this means that as long as a tenant remains in business occupation of its premises after the expiry of the contractual term of the lease, the tenancy will not terminate and will continue under the provisions of the act. if they are no longer in business occupation of the premises then the security of tenure provisions will not apply and the lease will come to an end on the expiry of the term. a tenancy at will is a personal arrangement between landlord and tenant where the parties have agreed (either expressly or impliedly) that the tenancy can be terminated by either party at any time.
