Court Shields Cabinet Pages From Lehrmann Diary
Federal Court Justice Brigitte Markovic upheld public interest immunity over two pages of Bruce Lehrmann's diary that relate to Cabinet matters.
Updated on Nov. 2, 2026 in Sex Crimes
Federal Court Justice Brigitte Markovic has upheld a public interest immunity claim over two pages of Bruce Lehrmann's diary, which the Commonwealth says contain information that would breach Cabinet confidentiality if disclosed. The diary was seized during an AFP raid on Lehrmann's Hobart home on 5 June 2024.
Why it matters
The ruling limits Lehrmann's access to material he is seeking as he continues his fight for legal funding, while protecting Cabinet deliberations from disclosure. It also keeps open questions about how federal authorities handled evidence in the investigations involving him.
Justice Markovic ruled that the two diary pages are protected by public interest immunity, and Lehrmann will return to court in December to continue his legal funding fight. Whether the federal police misused information in their investigation is still under examination by Operation Greenough.
The players
Brigitte Markovic
Federal Court justice who upheld the public interest immunity claim over two pages of Lehrmann's diary.
Bruce Lehrmann
Former Liberal staffer and former federal political adviser whose diary, rape allegation litigation and legal funding dispute have drawn sustained national attention.
National Anti-Corruption Commission
Australia's federal anti-corruption agency, which claimed the immunity over the diary pages and dropped its Operation Ivanhoe investigation into Lehrmann.
Australian Federal Police
Australia's national policing agency, whose June 2024 raid on Lehrmann's Hobart home led to the seizure of the diary.
The details
Lawyers for the NACC Commissioner claimed public interest immunity over the two pages after Branko Ananijevski gave evidence that the entries relate to confidential Cabinet committee considerations and a Cabinet decision on costings. Lehrmann sought return of the entire diary, and the court limited its return to pages not subject to the claim.
Timeline
2019: Alleged taking of French submarine documents from Linda Reynolds's office, investigated under Operation Ivanhoe.
5 June 2024: AFP raid on Lehrmann's Hobart home seizes his diary.
12 October: NACC tells Lehrmann it is no longer pursuing Operation Ivanhoe.
2 November 2026: Justice Markovic rules the two diary pages are protected by public interest immunity.
December: Lehrmann returns to court to continue his legal funding fight.
Legal Context
The decision applies the long-standing public interest immunity framework, which protects Cabinet deliberations from disclosure in court proceedings. It shows how that protection can extend to personal records that capture confidential government material.
The ruling determines what material from the diary can be accessed in Lehrmann's ongoing legal funding case. It also clarifies that Cabinet-related content kept in personal records can remain protected from disclosure.
The takeaway
Public interest immunity can protect confidential Cabinet material even when it appears in a private diary, so the outcome of similar disputes may depend on how closely the material is tied to Cabinet deliberations. Readers following the case should watch the December court date for the next development.
What happens next
Bruce Lehrmann is due back before the court in December to continue his fight for legal funding.
