'First, the words are to be given their ordinary meaning. They are not to be given some other meaning simply because their object is to frustrate legitimate tax avoidance devices ...Secondly ... one has to look merely at what is clearly said. There is no room for any intendment. There is no equity about a tax. There is no presumption as to tax. Nothing is to be read in, nothing is to be implied. One can only look fairly at the language used ... Thirdly, the object of the construction of a statute being to ascertain the will of the legislature it may be presumed that neither injustice nor absurdity was intended. If therefore a literal interpretation would produce such a result, and the language admits of an interpretation which would avoid it, then such an interpretation may be adopted. Fourthly, the history of an enactment and the reasons which led to its being passed may be used as an aid to its construction.'
'To apply the words literally is to defeat the obvious intention of the legislation and to produce a wholly unreasonable result. To achieve the obvious intention and produce a reasonable result we must do some violence to the words. This is not a new problem, though our standard of drafting is such that it rarely emerges. The general principle is well settled. It is only where the words are absolutely incapable of a construction which will accord with the apparent intention of the provision and will avoid a wholly unreasonable result, that the words of the enactment must prevail.'
'If it is right that, in order to avoid imputing to Parliament an intention to produce an unreasonable result, we are entitled, and indeed bound, to discard the ordinary meaning of any provision and adopt some other possible meaning which will avoid that result, then what I am looking for in examining the obscure provision at the end of [the relevant section] is not its ordinary meaning (if it has one) but some possible meaning which will produce a reasonable result. I think that the interpretation which I have given is a possible interpretation and does produce a reasonable result, and therefore I adopt it.'
'Vinelott J commented [[1991] STC 455 at 462]: "As a matter of first impression, on a first reading of s 72 it is natural to read sub-s (4) as one of a group of subsections dealing only with cases [of small distributions] ..." However, as Scott LJ went on to say (at 707): '
'The approach indicated in these passages justifies, in my judgment, implying into s 72(4) the natural limitation as to its scope that would correspond with the obvious intention of the legislature, namely, that the subsection should apply only to cases where the amount of the distribution was, in comparative terms, small ... In my judgment, it would be a very rare case in which effect could not be given by a permissible process of interpretation to the apparent intention of the legislature. At all events, in the present case I cannot accept that there is any reason why the limitation to which I have referred should not be implied, thereby giving effect to the presumed, the apparent, intention of the legislature.'
"It has long been established that the role of the courts in construing legislation is not confined to resolving ambiguities in statutory language. The court must be able to correct obvious drafting errors. In suitable cases, in discharging its interpretative function the court will add words, or omit words or substitute words….This power is confined to plain cases of drafting mistakes. The courts are ever mindful that their constitutional role in this field is interpretative. They must abstain from any course which might have the appearance of judicial legislation. A statute is expressed in language approved and enacted by the legislature. So the courts exercise considerable caution before adding or omitting or substituting words. Before interpreting a statute in this way the court must be abundantly sure of three matters: (1) the intended purpose of the statute or provision in question; (2) that by inadvertence the draftsman and Parliament failed to give effect to that purpose in the provision in question; and (3) the substance of the provision Parliament would have made, although not necessarily the precise words Parliament would have used, had the error in the Bill been noticed. The third of these conditions is of crucial importance. Otherwise any attempt to determine the meaning of the enactment would cross the boundary between construction and legislation. Sometimes, even when these conditions are met, the court may find itself inhibited from interpreting the statutory provision in accordance with what it is satisfied was the underlying intention of Parliament. The alteration in language may be too far-reaching. In Western Bank Ltd. v. Schindler[1977] Ch 1 , 18, Scarman L.J. observed that the insertion must not be too big, or too much at variance with the language used by the legislature. Or the subject matter may call for a strict interpretation of the statutory language, as in penal legislation. None of these considerations apply in the present case. Here, the court is able to give effect to a construction of the statute which accords with the intention of the legislature.” 34. In the Court of Appeal decision in Pollen Estate Trustee Ltd v HMRC[2013] EWCA Civ 753 , a case concerned with stamp duty land tax exemption for charities, the Court agreed with Lord Reid and read in words into the legislation to correct drafting mistakes. The relief was not available to the charity on a pure construction of the legislation because it purchased land with third parties and so acquired an undivided share in the land. The Court thought that was anomalous and agreed with the Upper Tribunal that there was not any identifiable policy which would have led Parliament to exclude exemption in the circumstances under appeal. Lewison LJ in giving the judgement of the Court said: "23….If Parliament did not deliberately exclude exemption in the cases under appeal, then it seems obvious that, if it did so, it did so by mistake" 35. Lewison LJ then sought to identify what additional wording should be read into the legislation to ensure the legislation matched Parliament's intentions; "46 I agree with the Upper Tribunal that the mere substitution of plural for singular does not solve the problem. But I do not agree that to read the paragraph as applying where the purchasers include a charity goes "beyond any process of construction"…in my judgment the process of construction could allow the court to read "the purchaser" as "one of the purchasers" if that reading is necessary to make sense of the statute as a whole. 47 However, I do not favour that reading. I do not favour it because its consequence would appear to be that the whole land transaction would then be exempt from SDLT, which cannot have been Parliament's intention. The reading of paragraph 1(1) which I would favour is: "
