The question the court actually asks
Interpretation is objective. The court asks what a reasonable person, with all the background knowledge reasonably available to the parties at the time, would have understood the contract to mean. It is not looking for what either side privately intended, but for the meaning the words would convey to a reasonable reader of the whole document.
That single question governs everything else. The tools the court uses are just ways of answering it.
Wood v Capita: the governing framework
Wood v Capita Insurance Services Ltd [2017] UKSC 24 is the Supreme Court's definitive statement on interpretation. It resolved a perceived tension between two earlier cases - Rainy Sky SA v Kookmin Bank [2011] UKSC 50, which leaned on business common sense, and Arnold v Britton [2015] UKSC 36, which stressed the primacy of the language - by confirming that they are not in conflict.
Lord Hodge held that textualism and contextualism are complementary tools, not competing paradigms. Interpretation is one unitary, iterative exercise: you test each rival reading against the rest of the contract and its commercial consequences, and it does not matter whether you start from the words or the background, so long as you balance both.
Lord Hodge's principles in practice
Several points follow. The exercise is iterative: each suggested meaning is checked against the other provisions and the commercial outcome it produces. The quality of drafting matters: a sophisticated, professionally negotiated contract is interpreted principally on its text, while an informal, brief document leaves more room for the factual matrix.
And the court keeps two cautions in mind: a provision may be a deliberate compromise, or simply a term the parties could not make more precise, and one side may have agreed to something that turned out badly. Neither is a reason to depart from the natural meaning.
Why this favours the words you used
For most commercial agreements - drafted by professionals, heavily negotiated - the practical effect is that the text leads. You should not assume a court will reach for commercial common sense to rescue you from wording that, read naturally, does not say what you now wish it said.
That is exactly what happened in Wood v Capita: a carefully drafted indemnity was given its plain meaning even though the other side argued a broader reading made more commercial sense. The words won.
What it means for drafting and review
If interpretation turns on the words, then the words are where the work is. Define key terms precisely, make sure each clause is consistent with the rest of the contract, and read a definition together with every operative clause that uses it.
In review, the highest-value checks are internal consistency and definitional precision: a term that is clear on its own but contradicts an operative clause is a dispute waiting to happen.
Use at the desk
Practical checklist
- Expect an objective reading: what a reasonable person with the background knowledge would understand the words to mean.
- Treat textual and contextual analysis as one exercise - test each reading against the whole contract and its commercial result (Wood v Capita [2017] UKSC 24).
- Do not rely on business common sense to override clear language in a sophisticated contract (Arnold v Britton [2015] UKSC 36).
- Remember a vague term may be read as a deliberate compromise, not an invitation for the court to help you.
- In review, prioritise internal consistency and definitional precision over surface wording.
