Section 84A of the Housing Act 1985 (“the Act”) provides for a new, absolute, anti-social behaviour ground for possession of a dwelling that is the subject of a secure tenancy. Section 85ZA of the Act provides secure tenants of local housing authorities and housing action trusts with a right to request a review of a landlord’s decision to seek possession under section 84A. The landlord must review the decision if the tenant requests it.
