Most business disputes do not begin with a loud failure. They begin with a signal. A supplier emails that it will not deliver. A customer withholds a milestone payment and tells you not to bother finishing the work. A contractor walks off site. The signal arrives before the due date, while you still have time to react, and contract law gives it a name: repudiation.
This article explains what counts as repudiation in Australian contract law, why it is not the same thing as a breach, the choice the law forces on you when it happens, and what termination and damages actually involve. It also covers the traps that cost businesses money, and where a lawyer earns their keep.
What counts as repudiation
A party repudiates a contract when their words or conduct show they do not intend to perform it. The classic statement comes from the High Court in Koompahtoo Local Aboriginal Land Council v Sanpine Pty Ltd [2007] HCA 61, which described repudiation as conduct evincing an unwillingness or an inability to render substantial performance of the contract. More precisely, it is conduct that evinces an intention no longer to be bound by the contract, or to fulfil it only in a manner substantially inconsistent with the party's obligations.
The test is an objective one. The question is not what the party secretly intended, but whether their conduct would convey to a reasonable person in your position that they have renounced the contract as a whole, or a fundamental obligation under it. As the High Court noted in Koompahtoo, actions may speak louder than words.
Express or implied repudiation
Repudiation can be express or implied.
- Express repudiation: A clear statement that the party will not perform, such as "we're cancelling the order and won't be supplying you", "we're not paying the final milestone", or "we're walking off the job".
- Implied repudiation: Conduct from which the intention is inferred, such as shutting down the project, selling the equipment needed to fulfil the order, removing the entire team, or abandoning premises while the lease continues to run.
The High Court confirmed in Laurinda Pty Ltd v Capalaba Park Shopping Centre Pty Ltd [1989] HCA 23 that repudiation can be inferred from conduct alone. In that case, a lessor's persistent failure over a long period to do something the lease required it to do was enough to support an inference of repudiation, even though the lessor never said it would not perform.
Repudiation is not confined to supply or service contracts. The High Court has applied the same principles to commercial leases in Progressive Mailing House Pty Ltd v Tabali Pty Ltd [1985] HCA 14, so tenants and landlords can repudiate leases just as suppliers and customers can repudiate supply agreements.
Why repudiation is not yet a breach
A breach of contract is an actual failure to perform an obligation when it falls due: goods not delivered on the delivery date, an invoice left unpaid, work that does not meet the specification. Repudiation is different. It can happen before anything is due, which is why it is often described as an anticipatory failure.
The High Court dealt with exactly this in Foran v Wight [1989] HCA 51. Two days before the settlement date, the vendors' solicitor said they could not complete on the day fixed because the right of way the contract required them to register had not been registered. Completion on that date was an essential term. The statement was held to be a repudiation even though the settlement date had not yet arrived: it was a refusal to perform an essential term before the time for performance.
That is the practical point of the distinction. Repudiation gives you legal options before you have suffered the full consequences of non-performance. But it is not itself a completed breach, because the obligation may not yet be due. Nor does it automatically end the contract. What it does is trigger a choice.
There is a reverse side to this. A pattern of actual breaches can themselves amount to repudiation. In Koompahtoo, the High Court noted that a failure to perform, even if not a breach of an essential term, may manifest an unwillingness to perform in circumstances where the other party is entitled to conclude that the contract will not be performed substantially according to its requirements. So the two concepts overlap: a series of failures can be the evidence from which repudiation is inferred.
The choice: accept or affirm
This is the heart of how the mechanism works. When one party repudiates, the law does not end the contract. It gives the innocent party an election: accept the repudiation and treat the contract as at an end, or affirm the contract and keep it on foot.
The High Court explained in Foran v Wight that a repudiation does not affect the continued existence of the contract unless the innocent party elects to rescind. If the innocent party does not elect to treat the contract as ended, both parties remain bound, and the party who repudiated can take advantage of any supervening circumstance that justifies them in refusing to perform when the time for performance arrives. In plain terms: if you do not accept a repudiation promptly and clearly, the other side can change their mind, perform after all, and the repudiation is effectively spent.
The election can be made by words or by conduct, and it is not always reversible. If you immediately engage a replacement supplier, cancel your side of the arrangement, or refuse any further performance, your conduct may be treated as an acceptance. If you keep performing and demanding performance, you may be treated as having affirmed. This is why a measured, documented response matters more than a fast one.
There is one condition attached to accepting. You must have been ready, willing and able to perform your own side of the bargain down to the moment you accept the repudiation. The High Court confirmed in Foran v Wight that the requirement of readiness and willingness runs up to the point of election. If you could not have performed in any event, accepting the repudiation may not get you very far.
What accepting gets you: termination and damages
Accepting a repudiation does two things. It ends the contract from that point on, discharging both parties from future performance. And it opens the door to damages for the loss the repudiation causes.
Termination
Two grounds can justify ending a contract at common law.
- Repudiation itself: Renunciation of the contract as a whole, or of a fundamental obligation under it.
- A sufficiently serious breach: A breach of an essential term, or a breach of an intermediate term that is serious enough to go to the root of the contract.
The High Court set out this classification in Koompahtoo, distinguishing between conditions, warranties and intermediate terms, and confirming that termination is only available for a breach of an essential term or for a sufficiently serious breach of an intermediate term.
Your contract will often add a layer on top of the common law. Termination clauses may require a specific form of notice, allow a cure period, or give a right to suspend work for non-payment. Follow them precisely. A termination that does not comply with the contract's own process can be invalid, and an invalid termination can itself amount to a repudiation by you. In Commonwealth v Amann Aviation Pty Ltd [1991] HCA 54, the Commonwealth's invalid notice of termination was itself treated as a repudiation, entitling the contractor to terminate and sue for damages.
Damages
On damages, the governing principle in Australia was restated by the High Court in Amann Aviation: damages for breach of contract are intended to put the innocent party, so far as money can, in the position they would have been in had the contract been performed. In practice that can be measured as:
- Lost profit: The profit the contract would have produced if it had been performed.
- Wasted expenditure: Money spent preparing for or performing the contract that is now wasted, often relied on where profit cannot be established.
- Cover costs: The extra cost of arranging a replacement supplier, contractor or product.
The innocent party also has to take reasonable steps to mitigate the loss, and can generally only recover losses that were reasonably foreseeable at the time the contract was made. Documentation is central to all of this: quotes, invoices, project plans, correspondence and records of mitigation efforts all become evidence.
What survives termination
Even after a contract ends, some obligations commonly survive. Confidentiality clauses, intellectual property ownership and licensing terms, restraints that are enforceable, and dispute resolution clauses are all designed to operate after the contract has finished. Termination ends future performance; it does not wipe out rights that have already accrued or clauses that were meant to outlast the contract.
Where it goes wrong
The main ways businesses lose on repudiation are consistent.
- Terminating without grounds: The terminating party ends up accused of repudiation itself, and defending a damages claim instead of running one.
- Failing to make a clear election: The choice is made by conduct without anyone noticing, and the party discovers later that it accepted when it wanted to affirm, or affirmed when it wanted out.
- Affirming and watching losses grow: Keeping performance going while the other side still does not perform, and finding the losses are not fully recoverable.
- Sitting on a repudiation: Waiting too long before accepting, by which point the other side has performed or the position has changed.
- Misreading the signal: Treating a frustrated remark as a repudiation when the other side later performs, or missing an implied repudiation because nothing was said out loud.
Evidence is a recurring problem too. Repudiation is proved by words and conduct, so if the emails, messages and records of what was said are not kept, the argument is hard to run later.
When a lawyer should be involved
Repudiation is one of the few areas of contract law where the value of advice is concentrated in a short window: between the signal and the election. A lawyer can assess whether the words or conduct meet the repudiation test, whether the term in issue is essential, whether your contract's termination clause has been complied with, and how the election should be made in writing so it cannot later be characterised as something else. If you are on the receiving end of a termination notice, the same assessment runs in reverse: was the other side entitled to terminate, or have they repudiated the contract themselves?
The cost of that advice is small compared with the cost of a wrong election, which can leave you locked into a contract you wanted out of, or exposed to a damages claim for terminating without grounds.
Your election: terminate or affirm
If there is one thing to take from this article, it is timing. Repudiation does not end a contract by itself. The outcome turns on what you do next, and the law treats your words and conduct as the election.
If you want out, say so in writing, stop performing on a clear date, and keep the evidence that you were ready, willing and able to perform. If you want the deal to continue, say that too, and do not do things that contradict it. If there is any doubt about whether the other side's conduct is repudiation at all, get advice before you act rather than after. An early conversation with a commercial lawyer, often at no cost, can tell you whether you are looking at a repudiation, a breach, or a dispute that can still be rescued.
