(1) Any person whose property is injuriously affected by virtue of any of the provisions contained in any regional plan, master plan, detailed development plan or a new town development plan made under this Act shall, if he prefers a claim for the purpose to the Tribunal with such particulars and within such period as may be prescribed, be entitled to obtain compensation in respect thereof as determined by the Tribunal:
Provided that property shall not be deemed to be injuriously affected by reason of any of the provisions inserted in any development plan which impose any condition or restriction in regard to any of the matters specified in clause (f) of sub-section (2) of section 15, or in clauses (k) and (l) of sub-section (2) of section 17 or in clauses (m) and
(n) of sub-section (1) of section 20, as the case may be.
(2) If, at any time after the day on which any regional plan, master plan, detailed development plan, or a new town development plan has come into force, such plan is varied, or revoked, any person who has incurred any expenditure for the purpose of complying with such plan, shall, if he prefers a claim for the purpose to the Tribunal with such particulars and within such time as may be prescribed, be entitled to obtain compensation in respect thereof as determined by the Tribunal, if by reason only of the variation or revocation of such plan, such expenditure has ceased to be in any way beneficial to him.
