Finland will grant extradition of its nationals only under the following conditions: at the discretion of the Ministry of Justice, a Finnish national may be extradited to a Member State of the European Union to stand trial for a crime the most severe punishment for which, under Finnish law, is at least four years imprisonment if committed under similar circumstances in Finland; a condition of extradition is that, once the judgement has become final, the requesting Member State undertake immediately to return an extradited Finnish national to Finland for possible imprisonment if he consents to serve his sentence in Finland; no Finnish vessel on the high seas or in a Finnish aircraft; no Finnish national may be prosecuted or punished for a crime other than that referred to in the application for extradition, without the authorisation of the Ministry of Justice; no Finnish national may be re-extradited to another State.

Finland will continue to apply Article 15 of the European Convention on Extradition except where Article 13 of the Convention on simplified extradition procedure between the Member States of the European Union provides otherwise or where the person whose extradition is requested has consented to re-extradition.

The central authority in Finland pursuant to Article 13(1) is the Ministry of Justice.

Supplementary information as referred to in Article 13 of the European Convention on extradition may be communicated directly between the competent authorities in the manner referred to in Article 14. In Finland, the Ministry of Justice, the Central Criminal Police and the Supreme Court are entitled under Article 14 of the Convention to request, communicate and receive supplementary information.

The Convention may apply, before it enters into force internationally, in relations with those Member States which have made a similar declaration.
