Key legal question
Whether extradition had to be refused because of alleged serious mistreatment and human-rights concerns in France.
Extracted holding
No; the alleged mistreatment was not shown to be attributable to the requesting authorities, and stricter prison conditions abroad do not by themselves bar extradition.
Extracted reasoning
The court found no proof of official involvement in the alleged violence and held that the ECHR does not guarantee detention in the most lenient system.
