(1) In a suit for eviction instituted against a tenant in which the plaintiff succeeds and the defendant establishes a claim for compensation due under section 4 for improvements, the court shall ascertain as provided in sections 7 to 16, the amount of the compensation and shall pass a decree declaring the amount so found due and ordering that on payment by the plaintiff into the court of the amount so found due and also the mortgage money or the premium, as the case may be, the defendant shall put the plaintiff into possession of the land with the improvements thereon.
(2) If in such suit the court finds any sum of money due by the defendant to the plaintiff for rent, or otherwise in respect of the tenancy, the court shall set off such sum against the sum found due under sub-section (1), and shall pass a decree declaring as the amount payable to him on eviction the amount, if any, remaining due to the defendant after such set-off:
Provided that the court shall not set off any sum of money due for rent as aforesaid, if such sum is not legally recoverable.
(3) The amount of compensation for improvements made subsequent to the date up to which compensation for improvements has been adjudged in the decree and the re-valuation of an improvement, for which compensation has been so adjudged, when and in so far as such re-valuation may be necessary with reference to the condition of such improvement at the time of eviction as well as any sum of money accruing due to the plaintiff subsequent to the said date for rent, or otherwise in respect of the tenancy, shall be determined by order of the court executing the decree and the decree shall be varied in accordance with such order.
(4) Every matter arising under sub-section (3) shall be deemed to be a question relating to the execution of a decree within the meaning of sub-section
