Key Takeaways
- In Tycho Pty Ltd v Trustworthy Nominees Pty Ltd [2026] QSC 89, the Queensland Supreme Court refused leave to amend a pleading to add a new cause of action after the relevant limitation period had expired.
- UCPR r 376(4) requires the court to consider it appropriate — and the new cause of action must arise from the same or substantially the same facts as those already pleaded.
- Even where the other party cannot demonstrate specific prejudice, a court may refuse the amendment if it comes with no proper explanation, is made very late, and risks the trial dates.
- Queensland courts expect litigants and their lawyers to identify all available causes of action at the outset — not as the case develops over years of litigation.
- Strategic pleading decisions made early in litigation carry permanent consequences: causes not pleaded by limitation expiry may be lost forever.
What This Decision Is About
The Queensland Supreme Court’s decision in Tycho Pty Ltd v Trustworthy Nominees Pty Ltd [2026] QSC 89 is a cautionary tale for any Queensland litigant who assumes they can refine or supplement their legal case as litigation unfolds. The decision, delivered by Freeburn J, arose out of long-running professional negligence proceedings. A party sought leave under r 376(4) of the Uniform Civil Procedure Rules 1999 (Qld) (UCPR) to amend its third party claim to introduce a new cause of action under s 61 of the Australian Consumer Law — after the limitation period for that claim had already expired. The court refused.
The Background: Eight Years In, A New Idea Emerges
In February 2018, Trustworthy Nominees Pty Ltd was sued. Shortly after, it commenced third party proceedings against its former solicitors for professional negligence. In March 2026 — approximately eight years after those proceedings began — Trustworthy applied to amend its third party claim to add a new cause of action under s 61 of the ACL (guarantees as to fitness for purpose of a service).
The motivation was commercially significant: a s 61 ACL claim is not apportionable, whereas the existing claims in negligence and under s 60 ACL were apportionable. A successful amendment would have significantly increased the potential recovery against the defendant solicitors. The problem: it was eight years too late, with no good explanation for the delay, and all evidence had already been filed.
The Legal Framework: UCPR Rule 376(4)
Rule 376(4) of the UCPR governs amendment applications where the limitation period for the new cause of action has already expired. It provides that the court may grant leave only if:
- the court considers it appropriate; and
- the new cause of action arises out of the same facts or substantially the same facts as a cause of action for which relief has already been claimed.
Both conditions must be met. Critically, the first condition — “appropriate” — gives courts broad discretion to refuse even where the second condition might otherwise be satisfied.
Why the Court Refused: The Key Factors
1. The Lateness Was Extreme and Unexplained
Trustworthy had been represented by solicitors and counsel throughout eight years of litigation. The question of apportionment had been alive since 2018. The new idea emerged from “close scrutiny” of the existing pleadings apparently conducted for the first time just before the amendment application. That is not a satisfactory explanation for an eight-year delay.
2. All Evidence Had Already Been Filed
This was not an early-stage application. All evidence-in-chief had been filed, a trial plan had been submitted, and trial dates had been set. Granting the amendment would require evidence and disclosure to be revisited.
3. The Passage of Time Threatened the Quality of Justice
The proposed new claim required inquiry into events from 2017 — nine years earlier. Even where witnesses are still available, the quality of recollection diminishes significantly over time. Queensland courts are alive to this risk.
4. Trial Dates Were at Risk
Permitting the amendment would have placed fixed trial dates at risk. The court’s administration of justice for all litigants — not just this case — becomes a relevant factor once a matter reaches the trial list.
5. The Amendments Were Substantial
This was not a minor correction. The proposed amendments called into inquiry a substantial new body of facts and legal analysis. Courts treat substantial amendments differently from minor technical corrections, particularly at an advanced stage.
6. There Was No Proper Justification
The absence of demonstrable prejudice to the defendant was not sufficient to justify a substantial late amendment. The court’s broader interest in proper administration of justice — finality, efficiency, proportionality — independently weighs against such applications.
What This Means for Queensland Litigants
The practical implications are significant for any Queensland business involved in, or contemplating, commercial litigation:
Case Theory Must Be Complete Before Filing
Every cause of action you intend to rely on should be identified, pleaded, and particularised before commencing proceedings. The idea that you can “lock in” your position and refine it as litigation evolves is a dangerous misconception in Queensland’s UCPR environment.
Apportionment Implications Require Early Analysis
Claims in negligence and certain ACL provisions are apportionable under Queensland law. Non-apportionable claims (such as s 61 ACL fitness-for-purpose) allow full recovery from a single defendant. This is a strategic decision that must be made at the outset, with comprehensive legal advice.
Professional Negligence Claims Need Particular Care
Professional negligence matters frequently engage multiple causes of action: negligence, breach of contract, s 60 ACL, s 61 ACL, and sometimes s 18 misleading conduct. Failing to plead all available heads in the initial statement of claim can be irreversible.
The “Arises From the Same Facts” Test Has Limits
In Tycho, the court rejected the application on the “appropriate” ground alone, without even needing to analyse whether the new cause arose from the same facts. Rule 376(4) is not a guarantee of access to amendment.
Practical Checklist: Before You File in Queensland
- Conduct a comprehensive cause-of-action audit before filing. Identify every possible legal basis across contract, tort, ACL, statute, and equity.
- Map limitation periods for each cause of action. The Limitation of Actions Act 1974 (Qld) sets different periods for different claims. Know every deadline before you begin.
- Assess apportionment implications strategically. Decide now which claims to plead — not in year eight.
- Plead specifically and comprehensively from day one. Vague pleadings create problems at trial and restrict your ability to run arguments not on the record.
- Review pleadings at each stage milestone. Directions hearings and interlocutory stages are natural review points. Do not wait for the eve of trial.
- If you need to amend, move early. Courts are far more tolerant of amendments before evidence is filed. The same application at year one of Tycho, properly explained, would likely have been granted.

Frequently Asked Questions
Can I add a new cause of action to my claim after the limitation period has expired in Queensland?
You can apply for leave to amend under r 376(4) of the UCPR, but the court has a broad discretion to refuse. It must consider it “appropriate” and the new cause of action must arise from substantially the same facts. Courts scrutinise lateness, explanation for delay, and impact on trial readiness — and may refuse even where there is no specific prejudice to the other side.
What is the limitation period for commercial disputes in Queensland?
Under the Limitation of Actions Act 1974 (Qld), most contract and property claims carry a 6-year limitation period. Personal injury claims are generally 3 years. The period runs from when the cause of action accrues.
What is an apportionable claim in Queensland and why does it matter?
Apportionable claims allow the court to divide liability among concurrent wrongdoers proportionately. Non-apportionable claims — like s 61 ACL — allow full recovery from a single defendant. The strategic choice between apportionable and non-apportionable causes of action must be made at the outset of litigation.
How do I ensure my pleadings capture all available causes of action?
Engage a commercial litigation lawyer to conduct a comprehensive audit before filing. Identify every legal basis across contract, tort, ACL, equity, and applicable legislation, and map the relevant limitation periods for each claim.
What happens if I need to amend my pleadings during litigation?
If the limitation period has not expired, amendment under r 376(1)–(3) UCPR is more accessible. If it has expired, the stricter r 376(4) requirements apply and courts retain full discretion to refuse. Moving early, with a proper explanation, is always the better position.
