15(1)The provisions of this paragraph shall have effect where the landlord is entitled to make an application under sub-paragraph (1) of paragraph 13 above but does not obtain an order under that paragraph or paragraph 14 above.
(2)If at the expiration of the period within which an application under paragraph 13(1) above may be made the landlord has not made such an application, the landlord’s notice to resume possession, and anything done in pursuance thereof, shall cease to have effect.
(3)If before the expiration of the period mentioned in sub-paragraph (2) above the landlord has made an application under paragraph 13(1) above but the result of the application, at the time when it is finally disposed of, is that no order is made, the landlord’s notice to resume possession shall cease to have effect.
(4)In any case where sub-paragraph (3) above applies, then, if within the period of one month beginning on the date that the application to the court is finally disposed of the landlord serves on the tenant a landlord’s notice proposing an assured tenancy, the earliest date which may be specified in the notice as the date of termination shall, notwithstanding anything in paragraph 4(1)(b) above, be the day following the last day of the period of four months beginning on the date of service of the subsequent notice.
(5)The reference in sub-paragraphs (3) and (4) above to the time at which an application is finally disposed of shall be construed as a reference to the earliest time at which the proceedings on the application (including any proceedings on or in consequence of an appeal) have been determined and any time for appealing or further appealing has expired, except that if the application is withdrawn or any appeal is abandoned the reference shall be construed as a reference to the time of withdrawal or abandonment.
(6)A landlord’s notice to resume possession may be withdrawn at any time by notice in writing served on the tenant (without prejudice, however, to the power of the court to make an order as to costs if the notice is withdrawn after the landlord has made an application under paragraph 13(1) above).
(7)In any case where sub-paragraph (6) above applies, then, if within the period of one month beginning on the date of withdrawal of the landlord’s notice to resume possession the landlord serves on the tenant a landlord’s notice proposing an assured tenancy, the earliest date which may be specified in the notice as the date of termination shall, notwithstanding anything in paragraph 4(1)(b) above, be the day following the last day of the period of four months beginning on the date of service of the subsequent notice or the day following the last day of the period of six months beginning on the date of service of the withdrawn notice, whichever is the later.
