Article 156 bis Spanish Criminal Code: Organ Trafficking, Offences and Penalties (2026)

Article 156 bis of the Spanish Criminal Code (CP) criminalises trafficking in human organs, one of the most heavily punished offences against the person in Spanish law. Introduced by Organic Law 5/2010, the provision does not stop at the surgeon or the broker: it covers the entire chain of the illegal organ trade — unlawful procurement, advertising, transport and storage, recruitment of donors and recipients, bribery of medical staff — and reaches the recipient who consents to the transplant knowing the organ's illicit origin. As criminal defence lawyers specialising in organ trafficking cases, we explain exactly what Article 156 bis CP punishes, with what penalties, and where the lines of defence lie.

What Article 156 bis CP Punishes

Paragraph 1 punishes anyone who "in any way promotes, favours, facilitates, advertises or carries out trafficking in human organs". The wording is deliberately broad: there is no need to perform the extraction or receive the organ. Financing the operation, putting buyer and seller in contact, or advertising an organ for sale online is enough to commit the offence. The penalty depends on the source of the organ:

• Organ from a living person: 6 to 12 years' imprisonment.
• Organ from a deceased person: 3 to 6 years' imprisonment.

The severity reflects the interests protected: the health and physical integrity of the individual, and public confidence in Spain's legal donation and transplant system, which is built on altruism and non-payment under Law 30/1979 on the Extraction and Transplantation of Organs and Royal Decree 1723/2012. Spain is also a party to the Council of Europe Convention against Trafficking in Human Organs (Santiago de Compostela, 2015).

What Counts as "Organ Trafficking"

The article itself defines three blocks of conduct for criminal purposes:

1. Unlawful extraction or procurement of another person's organs. Procurement is unlawful in three scenarios: where the living donor's free, informed and express consent is missing or does not meet the legal requirements; where the legally required authorisation is missing in the case of a deceased donor; or where the donor or a third party requests or receives a reward or payment of any kind — or accepts the offer or promise of one — in exchange for the extraction. Reimbursement of expenses or loss of income arising from the donation is not treated as a reward.
2. The logistics of the illicit organ: the preparation, preservation, storage, transport, transfer, receipt, import or export of unlawfully extracted organs.
3. The use of the organ: using unlawfully extracted organs for transplantation or for any other purpose.

The practical consequence is that every link in the chain is criminally liable: whoever extracts, whoever stores and transports, whoever imports and whoever implants. Each contribution is assessed separately, which is why these investigations typically involve many suspects.

Recruiting Donors and Bribing Medical Staff

Paragraph 2 adds two satellite offences, punished in the same way, aimed at the market surrounding the organ:

• Paid recruitment: requesting or receiving, directly or through an intermediary, a reward or payment of any kind — or accepting the offer or promise of one — for proposing or recruiting a donor or a recipient of organs.
• Bribing medical staff: offering or giving a reward or payment to medical personnel, public officials or private individuals acting in the course of their profession or position in public or private clinics, establishments or practices, so that the unlawful extraction or the implantation of unlawfully extracted organs is carried out or facilitated.

The law therefore targets both the broker who charges for recruiting donors and anyone who corrupts the doctor or the manager of the centre to make the operation happen.

The Recipient Who Consents Knowing the Illicit Origin

Paragraph 3 expressly settles the most delicate question in this area: the liability of the patient who receives the organ. A recipient who consents to the transplant knowing the organ's illicit origin faces the same penalties as the traffickers under paragraph 1, although the court may reduce them by one or two degrees in view of the circumstances of the offence and of the offender.

That discretionary reduction acknowledges the singular position of someone driven by serious illness. In practice, the recipient's defence is fought on two fronts: the proof of knowledge — the prosecution must show the recipient actually knew the organ came from an unlawful procurement; suspicion is not enough — and sentencing, where the patient's medical condition and personal circumstances can support the maximum reduction.

Aggravating Factors: Minors, Medical Professionals and Criminal Organisations

The article scales the penalties across three successive levels:

• Serious danger or vulnerable victim (para. 4): the penalty rises to the next degree where the victim's life or physical or mental integrity was placed in serious danger, or where the victim is a minor or especially vulnerable by reason of age, disability, illness or situation. Where both circumstances concur, the penalty is imposed in its upper half.
• Medical professionals and public officials (para. 5): a medical professional, public official or private individual who commits these acts in the course of their profession or position in a public or private centre receives the penalty one degree higher plus special disqualification from public employment or office, from their profession or trade, from practising any healthcare profession and from providing services in clinics or practices for the duration of the sentence. "Medical professional" expressly includes doctors, nursing staff and anyone carrying out a healthcare or social-healthcare activity.
• Criminal organisation or group (para. 6): belonging to a criminal organisation or group dedicated to these activities raises the penalty to the next degree, with special disqualification from any profession, trade, industry or commerce. Leaders, administrators or managers of the organisation receive the penalty in its upper half, which may be raised to the next degree.

The combination of aggravating factors is expressly regulated: where the involvement of a professional or a criminal organisation coincides with the circumstances of paragraph 4, the penalties are imposed in their upper half or raised a further degree, depending on the case.

Corporate Criminal Liability

Paragraph 7 provides for the liability of legal entities — a private clinic, a medical-travel intermediary, a shell company — where the offence is attributable to them under article 31 bis CP. The penalty is a fine of three to five times the profit obtained, and the court may add, under the rules of article 66 bis, the penalties listed in letters b) to g) of article 33.7 CP. For companies in the healthcare and biotech sectors, an effective compliance programme is decisive: we analyse it in our guide to the corporate criminal liability exemption through compliance.

Preparatory Acts, Human Trafficking and Foreign Convictions

The article closes with three rules that considerably widen its reach:

• Preparatory acts (para. 8): provocation, conspiracy and solicitation to commit these offences are punished with the penalty one or two degrees below. Seriously negotiating the purchase of an organ can be punishable even if the transplant never takes place.
• Overlap with human trafficking (para. 9): the penalties of article 156 bis apply without prejudice to those for the offence of human trafficking under article 177 bis CP. Where the victim was recruited, transported or harboured through violence, intimidation, deception or abuse of a situation of vulnerability for the purpose of removing their organs — one of the statutory purposes of trafficking in persons — both offences can be punished cumulatively.
• Foreign convictions (para. 10): convictions by foreign courts for offences of the same nature produce the effects of recidivism in Spain, unless the record has been or should have been expunged under Spanish law.

Defence Strategies

1. Knowledge of the illicit origin: intent must cover the unlawfulness of the procurement. For recipients, their relatives or auxiliary staff, proof that they knew where the organ came from is the critical point of the prosecution case.
2. Lawfulness of the procurement: if the living donor gave free, informed and express consent meeting the legal requirements, or the required authorisation existed for a deceased donor, there is no trafficking. Compensating expenses and loss of income is lawful and does not turn a donation into a sale.
3. Delimiting participation: promoting, favouring and facilitating are broad terms, but they require a real and relevant contribution to the trafficking chain; occasional contact or mere proximity to the recipient is not enough.
4. Challenging the aggravating factors: disputing the existence of a genuine criminal organisation as opposed to occasional co-offending, the defendant's status as a medical professional, or the victim's vulnerability can prevent the penalty from rising a degree.
5. The paragraph 3 reduction: for the recipient, seeking a reduction of one or two degrees based on illness, clinical situation and the circumstances of the offence.
6. Compliance: for legal entities, proving an adequate organisation and management model under article 31 bis CP can exclude or mitigate liability.
