"98 General (1) In determining for the purposes of this Part whether the dismissal of an employee is fair or unfair, it is for the employer to show- (a) the reason (or, if more than one, the principal reason) for the dismissal, and (b) that it is either a reason falling within subsection (2) or some other substantial reason of a kind such as to justify the dismissal of an employee holding the position which the employee held. (2) A reason falls within this subsection if it- (a) relates to the capability or qualifications of the employee for performing work of the kind which he was employed by the employer to do, (b) relates to the conduct of the employee, (c) is that the employee was redundant, or (d) is that the employee could not continue to work in the position which he held without contravention (either on his part or on that of his employer) of a duty or restriction imposed by or under an enactment. (4) Where the employer has fulfilled the requirements of subsection (1), the determination of the question whether the dismissal is fair or unfair (having regard to the reason shown by the employer)- (a) depends on whether in the circumstances (including the size and administrative resources of the employer's undertaking) the employer acted reasonably or unreasonably in treating it as a sufficient reason for dismissing the employee, and (b) shall be determined in accordance with equity and the substantial merits of the case."
"1 Racial Discrimination (1) A person discriminates against another in any circumstances relevant for the purpose of any provision of this Act if- (a) on racial grounds he treats that other less favourably than he treats or would treat other persons if; or (b) he applies to that other a requirement or condition which he applies or would apply equally to persons not of the same racial group as that other but- (i) which is such that the proportion of persons of the same racial group as that other who can comply with it is considerably smaller than the proportion of persons not of that racial group who can comply with it; and (ii) which he cannot show to be justifiable irrespective of the colour, race, nationality or ethnic or national origins of the person to whom it is applied; and (iii) which is to the detriment of that other because he cannot comply with it. 4 …Applicants and employees (2) It is unlawful for a person, in the case of a person employed by him at an establishment in Great Britain, to discriminate against that employee- (a) in the terms of employment which he affords him; or (b) in the way he affords him access to opportunities for promotion, transfer or training, or to any other benefits, facilities or services, or by refusing or deliberately omitting to afford him access to them; or (c) by dismissing him, or subjecting him to any other detriment."
