Race discrimination: Victimiser must normally have had actual knowledge of protected act

In Ledeatte v London Borough of Tower Hamlets 26.6.00 EAT 739/99, the EAT holds that an employee claiming to have been victimised had, in order to establish the necessary causal link between the less favourable treatment she complained of and a previous complaint she had brought against her employer under the Race Relations Act, to show that the individuals who had mistreated her had actual knowledge of that protected act. Without such knowledge, it could not be shown that the less favourable treatment was "by reason that" the employee had done the protected act.
