Homicide of the consenting person involves a fact very different from a simple family conflict, a healthcare choice, or a written statement on the end of life: one person causes the death of another who has expressed their consent. Doubt often arises right here. Does an explicitly expressed consent make the act lawful? Does anything change if the deceased is seriously ill, if they left a message, or if the act takes place within a care context?
I will explain the boundaries set by Article 579 of the criminal code, why consent affects the classification of the offense but does not automatically eliminate liability, and where the line is drawn between homicide of the consenting person, refusal of medical treatments, and assisted suicide. These distinctions are essential because a materially similar act can have a very different legal meaning depending on who performs the final act, the conditions of the person, and the path followed.
Consent does not make another person's life available
Article 579 c.p. punishes anyone who causes the death of a person with the latter's consent. The penalty provided is imprisonment from six to fifteen years. Therefore, it is incorrect to think that a request, an oral authorization, a letter, or a signed document makes it lawful to directly cause the death of someone who expressed that will. Consent distinguishes this figure from ordinary homicide, but it does not cancel the crime.
The Constitutional Court has clarified that Article 579 configures an autonomous offense and that, in this matter, the consent of the injured party does not operate as a general justification. In other words, consent can reduce the penalty provided by law compared to ordinary homicide, but it does not in itself transform the killing into a permitted conduct. The reference is found in Constitutional Court judgment no. 50 of 2022, which reconstructs the text of Article 579 and its protective function.
For the crime to be conceivable, it is not enough for a person to die after speaking about their suffering or the desire not to continue treatment. It is necessary that another person has caused death and that there is a concrete link between the conduct held and the event. The decisive fact is who performs the causal action, not just the content of the will manifested by the deceased.
A different penalty does not mean a fact without consequences
Homicide of the consenting person is punished less severely than ordinary homicide because the victim's consent is relevant in the legislative assessment of the fact. However, this does not authorize considering it a form of private assistance in dying. The rule does not require consent to be gathered in a specific formula to make the act lawful: in fact, no private formula can replace criminal law.
Article 579 also excludes the common aggravating circumstances provided by Article 61 c.p.; this rule concerns the treatment of homicide of the consenting person, it does not cancel the need to ascertain every element of the fact. When consent is missing, was improperly obtained, or cannot be considered valid, the affair may exit the perimeter of Article 579 and fall back into the provisions on homicide.
When consent is invalid or does not protect against the most serious charge
Not every manifestation of will counts as relevant consent for the purposes of Article 579. The third paragraph of the provision mandates the application of provisions relating to homicide when the act is committed against a person under the age of eighteen, against an infirm person or someone in a condition of mental deficiency due to another infirmity or the abuse of alcohol or narcotic substances, or when consent was extorted by violence, threat, or suggestion, or obtained by deception.
These hypotheses show why it is not sufficient to exhibit a message, an audio, or an apparently explicit statement. Effective freedom of decision matters. Family pressure, a threat, a trick, or a psychological condition affecting the capacity to understand and determine oneself can deprive consent of the meaning attributed to it.
Age of majority alone does not close the question. An adult can go through a phase of confusion, depend heavily on their caregiver, take substances altering the choice capacity, or suffer particularly incisive suggestion. This does not mean every fragility automatically invalidates a will; it means instead that concrete fragility enters the judgment on the genuineness of the request and the correct criminal qualification of the fact.
Documents and messages: useful, but not decisive
A will, a letter, a chat, or a recording can help reconstruct what the person thought or asked. However, they do not have the power to authorize a third party to cause their death. Their meaning depends on the context: date, continuity of will, psychological and physical conditions, any pressures received, relationship with the intervening person, and specific content of the phrases used.
A healthcare declaration and a request to be killed do not coincide. Advance healthcare directives, for example, concern decisions on medical treatments in the event of future incapacity; they are not a mandate directed at another person to cause death. Confusing the two levels can produce very serious criminal consequences.
Refusing treatment is not homicide of the consenting person
The patient can refuse or revoke medical treatments, even when necessary for survival, if capable of acting and receiving adequate information. Law no. 219 of 2017 regulates informed consent, refusal, and revocation of treatments, requiring the doctor to respect the will expressed by the patient within the limits set by law. The same discipline considers artificial nutrition and hydration as medical treatments. You can read the text of Law no. 219 of 2017 published in the Official Gazette.
The difference is not merely linguistic. In refusing treatment, the person exercises a therapeutic choice: deciding not to start, not to continue, or to interrupt a treatment. The doctor must inform them about consequences and alternatives, respect their will, and ensure appropriate assistance, including pain therapy and, under the envisaged prerequisites, continuous deep palliative sedation.
It is incorrect to turn every interruption of treatment into a case of homicide of the consenting person. If the healthcare provider limits themselves to respecting a valid patient refusal under Law no. 219 of 2017, the situation remains in the field of care decisions. The point changes if a third party performs an act aimed at directly causing death, rather than implementing the refusal or revocation of a medical treatment.
Palliative care is not a criminal shortcut
Palliative care and pain therapy serve to alleviate suffering and preserve human dignity in the final phase of life. Continuous deep palliative sedation requires the conditions provided by law and patient consent. The purpose of care and relief remains central: it is not a private procedure to cause death, nor a general exception to Article 579 c.p.
Even the patient's will must be documented in ways appropriate to their conditions. For this reason, before a delicate healthcare choice, received information, the medical record, the capacity to understand the decision, and any subsequent revocation of consent assume relevance. A decision can be modified as long as the person is able to express it.
The difference with medically assisted suicide
Assisted suicide and homicide of the consenting person are distinct offenses. In homicide of the consenting person, a third party causes death. In assisted suicide, regulated by Article 580 c.p., the third party reinforces another person's suicidal intent or facilitates its execution, while the final act remains performed by the interested person.
Constitutional Court Judgment no. 242 of 2019 identified a circumscribed area of non-punishability for facilitating the execution of a suicidal intent, not for homicide of the consenting person. The ruling requires, among other things, a person fully capable of deciding freely and consciously, suffering from an irreversible pathology causing intolerable suffering and kept alive by life-support treatments; it also requires checks by a public structure of the National Health Service and the opinion of the territorially competent ethics committee. These limits are indicated in judgment no. 242 of 2019.
There is no automatic extension of this ground of non-punishability to Article 579 c.p. The Constitutional Court, with judgment no. 132 of 2025, declared inadmissible the questions raised on homicide of the consenting person regarding the administration of the drug by a third party to a person unable to self-administer it. The decision did not introduce a general derogation for heteronomous administration: the limit between the person's own act and the action directly causative by a third party therefore remains essential. The text can be consulted in judgment no. 132 of 2025. The inadmissibility ruling rests on an insufficient inquiry into the availability of self-administration devices; it is not a general merits ruling. The Court also recognised that the National Health Service must support people admitted to the procedure by seeking and providing suitable devices, where available, and helping them use them.
What circumstances truly change the qualification of the fact
Criminal reconstruction starts from concrete facts, not from the label used by those present. Saying "they gave me permission" does not resolve whether that will truly existed, whether it was free and current, and above all, whether the third party's conduct caused death. The distinction between material assistance, execution of a therapeutic choice, and directly lethal act cannot be replaced by a private definition of the event.
The person's clinical conditions, the content of medical talks, received information, informed consent documents, advance healthcare directives, communications between those involved, and the sequence of performed acts can assume relevance. Every document must be read for what it says: an advance directive may concern future treatments, but does not automatically authorize conduct extraneous to its object.
It is equally important to distinguish an express request to refuse therapy from a generic desire to die. The first can fit into the care relationship regulated by Law no. 219 of 2017; the second, alone, does not confer upon family members, acquaintances, or healthcare operators the power to cause death. If a person is in immediate danger or expresses the intention to harm themselves, the priority is to protect them and immediately activate rescue through the single emergency number 112.
Choices not to be confused in an end-of-life situation
The first alternative is healthcare: a capable person can receive information, accept or refuse treatments, ask for their decisions to be respected, and access pain therapy measures and palliative care provided by the legal system. In this path, the relationship with the healthcare structure and the correct documentation of will are part of protecting the person, not a formal detail.
The second alternative concerns medically assisted assisted suicide, which cannot be confused with a private intervention by family members or acquaintances. The non-punishability outlined by the Constitutional Court for Article 580 c.p. operates only within specific requirements and checks; it is not a general declaration that those who suffer can ask another person to cause their death.
Finally, when there is an accusation or fear of a charge, it is not wise to rely on simplified explanations like "they consented" or "they wanted to stop suffering". It is necessary to precisely separate legitimately expressed therapeutic decisions, assistance conduct, and acts that may have caused death.

Frequently asked questions
Does written consent avoid the crime of homicide of the consenting person?
No. A written document can be evaluated to reconstruct a will, but it does not authorize another person to cause death. If consent is free and valid, it may be relevant for Article 579 c.p.; if it is absent, flawed, or given by an incapable person, provisions relating to homicide may apply.
If the person is of legal age and lucid, can I help them die?
Age of majority is not enough. Article 579 c.p. punishes causing death even with the consent of the adult and capable person. Lucidity and freedom of choice are important to evaluate the validity of consent, but they do not transform a third party's directly causative action into generally lawful conduct.
Is refusing artificial ventilation, nutrition, or hydration homicide of the consenting person?
No, not automatically. Law no. 219 of 2017 recognizes the capable person's right to refuse or revoke medical treatments, including artificial nutrition and hydration. The doctor must respect a valid and documented will; the situation changes if a third party performs an additional act aimed at causing death.
What is the difference between homicide of the consenting person and assisted suicide?
The central difference is who performs the final act. In homicide of the consenting person, the third party causes death; in assisted suicide, the third party facilitates or reinforces the intent, while the concluding act is performed by the interested person. The ground of non-punishability identified by the Court in 2019 concerns only a circumscribed area of Article 580 c.p.
Is a healthcare provider never liable if they respect the patient's will?
It depends on the conduct performed and the regulatory context. The doctor who respects a valid refusal or revocation of treatment under Law no. 219 of 2017 operates within a framework different from homicide of the consenting person. The healthcare qualification, however, does not make any conduct lawful: distinguishing respect for a therapeutic choice from the direct causation of death remains decisive.
A boundary requiring precise words
In this matter, the words used are not interchangeable. Consent, refusal of care, palliative sedation, assisted suicide, and homicide of the consenting person indicate institutions with different prerequisites and effects. When a decision concerns the end of life or when it is necessary to understand a potential criminal charge, distinguishing facts precisely is the first way not to overlap healthcare rights and criminal liability.
