Charged Under the WSH Act? Your Defence Options, Explained by a WSH Defence Lawyer

The short answer

A charge under the Workplace Safety and Health Act 2006 is a criminal charge, whether the accused is a company, a director, a WSH officer, a supervisor or a worker. The realistic options are: persuading the prosecution to withdraw or reduce the charge through written representations, seeking composition where available, contesting the charge at trial, or pleading guilty on the best available terms with well-prepared mitigation. Which route is right depends on the evidence, and that assessment should be made early, not on the eve of the plea.

First: understand exactly what is alleged

WSH charges identify a duty holder, a duty, and the measures allegedly not taken. The details matter. Was the accused truly the employer or occupier in law? Were the particularised measures actually reasonably practicable at the time, or are they hindsight? Is the causal link between the alleged failure and the incident sound? A significant number of charges are amended or withdrawn when these questions are pressed with evidence.

Representations: the quiet stage where cases are often won

Before and after charging, defence counsel can make written representations to the prosecuting authorities setting out weaknesses in the case, the true factual matrix, and the duty holder’s safety systems and remedial efforts. Outcomes can include withdrawal, a reduced charge, or an offer of composition. Representations are most effective when supported by documents: risk assessments, training records, maintenance logs, and expert opinions where appropriate.

Contesting the charge at trial

The central battleground in most contested WSH prosecutions is whether the accused did what was reasonably practicable. That inquiry is evidence-heavy: what the risk assessment identified, what control measures existed, how workers were actually trained and supervised, and whether the incident arose from a system failure or a genuinely unforeseeable act. Trials also test causation and identification of the correct duty holder among multiple contractors on a site. A trial is costly and public, so the decision to contest should rest on a sober, documented assessment of the evidence, which we provide in writing before you commit.

Pleading guilty: mitigation is not an afterthought

Where a plea is the right course, sentencing turns substantially on culpability and harm, and on what the offender has done since. Well-evidenced mitigation addresses: the extent of the safety systems that did exist, prompt remedial and rectification measures, cooperation with MOM, compensation and support given to the injured worker or family, and the offender’s safety record. The difference between generic mitigation and properly prepared mitigation is routinely measured in tens of thousands of dollars, and sometimes in whether an individual goes to prison.


Frequently asked questions

The company is being charged. Why do the directors need advice?

Because officers can be personally prosecuted where the company’s offence involved their consent, connivance or neglect. The company’s interests and an individual officer’s interests do not always align, and that should be assessed at the start.

Can we just pay composition and move on?

Composition, where offered, resolves the matter without a conviction and is often sensible. But it is discretionary, not a right, and for serious incidents it is rarely offered. Whether to seek it, and when, is a strategic decision.

Will a conviction affect our ability to tender and hire foreign workers?

It can. Convictions and enforcement actions can affect government tenders, MOM demerit points and work pass privileges. These collateral consequences deserve as much attention as the fine.

How soon should we involve a lawyer?

Before statements are recorded, if possible. The record created during the investigation is the raw material of the prosecution; it is far easier to get it right the first time than to explain it away later.
