For the mandatory ground for refusal of extradition based on the purpose of political persecution (disguised as a request for surrender for an ordinary offence) to apply, the person concerned must put forward concrete elements from which it can be inferred that surrender would lead to a violation of fundamental rights or, in any event, to persecution on grounds of race, religion, or political opinions. Accordingly, generic fears of being subjected to inhuman or degrading treatment—based on personal or emotional relationships with third parties—are insufficient, where such circumstances bear no connection to the criminal proceedings in respect of which the sentence to be enforced was imposed.
