Determination of tenancy

(1) Upon the conviction of the tenant, lessee or occupier of any premises of knowingly permitting the premises, or any part thereof, to be used as a brothel, the landlord or lessor shall be entitled to determine the lease or other contract but without prejudice to the rights or remedies of any party to such lease or contract accrued before the date of such determination. (2) If the landlord or lessor should so determine the lease or other con- tract of tenancy, the court which has convicted the tenant, lessee or occupier shall have power to make a summary order for delivery of possession to the landlord or lessor. (3) If the landlord or lessor, after a conviction for an offence as described in subsection (1) of this section has been brought to his notice, fails to exercise his rights under subsection (1) of this section and subsequently during the subsistence of the lease or contract any such offence is again committed in respect of the premises, the landlord or lessor shall be deemed to have knowingly aided or abetted the commission of the offence, unless he proves that he has taken all reasonable steps to prevent the recurrence of the offence. (4) Where a landlord or lessor determines a lease or other contract under the powers conferred by this section and subsequently grants another lease or enters into another contract of tenancy to, with or for the benefit of the same person without causing to be inserted in the lease or contract all reasonable provisions for the prevention of a recurrence of any such offence as aforesaid, he shall be deemed to have failed to exercise his rights under this section, and any such offence as aforesaid committed during the subsistence of the subsequent lease or contract shall be deemed, for the purposes of this section, to have been committed during the subsistence of the previous lease or contract.
