Misrepresentation in business contracts, what counts, when the Australian Consumer Law protects your business, and what remedies a court can order

A supplier tells you their packaging line turns out 40,000 units a month. The vendor of an online business shows you a customer list with 500 names on it. A software vendor confirms the reporting features you need are live, not on a roadmap. You sign on the strength of statements like these, and months later discover the line runs at half that rate, half the customers have not bought in over a year, and the feature is still in development. When a false pre-contract statement helped persuade you into a deal, Australian law gives you options. If you are the one who made the statement, it gives the other side options against you.

What makes a statement a misrepresentation

A misrepresentation is a false statement, or conduct that conveys something false, made before a contract is entered into, that played a real part in persuading the other party to sign. Four elements have to be present:

A statement or conduct: Misrepresentations usually live in words: a pitch, an email, a proposal, a meeting or a phone call. But conduct can misrepresent too, such as presenting documents that leave out the very thing that changes their meaning.
Made before the contract: Misrepresentation is a pre-contract problem. It arises during negotiation, before the deal is formed. The statement does not need to be repeated in the written agreement, and frequently is not, which is why it catches businesses off guard.
False or misleading: The statement must be untrue, or true in a way that still misleads the reasonable reader.
Relied on: The statement must have induced the contract, meaning it was a real reason the party signed, not a passing remark they never acted on.

The High Court's decision in Krakowski v Eurolynx Properties Ltd (1995) 183 CLR 563 shows the elements at work in a commercial deal. The purchasers were buying a commercial property as an investment, attracted by a lease that appeared to show a strong tenant paying $156,000 a year in rent. What the vendor had not revealed was a separate agreement giving that tenant a rent-free period and a $156,000 fit-out payment, which changed the real return on the investment. The High Court found the purchasers were induced to enter the contract by conduct that was fraudulent and, under the then s 52 of the Trade Practices Act 1974 (Cth), misleading. The case is also a reminder that in Australia fraud must be pleaded distinctly and with particularity, and clearly proved.

The three kinds of misrepresentation, and why the label matters

Australian law draws a distinction between three kinds of misrepresentation. The distinction matters because it affects both the remedies available and the difficulty of proving the claim:

Innocent misrepresentation: The maker honestly believed the statement was true, with no intention to deceive. A seller who repeats figures supplied by their bookkeeper, genuinely assuming they are correct, is the typical shape. There is no fraud and no carelessness, but the statement can still be false and still induce the contract.
Negligent misrepresentation: The maker was careless, and made the statement without reasonable grounds for believing it was true. A supplier who promises that a product meets Australian standards without checking the certification or testing requirements is the classic example. At common law, this kind of claim also requires the maker to owe the recipient a duty of care, and the recipient to prove the maker fell short of the standard.
Fraudulent misrepresentation: The maker knew the statement was false, or was recklessly indifferent to whether it was true, and made it to induce the contract. Inflating sales results, or hiding a known defect to secure a higher price, are the obvious cases. This is the most serious category, the hardest to prove, and commercially the most damaging to be accused of, because fraud allegations travel beyond the dispute itself.

The practical point is that most commercial claims are pleaded under the Australian Consumer Law instead of the common law categories, because the statutory test needs no proof of knowledge, recklessness or carelessness, and no duty of care. An entirely honest statement can still breach s 18 of the ACL if it misleads. The common law categories remain important for the remedy: fraudulent misrepresentation sounds in the tort of deceit, and damages for deceit aim to put the victim in the position they would have been in without the false statement, which can be significantly more generous than a contractual measure.

Why the Australian Consumer Law usually runs the show

The Australian Consumer Law (the ACL) is Schedule 2 of the Competition and Consumer Act 2010 (Cth). Section 18(1) provides that a person must not, in trade or commerce, engage in conduct that is misleading or deceptive or is likely to mislead or deceive. A few features of that section matter for business contracts.

First, there is no consumer threshold. A common misconception is that the ACL protects consumers only. For s 18, that is wrong. It protects any person, including a business, as long as the conduct happened in trade or commerce, which most business-to-business dealings are. The consumer tests in s 3 of the ACL (a price of $100,000 or less, or goods or services of a kind ordinarily acquired for personal, domestic or household use, with carve-outs for re-supply and transformation) apply to consumer-specific protections such as the consumer guarantees. They do not gate s 18. A founder who pays several hundred thousand dollars to acquire a business can sue under s 18.

Second, the focus is the overall conduct, not a single sentence. Courts look at the whole course of dealing: what was said, what was left out, and how a reasonable businessperson would have understood it. That is why fine print and disclaimers do not automatically protect a seller whose overall messaging misleads.

Third, silence can mislead. The leading illustration is Henjo Investments Pty Ltd v Collins Marrickville Pty Ltd (1988) 39 FCR 546. The vendors sold a restaurant in Double Bay known as the New York Deli. They presented the business's takings to the purchaser without disclosing that council approval and the liquor licence capped seating at 84 people. The Full Federal Court held the silence could be misleading conduct under s 52 of the Trade Practices Act 1974 (Cth), the predecessor of s 18 of the ACL. It also held that the purchaser's failure to make its own enquiries did not defeat the claim, and that the exclusion clauses in the contract did not operate as a defence to the statutory claim.

Fourth, the statutory liability sits outside the contract, so an entire agreement clause cannot simply contract it away. Such a clause can still matter, because it bears on whether the recipient actually relied on outside statements, but it is not a magic shield.

Fifth, claims have a time limit. An action for damages under s 236 of the ACL can be commenced within six years after the cause of action accrues, so delay can cost a claim.

Reliance: the question most disputes turn on

For a statement to give rise to rights, it must have been relied on. The statement has to have played a real part in the decision to sign. This is where most disputes are won and lost, and courts tend to ask a series of practical questions:

Was the statement a clear statement of fact, or an opinion, estimate or sales talk?
Was it specific enough to be relied on?
Did the other party actually rely on it, or did they make their own checks?
Was it corrected before the contract was signed?
What did the whole course of conduct convey?

The High Court's decision in Campbell v Backoffice Investments Pty Ltd (2009) 238 CLR 304 shows how central reliance is. The purchaser paid $850,000 for one of the two shares in Healthy Water (NSW) Pty Ltd after the vendor supplied financial documents, including add-backs that overstated non-recurring expenses, and estimates of sales revenue and earnings that he knew, or ought reasonably to have known, were not being achieved. The litigation turned on causation and reliance: whether the loss was suffered by conduct of the vendor, with a clause in the share sale agreement warranting that the purchaser had not relied on any representations outside the agreement treated as relevant to that question.

Estimates and forecasts are part of normal business negotiation, and a projection is not a misrepresentation merely because it does not come true. But an opinion or forecast carries an implied claim that the person making it has a reasonable basis for it. A confident assertion that "this business will definitely double next quarter" implies grounds for that confidence, and a forecast can mislead when the person making it knows the numbers are already off track, as the vendor's estimates in Campbell illustrate. The practical habit is to label what is verified fact, what is an estimate, and what assumptions the estimate depends on.

Silence deserves a special mention. At common law, silence is generally not a misrepresentation. Under the ACL, the position is different where what is left unsaid makes what was said misleading. A seller who tells half the story, or who provides a data room of documents while making verbal assurances that the records do not support, is exposed in exactly the way the vendor in Henjo was.

What remedies are available

If a misrepresentation is established, the remedies depend on the legal basis of the claim. The main options are:

Rescission: The affected party seeks to unwind the contract and restore both sides, as far as possible, to their pre-deal positions. This is the classic misrepresentation remedy, and it is most useful where the false statement went to the heart of the deal, such as the value of a business or the condition of its assets. Rescission is not always available. It can be lost by affirming the contract after discovering the truth, by delay, or where restoring the parties is no longer practical because the position has changed.
Damages: A victim of fraudulent misrepresentation can sue in the tort of deceit for damages that aim to put them in the position they would have been in without the false statement. Under s 236 of the ACL, a claimant who suffers loss or damage because of a contravention of s 18 can recover the amount of that loss or damage, within the six-year limit.
Court orders under the ACL: Sections 237 and 243 of the ACL give a court a flexible toolkit on top of damages. It can declare the whole or part of a contract void, including void from the start, vary the contract, refuse to enforce particular provisions, direct a refund of money or return of property, and order payment of the amount of the loss.
Termination and settlement: Many misrepresentation disputes never reach judgment. They end in refunds, renegotiated terms, termination of the deal, or settlement, with the strength of a potential s 18 claim driving the negotiation.

Liability caps and exclusion clauses deserve a warning. A clause limiting liability can allocate risk between the parties, but it cannot simply exclude a claim for misleading or deceptive conduct, because that liability arises from the statute, not from the contract. Contract drafters should treat limitation clauses as risk allocation, not as a way to switch off the ACL.

Cutting the risk before you sign

Misrepresentation risk is best handled before the deal is signed, and most of it comes down to a few practical disciplines:

Put the statements that matter into the contract: If you are relying on something, write it in as a warranty (a promise that a fact is true), a condition precedent (something that must happen before completion), or a defined deliverable or specification. That converts a reliance question into a contract question, which is much easier to enforce.
Use an entire agreement clause, but treat it as one layer of protection: It narrows arguments that "we agreed this in the meeting", but it does not extinguish exposure under s 18, and courts still look at what actually happened.
Do due diligence that matches the size of the deal: Buying a business: review the financials, customer contracts, employee arrangements, IP ownership and compliance. Signing a supplier deal: check certifications, lead times and capacity to deliver at scale. Procuring software: confirm the features exist today, not on a roadmap.
Keep sales, marketing and contract documents consistent: A sales deck promising 24/7 support next to a contract that limits support to business hours is a self-inflicted misrepresentation claim waiting to happen. A single source of truth for what the business promises keeps marketing and legal on the same page.
Document the basis of estimates: Label what is verified fact, what is a projection, and what assumptions the projection depends on. A forecast that is clearly an estimate is far less likely to be read later as a guarantee.

How a commercial lawyer helps with misrepresentation risk

Some of the judgements involved here are ones a general article cannot make for you. A commercial lawyer can help with:

Assessing whether a statement crosses the line: Whether particular words are a representation, an opinion or protected sales talk depends on their specificity and context. A lawyer can review the negotiation history and tell you whether a claim is realistically arguable.
Choosing the right legal basis: Most claims run under s 18 of the ACL because it needs no proof of fault, but fraudulent misrepresentation can support higher damages and different remedies. Fraud has to be pleaded distinctly and clearly proved, so a lawyer can assess whether the evidence can support it.
Drafting the contract-side protections: Warranties, conditions precedent, entire agreement clauses and disclosure schedules are drafting choices. Done well they allocate risk; done badly they create ambiguity.
Managing a live dispute: Preserving evidence, responding to a claim, negotiating a refund, rescission or compensation, or preparing for court, all within limitation periods such as the six-year window in s 236 of the ACL.

If you are on the receiving end of a misrepresentation claim, or you are about to sign a contract where key promises were made outside the written terms, an early conversation with a lawyer is cheaper than the dispute.

The statement you did not write down is the one that bites

The pattern that produces the most claims is not the deliberate lie. It is the confident pre-contract statement that never made it into the written contract, combined with a belief that the Australian Consumer Law only protects consumers. It does not: s 18 of the ACL protects businesses in business-to-business deals, catches half-truths and silence, and survives disclaimers and entire agreement clauses. If you are a buyer, that is a remedy you may not know you have. If you are a seller, it is exposure you cannot contract your way out of. Before signing, the question to ask is not only whether the statement is true, but whether the other side is relying on it.

To summarise: a misrepresentation is a false pre-contract statement or conduct that induced the contract. The three common law categories (innocent, negligent and fraudulent) affect remedies, but in practice most claims run under s 18 of the ACL, which needs no proof of fault and applies to businesses as much as consumers. Reliance is the hinge of most disputes, and courts look at the whole course of conduct, including what was left unsaid. Remedies range from rescission and damages to court orders that void, vary or refuse to enforce the contract. The cheapest protection is preventative: put key statements in the contract as warranties, keep marketing consistent with the terms, and do due diligence that matches the size of the deal.
