Notable Cases

Southwark LBC v Ibidun 19 October 2017. The High Court found that the Circuit Judge at trial had correctly applied Islington LBC v Boyle [2011] EWCA Civ 1450 and dismissed the local authority's appeal as no more than a disagreement with the facts.

R (Hakima Alemi) v Westminster City Council [2015] EWHC 1765 (Admin)
As a pupil, Sebastian assisted Tim Baldwin (led by Jan Luba QC). The local authority's denial of bidding rights for the first 12 months to those to whom it accepted a homelessness duty was found to be unlawful.
