They didn’t. The judges refused to, and he was no teenager if its the case I am thinking of (the McKinnon case).
OK, thanks for the correction - I just remembered they were going to extradite him and at least a lower court OK’ed that.
But what’s really strange is that they would extradite their own citizens (examples provided in article) and refuse extradition of a foreign national. OK, each case is judged on its own merits, but no country should ever extradite their own citizens. Try them at home if you must.
