Hassall Developments Pty Ltd (Receivers and Managers Appointed) (in liq) v QBE Insurance (Australia) Limited

This case arose out of a commercial insurance dispute between Hassall Developments and QBE. The immediate issue before the Court was not the final insurance claim itself, but a procedural application about who should be in the case and what documents had to be produced.

The background dispute was commercially significant. A threshold question was when insurance cover was bound. Hassall Developments said cover was bound on 19 July 2022 or, alternatively, 20 July 2022. QBE said cover was not bound until 12 August 2022. QBE also pleaded that a 19 July 2022 confirmation of cover “effective 19/07/2022” was only confirmation of “holding or interim cover”.

That issue mattered because the Court had already ordered a separate question hearing to deal with important threshold matters, including whether QBE could reduce any liability to nil under section 28(3) of the Insurance Contracts Act 1984 (Cth), whether QBE engaged in misleading or deceptive conduct in connection with its 19 July 2022 confirmation of cover, and what would have happened if that alleged conduct had not occurred.

The procedural turning point came when QBE's pleaded position was shown to have changed over time. The Court recorded three stages. First, in pre-litigation correspondence dated 27 September 2023, QBE's solicitors said cover was provided from 19 July 2022 under the auto-cover scheme. Second, in QBE's initial defence filed on 11 December 2024, QBE denied that any cover was bound on 19 July 2022 and alleged that the contract of insurance was not entered into until 12 August 2022.

Third, in its amended defence, QBE alleged for the first time an oral agreement between Ms Pigram of QBE and Mr Collins of Gallagher for “hold cover” from 4 pm on 19 July 2022 pending offer and acceptance, and said that agreement was made outside the QBE underwriting guide.

After QBE served evidence in March 2026 supporting that amended position, Hassall Developments applied to join its former broker, Arthur J. Gallagher & Co (AUS) Limited, as an additional respondent. It also sought further discovery from QBE in four categories of documents.

The Court was dealing with two procedural requests. First, should Hassall Developments be allowed to amend its case to join Gallagher as a second respondent? Second, should QBE be ordered to give discovery of the four categories of documents sought in the interlocutory application?

The joinder issue was important because the case was already on foot and a separate question hearing had been listed to start on 1 June 2026. QBE argued that joining Gallagher at that stage would cause prejudice, especially if the hearing dates had to be vacated and relisted. QBE also argued that Gallagher was not necessary to decide the dispute between Hassall Developments and QBE.

Hassall Developments argued that QBE's latest version of events changed the landscape. If QBE was now saying there had been an oral agreement between insurer and broker for hold cover on 19 July 2022, that raised overlapping issues about what the broker did, what was communicated to the insured, and whether the broker should be heard and bound by any findings on those events.

The Court therefore had to balance case management efficiency, fairness to the existing parties, the risk of inconsistent findings, and the practical disruption that joinder might cause to the hearing timetable.

The Court referred to rules 9.02(1) and 9.05(1) of the Federal Court Rules 2011 (Cth). Those rules allow parties to be joined where separate proceedings would give rise to a common question of fact or mixed fact and law, where the rights to relief arise out of the same transaction or series of transactions, or where joinder is appropriate by leave of the Court. Rule 9.05(1) also recognises joinder where it is necessary to enable determination of a related dispute and avoid multiplicity of proceedings.

The Court also referred to the overarching purpose in section 37M of the Federal Court of Australia Act 1976 (Cth), which is to facilitate the just resolution of disputes according to law as quickly, inexpensively and efficiently as possible. In practical terms, that meant the Court was not asking only whether Gallagher was strictly indispensable. It was also asking whether joinder was desirable to resolve overlapping issues properly and efficiently.

Justice Jackman accepted Hassall Developments' submission that QBE's latest iteration of its response, if established, would cast in a new light issues concerning Gallagher's performance of its services as broker. The Court noted Hassall Developments' contentions that the alleged oral agreement for interim cover was not disclosed to it and that no advice was provided about the impact on the duration of the duty of disclosure.

The Court made no findings on those matters, but treated them as contentions that helped explain why broker-related issues had become material.

The Court also considered whether Gallagher should have the opportunity to adduce evidence about what occurred on 19 July 2022 and whether it should be bound by the determination of those issues. Although Hassall Developments could have subpoenaed Mr Collins to give evidence at the separate question hearing without joining Gallagher, the Court described that approach as suboptimal.

In the Court's view, joinder was desirable even if Gallagher was not strictly necessary to decide the existing dispute between Hassall Developments and QBE. The proposed claims against Gallagher arose from the same transaction or series of transactions as the existing claims against QBE.

Further, what was said between Ms Pigram of QBE and Mr Collins of Gallagher on 19 July 2022, and what was or was not disclosed to QBE, would need to be determined in order to decide both the existing claim and the proposed broker claim.

Justice Jackman granted leave to join Arthur J. Gallagher & Co (AUS) Limited to the proceeding under rules 9.02(1) and 9.05(1) of the Federal Court Rules. The Court also granted leave for Hassall Developments to file and serve an amended originating application and amended statement of claim by 4 pm on 7 May 2026.

The Court held that joinder was desirable because the proposed claims against Gallagher arose from the same transaction or series of transactions as the existing claims against QBE, and because common factual issues would need to be determined in any event. The nature of the agreement reached on 19 July 2022, and the alleged failure by Hassall Developments to discharge its duty of disclosure, were questions common to both claims.

The Court accepted several practical reasons supporting joinder. Joining Gallagher reduced the risk of inconsistent findings on overlapping factual matters. It was more efficient for the Court and the parties to determine substantial overlapping issues once. Gallagher also had an interest in the outcome of the separate question and the proceedings generally, so it was preferable that it be given the opportunity to participate if it wished.

QBE pointed to prejudice because the separate question hearing would very likely need to be vacated and relisted if Gallagher did not consent to the existing dates. The Court took that prejudice into account, including the issue that QBE's senior counsel was unavailable on alternative dates the judge had indicated. Even so, the Court held that the prejudice did not outweigh the desirability of joinder.

On discovery, the Court ordered QBE to give discovery of the documents within categories 1 to 4 of Annexure A to the interlocutory application by 4 pm on 21 May 2026, together with a verified list of documents. The Court noted that QBE had said the fourth category would yield a nil return, but ordered all four categories in the interests of formality.

For businesses, the most useful point is that disputes about insurance cover often turn on placement-stage communications rather than only on the final policy wording. A short confirmation that cover is “effective” from a date may later be characterised by the insurer as something narrower, such as interim or holding cover. If that happens, the broker's role can become central very quickly.

This case shows how that can occur. Once QBE alleged an oral agreement between its representative and the broker's representative for hold cover pending offer and acceptance, the factual overlap between the insurer dispute and any broker dispute became obvious. Questions about what was said, what was disclosed, and what advice was given could not be neatly separated.

Businesses should also note that a shifting insurer position can have procedural consequences. The Court recorded that QBE's position had evolved from saying cover was provided from 19 July 2022 under the auto-cover scheme, to denying cover was bound on that date, to alleging an oral hold-cover arrangement. Where a position changes in that way, it is important to preserve all earlier correspondence and compare it carefully against later pleadings and evidence.

The decision also highlights the practical importance of broker documentation. If there is any possibility that cover is provisional, interim, subject to acceptance, or dependent on further disclosure, that should be clearly documented and explained to the insured. If it is not, later disputes may involve not only the insurer but also the broker.

Finally, this case is a reminder that courts may prefer to deal with overlapping disputes in one proceeding rather than force parties into multiple cases with a risk of inconsistent findings. That can be efficient, but it also means businesses should think early about whether all relevant parties are already in the case.

The commercial story in this judgment is really about timing, language and records. The dispute was not simply whether there was insurance. It was about when cover was bound, what a confirmation of cover actually meant, and whether there was an oral arrangement sitting behind the written communication.

That is a common pressure point in commercial insurance placements. Businesses often need urgent confirmation that cover is in place, especially for projects, assets or trading risks that cannot wait for every underwriting step to be fully documented. In that environment, shorthand expressions such as “effective from today” can later become contentious if the insurer says the cover was only temporary or conditional.

The judgment also shows why oral communications matter. The alleged conversation between Ms Pigram and Mr Collins became important because it was said to explain the true nature of the 19 July 2022 confirmation. If a business is relying on a broker to arrange urgent cover, it is sensible to ask for written confirmation of any oral arrangement that affects the scope, duration or status of cover.

Another practical point is disclosure. The Court did not decide whether Hassall Developments had been properly advised, but the case shows how disputes about interim cover can intersect with disputes about the duration of the duty of disclosure. Businesses should not assume that a brief confirmation of cover necessarily means all disclosure obligations have ended. If there is any uncertainty, ask the broker and insurer to confirm the position in writing.

From a litigation perspective, this case also illustrates the importance of preserving documents early. Once a dispute emerges, keep not only the final policy and claim correspondence, but also placement emails, underwriting communications, call notes, draft terms and any internal records showing what the business understood at the time. Those materials may become central if the insurer later advances a different account of how cover was bound.

The judgment was delivered on 6 May 2026 by Jackman J in the Federal Court of Australia. It was an ex tempore judgment revised from transcript. The orders joined Gallagher to the proceeding, allowed amended pleadings to be filed, required discovery from QBE, and listed the matter for a case management conference on 13 May 2026.

The reasons also record that a separate question hearing had previously been ordered to commence on 1 June 2026, but that those dates might need to be vacated if Gallagher did not consent to the hearing proceeding then. The judge indicated possible alternative hearing windows in August and October 2026, while noting QBE's senior counsel was unavailable on those dates.

Because this is only an interlocutory judgment, it should be read as a procedural step in a larger dispute rather than a final statement of the parties' rights. The final merits position may depend on later findings about when cover was bound, what was said on 19 July 2022, whether there was misleading or deceptive conduct, and whether any liability could be reduced under section 28(3) of the Insurance Contracts Act.
