JUDGEMENT :- The landlords within the meaning of the Tamil Nadu Buildings (Lease and Rent Control) Act (Act 18 of 1960) hereinafter referred to as 'the Act' are the petitioners in this revision. The respondent herein is the tenant within the meaning of the Act.

The tenant contested the petition of the landlords and yet, the Controller countenanced the case of the landlords and ordered eviction of the tenant. The tenant appealed and the Appellate Authority discountenanced the case of the landlords on two grounds, namely, (1) the premises demised consisted of two door numbers and single petition for eviction would not lie and (2) the landlords have not proved their means to undertake the work of demolition and reconstruction. The other points have been found in favour of the landlords by the appellate authority; the appellate authority found that the landlords are armed with a sanctioned plan from the corporation of Madras for the work of demolition and reconstruction and the existing condition
