Summarize the following court judgment. Civil Appeal No. 150 of 1963. Appeal by special leave from the judgment and decree dated January 9	 1962 of the Calcutta High Court in Appeal from Original Decree No. 48 of 1961. N.C. Chatterlee	 R.K. Garg	 S.C. Agarwal	 M.K. Rarnatnurthi and D.P. Singh	 for the appellant. M.C. Setalvad and B.P. Maheshwari	 for the respondent. October 10	 1963. The Judgment of the Court was delivered by RAGHUBAR DAYAL J. Raj Kishore Tewari	 appellant in this appeal by special leave	 was occupying certain premises as sub tenant of Susil Chandra Banerjee	 under a registered lease dated April 10	 1954. His tenancy commenced from April 1	 1954. The rent fixed was Rs. 220 per mensem. Subsequent 123 ly it was reduced to Rs. 205 by an agreement dated June 9	 1954. The tenancy was monthly. Susil Chandra Banerjee was the tenant of Govindaram Bhansali from September 15	 1943	 at a monthly rental of Rs. 153 plus certain other charges. On June 16	 1955	 the landlord obtained a decree of ejectment against Susil Chandra Banerjee. In view of sub section (2) of section 13 of the West Bengal Premises Rent Control (Temporary Provisions) Act	 1950 (Act XVII of 1950)	 hereinafter called the Act	 the appellant became the tenant of the landlord after the determination of the tenancy of Susil Chandra Banerjee. On March 19	 1957	 the land lord respondent gave a notice to the appellant asking him to deliver possession of the premises on the expiry of the last day of April 1957	 on the ground that he	 being the statutory tenant	 had not paid rents to him since June 16	 1955	 and	 as such	 was not entitled to any protection under the West Bengal Premises Tenancy Act	 1956 (Act XII of 1956). Subsequently	 on June 10	 1957	 the respondent instituted the suit for ejectment of the appellant from the premises. The suit was resisted by the appellant on various grounds. His defence was however struck off due to certain default. Ultimately	 the suit was decreed on December 15	 1959. An appeal to the High Court was unsuccessful. The High Court refused to give leave to appeal to this Court. Thereafter	 the appellant obtained special leave from this Court and filed the appeal. The only point urged for the appellant is that the notice of ejectment dated March 19	 1957	 was invalid in view of the fact that under the law the notice must be to require the appellant to deliver possession on the expiry of the month of tenancy	 that the tenancy was from the 16th of a month as the decree for ejectment against the tenant of the first degree was passed on June 16	 1955	 and that this notice required the delivery of possession on the expiry of the last day of April. We may say that this point was not raised in the written statement. It was however allowed to be raised in the appellate Court but was repelled. 124 The only point to determine in this appeal is the date from which the tenancy of the appellant vis a vis the respondent commenced. The relevant portion of sub s.(2) of section 13 of the Act is: "(2) Where any premises or any part thereof have been or has been sub let by 'a tenant of the first degree ' or by a tenant inferior to a tenant of the first degree '	 as defined in explanation to sub section (1)	 and the sub lease is binding on the landlord of such last mentioned tenant	 if the tenancy of such tenant in either case is lawfully determined otherwise than by virtue of a decree in a suit obtained by the landlord by reason of any of the grounds specified in clause (h) of the proviso to sub section (1) of section 12	 the sub lessee shall be deemed to be a tenant in respect of such premises or part	 as the case may be	 holding directly under the landlord of the tenant whose tenancy has been determined	 on terms and conditions on which the sub lessee would have held under the tenant if the tenancy of the latter had not been so determined. " There is nothing in these provisions which should persuade us to hold	 as urged for the appellant	 that the sub tenant becomes a tenant of the landlord from the date on which the tenancy of the tenant against whom a decree for ejectment is passed is determined. The provisions only lay down that the sub tenant would become the tenant of the landlord if the tenancy in chief is determined lawfully. On the other hand	 this sub section lays down that the subtenant would be tenant on the terms and conditions on which the sub lessee would have held under the tenant if the tenancy of the tenant had not been determined. This means that the terms and conditions of the tenancy between the erstwhile sub tenant and the landlord continue to be the same which were the terms and conditions of the sub tenancy. Such terms and conditions of the tenancy in the case of the appellant were that he was to be a monthly tenant on the payment of a certain rent and that his tenancy was to 125 commence from the first day of April 1954. It is clear therefore that his tenancy was by the calendar month. It commenced on the first day of the month and expired on the last day of the month. This period of monthly tenancy was in no way affected by the provisions of sub section (2) of section 13 whose effect was simply this that the sub tenant instead of being sub tenant of the tenant who had been ejected	 got a direct connection with the landlord and became his tenant in chief or	 as the Act describes	 tenant in the first degree. The statutory provision just brought about a change in the landlord of the sub tenant. The proprietor landlord took the place of the tenantin chief from whom the sub tenant had secured the tenancy. We are therefore of opinion that the High Court was right in rejecting the contention of the appellant with respect to the invalidity of the notice for ejectment dated March 19	 1957. The result is that the appeal fails and is dismissed with costs. Appeal dismissed.

The appellant was a sub tenant of S on a monthly basis commencing from April 1	 1954. S was the tenant of the Respondent from September 15	 1943 on a monthly rental. On June 16	 1955	 the respondent obtained a decree of ejectment against section In view of sub s(2) of section 13 of the West Bengal Premises Rent Control (Temporary Provisions) Act	 1950	 the appellant became the tenant of the respondent after the determination of the tenancy of section The respondant gave a notice to the appellant asking him to deliver possession of the premises on the expiry of the last day of April 122 1957	 since he being a statutory tenant had not paid rent since June 16	 1955. The respondant instituted a suit for ejectment	 which was decreed	 and an appeal to the High Court by the appellant was unsuccessful. On appeal by special leave	 it was contended that the notice was invalid for under the law the notice must be to require the appellant to deliver possession on the expiry of the month of tenancy	 that the tenancy was from the 16th of a month as the decree for ejectment against S was passed on June 16	 1955 and that this notice required the delivery of possession on the expiry of the last day of April. Held: The contention was untenable and rightly rejected by the High Court. The provisions of Sub section (2) of section 13 of the West Bengal Rent Control (Temporary Provisions) Act	 1950 only lay down that the sub tenant would become the tenant of the landlord if the tenancy in chief is determined	 on the same terms and conditions on which the sub lessee would have held under the tenant if the tenancy of the tenant had not been determined. This means that the terms and conditions of the tenancy between the erstwhile sub tenant and the landlord continue to be the same which were the terms and conditions of the sub tenancy. The period of monthly tenancy commencing from the first of the month and expiring on the last day of the month	 was in no way affected by the provisions of Sub section (2) of section (13) whose effect was simply that the sub tenant instead of being sub tenant of the tenant who had been ejected	 got a direct connection with the landlord and became his tenant in chief.
