[Article 83] Federal Constitution 77 (2) Where in accordance with Clause (1) the Federal Government requires the State Government to cause to be made a grant of land in perpetuity, the grant shall be made without restrictions as to the use of the land but shall be subject to the payment annually of an appropriate quit rent and the Federation shall pay to the State a premium equal to the market value for the grant; and where the Federal Government so requires the State Government to cause to be granted any other interest in land, the Federation shall pay to the State the just annual rent therefor and such premium, if any is required by the State Government, as may be just: Provided that if the value of the land has been increased by means of any improvement made (otherwise than at the expense of the State) while the land was reserved for federal purposes, the increase shall not be taken into consideration in determining the market value, rent or premium for the purposes of this Clause. (3) Where a requirement is made under Clause (1) in respect of any land which, at the date of the requirement, was intended for any State purpose, then if— (a) other land is acquired by the State for that purpose in substitution for the first-mentioned land; and (b) the cost of the land so acquired exceeds the amount paid by the Federation (otherwise than as rent) in accordance with Clause (2) in respect of the interest granted to the Federation, the Federation shall pay to the State such sum as may be just in respect of the excess. (4) Where a further grant is made in pursuance of this Article in respect of land an interest in which is vested in the Federation or any public authority, any sums payable by way of premium under Clause (2) in respect of the further grant shall be reduced by an amount equal to the market value of any improvements made (otherwise than at the expense of the State) since that interest became vested as aforesaid.
