A damaging statement has been published about your business — a competitor's post, a hostile review, an email to your clients. You want it removed, corrected, or to recover the financial hit. Your lawyer mentions two possible paths: defamation and injurious falsehood. They sound alike, but they protect different things, require different proof, and suit different plaintiffs. Choosing the wrong one can cost you time, money, and — for larger companies — the right to bring a claim at all.
The real question underneath the obvious one
The surface question is "defamation or injurious falsehood?" The practical question is narrower: what was the false statement about, who made it, and what harm did it actually cause?
Defamation protects a person's reputation. Injurious falsehood protects a business's financial interests. If a statement attacks your personal standing as a founder or director, defamation may fit. If it disparages your products, services, or business to drive away customers or clients, injurious falsehood is more likely the right frame. And if the statement was made by a trade competitor in a commercial context, the Australian Consumer Law (ACL) may offer a cleaner path than either.
One option that often looks available but isn't: most for-profit companies with ten or more employees cannot sue for defamation at all. Under s 9 of the Defamation Act 2005, only an "excluded corporation" — broadly, a non-profit, or a corporation with fewer than ten employees that is not an associated entity of another corporation — can bring a defamation claim. If your company does not meet that definition, defamation is off the table regardless of how damaging the statement was.
The target of the statement and proof of malice
What the statement was actually about
The threshold question is whether the statement attacks a person or a business.
- Person targeted: A claim that your CEO is dishonest, incompetent, or corrupt is primarily reputational harm to an individual. Defamation is designed for this. An excluded corporation attacked in its own right may also bring a defamation claim if the publication is directed at the corporation itself.
- Business or products targeted: A false claim that your software has a security flaw, your food products are contaminated, or your services are unlicensed is directed at the business and its commercial offering. That is the domain of injurious falsehood.
The distinction matters because courts look at the natural meaning of the publication. A statement that blurs both — attacking a director in terms that also damage the company — may give rise to parallel claims by the individual and, depending on size, the company.
What you can prove about the publisher's state of mind
Injurious falsehood requires proof of malice. That means showing the publisher knew the statement was false, was recklessly indifferent to its truth, or acted with an improper purpose — such as damaging a competitor's business. As Palmer Bruyn & Parker Pty Ltd v Parsons (2001) 208 CLR 388; [2001] HCA 69 confirms, knowledge of falsity or recklessness as to truth is sufficient to establish malice.
Defamation does not require proof of malice to establish the cause of action (though malice can defeat certain defences, such as qualified privilege).
- Evidence of malice is strong — internal emails, prior warnings you sent, a pattern of targeted posts, a clear competitive motive: injurious falsehood becomes viable.
- No clear evidence of malice — defamation (where available) or the ACL may be easier to run, because neither requires you to prove the publisher's state of mind.
What financial loss you can document
Injurious falsehood requires proof of special damage: actual, measurable financial loss flowing from the publication. Lost contracts, cancelled orders, a supplier who terminated your arrangement after seeing the statement — all with documentary evidence linking cause to effect.
Defamation does not require proof of specific economic loss to recover general damages for harm to reputation.
- You have invoices, cancellation emails, and a clear causal chain: injurious falsehood is viable and may yield focused compensation for the economic loss.
- Harm is reputational and diffuse, hard to quantify in dollars: defamation general damages are available without that proof burden, provided you meet the serious harm threshold.
Whether the serious harm threshold applies
Under s 10A of the Defamation Act 2005, a defamation claim requires the plaintiff to show that the publication has caused, or is likely to cause, serious harm to reputation. For an excluded corporation, harm to reputation is not "serious harm" unless it has caused, or is likely to cause, serious financial loss to the corporation.
This threshold was introduced in the 2021 uniform law reforms and it filters out minor grievances. If the statement was limited in reach — seen by a handful of people, quickly taken down — demonstrating serious harm will be harder.
Injurious falsehood has no equivalent threshold. You must prove malice and actual loss, but there is no separate "seriousness" gate.
The limitation period
The clock matters, particularly for defamation.
| Claim | Typical limitation period |
|---|---|
| Defamation | 1 year from publication |
| Injurious falsehood | Standard limitation period (generally longer) |
| ACL claim for loss | Limitation period under applicable legislation |
The defamation limitation is strict. Under the uniform scheme (implemented in NSW through the Limitation Act 1969), proceedings must commence within one year of publication, though a concerns notice given near the end of that period can trigger a limited extension. If you have missed or are close to the deadline, defamation may already be unavailable.
Injurious falsehood, as a common law tort, is subject to the general limitation period applicable in your state — typically longer — giving you more runway to gather evidence of financial loss before filing.
The concerns notice requirement
Before commencing defamation proceedings, s 12A of the Defamation Act 2005 requires the plaintiff to give the publisher a concerns notice — a formal letter setting out the defamatory imputations complained of and, for excluded corporations, particularising the serious financial loss alleged. The publisher then has an opportunity to make an offer of amends.
Injurious falsehood has no equivalent pre-action requirement (though a well-drafted letter of demand remains tactically sound before any litigation).
When each claim is stronger
Profile of a stronger defamation claim:
- Statement targets an individual's personal reputation (or an excluded corporation directly)
- Company has fewer than 10 employees (or is a non-profit)
- Publication was wide-reaching and the reputational impact can be shown
- Malice is absent or hard to prove
- You can move quickly — still within the 1-year window
- A concerns notice response may resolve the matter without litigation
Profile of a stronger injurious falsehood claim:
- Statement disparages your products, services, or business (not just a person)
- Company has 10 or more employees (making defamation unavailable)
- You have documentary evidence of lost contracts, cancellations, or revenue drop
- There is clear evidence the publisher knew the statement was false or had a competitive motive
- You need more time to build the financial loss case
When the ACL is worth considering first:
s 18 of the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)) prohibits misleading or deceptive conduct in trade or commerce. s 29 prohibits false or misleading representations about goods or services. If a competitor or trading partner made the false statement in a commercial context, an ACL claim may be available without needing to prove malice, with compensation for loss available under s 236 of the ACL.
The ACL path is often attractive because the malice hurdle disappears, the limitation regime differs from defamation, and it can run alongside an injurious falsehood claim where the facts support both.
Where Artificer Legal can help
These claims look straightforward on paper but turn on how your specific facts map to each element. A few of the places where legal advice makes a material difference:
- Assessing eligibility: Is your company an excluded corporation? Does the publication cause "serious harm" on the facts? These are threshold questions that determine which claims are even open to you.
- Malice evidence: Whether you have enough to establish malice for injurious falsehood — or whether the evidence you have is better deployed under the ACL — requires an assessment of what you can actually prove at the time you need to decide, not later.
- Limitation deadlines: The 1-year defamation window runs from publication, not from when you became aware of the statement. Missing it forecloses the option entirely.
- Concerns notice drafting: A poorly drafted concerns notice can undermine a defamation claim before it starts. For excluded corporations, the notice must particularise the serious financial loss.
- Claim combination strategy: Running injurious falsehood and an ACL claim in parallel, or defamation and injurious falsehood together (where available), requires coordinated pleading and consistent factual allegations.
Artificer Legal's commercial litigation practitioners can assess which claims are available on your facts, advise on the strength of each, draft pre-litigation correspondence, and help you choose a strategy that matches your actual goal — whether that is a quick takedown, a retraction, or full compensation.
The clearest signal
The single factor that most often decides the question is who can sue. If your business is a for-profit company with ten or more employees, defamation is not available to you — full stop. From there, the choice between injurious falsehood and the ACL turns on whether you can prove malice. If you can, injurious falsehood targets the economic loss directly. If you cannot, or if the publisher acted in trade or commerce, the ACL's misleading conduct provisions offer a path that does not require it.
For businesses that are eligible for defamation — smaller companies and individuals — the 1-year limitation period is the most frequently overlooked constraint. The moment a damaging publication appears, the clock starts. Gathering evidence, assessing seriousness, and sending a concerns notice all need to happen within that window.
The practical heuristic: identify what was targeted (reputation or revenue), determine who is eligible to sue, check the clock, and then assess what you can prove about the publisher's state of mind. Those four questions will usually point clearly to one path — or reveal that you need more than one running at once.
