Fatal or Injury Workplace Accident: the Concurrence Between Art. 316 and Reckless Homicide

A serious workplace accident almost always opens far more than a single file. When a worker dies or is seriously injured at their post, alongside the investigation by the Labour Inspectorate a criminal case may be set in motion in which the employer, the technicians or the supervisors end up charged. The key legal question is not only whether the safety measures were missing, but what happens in criminal terms when that danger turns into a death or an injury. As criminal lawyers specialising in workplace accidents, we explain how the concurrence of offences between the endangerment offence of arts. 316 and 317 CP and reckless homicide or injuries is structured, and how it is defended.

From the Endangerment Offence to the Result Offence

The starting point is the offence against workers' safety. Art. 316 CP punishes a person who, being legally obliged and in breach of the prevention rules, fails to provide the necessary means for workers to carry out their activity with adequate safety measures, thereby placing their life, health or physical integrity in serious danger. It is an endangerment offence: it is complete once the risk is created, without any accident being required.

The problem arises when that danger materialises. If the lack of measures leads to the death or injury of a worker, the law is not content with punishing the danger: it also pursues the harmful result. And that is where one of the most significant technical questions in this field comes into play, the concurrence of offences.

The Concurrence Between Art. 316 and Reckless Homicide

The settled doctrine of the Supreme Court starts from a simple idea: the endangerment offence of arts. 316 and 317 CP does not absorb the result offence. They protect different legal interests —the collective safety of workers, on one side; the life or integrity of the specific victim, on the other— and, for that reason, they concur.

• If the accident causes the death of the worker, the offence against safety concurs with reckless homicide under art. 142 CP.
• If the accident causes injuries, it concurs with reckless injuries under art. 152 CP, whose penalty varies according to the gravity of the harm.

In practice, courts tend to resolve these situations as an ideal concurrence —a single act that infringes two provisions— precisely so as not to punish the same wrong twice: the danger created and its materialisation in the result form part of one and the same event. The specific characterisation (ideal or real) and its effect on the penalty is one of the areas where the defence is fought.

The Penalties at Stake

It is worth keeping the full penal framework in view, because the accumulation of offences raises the exposure considerably:

• Art. 316 CP (intentional form): imprisonment of six months to three years and a fine of six to twelve months.
• Art. 317 CP (serious negligence): the penalty one degree lower than that of art. 316. It is the most frequent characterisation in practice, because the duty-bearer does not seek the risk, but their serious negligence brings it about.
• Art. 142 CP (reckless homicide): imprisonment of one to four years where the negligence is serious, plus civil liability for the death.
• Art. 152 CP (reckless injuries): a variable penalty depending on the harmful result caused.

To all of this is always added the civil liability arising from the offence: the compensation to the victim or their relatives for the harm suffered.

Who Is Liable: the Duty of Guarantor and Art. 318 CP

The offence is committed only by a person who is legally obliged to ensure safety. That duty of guarantor falls, according to the actual division of functions in each company or site, on the employer and the directors and managers, the prevention technicians, the health and safety coordinators and the supervisors or site managers with decision-making power over working conditions.

Where the facts are attributed to a legal person, art. 318 CP lays down a specific rule: the penalty is imposed on the directors or those in charge of the service who were responsible and on those who, knowing of the facts and being able to remedy them, failed to adopt measures to do so. The court may also order the accessory consequences of art. 129 CP. An effective delegation of functions may shift the liability towards the delegate, but only where it was genuine —with sufficient means, powers and authority— the delegating party retaining a residual duty of selection and supervision.

The Triple Track: Criminal, Administrative and Labour

A serious workplace accident rarely stays within a single file. The usual scenario is that three proceedings open in parallel, with different but connected logics:

• Administrative track. The Labour Inspectorate investigates the incident, draws up a report and may propose penalties for breach of the occupational risk-prevention rules.
• Labour or social-security track. The surcharge on benefits for the lack of safety measures is discussed; it increases the benefits payable by the employer and cannot be insured.
• Criminal track. It pursues the endangerment offence and, where there is a result, reckless homicide or injuries.

These tracks are not watertight: the police report, the Inspectorate's report and the technical reports circulate between them, and what is stated or proved in one may condition the others. That is why it is essential to coordinate the strategy from the outset and not to tackle each front in isolation.

The Family's Private Prosecution

Following a fatal accident or one with serious sequelae, the relatives and injured parties may act as a private prosecution and appear in the case with a lawyer and court agent. From that position they are not mere spectators: they drive the investigation, propose expert prevention evidence, request steps of inquiry to establish the lack of measures and claim civil liability for the death or the injuries.

For the family, having a solid technical defence makes the difference between proceedings that advance with well-directed evidence and others that dissolve. And for the person facing the charge, anticipating the line of the private prosecution is an indispensable part of the strategy.

Lines of Expert Defence

The defence in these proceedings is eminently technical and relies on expert risk-prevention evidence. The lines we examine most frequently are:

1. Documented compliance with the occupational-safety rules. Establishing, with documentation and expert evidence, that the required means were provided, the risks were assessed and the due training and information were given.
2. Breaking the causal link. Showing that the result does not stem from the breach alleged, but from an external cause or the decisive intervention of a third party.
3. Effective delegation of functions. Where prevention was genuinely delegated to technicians or prevention services, liability may shift towards the delegate.
4. The worker's conduct. Only conduct that is unforeseeable, reckless and wholly at odds with the instructions given can exclude the liability of the duty-bearer; ordinary carelessness must be anticipated.
5. Characterisation of the concurrence and of the negligence. Whether the negligence is serious or less serious, and how the concurrence is structured, has a direct impact on the resulting penalty.
6. Repair of the harm. Compensation to the injured parties operates as a mitigating circumstance and facilitates agreements that close the proceedings.

The settled case law of the Supreme Court requires rigorous reasoning both as to the creation of serious danger and as to the causal link with the result, and any deficiency in that reasoning opens a ground of challenge that is worth working on from the start of the investigation.
