Nothing contained herein shall limit any rights or remedies a tenant may have under a lease.
No landlord shall be liable to any penalty under section 5 of this act nor any lease termination by a tenant under section 6 of this act, for any lease provision in violation of section 6 of this act where the proposal to include such lease provision originated from the tenant and not such landlord.
