freedom of tweet - He said, she said, court said

The litigation in Comcare v Banerji arose from the intersection of public service obligations, online political communication, and statutory workers’ compensation law.

Michaela Banerji was employed by the Commonwealth in the former Department of Immigration and Citizenship.

Background

During her employment, she operated an anonymous Twitter account, @LaLegale, from which she published more than 9,000 tweets. Many of those posts were politically charged and critical of the Department, senior officials, immigration policy, and members of Parliament. Some tweets were published during work hours.

Although the account was anonymous, the content was later attributed to Ms Banerji. Internal complaints were made by other public servants, prompting an investigation under the Public Service Act 1999 (Cth) and the APS Code of Conduct.

In September 2013, Ms Banerji’s employment was terminated on the basis that her conduct breached Code obligations requiring APS employees to act impartially, professionally, and in a manner that upheld public confidence in the Service.

That termination became the catalyst for the subsequent litigation.

Workers’ Compensation Claim – Comcare Determination

Following her dismissal, Ms Banerji lodged a workers’ compensation claim with Comcare. She alleged that her termination caused a psychological injury, diagnosed as an adjustment disorder characterised by depression and anxiety.

Comcare denied liability. It relied on section 5A(1) of the Safety, Rehabilitation and Compensation Act 1988 (Cth), which excludes compensation for injuries arising from “reasonable administrative action taken in a reasonable manner” in respect of employment.

Comcare determined that the termination was lawful disciplinary action and therefore fell within the statutory exclusion. Ms Banerji sought review of that decision.

Administrative Appeals Tribunal – First Turning Point

The matter proceeded to the Administrative Appeals Tribunal. The Tribunal accepted that Ms Banerji had breached the APS Code of Conduct. However, proceeding on its assessment of the constitutional issue, the Tribunal concluded that the termination could not be characterised as reasonable administrative action for the purposes of section 5A(1), because the disciplinary action was said to impermissibly burden the implied freedom of political communication.

The Tribunal did not purport to make a final or binding determination of constitutional invalidity.

Rather, its reasoning operated within the statutory task of determining whether the compensation exclusion applied. On that basis, the Tribunal set aside Comcare’s decision and held that the compensation exclusion did not apply.

This marked the first significant legal divergence in the case. The Tribunal’s approach elevated what had been an employment and compensation dispute into a constitutional question within the confines of its review jurisdiction. Comcare appealed.

Removal to the High Court – Jurisdictional Shift

Following the AAT decision, the matter entered the federal judicial review pathway. Given the centrality of the constitutional question, the proceeding was ultimately removed into the High Court of Australia under section 40(1) of the Judiciary Act 1903 (Cth).

The removal reflected the constitutional dimensions of the dispute. The central issue was no longer whether Ms Banerji breached the Code, but whether the Code itself, and the sanctions imposed under it, were constitutionally valid in light of the implied freedom of political communication.

The High Court was asked to determine whether sections 10(1) (APS Values), 13(11) (conduct inconsistent with APS impartiality), and 15(1) (sanction power) of the Public Service Act 1999 (Cth), taken together, imposed an unjustified burden on political communication, rendering the termination unlawful and invalidating Comcare’s reliance on the statutory exclusion.

High Court of Australia – Final Determination

In Comcare v Banerji (2019) 267 CLR 373, the High Court unanimously allowed Comcare’s appeal.

The Court accepted that the APS Code provisions burdened political communication. However, applying the established Lange framework, it held that the burden was justified.

The Court identified the legitimate purpose of the provisions as maintaining an apolitical, impartial, and professional public service. That purpose was held to be compatible with the system of representative and responsible government mandated by the Constitution.

The measures were found to be reasonably appropriate and adapted to achieving that purpose. The Court rejected the proposition that the implied freedom operates as a personal right capable of invalidating ordinary employment regulation.

Importantly, the Court emphasised that anonymity did not neutralise the impact of Ms Banerji’s conduct. The tweets were capable of undermining public confidence in the APS, regardless of whether her identity was initially concealed.

Having found the termination lawful, the Court concluded that it constituted reasonable administrative action taken in a reasonable manner. Section 5A(1) of the Safety, Rehabilitation and Compensation Act 1988 (Cth) therefore applied, and Comcare was not liable to pay compensation.

The Tribunal’s decision was set aside.

Ultimate Outcome and Legal Reasoning

The final outcome restored the original administrative position. Ms Banerji’s termination was upheld as lawful, constitutionally valid, and sufficient to trigger the statutory compensation exclusion.

The reasoning across jurisdictions reveals a narrowing of focus as the matter progressed.

What began as an employment dispute expanded into a constitutional challenge before ultimately being resolved by reaffirming institutional integrity as a legitimate constraint on individual expression within the public service. The High Court’s decision clarified that the implied freedom of political communication does not displace professional obligations imposed by valid legislation. It also confirmed that disciplinary action, including termination, may lawfully follow sustained online conduct that undermines confidence in government institutions.

Professional Significance

Comcare v Banerji stands as a leading example on the limits of political expression for Australian public servants in the digital era. It establishes that online commentary, even when anonymous and undertaken outside official duties, may have employment and compensation consequences where it conflicts with statutory obligations of neutrality and professionalism.

The case remains a reference point for agencies, advisers, and courts assessing the boundary between personal expression and institutional trust in modern public administration.
