“1) Interpretation is the ascertainment of the meaning which the document would convey to a reasonable person having all the background knowledge which would reasonably have been available to the parties in this situation in which they were at the time of the contract. 2) The background was famously referred to by Lord Wilberforce as the “matrix of fact”, but this phrase is, if anything, an understated description of what the background may include. Subject to the requirement that it should have been reasonably available to the parties and to the exemption to be mentioned next, it includes absolutely anything which would have affected the way in which the language of the document would have been understood by a reasonable man … 4) The meaning which a document … would convey to a reasonable man is not the same thing as the meaning of its words … the meaning of the document is what the parties using those words against the relevant background would reasonably have been understood to mean … 5) The “rule” that words should be given their “natural and ordinary meaning” reflects the commonsense proposition that we do not easily accept that people have made linguistic mistakes, particularly in formal documents. On the other hand, if one would nevertheless conclude from the background that something must have gone wrong with the language, the law does not require Judges to attribute to the parties an intention which they plainly could not have had.”

“The difficulty in the application of these conceptions” continued Dixon J “is to distinguish the matters fundamental or cardinal to the prior decision or judgment, or necessarily involved in it as its legal justification or foundation, from matters which, even though actually raised and decided as being in the circumstances of the case the determining considerations, yet are not in point of law the essential foundation or ground work to the judgment”, “In order to make this distinction one has to inquire whether the determination was so fundamental to the decision that the latter cannot stand without it. Even where this condition is met, it is suggested by Dixon J that there is another test to pass, viz whether the determination is the “immediate foundation” of the decision or merely “a proposition collateral or subsidiary only ie. no more than part of the reasoning supporting the conclusion”
