the EAT cast doubt on whether the rejection of a discrimination case based on 'colour' from the operation of the Race Relations Act 1976 s.54A was correct. 'Colour' is not specifically included in S.54A which requires an employer to disprove unlawful discrimination if a prima facie case is made of 'discrimination on grounds of race or ethnic or national origins'.
