A tenant who, in proceedings to enforce a right of re-entry or forfeiture or a right to damages in respect of a failure to comply with any terms of his lease, applies for relief under section 16 of the M1Landlord and Tenant Act 1954 is not thereby precluded from making a claim to acquire a new lease under this Chapter; but if he gives notice under section 16(2) of that Act (under which the tenant is relieved from any order for recovery of possession or for payment of damages, but the tenancy is cut short), any notice given by him under section 42 with respect to property comprised in his lease shall be of no effect or, if already given, shall cease to have effect.

Sub-paragraph (1) shall apply in relation to proceedings relating to a superior tenancy with the substitution for the references to section 16 and to section 16(2) of the Landlord and Tenant Act 1954 of references to paragraph 9 and to paragraph 9(2) of Schedule 5 to that Act.
