London Borough of Islington v Secretary of State for Housing, Communities and Local Government and Maxwell Estates  EWCH 2691 –
11.At the Inquiry, in examination in chief, Mr Abbasi accepted that there was an intention to improve the quality of the flat to enable the rent to be increased and that that justified the subsequent tenant, Miss Migliore being charged more rent. It seems to me that, despite the break in occupation, this amounts to clear evidence of a continuation of the residential use and intention to permit occupation of the unit again, upon completion of the improvement works and thus to further the breach. This was therefore a period during which the unauthorised use continued.”
23.The Council submitted that the Inspector erred in failing to apply the approach to section 171B(2) TCPA 1990 set out by the Court of Appeal in Thurrock Borough Council v Secretary of State for the Environment  EWCA Civ 226,  JPL 1278 (upholding the judgment of the High Court, reported at  JPL 1388) and Swale v Borough Council v Secretary of State for the Environment  EWCA Civ 1568,  JPL 886. In deciding whether or not there had been continuous use, the Inspector wrongly applied a presumption of continuance, and took into account impermissible factors such as Maxwell Estate’s intentions and whether the basement was habitable.
