Background
In 2019, David Abela and Rebecca Amos engaged Atlanta Building Pty Ltd to construct a residential dwelling on their property in Bangalow, NSW under a fixed-price contract worth $2,699,258.10. The contract was a standard form Australian Building Industry Simple Works Contract. However, the parties mishandled the deposit provision by erroneously including it as the first stage in the Stage Payments Schedule, creating confusion about its treatment.
Following the owners’ separation and divorce, they terminated the contract in August 2021. Mr Abela subsequently entered bankruptcy, leaving only Ms Amos as the defendant. At trial, Atlanta claimed damages for lost profits of $171,106.66 based on an asserted 15% profit margin on the uncompleted works. The primary judge rejected this claim.
At the conclusion of trial, Atlanta sought leave to amend its pleading to claim $134,962.91 (later refined to $123,325.18) for the unpaid deposit or unpaid contract works—an amount not previously pleaded. The primary judge refused this application without hearing from the parties.
The Court’s Holding
The Court of Appeal dismissed Atlanta’s appeal on all grounds. Regarding the amendment, Ball JA (with whom Leeming JA and Free JA agreed) found that while Atlanta was entitled to procedural fairness and was denied the opportunity to be heard, any procedural error was not material. The extreme lateness of the amendment, its internal inconsistency, and the absence of clear prospects of success provided a sufficient basis for refusal.
On the lost profits claim, the court upheld the primary judge’s rejection. Atlanta failed to adduce admissible evidence of its actual likely costs of completing the work. The expert witness’s opinion rested on industry averages (10–20% contractor margins) rather than Atlanta’s specific anticipated costs. Critically, the fact that the parties agreed to a 15% margin for cost-plus variations under the contract did not support a conclusion that Atlanta would achieve 15% profit on the fixed-price component. The court noted that Atlanta could have provided its expert’s evidence of actual likely costs but failed to do so.
The Court of Appeal also upheld the primary judge’s discretionary decision to award no costs, considering the judgment amount, the disproportionate costs incurred, and the multiple issues on which Atlanta failed.
Key Takeaways
- Procedural fairness requires notice and opportunity to be heard, but errors in procedure are not material if the outcome would have been identical regardless.
- In construction disputes, a party claiming lost profits must prove actual anticipated costs, not industry averages or contractual margins applied to other payment mechanisms.
- Late amendments to pleadings made at or after trial, especially when internally inconsistent and lacking clear prospects of success, will be refused even if procedural steps were imperfect.
- Courts have broad discretion to decline costs awards based on factors including the judgment amount, disproportionate litigation costs, and the party’s failure on multiple claims.
Why It Matters
This decision clarifies the evidentiary burden for contractors claiming lost profits on fixed-price contracts. Relying on industry standards or contractual margins for variations is insufficient; courts require concrete evidence of the contractor’s own estimated costs of completion. For construction practitioners, the decision underscores the importance of documenting anticipated costs during contract performance, not merely after termination.
The procedural fairness holding also confirms that Australia’s courts will not overturn substantive outcomes on procedural grounds alone. While Atlanta was denied the opportunity to be heard on its amendment request, the Court found the result defensible based on the amendment’s merits. This principle protects finality and discourages litigants from exploiting technical procedural defects when their underlying claims lack merit.
