Tate brothers will fight extradition to the UK. But the law makes it difficult to win

Any U.S. extradition of Andrew and Tristan Tate would first need a judge to find a "reasonable basis" under the U.S.–U.K. treaty, then the U.S. Secretary of State makes the final decision — with appeals the process could take years.
Extradition hearings aren’t trials and generally favor the government (it can submit broad evidence), so outright defense wins are uncommon, though charges can sometimes be narrowed.
The U.S. has transferred many suspects to the U.K. but has also blocked high‑profile requests (e.g., a 2015 art‑theft case and the 2020 Sacoolas matter), so outcomes aren’t automatic.
