The Federal Court just answered whether HR can be sued for documenting performance issues
Three HR managers faced personal defamation lawsuits after documenting performance concerns during a probation review. The Federal Court dismissed the case entirely.
Sandy Aye, Lauren Laidlaw, and Elisa Iurato from World Vision Australia were sued by Josiyas Mbuzi following his probation termination in October 2023. On January 30, 2026, the Federal Court ruled on whether performance feedback given during probation could constitute serious harm to reputation under Australian defamation law.
The situation unfolded on September 20, 2023, when Aye and Laidlaw met with Mbuzi via video link for a probation check-in. According to court documents, Aye told Mbuzi she had received complaints from his Queensland team leaders and workmates about his "bad behaviour" and that this behaviour had negatively impacted others. Laidlaw made similar statements during the same meeting.
Six days later, Aye sent an email to Mbuzi summarizing the discussion, copied to Laidlaw and manager Brent Stahlhut. The email addressed "tone and language used towards leadership" noting "we spoke through various examples of where it was felt that the tone and language used is not aligned with the behaviours of WVA, and that your directness has had an impact on others." It also stated, "Given the feedback from the team and myself, we ask that you be mindful of your tone and language when communicating by email or in person."
Mbuzi was terminated on October 24, 2023, with Stahlhut's letter stating the decision was based on ongoing conduct and communication issues, noting that expectations for improvement were provided but "we did not see an improvement to your communication."
Mbuzi sued all three HR managers personally, claiming the statements were false, defamatory, and made with malice. He alleged the publications suggested he was badly behaved, lacked minimum standards of conduct, was unfit for work, lacked good manners, and was untrustworthy. He further claimed the defamation caused such serious harm that he lost a permanent full-time job he intended to keep for ten to twenty years.
The respondents sought summary dismissal, arguing Mbuzi had no reasonable prospect of proving the publications caused serious harm to his reputation, a threshold requirement under Section 10A of the Defamation Act 2005.
Justice Rangiah agreed. The court found the imputations, while not trivial, "cannot be regarded as grave or serious." Critically, the September 20 statements were only published between Aye and
Laidlaw to each other. Because Mbuzi alleged the two had conspired to make false claims, the court noted the statements fell within a category of publications made to people who don't believe them.
Regarding the September 26 email copied to Stahlhut, the court found no evidence it caused the termination. Stahlhut's letter made clear the decision came a month later based on Mbuzi's failure to improve his conduct after being given the opportunity to do so.
The November 14 email from Iurato stating "your behaviour fell short of the minimum standards of conduct we require at World Vision" was sent only to Mbuzi himself. Since it wasn't published to any other person, that claim failed entirely.
The court emphasized that under the serious harm requirement, defendants are only responsible for harm caused by the specific publication being sued upon, not other communications or consequences. Justice Rangiah concluded Mbuzi had "no reasonable prospect of successfully prosecuting his proceeding for defamation" and dismissed it with costs.
The decision shows that internal performance management communications, particularly during probation, benefit from significant protection when publication remains limited to relevant managers and the feedback addresses workplace conduct rather than character.
