Spain Rejects US ‘Interference’ Over Euthanasia Case Amid Disinformation Concerns

Madrid / 4 April 2026

The Spanish government has issued a strong rebuke to the United States following comments by a senior American official calling for an investigation into a high-profile euthanasia case that has sparked national and international debate.

Spain’s Health Minister, Mónica García, accused Washington of “interference” and warned that Spain “will not allow disinformation” to shape the narrative around the case.

Landmark Case Draws International Attention

The controversy centres on Noelia Castillo, a 25-year-old paraplegic woman who underwent assisted dying last week under Spain’s euthanasia law.

Spain legalised euthanasia in 2021, becoming one of a limited number of countries worldwide to permit the practice under strict medical, legal and ethical safeguards.

Castillo first applied for euthanasia in 2024 after becoming paralysed following a suicide attempt in 2022. Her request triggered a prolonged legal battle after her father challenged her eligibility, arguing she did not meet the legal criteria

.

The dispute became Spain’s first major euthanasia case to reach European courts, with the European Court of Human Rights ultimately rejecting the father’s appeal.

US Criticism and Spanish Response

The row escalated after Riley Barnes, a US Assistant Secretary of State for Human Rights, said it was “imperative” the case be investigated, claiming Castillo had been “failed in life”.

The comments were echoed by the US embassy in Madrid, prompting a sharp response from García, who defended Spain’s legal framework and healthcare system.

She stated that Spain is a “sovereign country” with:

• Robust legislation governing euthanasia
• Independent clinical review committees
• Judicial oversight backed by European courts

García also criticised US President Donald Trump, accusing his administration of fuelling an “international extremist agenda” through interventions in foreign policy debates.

Disinformation Concerns

Spanish media, including RTVE, have reported a surge in misinformation online surrounding the case.

False claims circulating on social media have included:

• Allegations Castillo did not meet legal criteria
• Claims the Spanish state “abandoned” her
• Conspiracy theories linking euthanasia to organ donation
• Authorities say these narratives risk undermining public understanding of the law and the safeguards in place.

Wider Diplomatic Context

The dispute comes amid growing tensions between Spain and the United States, particularly since Trump’s return to power. Previous disagreements have centred on defence spending, foreign policy and Middle East conflicts.

Analysts say the euthanasia row reflects a broader clash over values, sovereignty and human rights frameworks, with Spain positioning itself as a defender of its legal autonomy.
