In the case of a lease or sublease of land under this Act, if it is proved to the satisfaction of the Registrar that the lessor or sublessor or his or her transferee has re-entered upon the premises in strict conformity with the provisions for re-entry contained in the lease or sublease, or under the power of section 102(b), where the lease or sublease is under this Act, or that the lessee or sublessee has abandoned the leased premises and the lease, and that the lessor or sublessor or his or her transferee has thereupon re-entered upon and occupied the abandoned premises by himself or herself or tenants undisturbed by the lessee or sublessee, the Registrar may make an entry of that re-entry in the Register Book or in the Sublease Register, as the case may be, and the term for which the land was leased or subleased shall, upon that entry being made, determine and may be removed as an encumbrance from a certificate, but without prejudice to any action or cause of action which previously has been commenced or has accrued in respect of any breach or non-observance of any covenant expressed in the lease or sublease or by law declared to be implied in the lease or sublease.
