A long and winding road to overturn a July 2025 Federal Court judgment
The Federal Court judgment of Justice Thawley of July 2025
Does the Commissioner of Taxation have a hold over one or more judges of the Federal Court?
The Australian Taxation Office has a well-worn tactic to avoid complying with its Model Litigant Obligation.
Under the Legal Services Directions, Commonwealth entities and their lawyers must act as model litigants, which requires maintaining the highest ethical standards. This includes not requiring another party to prove a matter that the Commonwealth knows to be true.
It is said that "The Commonwealth's obligation to act as a model litigant is codified under Part 5, Division 2 of the Legal Services Directions. This duty ensures [sic, fails to ensure] that the government and its agencies behave with complete propriety, fairness, and honesty in all litigation and civil claims."
In reality it ensues no such thing.
When confronted by a claim supported by evidence that the Commissioner of Taxation has failed to comply with Court orders, hidden material evidence, denied those orders were ever made, and given undertakings to the Court only to rescind those undertakings later, the Commissioner has a path he often treads.
Summary Dismissal and Non-compliance with Federal Court Rules
When in a tight corner where the Commissioner of Taxation that he does not want to admit the truth of allegations, there are exactly three ducks that must line up:
- The Commissioner of Taxation must be permitted by a judge of the Federal Court of Australia to ignore rule 16.07 of Federal Court Rules 2011 and fail to file a defence that is required under that rule.
- The Commissioner of Taxation must be granted an application for summary dismissal of the claims - having not denied the truth of any of the allegations,
- The Federal Court judgment in favour of the Commissioner of Taxation must make findings that there is no question of fact to be determined, and hence summary dismissal is an available option.
It may come as a surprise, but there are some Federal Court judges who go to extraordinary twists of logic, omission, and invention to ensure these three little ducks will line up just as the Commissioner of Taxation wishes. It is almost as though the Commissioner has some invisible and yet powerful sway over the mire some Federal Court judges are prepared to sink into for the sake of a few ducks.
By not filing a formal defence, the ATO avoids the requirements of Federal Court Rule 16.07, which mandates that a party specifically admit or deny every allegation of fact in an opponent's pleading. This "tactical silence" allows the ATO to avoid confirming known facts—such as the existence or concealment of the Higham Minute—without technically making a false statement to the court.
It is a legal principle that if there are questions of fact in issue, then the appropriate place for the addressing these is in a hearing of the evidence - after a defence has been filed. Once a Court identifies any question of fact it is not open to it to summarily dismiss a proceeding. An application for summary judgment cannot be used to make findings of fact regarding evidence; a full hearing of the claims is necessary once findings of fact are required.
Strategic Omission of the "Real Argument"
Both Wigney J and Thawley J avoiding addressing the argument in their judgments — which was based on numbered folio pages from official ATO files. By doing this, the court avoided the necessity of addressing the evidentiary conflict regarding the report's creation date.
During the first summary dismissal hearing for the Tax Commissioner's application, the applicant offered documents demonstrating that a "final report" was not present on Commonwealth files in 1997 though John Higham gave it in evidence on oath in 2007 that he wrote it in 1997. Wigney J did not accept this evidence or consider it in his judgment after the Tax Commissioner's counsel, Ms Firkin KC, stated she "didn't understand the documents" and requested they be excluded.
- The 2007 Waiver Event: The privilege was waived on 2 July 2007 during the Besanko J hearing when the Respondents' counsel tendered the McInnis advice, which explicitly referred to the Burslem advice (the basis for the Higham Minute).
- The Judicial Omission: No statement regarding this waiver is to be found in the judgments of Wigney J and Thawley J. Instead, they focused on Mansfield J's earlier ruling upholding the initial claim of privilege—that no one was contesting before them.
- The Impact: By focusing on the initial claim of privilege rather than the subsequent waiver, the judges effectively provided an answer to a question they were not asked, thereby insulating the Tax Commissioner from the consequences of failing to disclose the document in 2007.
And Then - Tangled Legal Webs That May Never End
- When the application for constitutional writs to the High Court is not accepted for filing without leave of a justice...
- When the application for leave to file application for constitutional writs is refused by the High Court...
- When the application for leave to appeal from the judgment to refuse leave to file application for constitutional writs has been accepted...
Form 23 – Application for leave to appeal
Note: see rule 41.01.1.
IN THE HIGH
COURT OF AUSTRALIA No. of 2026
CANBERRA REGISTRY
BETWEEN: In
the matter of an Application by
COLIN
GEORGE DUNSTAN
for
Leave to Appeal
EX PARTE APPLICATION FOR LEAVE TO APPEAL
The applicant applies for leave to appeal from the judgment of
Edelman J delivered on 13 May 2026 in C7/2026, by which the
learned single Justice refused the applicant’s application under r 6.07.3 of
the High Court Rules 2004 for leave to issue or file a proposed
application for constitutional or other writs.
Special considerations or circumstances: Not applicable
Part I: PROPOSED
GROUNDS OF APPEAL AND ORDERS SOUGHT
1.
The
applicant applies for leave to appeal from the judgment of Justice Edelman on
the following grounds:
1. Elision of distinct
abuse-of-process premises
The learned single
Justice erred in refusing leave to issue or file the proposed application as
manifestly hopeless where the reasons elided two distinct abuse-of-process
propositions:
(a)
that the applicant sought to
relitigate matters already litigated and determined; and
(b)
that the applicant could and
should have raised matters earlier. [1]
The proposed application
directly answered the second proposition by contending that the applicant had
previously attempted to raise the relevant matters, but was opposed by the
respondents and refused leave by the Court. [2]
2. Failure
to address undetermined issues
The learned single
Justice erred in treating the proposed application as mere relitigation without
addressing the applicant’s contention that material issues had not been
determined [3] in the sense necessary to
support the abuse-of-process conclusion, including:
(a)
waiver of legal professional
privilege following disclosure of the McInnis advice;
(b)
allegations of fraud concerning
the “final report” and the proceeding before Besanko J;
(c)
evidence concerning Ms Orr’s
belief that Mr Higham had decided not to charge the applicant and the statutory
requirement for Ms Orr to then recall the applicant to duty; and
(d)
the allegation that Wigney J’s
judgment itself was procured by mischaracterisation of the pleaded case.
The abuse-of-process reasoning
required attention to what had actually been determined, what could reasonably
have been raised earlier, and whether the applicant had been prevented from
raising it. [4]
3. Mischaracterisation
of fraud-on-judgment and the separate fraud pathway
The learned single
Justice erred in treating the proposed application as manifestly hopeless or
abusive without addressing the distinction between:
(a)
relitigating issues determined
by Wigney J; and
(b) alleging that Wigney J’s judgment itself was procured by fraud[5] or material
mischaracterisation of the pleaded case.
The latter allegation
could not have been determined before Wigney J’s judgment existed. Further, in Dunstan
v Morgan [2024] FCA 982, Kennett J had recognised that a separate
proceeding to impeach Wigney J’s judgment for fraud was a legally available
avenue and was not so clearly hopeless that filing-related relief should be
refused. [6]
4. Error
in treating the separate fraud pathway as necessarily abusive or hopeless
The learned single
Justice erred in treating the proposed application as manifestly hopeless or
abusive without addressing the procedural context recognised in Dunstan v
Morgan [2024] FCA 982: namely, that a separate proceeding to impeach Wigney
J’s judgment for fraud was a legally recognised avenue and was not so clearly
hopeless that filing-related relief should be refused.
5. Failure to address
the privilege-waiver non sequitur
The learned single
Justice erred by failing to address that the proposed application identified an
arguable non sequitur in the reasoning below concerning privilege: namely, that
a prior decision upholding an original claim of privilege did not determine a question
whether privilege had been waived later.
2.
The applicant seeks orders:
- Leave to appeal from the judgment of Edelman J delivered on 13 May
2026 in C7/2026.
- The appeal be allowed.
- The order of Edelman J refusing leave to issue or file the
proposed application for constitutional or other writs be set aside.
- The applicant’s application under r 6.07.3 of the High Court
Rules 2004 be remitted or referred for determination by another
Justice of the Court.
- Such further or other orders as the Court considers
appropriate.
Part II: QUESTIONS
ON WHICH LEAVE IS SOUGHT
Issue 1 — r 6.07.3 and characterisation of proposed
application
3.
Whether a single Justice
considering an application under r 6.07.3 may refuse leave to issue or file a
proposed constitutional writ application as manifestly hopeless where the
reasons do not address a central distinction on which the applicant contends the
proposed application is not abusive.
Issue 2 — Abuse of process and undetermined matters
4.
Whether a proposed application
can properly be characterised as relitigation of matters already determined
without identifying whether the matters relied upon were in fact determined, or
whether the applicant was previously prevented from raising them.
Issue 3 — Fraud-on-judgment and failure to determine
real controversy
5.
Whether an allegation that an
earlier judgment was procured by material mischaracterisation of the pleaded
case can be treated as mere relitigation without addressing whether the alleged
mischaracterisation bore upon the foundation of the earlier abuse-of-process
conclusion.
Part III: ARGUMENT
1. This application is narrow
The proposed writ application concerned judgments of the Federal
Court of Australia, including the judgment of Thawley J dismissing the
applicant’s proceeding as an abuse of process and the later judgment of
Moshinsky J refusing leave to appeal. The applicant is conscious of paragraph 6
of the reasons below, which referred to the High Court’s power to make
vexatious proceedings orders. This application does not seek to refile the
proposed Form 12 or reargue the whole underlying dispute. It is confined to whether
the single Justice erred in refusing leave to issue or file the proposed
application as manifestly hopeless under r 6.07.3.
2. The central difficulty in the reasons
The reasons below treat the proposed
application as an attempt to relitigate matters already determined. That
characterisation elides two different propositions: first, that matters have
already been litigated and determined; secondly, that matters could and should
have been raised earlier.[7]
The applicant’s proposed application answered
the second proposition. It contended that he had previously attempted to raise
the relevant matters, but was opposed by the respondents and refused leave by
the Court. That answer was material to whether the proposed application was
manifestly hopeless, abusive, vexatious or outside jurisdiction.[8]
3. The proposed application identified
undetermined issues
The proposed application did not merely
complain that previous courts had reached adverse conclusions. It contended
that material issues had not been determined at all. Those issues included
waiver of privilege, allegations of fraud, evidence concerning Ms Orr’s
belief that Mr Higham had decided not to charge the applicant, and the
allegation that Wigney J’s judgment itself had been procured by
mischaracterisation of the pleaded case.
The abuse-of-process reasoning therefore
required attention to what had actually been determined, what could reasonably
have been raised earlier, and whether the applicant had been prevented from
raising it.[9]
The reasons below did not undertake that analysis.
4. Fraud-on-judgment was not merely
relitigation
The proposed application alleged that Wigney
J’s judgment itself was procured by fraud. That allegation could not have been
determined before the judgment existed. It was therefore not enough to
characterise the application as relitigation of matters already decided.
Nor was it sufficient to say that any fraud was
immaterial because Wigney J’s proceeding was in any event an abuse of process.
That reasoning assumes the abuse-of-process conclusion was independently
correct. But the proposed application alleged that the fraud or mischaracterisation
bore directly upon the foundation of that conclusion.
The applicant does not rely on LVR (WA) Pty Ltd v Administrative
Appeals Tribunal as an authority on fraud. It is relied upon for a narrower
proposition that substantial adoption of one party’s position may evidence a
failure to bring an independent mind to bear on the issues required to be
determined.[10]
The relevance of LVR here is not that copying or adoption proves
dishonesty. The relevance is that, where the adopted position is said to
mischaracterise the opposing party’s pleaded case, the question becomes whether
the judgment determined the case actually pleaded or instead determined a case
as characterised by the opposing party.
That distinction matters at the r 6.07.3 stage. If the proposed Form
12 application alleged that the Federal Court adopted a material
mischaracterisation of the pleaded case, the application could not be dismissed
as manifestly hopeless merely by treating that allegation as ordinary
relitigation. The issue was whether the proposed application disclosed an
arguable failure to determine the real controversy, not whether LVR itself
established fraud.
5. Kennett J’s judgment
reinforces arguability
The applicant relies on Dunstan v Morgan as an authority for
the legal availability and arguability of a separate fraud proceeding, not as
additional evidence outside the material before the learned single Justice.
Kennett J had earlier held that it was
erroneous to proceed on the basis that appeal was the only means by which
Wigney J’s judgment could be impugned, and recognised that a separate
proceeding to impeach a judgment for fraud may be appropriate. His Honour
further held that although the proposed fraud proceeding had difficulties, it
was not so clearly hopeless that relief should be refused.
That history does not determine the present
application, but it shows why the proposed writ application could not safely be
characterised as manifestly hopeless without engaging with the distinction
between relitigation and fraud on the judgment itself.
Why leave should be granted
6.
Leave should be granted because
the proposed appeal raises a narrow procedural question of principle concerning
the operation of r 6.07.3:
1.
Where a proposed constitutional
writ application is refused at the filing stage as manifestly hopeless, must
the single Justice’s reasons engage with the central distinction on which the
applicant says the proposed application is not abusive?
7. The issue matters because a refusal under r 6.07.3 prevents the
proposed application from being filed at all.[11] It is not a merits appeal
from every adverse decision. It is a narrow challenge to whether the
leave-to-file refusal was made on a
characterisation that failed to engage with the proposed application’s central
premise.
8.
This question of principle
warrants consideration by this Court.
9.
Leave should be granted.
Part IV: COSTS
10. If the application is refused, the applicant asks that there be no
order as to costs. The application is brought by a self-represented litigant
and raises a narrow procedural question concerning the operation of r 6.07.3
and access to the Court’s original jurisdiction. The applicant does not seek to
refile the proposed Form 12 application in this proceeding.
