Surinder Singh, J.

1. This Revision Petition arises out of concurrent decision of two Rent Control Authorities. The respondent Landlady filed an application for eviction of the petitioner from the premises in dispute which is mentioned in the ejectment application "premises marked L in green colour in the site plan attached." The boundaries of the disputed property have also been mentioned. According to the case of the respondent, the property in question which was a part of Khasra No. 14(sic)7, originally belonged to Dr. Ramesh Chander who had let out the same to the petitioner at a monthly rent of Rs. 10/- and at the time of the said lease, the petitioner was permitted to construct the shop as shown in green colour in the plan A3. The property was later on purchased by the respondent from Dr. Ramesh Chander and she had, thus, become the landlady. The ejectment of the petitioner was sought on two grounds, namely, default in payment of arrears of rent and material impairment of the value and utility of the premises caused by the construction of a new room along with an incomplete Bala Khana. The ejectment application was resisted by the petitioner and the Rent Controller fr
