Will a court decline to enforce contractual wording because its commercial result appears irrational?
A party bound by an unwelcome literal reading often argues that the result is commercial nonsense. Whether a court will correct the words, or hold the party to them, is governed by a settled and carefully limited approach to interpretation.
Only in a narrow way: the courts enforce the meaning a reasonable reader takes from the words, and will correct the language only where the drafting contains an obvious error; commercial nonsense alone does not free a party from clear wording it agreed
Only in a narrow way. A court enforces the meaning a reasonable person would take from the words, read with the background reasonably available to the parties, not what one side privately intended. Where the drafting plainly fails to express the intended bargain, so that a reasonable reader would see both the mistake and what was plainly meant, the court may correct the wording by construction; the House of Lords did so where a literal formula gave the seller a windfall out of proportion to the deal. That power is tightly limited. The modern cases stress that clear words are not easily displaced, and that commercial common sense must not be used to undervalue the language the parties chose. A bad bargain is not a drafting mistake, and the court will not rewrite a contract because one side did badly out of it. The words carry the risk.
| Starting point | The meaning a reasonable reader takes from the words, against the background |
| Correction | Available only where the drafting has plainly failed to express the bargain |
| Clear words | Not easily displaced; commercial sense cannot undervalue the language |
| Bad bargain | Not a drafting mistake; the court will not rewrite the contract |
| Negotiations | Pre-contractual negotiations are generally inadmissible |
The problem
A party makes a bad bargain. The words of the contract, read literally, give the other side a windfall out of all proportion to anything the parties can have intended. Can the disappointed party escape the words on the ground that the result is commercial nonsense, or is it bound by what it signed? The courts have a settled, and carefully limited, answer.
The reasonable-reader test
The starting point is that a court enforces the intention the parties expressed in their words. It reads the contract as a reasonable person would, with all the background knowledge reasonably available to the parties at the time, and gives the words the meaning that reader would take from them. What the parties privately intended, but did not put in the contract, does not count. This is the approach the House of Lords set out in Investors Compensation Scheme Ltd v West Bromwich Building Society: the meaning is assessed objectively by asking how the contractual words would be understood in their admissible setting, and the words are read not in a vacuum but against that background.
Correcting an obvious mistake
A land sale contract set an additional payment to the seller by a formula. Read literally, the formula produced a figure far larger than the structure of the deal could have intended: the seller claimed over nine million pounds where the developer's reading gave about five and a half million. The House of Lords held for the developer. Where the drafting plainly fails to express the intended bargain, the court need not ascribe to the parties a purpose they plainly could not have had, and may correct the wording by construction to give the sensible meaning. The House also reaffirmed that the parties' pre-contractual negotiations are not admissible to construe the contract.
The limit on commercial sense
That power is tightly bounded, and the modern cases stress the limit. The natural meaning of the words is not easily displaced: courts do not readily accept that formal drafting can contain errors of expression. Commercial common sense and background cannot be used to depart from language that is clear, and the clearer the words, the harder it is to argue that they do not mean what they say. The Supreme Court made the point in Arnold v Britton, warning against using business common sense to undervalue the words the parties chose. A bad bargain is not the same as a drafting mistake, and a court will not rewrite a contract merely because one side did badly out of it.
A narrow escape route
The result is a narrow escape route, not a general one. Where the language is clear it governs, even if the outcome is hard on one party. Only where the words contain an obvious drafting failure, so that a reasonable reader would see both the mistake and what was plainly meant, will a court correct them. The lesson for both sides is that the words carry the risk: a party that signs unclear or ill-considered wording cannot count on a court to save it by appealing to commercial sense.
Practical steps
Draft to the reasonable-reader test. Say what you mean in the words, because the words, read against the background, will govern.
Do not rely on a court to rescue you from a bad bargain. Commercial nonsense alone will not displace clear language.
The correction route is narrow. It works only where the words contain an obvious drafting failure and the intended meaning is plain.
Do not expect pre-contract negotiations to be admitted to change the meaning. They are generally inadmissible.
Check formulas and figures before signing. A literal result out of proportion to the deal is exactly the wording that leads to dispute.
Where a term is important, make its meaning explicit, so its natural meaning is the meaning you intend.
