The ECHR ruled on Thursday, 22 October 2026, that Switzerland violated Keller's right to a fair trial, a finding linked to the denied weekend exercise break.
Switzerland must pay Keller CHF5,000 ($6,095) for procedural irregularities, after the court found he had not been given sufficient opportunity to comment.
The court rejected or declared inadmissible his complaints on private life and inhuman treatment, which covered his detention at Pöschwies from August 2018 to March 2021.
A proceeding over altercations with prison staff remains before the Zurich High Court, and a case over a knockout of an opponent is also still pending after his release in November 2023.
The European Court of Human Rights (ECHR) found on Thursday, 22 October 2026, that Switzerland breached Brian Keller's right to a fair trial. The judges held that he had not been given sufficient opportunity to comment on the matter, and the court ordered Switzerland to pay him CHF5,000 ($6,095) in compensation for procedural irregularities. The violation is tied to the refusal to grant him his exercise break on weekends, which the court linked to the fair-trial complaint. Keller, a former boxer once described as Switzerland's most famous inmate, is known in media coverage under the pseudonym "Carlos". The judgment covers only part of his application.
Keller took his case to Strasbourg over his conditions of detention at Pöschwies prison in Zurich, where he was held from August 2018 to March 2021. For a period he spent 23 hours a day in an individual cell and had one hour of outdoor exercise. He also objected to being denied that exercise break on weekends and public holidays, and to medical care he considered inappropriate. The court rejected or declared inadmissible his other grievances, which concerned his right to private life and the prohibition of inhuman treatment. Because those complaints were not admitted, the court did not examine their merits.
During his years at Pöschwies, Keller often had contact only with prison staff, and he frequently clashed with them. Those disputes form part of a proceeding still pending before the Zurich High Court. Keller was released from prison in November 2023. Since his release he has come into conflict with the law several times. Among other incidents, he knocked out an opponent after the two had provoked each other on social media, and that case is also still pending.
The timeline runs from August 2018, when Keller began his detention at Pöschwies, to the judgment published on 22 October 2026. He lodged his complaints during 2021, the year before he was held at the prison until March 2021 ended. He walked free in November 2023, and the court's findings came nearly three years later.
The court's finding concerns only the weekend exercise issue and the fair-trial question, not the wider conditions of his confinement.Pollar is free and carries no ads in the text. Its members keep it going.
