164 Part II — <strong>Statutory</strong> <strong>Interpretation</strong><br />

the possibility <strong>of</strong> applying a purposive construction, to take account <strong>of</strong> any other applicable criteria<br />

also. <strong>The</strong> overriding object is to give effect to Parliament's intention, and this is unlikely to be to<br />

achieve the immediate purpose at no matter what cost. Contrary purposes <strong>of</strong> a more general nature<br />

may supervene, as in A-G <strong>of</strong> New Zealand v Ortiz [1982] 3 WLR 570. Here it was held at first<br />

instance that the phrase 'shall be forfeited' in the New Zealand Historic Articles Act 1962, s 12(2)<br />

was ambiguous, and that a purposive construction should be applied to decide whether forfeiture was<br />

automatic or depended upon actual seizure <strong>of</strong> the historic article in question. <strong>The</strong> decision was<br />

overruled on appeal because, though right as far as it went, it failed to take into account a further (and<br />

overriding) criterion. This was the rule <strong>of</strong> international law that limits the extra-territorial effect <strong>of</strong><br />

legislation relating to property rights.<br />

Non-purposive-and-literal construction<br />

In the sense used in English law, purposive construction is an almost invariable requirement. But a nonpurposive<br />

construction may be necessary, because unavoidable, where there is insufficient indication <strong>of</strong><br />

(a) what the legislative purpose is, or (b) how it is to be carried out. Thus in IRC v Hinchy [1960] AC<br />

748, 781 Lord Keith <strong>of</strong> Avonholm declined to apply a purposive construction <strong>of</strong> an income tax<br />

enactment because, as he said, the court could not take upon itself the task <strong>of</strong> working out an<br />

assessment in a different way to that indicated on a literal construction. For a further example see<br />

IRC v Ayrshire Employers Mutual Insurance Association Ltd [1946]<br />

1 All ER 637.<br />

Non-purposive construction may be necessary where the court considers a predictable construction<br />

(see p 153 above) is required. Apart from these cases, it is usually only where the literal meaning is<br />

too strong to be overborne that the court will apply a non- purposive-and-literal construction (eg<br />

Richards v MacBride (1881) 8QBD 119).<br />

Statements <strong>of</strong> purpose<br />

<strong>The</strong> search for the purpose <strong>of</strong> an enactment is sometimes assisted by an express statement on the<br />

lines <strong>of</strong>: '<strong>The</strong> purpose <strong>of</strong> [this enactment] is to remedy the defect in the law consisting <strong>of</strong> [description <strong>of</strong><br />

the mischief] by amending the law so as to [description <strong>of</strong> the remedy].' A statement <strong>of</strong> purpose (whether on<br />

these lines or not, and whether comprehensive or not) may be found either in the Act or in the<br />

judgment <strong>of</strong> a court devising the statement as an aid to construction (see Whitley v Stumbles [1930] AC<br />

544, 547; Haskins v Lewis [1931]<br />

2 KB 1, 14; Dudley and District Building Society v Emerson [1949] Ch 707, 715; Wallersteiner v<br />
