Organic Law 3/2021: Euthanasia and Art. 143 CP

Organic Law 3/2021, of March 24, on the regulation of euthanasia (BOE-A-2021-4628), introduced in Spain a right to assistance in dying in a context of serious suffering, and in doing so it amended article 143 CP. The reform fundamentally changed the criminal treatment of a historically sensitive subject: what used to be always punishable — causing another person's death at their request or cooperating in it — ceases to be so where the requirements and safeguards of the law are met. As criminal defence lawyers, we explain what the reform changed, its practical scope over art. 143 CP, and what it means today for a healthcare professional under investigation, for a relative, or for the ill person.

What the reform changed and why

Until Organic Law 3/2021, the Criminal Code punished in all cases conduct involving assisting and cooperating in another person's death, even where there was an express and free request from the ill person. The passing of the euthanasia law responded to a social demand and to a long-standing ethical and legal debate: recognising that, in situations of serious and irreversible suffering, a person with full capacity may decide to end their life and receive help to do so within a regulated framework.

That is why the reform did not simply decriminalise in a generic way. It did something more precise: it created a safeguarded procedure — with repeated requests, information, reflection periods, verification by doctors and by a guarantee and evaluation commission — and, in parallel, it amended art. 143 CP so that anyone acting within that procedure does not incur criminal liability. The logic is clear: only assistance in dying that respects the euthanasia context and its safeguards falls outside criminal law; everything else remains an offence.

Art. 143 CP and its practical scope

Article 143 CP regulates the conduct related to another person's death at their request or to cooperation in their own death. In its classic paragraphs it distinguishes, in essence, several levels of seriousness:

• Inducing the suicide of another person.
• Necessary cooperation in another's suicide.
• Cooperation that goes as far as carrying out the death, with a more intense criminal response.
• A specific provision for cases of an express, serious and unequivocal request by someone suffering a serious illness leading to death or causing permanent and hard-to-bear suffering, a scenario that already received a mitigated treatment.

Organic Law 3/2021 added to this article a new paragraph that operates as a ground for exemption from criminal liability: it is not punishable to cause or actively assist another person's death where that action takes place in accordance with the euthanasia law. The practical scope is decisive: the conduct of the healthcare professional who carries out the assistance in dying, or of someone who cooperates in it within the legal channel, ceases to fall within the offence type. Anyone wishing to place the conduct within the body of provisions can consult the Criminal Code.

The requirements of the euthanasia context

The exemption is neither automatic nor unconditional: it only operates where the euthanasia context that the law defines is met. In summary, this requires:

• The patient's consent: a free, voluntary, conscious and informed request, made in writing and repeated over time, without external pressure, by a person with the capacity to decide. The law also provides the channel of the advance directives document for those who can no longer express their will.
• An enabling clinical situation: that the person suffers a serious, chronic and disabling condition or a serious and incurable illness, on the terms the law itself defines, with physical or psychological suffering it deems intolerable.
• A safeguarded procedure: the regulated pathway of requests, information, deliberation periods, the intervention of the responsible doctor and of a consulting doctor, and prior verification by the relevant guarantee and evaluation commission.

These three elements — consent, clinical situation and procedure — are the core that separates the lawful from the punishable. Documenting them is, moreover, the backbone of any defence in this field.

Outside the requirements: the conduct remains punishable

It is essential to stress the other side of the reform. Organic Law 3/2021 did not decriminalise generally assistance in death. Where one of the requirements of the euthanasia context is missing, the exemption does not apply and the conduct becomes punishable again under art. 143 CP, as inducing or cooperating in suicide, depending on the case.

Outside the exemption — and potentially constituting an offence — therefore remain situations such as:

• Acting without valid consent from the ill person, or against a will that is not free, serious, unequivocal and sustained.
• Assistance in dying where the clinical situation the law requires is not present.
• Failure to comply with the procedure and the safeguards: omission of requests, of time periods, of verification by the participating doctors or by the guarantee commission.

Hence the boundary between the lawful provision of assistance in dying and a possible offence does not depend on intention or compassion, but on the objective compliance with the requirements and the legal channel.

What it means today for someone investigated or accused

For a healthcare professional who has participated in providing assistance in dying, the reform offers a framework of legal certainty previously lacking: acting within the legal procedure excludes criminal liability. But that certainty depends on something very concrete, the documentary traceability of the whole process.

In practice, an investigation in this area usually turns not on whether there was an intervention in the death — which may be acknowledged — but on whether the requirements and safeguards were met. That is why the clinical record, the signed requests, the medical reports, the time periods respected and the commission's verifications acquire a central evidential value.

A relative may also find themselves under investigation, for example if their intervention outside the legal channel is questioned. In such cases, distinguishing each person's role and the actual knowledge they had of the clinical situation and the ill person's will is decisive.

Lines of defence

A technical defence against a charge related to art. 143 CP in the euthanasia context is built mainly around proving compliance with the procedure and the legal safeguards. Several axes flow from this:

• Proof of consent: documenting that the request was free, voluntary, informed, written and repeated, or that there was a valid advance directives document, and that the person had the capacity to decide.
• Evidence of the clinical situation: providing the reports that support the serious, chronic and disabling condition or the serious and incurable illness, in line with the law's criteria.
• Verification of the procedure: demonstrating that the time periods, the interventions of the responsible and consulting doctors, and the verification by the guarantee and evaluation commission were respected.
• Individualisation of the conduct: where several people are involved, precisely distinguishing what each one did and with what knowledge, avoiding generic attributions of liability.

To this are added the general safeguards of criminal procedure: the presumption of innocence, the rigorous assessment of the evidence, and the correct interpretation of the exemption introduced by the reform. Each of these fronts must be assessed in light of the specific clinical documentation. You can review the context of this and other amendments on our criminal law reforms page.

What it means for the ill person and their family

For the person suffering the illness and for those around them, the reform recognises a regulated channel to request assistance in dying and gives legal certainty to those who provide it within the law. Some useful guidance from a criminal-law perspective:

• Follow the legal channel: decisions about the end of life must be channelled through the procedure the law establishes, which is precisely what excludes criminal liability.
• Document the will: leaving a written record and, where appropriate, setting out advance directives strengthens both respect for the patient's will and the position of those who intervene.
• Seek advice when in doubt: where doubts arise about compliance with the requirements or about each participant's role, an early legal analysis avoids actions that may fall outside the scope of the exemption.

A calm criminal-law analysis helps to understand where the boundary lies between the lawful provision of assistance in dying and the conduct that art. 143 CP continues to punish.
