[JURIST] Germany's Federal Constitutional Court [official website in German; Wikipedia backgrounder] blocked the extradition of a suspected al-Qaeda financier to Spain on Monday, ruling that the European Union arrest warrant [EU backgrounder] against him violated his rights. Mamoun Darkazanli, charged with supporting and financing al-Qaeda activites, holds both Syrian and German citizenship. The court ruled that since German law prohibits the handover of its own citizens, the warrant was invalid. Other EU states have been slow to work provisions of the EU arrest warrant [JURIST report] into their own laws, and some have even objected outright [JURIST report] to it, complaining of inequity, unfairness, or vagueness [Deutsche Welle report]. Reuters has more.
