UK High Court Rules on Stuu’s Extradition

British judges have approved the extradition of Polish YouTuber Stuart K-B, better known as Stuu, to Poland to face four criminal charges, including two related to sexual contact with girls under 15 and two for encouraging minors to drink alcohol. The High Court in London, in a judgment dated 17 July 2026, dismissed arguments from the defence that he would be denied a fair trial in his home country and that the Polish judge who ordered his arrest was not independent.

Stuu, born in London in 1992, rose to fame in Poland after moving there in 2014. His main YouTube channel was once the fifth most-subscribed in the country. He returned to the UK in 2020. In September 2023, following an exposé by another YouTuber that detailed alleged contact with underage girls, Polish prosecutors launched an investigation. Just days later, on 14 October 2023—the eve of a parliamentary election—Stuu was arrested in the UK on an Interpol red notice, and a day later a Warsaw court issued a domestic arrest warrant. The speed and timing of the arrest, as well as statements by senior politicians, triggered controversy.

Stuu was released on bail in the UK shortly afterward and fought the extradition. The case moved through two British court instances. The first-instance court ruled against him in February 2025, and now the High Court has upheld that decision. Unless the ruling is further appealed, Stuu will be sent to Poland to hear the charges against him in a formal setting.

Behind the Legal Arguments in the Stuu Extradition Case

Why the Defence Argued for an Unfair Trial

Stuu’s lawyers built their case around the argument that Poland’s judicial system could not guarantee a fair trial. They pointed to the involvement of Judge Dariusz Łubowski, who issued the arrest warrant, and his earlier decision to refuse a European Arrest Warrant (EAW) for former Polish government official Marcin Romanowski. In that earlier ruling, Łubowski had described Poland’s situation as a “crypto-dictatorship” and stated that executive comments on Romanowski’s case had encroached on judicial independence. The defence also highlighted that the warrant was issued on a Sunday—Poland’s election day—and that politicians, including the prime minister, had publicly celebrated the arrest before the court even acted.

Additionally, the defence argued that Łubowski’s subsequent removal from cases involving Romanowski and a proposed EAW for former justice minister Zbigniew Ziobro, and his resignation from the international cooperation section, cast doubt on his impartiality. They had only limited access to case files, they said, and the rush to arrest Stuu suggested political interference.

The UK Court’s Assessment of Political Interference

The High Court was not persuaded. It found that the judge had 30 years of experience, had been appointed long before the judicial reforms that Poland has been criticised for, and acted as an independent judicial authority when issuing the warrant. There was no evidence that Łubowski had been subject to political pressure in Stuu’s case. The court noted that while politicians directed their statements at the public, police and prosecutors, there was no proof they had instructed or influenced the judge.

The fact the warrant was issued on a Sunday was justified by procedural deadlines. The speed of the investigation was explained by the high-profile nature of the case, the risk of flight and the accused’s awareness of the allegations. The court also observed that the defence’s central claim rested on a single prior decision by the judge—the refusal of the Romanowski EAW—which did not demonstrate any personal bias against Stuu.

No Individual Risk of a Flagrantly Unfair Trial

A critical point in the judgment was that, even if general deficiencies in Poland’s rule of law were acknowledged, the defence still had to prove that Stuu personally faced a real risk of a grossly unfair trial. The court found no such individual risk had been established. It stressed that the mere existence of systemic concerns does not automatically render every trial unfair, and the burden of proof was not met.

The ruling is significant for Poland’s legal standing abroad: a British court has taken a case-by-case approach, distinguishing between broad rule-of-law criticism and the fairness of a specific trial. Antoni Żukowski, an attorney from the BLSK law firm, told Business Insider Poland that the High Court’s decision is an important reference point in the debate over the independence of Polish judges in cross-border cooperation.
