In Mayor and Burgesses of the London Borough of Lewisham v Malcolm [2008] UKHL 43, the House of Lords have overruled the Court of Appeal's decision in Clark v TDG Ltd t/a Novacold, making potentially major changes to the law on disability-related discrimination. Although the case, under Part III of the DDA 1995, concerned a housing authority's decision to evict a schizophrenic tenant who had unlawfully sublet his flat, the decision looks set to have far-reaching implications for employment cases under Part II of the DDA.
