"(1) An occupational pension scheme which does not contain an equal treatment rule shall be treated as including one. (2) An equal treatment rule is a rule which relates to the terms on which - (a) persons become members of the scheme, and (b) members of the scheme are treated. (3) Subject to subsection (6), an equal treatment rule has the effect that where - (a) a woman is employed on like work with a man in the same employment, (b) a woman is employed on work rated as equivalent with that of a man in the same employment, or (c) a woman is employed on work which, not being work in relation to which paragraph (a) or (b) applies, is, in terms of the demands made on her (for instance under such headings as effort, skill and decision) of equal value to that of a man in the same employment, but (apart from the rule) any of the terms referred to in subsection (2) is or becomes less favourable to the woman than it is to the man, the term shall be treated as so modified as not to be less favourable."
"(4) Section 62 shall be construed as one withsection 1 of the Equal Pay Act 1970 (requirement of equal treatment for men and women in the same employment); and sections 2 and 2A of that Act (disputes and enforcement) shall have effect for the purposes of section 62 as if - (a) reference to an equality clause were to an equal treatment rule, (b) references to employers and employees were to the trustees or managers of the scheme (on the one hand) and the members, or prospective members of the scheme (on the other), (c) for section 2(4) there were substituted - '(4) No claim in respect of the operation of an equal treatment rule in respect of an occupational pension scheme shall be referred to an industrial tribunal otherwise than by virtue of subsection (3) above unless the woman concerned has been employed in a description or category of employment to which the scheme relates within the six months preceding the date of the reference', and (d) references toSection 1(2)(c) of the Equal Pay Act 1970 were to section 62(3)(c) of this Act. … (6) Section 62, so far as it relates to the terms on which members of a scheme are treated, is to be treated as having had effect in relation to any pensionable service on or after 17 th May 1990."
"Section 63(6) might appear to be fatal to [Mrs Carr's] claim in that the benefit she wants to buy-back would all have accrued before17 May 1990 . But the treatment of which she complains does not relate to pensionable service before that date: her service before that date was not pensionable, for she was not a member of the scheme. The mischief against which the subsection guards is bad treatment of members while they are members, or after they have become pensioners. However, the refusal to let [Mrs Carr] buy-back, … continued or recurred after17 May 1990 . That is the bad treatment of which [she] complains: it is an incident of her pensionable service after the relevant date."
