(1) Notwithstanding anything contained in any law for the time being in force, and in the absence of agreement to the contrary by the tenant, every landlord shall be bound to keep the premises in good and tenantable repair.
     (2) If the landlord neglects or fails to make within a reasonable time, after notice in writing any repairs which he is bound to make under sub-section (1), the tenant may make the same himself and deduct the expenses of such repairs from the rent or otherwise recover them from the landlord:
     Provided that the amount so deducted or recoverable in any year shall not exceed one-twelfth of the rent payable by the tenant for that year.
     (3) Where any repairs without which the premises are not habitable or useable except with undue inconvenience are to be made and the landlord neglects or fails to make them after notice in writing, the tenant may apply to the court for permission to make such repairs himself, provided that the cost of such repairs does not exceed rent for a period of two years payable by that tenant and where such repairs are made with the permission of the court, the limitation as to the amount deductible or recoverable as provided in sub-section (2) shall not apply.
