Perry v NetRatings Australia Pty Limited

Perry v NetRatings Australia Pty Limited [2025] FCA 1404 is a Federal Court interlocutory decision about whether a dismissed employee should be urgently reinstated before the main case is heard. The employee foreshadowed a general protections claim under the Fair Work Act. The employer said it had terminated her after issues arose during an investigation into alleged unauthorised data activity and the return of company devices.

Justice Raper held that there was a serious question to be tried, although the case as then put was not a strong one. Even so, the urgent application failed because the balance of convenience favoured the employer. For business owners, the case is a practical reminder that urgent workplace disputes often turn on process, evidence and timing, not just on the underlying allegation.

Nielsen was described as a data analytics and market research firm. Ms Perry had worked there for around 30 years and had held very senior roles, including Managing Director and later Cluster Leader, Pacific. The court noted that her most recent role was itself described as a managing director position. That seniority mattered in two ways. First, it explained why she had access to sensitive business information and devices. Secondly, it was relevant to her argument that losing the role would make it difficult to obtain comparable employment quickly.

The dispute began when Nielsen alleged that, on or around 24 October 2025, Ms Perry engaged in unauthorised data activity involving suspicious downloads and uploads of Nielsen files and documentation to an external cloud account. Nielsen said that, if true, the conduct would breach her contractual and legal obligations regarding confidentiality and intellectual property. It then conducted a forensic investigation.

On 30 October 2025, Nielsen directed Ms Perry to return three company devices by the next day for the purposes of the investigation. On 31 October 2025, Nielsen terminated her employment. Nielsen said the reason for termination was that she failed to return one of the three requested devices.

Ms Perry moved quickly to court. No pleadings had yet been filed. She sought urgent interlocutory relief compelling Nielsen to reinstate her to her former employment while the substantive case was prepared and heard. Her foreshadowed claim was that Nielsen had taken unlawful adverse action against her.

Ms Perry said Nielsen had taken adverse action against her in three ways: by pursuing the allegations, by placing her on administrative leave during the investigation, and by terminating her employment. She advanced two prohibited-reason arguments.

First, she said the allegations and stand down occurred because of her marital status. Her husband, Mr McMahon, had also worked for Nielsen and his employment had been terminated on 14 October 2025. Ms Perry argued that she was being targeted because she was married to a person who was in conflict with the company, and that marital status is a protected attribute under s 351(1) of the Fair Work Act.

Secondly, and alternatively, she said the termination occurred to prevent her from obtaining legal advice. The reasons record that on 30 October 2025 she requested more time to respond to the allegations, having initially been afforded six hours to do so, and foreshadowed an intention to obtain legal advice. Nielsen agreed to allow her until Monday, 3 November 2025 to respond, but terminated her on Friday, 31 October 2025. Ms Perry argued that the timing supported an inference that Nielsen sought to avoid procedural fairness and prevent her from obtaining legal advice that might have undermined the basis for termination.

The immediate question was not whether Nielsen had definitely breached the Fair Work Act. The question was whether the court should make an interim order compelling Nielsen to reinstate Ms Perry before the substantive case was pleaded, tested and heard.

The court said the relevant test was not in dispute. To obtain interim reinstatement, Ms Perry had to show two things. First, there had to be a serious question to be tried as to whether she was entitled to final reinstatement. Secondly, the balance of convenience had to favour making the interim order now.

That two-step structure matters. A business can lose the first argument and still win the application overall. In other words, even if an employee shows an arguable general protections case, the court may still refuse urgent reinstatement if the practical and evidentiary factors do not support it.

Justice Raper accepted that there was a serious question to be tried, but made clear that the case was not a strong one on the material then available. The court emphasised that no pleadings had yet been filed and that it was not possible, or permissible, to reach final views without fuller affidavit evidence and cross-examination.

On the marital status argument, the court accepted there were potential difficulties. Nielsen argued that the complaint was really about the specific characteristics and conduct of Ms Perry's husband as a former employee in conflict with the company, rather than about her general status as a married person. The court noted that any claim under s 351 had to be directed to marital status and also noted that s 351(2) curtailed the operation of s 351(1).

On the legal advice argument, the court also accepted that there was likely to be significant argument and a need for precision. The authorities showed that asserting a right to seek legal advice in the abstract may be insufficient. However, the court considered there was some evidence that the request for legal advice related to assertions of rights connected with the allegations letter, which had said that the alleged conduct, if true, would constitute a breach of Ms Perry's contractual and legal obligations regarding confidentiality and intellectual property.

Taking those matters together, the court held that, while not a strong case, there was a serious question to be tried as to whether Nielsen engaged in the alleged adverse action for one or more prohibited reasons.

After finding a serious question to be tried, the court turned to the balance of convenience. This was the decisive part of the application. The reasons available show that Ms Perry relied on five matters in support of urgent reinstatement, and the court began addressing them in turn.

First, Ms Perry relied on the strength of her case. The court rejected that as a factor weighing in her favour because, for the reasons already given, the case as currently articulated was not a strong one.

Secondly, Ms Perry argued that if the termination remained in place it would seriously affect her ability to meet financial obligations, including caring for her dependent children. The court was not satisfied on the evidence then before it. Justice Raper noted that the evidence about Ms Perry's circumstances came from her legal representative, that there was information about impacts but without a solid factual base, and that there was no evidence of Ms Perry's actual financial position. The court also noted that Ms Perry had held very senior positions for a long time, but there was no specificity about what the financial impact would be or how wide-ranging it would be. On that material, the court was not satisfied that her financial position weighed in favour of making the order.

The formal orders dismissed the urgent interim application and provided that there be no order as to costs. The judgment therefore stands as an example of a case where an employee cleared the arguable-case threshold but still failed because the practical case for immediate reinstatement was not made out.

For employers, this is best read as a process-heavy employment case rather than a final ruling on data misuse or intellectual property rights. The court did not determine whether Ms Perry in fact engaged in unauthorised downloads or uploads, whether confidentiality obligations were breached, or whether Nielsen ultimately acted lawfully. Instead, the court examined whether the employee had shown enough to justify being put back into a senior role immediately, before the main case was properly framed.

The practical point is that when a business suspects misuse of confidential information, the dispute can quickly become about both substance and process. Substance concerns what happened to the files, systems or devices. Process concerns how the business investigated, what deadlines it imposed, whether the employee had a fair opportunity to respond, whether legal advice was sought, and what reason the business actually relied on when taking action.

Businesses should also note the speed at which these matters can move. Here, the proceeding was commenced urgently and the employer had to defend its process almost immediately. Even though the application failed, the employer still had to explain its actions in court at an early stage. That is a strong reason to have a basic investigation protocol ready before a crisis arises.

Several features of the record are worth noting for practical purposes. Nielsen's allegations were framed around suspicious downloads and uploads of company files and documentation to an external cloud account. The allegations letter also linked the conduct, if true, to contractual and legal obligations regarding confidentiality and intellectual property. Nielsen then directed the return of three devices for forensic investigation and later said termination occurred because one device was not returned.

On Ms Perry's side, the timing of her request for more time and foreshadowed legal advice became part of the case theory. She argued that the termination on 31 October 2025, despite an extension to 3 November 2025, supported an inference about the employer's reasons. Whether that argument will ultimately succeed is a matter for the substantive case, but the interlocutory decision shows how correspondence, deadlines and decision timing can become central evidence.

For business owners, that means letters, emails, device return directions, investigation notices and internal decision records should be drafted carefully. If the real reason for action is failure to comply with a device return direction, say so clearly and ensure the evidence supports it. If the concern is suspected misuse of confidential information, identify the conduct and preserve the forensic trail.

These steps will not eliminate risk, but they put a business in a much stronger position if urgent court proceedings follow. The case shows that courts will look closely at both the legal theory and the practical evidence available at the time urgent relief is sought.

The application was heard on 13 November 2025. Justice Raper made orders the same day dismissing the urgent interim application. Reasons were published on 17 November 2025. The decision records that no pleadings had yet been filed at the time of the interlocutory hearing, so the substantive dispute remained to be developed after this urgent application was decided.

That procedural posture is important. This judgment should be read as an early-stage ruling on interim relief, not as the final word on the parties' rights or on the underlying allegations about data activity, confidentiality, intellectual property or device return.
