Damage from Lack of Informed Consent: Burden of Proof and the Right to Self-Determination

6 min read · Updated June 2026 · Editorial oversight: Avv. Federico Papa

Recent legal developments, consolidated in early 2024, highlight the complex distinction between medical malpractice and the violation of the right to self-determination. According to reports from the specialized press, compensation is not automatically granted merely for a missing signature on a form, but requires specific proof of the choices the patient would have made if properly informed. In this article, we will analyze how case law has drawn a clear line between damage to health and damage to freedom of choice. Through the reconstruction of a twin case, we will see how the burden of proof can determine the outcome of a medical civil liability lawsuit.

In brief

This article explores medical liability in the absence of a technical error, focusing on damage from omitted informed consent. It analyzes the patient's burden of proof (counterfactual test) and the criteria for the equitable assessment of damage to self-determination, distinguishing it from biological health damage.

  1. The facts

    The case stems from a surgically flawless procedure preceded by inadequate information regarding collateral risks. According to reports from outlets such as Quotidiano Sanità and Guida al Diritto, a patient complained of a deterioration in quality of life due to a specific complication which, although a known risk of the procedure, had not been communicated.

    The case reached the Supreme Court after the courts of merit had dismissed the claim for compensation, noting the absence of a technical error during the operation. At the heart of the dispute is not malpractice, but the violation of the patient's freedom to refuse a treatment involving risks that were not previously accepted.

  2. Applicable legal provisions

    The legal framework is based on Law No. 219/2017, Article 1 of which stipulates that no medical treatment may be initiated without free and informed consent. At the constitutional level, Article 13 (personal liberty) and Article 32 (protection of health) are directly engaged.

    From a civil law perspective, contractual liability is governed by Article 1218 of the Civil Code for breach of information duties. Crucially, Article 2697 of the Civil Code regulates the burden of proof: the injured party must prove not only the failure to inform, but also the concrete prejudice suffered.

  3. Case law orientations

    The Supreme Court has clarified that the right to self-determination is autonomous from the right to health. Consequently, if a physician fails to properly inform the patient, liability may arise even if the surgical procedure was technically flawless.

    However, the courts have established a strict evidentiary standard: the patient bears the burden of counterfactual proof. That is, they must demonstrate, including through presumptions, that had they been informed of the specific risks, they would have reasonably refused the intervention based on their personal circumstances and values.

  8. Lessons for professionals

    1. Tailored consent: A standard printed form is insufficient; the clinical dialogue must highlight specific risks related to the patient's professional activity.
    2. Evidentiary documentation: Medical professionals must keep clear records proving that comprehensive information was provided, in order to rebut the opposing party's presumptions.
    3. Analysis of the "No": It is essential to verify whether therapeutic alternatives existed, as their absence makes a hypothetical refusal less plausible.
    4. Damage assessment: The infringement of self-determination requires specific pleading of the subjective distress suffered as a result of being deprived of choice.

Frequently asked questions

What happens if the doctor forgets to have the consent signed but the operation goes well?

The absence of a signed consent form alone does not automatically confer a right to compensation. If the intervention was executed correctly without complications, or if the patient would have consented anyway because the treatment was essential, no compensable damage exists. Compensation is awarded only if it is proved that, given accurate information, the patient would have made a different choice.

What is the statute of limitations for a case of missing consent?

As this generally falls under the contractual liability of the healthcare facility or physician, the statute of limitations is 10 years. However, if the individual practitioner's liability is categorized as tortious, a 5-year limitation period applies. Consequently, each case must be assessed individually.

How is compensation for the breach of self-determination calculated?

Unlike biological damage, there are no fixed statutory tables. The judge assesses compensation on an equitable basis, evaluating the severity of the omission, the significance of the choice denied to the patient, and the overall impact of the complication on the individual's personal and psychological life.
