“Parts IVA and V of the Employment Rights Act 1996 .”
“(1) Subsection (2) applies in any proceedings in which a court determines whether a provision of primary legislation is compatible with a Convention right. (2) If the court is satisfied that the provision is incompatible with a Convention right, it may make a declaration of that incompatibility… (4) If the court is satisfied— (a) that the provision is incompatible with a Convention right, and (b) that (disregarding any possibility of revocation) the primary legislation concerned prevents removal of the incompatibility, it may make a declaration of that incompatibility… (6) A declaration under this section (‘a declaration of incompatibility’)— (a) does not affect the validity, continuing operation or enforcement of the provision in respect of which it is given; and (b) is not binding on the parties to the proceedings in which it is made.”
“Subsection (1) does not apply to an act if—(a) as the result of one or more provisions of primary legislation, the authority could not have acted differently; or (b) in the case of one or more provisions of, or made under, primary legislation which cannot be read or given effect in a way which is compatible with the Convention rights, the authority was acting so as to give effect to or enforce those provisions.”
“For present purposes it is sufficient to say that a meaning which departs substantially from a fundamental feature of an Act of Parliament is likely to have crossed the boundary between interpretation and amendment. This is especially so where the departure has important practical repercussions which the court is not equipped to evaluate. In such a case the overall contextual setting may leave no scope for rendering the statutory provision Convention-compliant by legitimate use of the process of interpretation. The boundary line may be crossed even though a limitation on Convention rights is not stated in express terms. Lord Steyn’s observations in RvA (No 2)[2002] 1 AC 45 , 68d-e, para 44 are not to be read as meaning that a clear limitation on Convention rights in terms is the only circumstance in which an interpretation incompatible with Convention rights may arise.”
“30. an unusual and far-reaching character. Section 3 may require a court to depart from the unambiguous meaning the legislation would otherwise bear. In the ordinary course the interpretation of legislation involves seeking the intention reasonably to be attributed to Parliament in using the language in question. Section 3 may require the court to depart from this legislative intention, that is, depart from the intention of the Parliament which enacted the legislation. The question of difficulty is how far, and in what circumstances, section 3 requires a court to depart from the intention of the enacting Parliament. The answer to this question depends upon the intention reasonably to be attributed to Parliament in enacting section 3.”
“34. It follows that, in applying national law, whether the provisions in question were adopted before or after the Directive, the national court called upon to interpret it is required to do so, as far as possible, in light of the wording and the purpose of the Directive in order to achieve the result pursued by the latter and thereby comply with the third paragraph of article 189 of the Treaty.”
“71. Again, “red, blue or green” cannot be read as meaning “red, blue, green or yellow”; the specification of three only of the four primary colours indicates a deliberate omission of the fourth (unless, of course, this can be shown to be an error). Section 3 cannot be used to supply the missing colour, for this would be not to interpret the statutory language but to contradict it.”
“121. When the court spells out the words that are to be implied, it may look as if it is “amending” the legislation, but that is not the case. If the court implies words that are consistent with the scheme of the legislation but necessary to make it compatible with Convention rights, it is simply performing the duty which Parliament has imposed on it and on others. It is reading the legislation in a way that draws out the full implications of its terms and of the Convention rights. And, by its very nature, an implication will go with the grain of the legislation. By contrast, using a Convention right to read in words that are inconsistent with the scheme of the legislation or with its essential principles as disclosed by its provisions does not involve any form of interpretation, by implication or otherwise. It falls on the wrong side of the boundary between interpretation and amendment of the statute.”
“such an interpretation would be incompatible with the underlying thrust of the legislation, or would not go with the grain of it, or would call for legislative deliberation, or would change the substance of a provision completely, or would remove its pith and substance, or would violate a cardinal principle of the legislation”
“so far as it is possible to do so.”
