Psychosocial
Legal Precedents
These landmark Australian cases define the boundaries of your duty of care. Understanding them is the first step in building a defensible safety culture.
Court
High Court of Australia
Koehler v Cerebos Australia Ltd
The case that shielded employers for 17 years.
A part-time sales rep made repeated complaints to her employer that her workload was unmanageable. She continued showing up. She never visibly broke down. There was no psychiatric crisis — just an employee telling her employer, over and over, that something was wrong.
The High Court held that workload complaints alone were insufficient to trigger a duty of care. Without a visible, foreseeable psychiatric injury — an observable breakdown, not just reported stress — the employer had no legal obligation to act. Foreseeability required more than words.
THE DANGEROUS TAKEAWAY — NOW OVERTURNED
"Complaints without collapse aren't your problem. That's what practitioners took from this case — and exactly what Kozarov dismantled."

High Court of Australia
Kozarov v State of Victoria
A landmark ruling that shifted the duty from reactive to proactive.
A solicitor in the Specialist Sexual Offences Unit suffered psychiatric injury due to vicarious trauma from her workload. The employer argued they weren't on notice because she hadn't explicitly 'flagged' her distress.
The High Court ruled that for inherently high-risk work, an employer has a proactive duty to identify risks and implement controls—even if the worker hasn't shown signs of injury yet.
The Lesson for Practitioners
"You cannot wait for a complaint. You must have an active, documented risk identification process in place today."
Exposure Indicator / Applies to:
Any role with foreseeable psychological risk — emergency services, healthcare, legal, FIFO, customer-facing.
Court
Regulatory Prosecution
SafeWork NSW v Western Sydney LHD
Formally identifying 'The Way We Work' as a WHS hazard.
The regulator prosecuted a health district for failing to manage psychosocial risks during the handling of internal grievances and complaints, alleging it exposed nurses to psychological harm.
Established that 'organisational justice'—specifically how grievances are handled—is a legitimate WHS hazard that must be controlled under the Act.
The Lesson for Practitioners
"Your grievance handling and conflict resolution aren't just HR tasks; they are WHS control measures."
Exposure Indicator / Applies to:
Every worker grievance or internal conflict currently being managed.
Court
County Court of Victoria
Court Services Victoria (CSV)
The first major criminal conviction for failing to manage mental health like physical safety.
A senior lawyer was exposed to traumatic materials, inappropriate behaviors, and unmanageable workloads. Sadly, this led to a workplace suicide. CSV admitted to failing to identify or assess the psychosocial risks.
CSV was convicted and fined $379,157. The judge emphasized that 'psychosocial hazards are as crucial as physical ones' and failure to manage them has criminal consequences.
The Lesson for Practitioners
"A gap in your Risk Register isn't just an HR issue—it's a criminal WHS liability."
Exposure Indicator / Applies to:
All organisations with high-pressure, high-trauma workloads or known cultural hazards.
Court
Supreme Court (High Payout Damages)
Elisha v Vision Australia
A $1.44 million reminder that process matters.
An employee was dismissed following a botched disciplinary process that failed to follow the organization's own documented procedures and procedural fairness standards.
The court awarded $1.44 million in damages for psychiatric injury caused by the breach of contract and the psychological harm of the unfair process.
The Lesson for Practitioners
"Organisational Justice (fairness, transparent process) is a safety requirement. If you don't follow your own procedures, you are exposed."
Exposure Indicator / Applies to:
Any employer currently managing disciplinary processes or performance plans.
Court
NSW Personal Injury Commission
Ahmadi v New Evolution Ventures
Proof that restructures are high-risk WHS events.
A long-serving manager suffered depression and anxiety after a 'shocking' and non-transparent redundancy process that lacked proper consultation and support.
The commission upheld the workers' compensation claim, finding that the botched management of the change process was the direct cause of the psychological injury.
The Lesson for Practitioners
"Change Management is a high-risk activity. Restructures require a documented psychosocial risk assessment."
Exposure Indicator / Applies to:
Any employer currently planning or executing a restructure or redundancy.
