Having entered a reservation in respect of the European Convention on Extradition of 1957 to the effect that it will not grant extradition of persons wanted for an offence punishable by a life sentence or detention order, Portugal states that where extradition is sought for an offence punishable by a life sentence or detention order, it will grant extradition, in compliance with the relevant provisions of the Constitution of the Portuguese Republic, as interpreted by its Constitutional Court, only if it regards as sufficient the assurances given by the requesting Member State that it will encourage, in accordance with its law and practice regarding the carrying out of sentences, the application of any measures of clemency to which the person whose extradition is requested might be entitled.
Po vložitvi pridržka glede Evropske konvencije o izročitvi iz leta 1957 v tem smislu, da se ne dovoli izročitev oseb, ki se zahtevajo zaradi kaznivega dejanja, za katero je zgrožena kazen dosmrtni zapor ali priporni nalog, Portugalska izjavlja, da bo v primeru, ko se zahteva izročitev zaradi kaznivega dejanja, za katerega je zagrožena kazen dosmrtni zapor ali varnostni ukrep, v skladu z ustreznimi določbami Ustave Republike Portugalske, kot jih tolmači njeno Ustavno sodišče, izročitev dovolila le, če bo štela, da so podana zadostna zagotovila države članice, ki vlaga zahtevo, da bo v skladu s svojo zakonodajo in prakso v zvezi z izvrševanjem kazni spodbudila uporabo katerih koli ukrepov pomilostitve, do katerih bi zahtevana oseba utegnila biti upravičena.
