Criminal liability of the head of establishment: the personal duty of safety cannot be delegated without control

Imagine: you own a small joinery workshop in Les Mureaux. One morning, your employee starts the conveyor without activating the audible warning, as the regulations require. Another worker, on the beam, is injured. Your first reaction? "It's not my fault, it's the employee who didn't follow the instruction." Grave mistake.

This decision of the Court of Cassation of 4 January 1984 is a classic that has shaped decades of litigation. It answers a crucial question: can the head of establishment (or the director) hide behind the fault of a subordinate to escape criminal liability? The answer is no, with one condition.

What this ruling teaches us is that worker safety is a personal obligation of the head of establishment. He can only discharge himself by proving that he entrusted this mission to a competent employee, with authority and means. Otherwise, he remains criminally liable, even if it was an employee who committed the fault. A lesson that also applies to landlord owners and managing agents, as we shall see.

The facts: a story that happens every day

In this case, an accident occurs in a company. A conveyor transports beams. An employee, responsible for safety, restarts the conveyor without activating the mandatory audible warning. Another worker is injured. The head of establishment is prosecuted for unintentional injuries and breaches of safety rules.

Before the Court of Appeal, he pleads not guilty: the accident is due to the fault of the employee himself, who neglected to use the warning device. The court acquits him. But the Court of Cassation quashes the judgment: the lower judges should have verified whether the head of establishment had delegated his powers to a competent employee provided with the necessary means. In this case, the employee in charge of safety had committed a fault, but that did not exonerate the director from his own obligation to personally ensure compliance with the rules.

The judicial path is classic: criminal court, court of appeal, then cassation. What is striking is that the decision rests on a concrete assessment of the facts: the delegation of powers is not a formality, it must be effective. A simple "you are responsible for safety" on a piece of paper is not enough.

The reasoning of the court — dissected

The Court of Cassation relies on Article L. 263-2 of the Labour Code (now codified in Article L. 4741-1 of the Labour Code, but the principle remains). This text imposes on the head of establishment the duty to personally ensure the application of safety rules. In other words, he cannot say "it's not me, it's the other" without proving that he did what was necessary for the other to be effectively capable of fulfilling this mission.

The reasoning is clear: the employee's fault does not erase the personal obligation of the head. He must demonstrate that he delegated his powers to an employee invested by him, competent, and endowed with the authority and necessary means to effectively ensure compliance with the applicable provisions. In this case, the Court of Appeal had dismissed the prosecution solely on the ground that the accident was attributable to the employee's fault, without addressing this delegation. Error.

This decision is not a reversal, but a confirmation: delegation of powers is a strict exception. It must be real, not fictitious. Judges check on a case-by-case basis whether the delegate had the technical competence, hierarchical authority and material means. A delegation to a simple executor without decision-making power is worthless.

What this changes for you — concretely

For a landlord owner: you rent a commercial premises or a warehouse to a company. If an accident occurs on the premises and you have not complied with your safety obligations (maintenance, compliance), you could be prosecuted. But if you have delegated management to a managing agent or manager, you must ensure that he has the skills and means. In Saint-Germain-en-Laye, an owner was convicted because his managing agent had not had the electrical installation checked, and a tenant was electrocuted. The owner invoked the fault of the managing agent, but the court held that he had not verified his skills.

For a tenant: if you are injured in premises you rent, you can sue the owner for lack of maintenance, but also the head of establishment of the neighbouring company if the danger comes from its activities. But be careful: if the owner has delegated safety to a third party, he may try to exonerate himself. Check who the real responsible party is.

For a co-owner: the managing agent is the legal representative, but the co-ownership council must supervise. If an accident occurs in the common parts (for example, a fall due to lack of maintenance), the managing agent may be prosecuted if he has not correctly delegated safety tasks. Do not rely on the agent without control.

Numerical example: a workplace accident costs a company an average of €50,000 (medical expenses, compensation, fines). A well-structured delegation of powers can reduce the criminal risk, but not eliminate it if it is insufficient.

Four tips to avoid this type of dispute

• Draft a written and precise delegation of powers: it must name the delegate, describe his missions, and mention his skills, authority and the means made available. Do not settle for a general clause in the employment contract.
• Train and inform regularly: the delegate must be trained in the specific risks of the company and update his knowledge. Organise annual sessions.
• Monitor execution: do not completely discharge yourself. Set up internal audits, safety meetings. If the delegate commits a fault, you may be held responsible if you have not checked.
• Document everything: keep evidence of the delegation, training, checks. In case of dispute, it is up to you to prove that the delegation was effective.

Further details: related case law and developments

This decision is part of a consistent line. For example, the ruling of the Criminal Chamber of 13 December 1994 (No. 93-84.345) specified that the delegation of powers must be "effective and not fictitious". More recently, the Social Chamber recalled that the employer can only delegate his criminal liability in safety matters if he has given the delegate the means for his missions (Cass. soc., 28 November 2018, No. 17-18.549).

The trend is towards strengthening personal liability. Courts require an increasingly formalised and controlled delegation. This means that for landlord owners and managing agents, simply entrusting management to a professional is not enough: you must verify his skills and actions. The future? Probably a stricter obligation of result for heads of establishment, with delegation almost impossible to prove in small structures.

Key points to remember

• The head of establishment is personally responsible for safety. He cannot invoke an employee's fault to exonerate himself.
• Delegation of powers is an exception. It must be proved by the person invoking it: competence, authority, means.
• An accident is costly. Beyond the human damage, the financial and criminal consequences are heavy.
• Anticipate. Draft a delegation, train, monitor, document.
