for a public purpose.
