(4) Within 30 days of personal service by the landlord of a written request, or, at the landlord's option, a notice of termination of tenancy under Section 37.9(a)(8), the tenant must submit a statement, with supporting evidence, to the landlord if the tenant claims to be a member of one of the classes protected by Section 37.9(i). The written request or notice shall contain a warning that a tenant's failure to submit a statement within the 30 day period shall be deemed an admission that the tenant is not protected by Section 37.9(i). The landlord shall file a copy of the request or notice with the Rent Board within 10 days of service on the tenant. A tenant's failure to submit a statement within the 30 day period shall be deemed an admission that the tenant is not protected by Section 37.9(i). A landlord may challenge a tenant's claim of protected status either by requesting a hearing with the Rent Board or, at the landlord's option, through commencement of eviction proceedings, including service of a notice of termination of tenancy. In the Rent Board hearing or the eviction action, the tenant shall have the burden of proof to show protected status. No civil or criminal liability under Section 37.9(e) or (f) shall be imposed upon a landlord for either requesting or challenging a tenant's claim of protected status.
(5) This Section 37.9(i) is severable from all other sections and shall be of no force or effect if any temporary moratorium on owner/relative evictions adopted by the Board of Supervisors after June 1, 1998 and before October 31, 1998 has been invalidated by the courts in a final decision.
