The RaidForums extradition saga lurched back into the UK appeal courts on 7 May 2026, with British ministers asking the Court of Appeal for permission to challenge a ruling that wrecked their plan to send the alleged founder, Diogo Santos Coelho, to the United States ahead of Portugal. The bid, first reported by Law360 on Thursday, is the Home Office’s last realistic shot at reviving a US handover that the High Court tore up last September on procedural grounds.
Coelho, 25, a Portuguese national diagnosed with autism, was arrested by the UK’s National Crime Agency in January 2022 on a flight from Portugal at Washington’s request. He spent roughly six months in custody before a magistrate granted conditional bail in August 2022, a decision the US tried and failed to overturn at the High Court. He has been on tight bail conditions in the UK ever since while two governments fight over who gets him first. The clock is ticking, and the appeals court will now decide whether the UK can re-prioritise Washington over Lisbon.
What Happened on 7 May in the RaidForums Extradition Fight
The Home Office filed its application on Thursday seeking permission to take the RaidForums extradition row to the Court of Appeal. Ministers want to overturn the September 2025 High Court judgment from Mr Justice Linden, which quashed the previous Home Secretary’s decision to send Coelho to the United States rather than to his home country. That ruling did not free Coelho. It forced the Home Secretary to reconsider, and it gave Portugal real leverage for the first time.
Britain’s argument now is dead simple. Ministers say the Home Office was entitled to prioritise the US request, which landed first and carried the heaviest charge sheet, even though Portugal had since issued its own warrant in 2024. The High Court disagreed and found the process procedurally unfair because Coelho was never given a chance to make representations on the priority decision. The Court of Appeal will now choose whether to revisit that question.
If permission is granted, the substantive appeal could take months to land. If permission is refused, the Home Secretary has to start again from scratch, with full submissions from Coelho’s defence on autism, modern slavery status, and Portuguese family ties. Either way, the US case is no longer on a fast track.
Who Is Diogo Santos Coelho and Why the US Wants Him
Coelho, who used the online handles “Omnipotent,” “Downloading,” “Shiza” and “Kevin Maradona,” is the alleged designer and chief administrator of RaidForums, a hacker marketplace that US prosecutors describe as one of the largest stolen-data trading hubs ever built. The site was seized by a coalition led by the FBI, the US Department of Justice, and Europol in April 2022.
The US indictment charges Coelho with conspiracy, access device fraud, and aggravated identity theft. Add it up and he faces a notional maximum of about 52 years in federal prison. Portugal’s competing case carries far lower exposure and the option to serve any sentence near his family. That is the crux of the RaidForums extradition fight.
The Vulnerability Argument the High Court Bought
Coelho was 14 when RaidForums first launched. His defence team has long argued he was groomed online by older operators who used him to front the site. His autism diagnosis, formal modern slavery referral, and high suicide risk assessment all featured in the September 2025 ruling. Mr Justice Linden found that none of this had been properly weighed when the previous Home Secretary, James Cleverly, signed the order shipping him to the US.
That is a wake-up call for Whitehall. The court did not say Coelho cannot be extradited at all. It said the priority decision had to be made fairly, with proper input from the defendant, and with proper attention to vulnerability. UK courts almost never order Home Office decisions to be retaken on natural justice grounds in extradition cases. This one was an outlier, and the Court of Appeal now has to decide whether the High Court went too far.
How Competing Extradition Requests Actually Work
The mechanics here matter. When two states ask for the same person, the receiving state has to choose. Most bilateral treaties and the European Convention on Extradition 1957 set out the relevant factors: where the offence was committed, the nationality of the requested person, the date the requests were received, and the relative seriousness of the charges. The UK applies these criteria through Section 179 of the Extradition Act 2003.
| Factor | Favours US | Favours Portugal |
|---|---|---|
| Date request received | Yes (2022) | No (2024) |
| Nationality of defendant | No | Yes (Portuguese) |
| Where offending occurred | Mixed (US victims) | Mixed (server, code in Portugal) |
| Maximum sentence exposure | Yes (~52 years) | No (much lower) |
| Defendant’s consent | No | Yes (consents) |
| Vulnerability factors | Heightens risk | Reduces risk |
Read the table and the priority decision is not as obvious as Whitehall pretended. Older request and heavier charges pull one way. Nationality, consent, and vulnerability pull the other. The High Court did not pick a winner. It said Coelho’s lawyers had to be heard before the Home Office picked one.
Why This Case Hits Far Beyond RaidForums
Three reasons, and they will outlive Coelho’s case file.
First, this is the first modern UK ruling that puts modern slavery and severe autism front and centre in a Section 179 priority decision. Defence teams in every cybercrime extradition fight from now on will lift this playbook.
Second, it weakens the assumption that the US always gets first call on global cybercrime defendants who pass through London. The European Arrest Warrant framework no longer applies post-Brexit, but bilateral cooperation with EU states has not collapsed. Portugal has shown that a focused, well-evidenced request can put Washington in a queue.
Third, it raises the cost of every DOJ Office of International Affairs request that targets a vulnerable national of a friendly EU state. UK courts will now expect the Home Office to do the analysis the High Court demanded. That is real friction in the system.
What Happens Next in the RaidForums Extradition Saga
Three scenarios. None of them are quick.
If the Court of Appeal refuses permission, the case goes back to the current Home Secretary for a fresh priority decision, this time with full submissions from Coelho’s defence. That decision is itself reviewable, so even a refusal would not end the litigation.
If permission is granted and the appeal succeeds, the original priority decision is reinstated and the US extradition restarts. Coelho’s defence would almost certainly seek leave to appeal to the Supreme Court, and a separate human rights challenge under Article 3 of the European Convention on Human Rights is already in the pipeline.
If permission is granted and the appeal fails, the High Court’s framework hardens into binding precedent at the next level. That is the worst case for the Home Office and for DOJ extradition planners.
What Defendants Should Take From This Case
The RaidForums extradition fight is a textbook on how to slow down a US request from inside a UK cell. The lessons are not glamorous. They are surgical.
- Get vulnerability evidence on the file early. Autism diagnoses, suicide risk assessments, and modern slavery referrals carry weight only when they are documented before the Home Secretary signs anything.
- If a competing request from your home country is even possible, file it. Portugal’s 2024 warrant is the only reason Coelho is not already in a US courtroom.
- Demand the chance to make representations. The High Court ruled that ministers must invite submissions on competing requests. That is now a hard procedural right.
- Watch sentence exposure. A maximum of 52 years in the US versus a far shorter Portuguese sentence is the kind of differential UK courts now treat as material.
- Preserve appellate rights at every stage. Extradition cases are won and lost on whether the right point was raised at the right level.
None of this is generic advice. Each item is drawn directly from the Coelho file and the September 2025 ruling. A strategy session is the place to walk through how each one applies to a specific case.
Where the RaidForums Extradition Case Sits Inside UK Law
The Coelho saga lands in a year already heavy with cross-border activity. The extradition news desk has logged a record number of contested UK matters this spring, from the Brueckner case to the Schmitz dark web indictment. Most of those involved a single requesting state. The RaidForums extradition fight is different because it is genuinely triangular, and that is what makes it precedent-grade.
For readers who want the wider picture on UK practice, the European Convention on Extradition primer and the extradition treaties tool are the right starting points. Both explain how competing requests are filtered before they ever land on a Home Secretary’s desk. For US-side context on similar handovers, see the UK to US extradition archive. For the broader cross-border picture, the international extradition category covers comparable cases worldwide.

Final Thoughts
Governments do not play fair in extradition fights, and the RaidForums extradition saga is the cleanest proof of that in this year’s UK docket. The Home Office picked the easiest political answer in 2022, sending a vulnerable Portuguese national to the US, and a UK High Court spent three years dismantling that choice. The 7 May 2026 appeal bid is a last attempt to put the genie back in the bottle. Watch the Court of Appeal’s permission decision, and watch how Portugal’s parallel case develops in Lisbon.
