"(1) An industrial tribunal shall not consider a complaint under section 54 unless it is presented to the tribunal before the end of the period of three months beginning when the act complained of was done.
"A person discriminates against another in any circumstances relevant for the purposes 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 ..."
"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) ... (b) ... (c) by dismissing him, or subjecting him to any other detriment."
"(1) A complaint may be presented to an industrial tribunal against an employer by any person (in this Part referred to as the complainant) that he was unfairly dismissed by the employer.
"Putting it quite shortly, it seems to us that the mischief which Parliament was intending to cover by those provisions was that of a person finding himself out of a job because of racial or other discriminatory grounds. If that be right (and it appears to us that it is), then the act complained of is the termination of employment and accordingly the effective date for considering when time starts to run is the date when the man finds himself out of a job rather than the date when he is given notice. Of course, the two may be the same as, in Dedman's case, when the notice and the dismissal occurred simultaneously. But in this case it was clear that the employment continued until 28 February and, in our judgment, the act referred to in section 68(1) was that of the termination of the employment. That occurred on 28 February and accordingly the application was brought within time.
"(1) An employee may present a complaint to an industrial tribunal on the ground that action has been taken against him by his employer in contravention of section 23.
"We are satisfied that for the purpose of applying the limitation provision in s. 24(2) it is necessary on the facts of this case to look at all the disciplinary decisions of which Mr Clark and Mr Havill wish to complain. These decisions include the determinations of the appeals. It is clear from s. 24(2) that a complaint may be made about more than one action by an employer and we do not consider that the decided cases concerning appeals where an employee has been dismissed provide any exact analogy."
