Religious discrimination: Harassment based on third party's religion

In Saini v All Saints Haque Centre and others EAT/0227/08, the EAT held that, where a tribunal found on the facts that the employer had mistreated an employee in order to target his colleague on the grounds of the latter's religion, the tribunal erred in finding that the mistreatment was not unlawful because it was not based on the employee's own religion.
