The Offence of Bodily Harm: When a Fight Ends Up in Court

22 January 2026Updated: 

Key Takeaways

  • Medical treatment vs first aid
  • Stitches
  • Loss of an organ
  • Affray

The key to whether a fight ends in a fine or a prison sentence is not how dramatic the injury looks but the medico-legal concept of treatment (Art. 147 CP). If the injury requires only a single instance of medical first aid (cleaning a wound, a plaster, a check-up visit) it is a minor offence, punished with a fine of one to three months. If it also needs medical or surgical treatment with a planned course of healing (prescribed curative medication, a cast, rehabilitation) it is an offence of bodily harm, with prison of three months to three years or a fine. Medically necessary stitches are surgical treatment (minor surgery) even if applied at the first visit, according to settled Supreme Court case law; the defence can dispute whether suturing was objectively necessary. Mere rest or taking generic painkillers is usually not treatment for criminal-law purposes, and mere monitoring of how the injury heals is not (Art. 147.1 CP), and injuries with the loss of an organ or serious disfigurement raise the penalty considerably.

A traffic argument or a fight in a nightclub can end in criminal proceedings for bodily harm. The factor that determines whether you face a fine (a minor offence) or a prison sentence (a basic or serious offence) is not so much how dramatic the bleeding looked, but the medico-legal concept of "treatment".

The Key Concept: First Aid vs. Treatment

Art. 147 of the Criminal Code sets out the difference:

  • Minor offence: where the injury requires only a single instance of medical first aid (e.g. cleaning a wound, applying a plaster, a single visit to the doctor for a check-up). It is punished with a fine of 1 to 3 months.
  • Offence of Bodily Harm (Basic): where the injury requires, in addition to first aid, medical or surgical treatment. This involves an objectively necessary curative course: prescribed curative medication, immobilisation with a cast, rehabilitation; mere monitoring or follow-up of how the injury heals does not count (Art. 147.1 CP). Medically necessary stitches are surgical treatment (minor surgery) even if applied at the first visit, according to settled Supreme Court case law; the defence can dispute whether suturing was objectively necessary. The penalty is 3 months to 3 years in prison, or a fine.

Defence strategy: the prosecution often tries to upgrade a minor injury to an offence on the basis that ibuprofen was prescribed. Mere rest or taking generic painkillers is usually not regarded as medical treatment for criminal-law purposes. Disputing this point with a medical expert is essential to reduce the sentence.

Serious Bodily Harm: Disfigurement

If the injury causes the loss or disablement of an organ or limb, or disfigurement (a visible scar on the face, a permanent limp), the penalty rises sharply: 3 to 6 years (Art. 150) or, if the organ or limb is a principal one or the disfigurement is serious, 6 to 12 years (Art. 149). "Disfigurement" is an aesthetic and social concept. Is a 2 cm scar on the arm disfigurement? Probably not. And on the cheek? It may be disfigurement under Art. 150; whether it is serious, under Art. 149, is far more debatable.

Affray

Where several people take part in a fight and attack one another in a confused manner ("all against all"), the offence of affray applies (where dangerous means are used) even if it is not possible to identify who caused each injury: it punishes the mere fact of taking part in the dangerous brawl, even if you were not the actual author of the blow.

Frequently asked questions

What is the difference between first aid and medical treatment?

First aid is the medical act of treating for the first time (cleaning a wound, applying a plaster, a check-up visit) and gives rise to a minor offence with a fine. Medical or surgical treatment involves an objectively necessary curative course (prescribed curative medication, a cast, rehabilitation) and turns the facts into an offence of bodily harm under Art. 147.1 CP, with prison of three months to three years or a fine; mere monitoring or follow-up of how the injury heals is not treatment. Medically necessary stitches are surgical treatment (minor surgery) even if applied at the first visit, according to settled Supreme Court case law; the defence can dispute whether suturing was objectively necessary.

Does prescribing ibuprofen turn the injury into a serious offence?

Not necessarily. Mere rest or taking generic painkillers is usually not regarded as medical treatment for criminal-law purposes. Disputing this point with a medical expert is essential, because the prosecution sometimes tries to upgrade a minor injury to an offence on the basis of such a prescription.

When are injuries considered serious?

When they cause the loss or disablement of an organ or limb or disfigurement (for example, a visible scar on the face or a permanent limp). In those cases the penalty rises sharply: three to six years in prison (Art. 150 CP) or, if the organ or limb is a principal one or the disfigurement is serious, six to twelve years (Art. 149 CP).

What is affray in bodily-harm cases?

It is the confused fight of several people who attack one another ('all against all') using dangerous means, even where it is not possible to identify who caused each injury. The mere fact of taking part in the dangerous brawl is punished, even if you were not the actual author of the blow.
