Judge Ralph Perdriau: The Judge Who Walked Into the Mines

On 1 July 1926, the newly created Workers' Compensation Commission began its work in New South Wales. The legislation that created it had already received Royal Assent earlier that year. Parliament had debated the Bill. Speeches had been made. The legal framework was in place.
The more difficult task was only just beginning.
Could a new system earn the confidence of the people it was created to serve? At the centre of that challenge stood a man whose name has largely faded from public memory.
Judge Ralph Joseph Perdriau.
Today, few Australians would recognise his name. Yet contemporary newspaper reports suggest he became one of the principal architects of modern workers' compensation in New South Wales—not only because he helped draft the legislation, but because he was entrusted with bringing it to life.
More than a lawyer
Perdriau's journey to the bench was unusual. After leaving school, he worked on a dairy farm near Camden before entering the New South Wales Public Service. His early career included the Government Architect's Department and later the Department of Mines and Agriculture, exposing him to industries that shaped the state's economy.
When the Workmen's Compensation Act was introduced in 1916, he became Compensation and Legal Officer within the Department of Labour and Industry. Over the following decade he immersed himself in workers' compensation law, researched overseas systems, completed his law degree and was admitted to the Bar.
According to The Sydney Morning Herald, Labour Minister J. M. Baddeley later asked Perdriau to draft a workers' compensation bill that would "make history."
The newspaper reported that it did.
The reforms expanded compensation, introduced compulsory insurance, recognised journey claims and established a specialist Workers' Compensation Commission.
Remarkably, the man who helped draft the legislation was then appointed to lead the Commission responsible for administering it.
Understanding work
What emerges most strongly from contemporary newspaper reports is not simply Perdriau's legal expertise.
It is his apparent determination to understand the work itself.
Writing on his retirement in 1950, The Sydney Morning Herald described him as an expert in miners' compensation cases who had become popular among miners because he studied their problems "at first hand."
The article continued:
"He always insisted, whenever possible, on inspecting the job, often taking his place beside the man at work."
It is a striking image. Rather than relying solely on courtroom evidence, Perdriau appears to have believed that understanding dangerous work required seeing it for himself.
The historical record suggests he visited mines and workplaces whenever possible before deciding the consequences of injuries sustained there.
Whether that approach shaped every judgment is impossible to know. What it does reveal is a judge prepared to leave the courtroom in order to better understand the workplaces that came before it.
Places like Lithgow
Few places better represented the industrial New South Wales his Commission served.
Lithgow's coal mines powered industry.
Its steelworks helped build a nation.
Its quarries supplied stone for expanding towns and cities.
Places like Lithgow also remind us that industrial Australia was not built by men alone. During the Second World War, women entered factories such as the Lithgow Small Arms Factory in large numbers. Their story belongs to the wider history of work and risk, even if Perdriau’s documented reputation was most clearly connected to miners’ compensation.
From 1912, the Lithgow Small Arms Factory became one of Australia's most significant defence manufacturing sites. During the Second World War, thousands of men and women worked there, many undertaking dangerous and highly skilled work in support of the war effort.
These were the kinds of workplaces that gave meaning to the legislation Perdriau had helped create.
Behind every person stood a family.
Behind every workplace stood a community whose prosperity often depended upon dangerous work.
A system finding its feet
The early Commission did not escape criticism. Contemporary reports record debate about its procedures and the way the new system operated.
The Sydney Morning Herald later observed that criticism directed at the Commission in its early years gradually gave way to greater public confidence as applicants experienced what it described as fair treatment.
By the time Perdriau retired in 1950, he had become recognised internationally as an authority on workers' compensation. The newspaper reported that the legislation he helped draft had been cited in other countries and noted that comparatively few of his decisions had been overturned on appeal.
Those achievements tell only part of the story. The image that lingers is not of a judge behind a bench.
It is of a judge standing beside a miner, watching the work before judging its consequences.
Reflection
The early workers' compensation system was shaped by governments, employers, unions, lawyers, judges, doctors and, above all, the workers and families whose lives were changed by injury. Many of their experiences differed. Many of the debates that surrounded the system in 1926 continue in different forms today.
Reading about Ralph Perdriau a century later raises an interesting question. Contemporary newspapers describe a judge who insisted on visiting workplaces, inspecting mines and standing beside workers to better understand the jobs they performed. Whether that approach influenced every decision he made is impossible to measure. Yet it suggests a belief that understanding work required more than reading files.
One hundred years later, Australia's workplaces have changed dramatically. Heavy industry no longer dominates many communities. Psychological injuries now sit alongside physical ones. Technology has transformed the nature of work itself.
Yet one question remains.
How well can we understand the consequences of work if we no longer understand the work itself?
That question sits at the heart of Shattered.
The documentary does not attempt to provide answers. Instead, through conversations with historians, workers, families, health professionals and others, it continues a conversation that began long before us—a conversation about work, responsibility, recovery and what we owe one another when work changes a life.
