All mandatory and optional grounds for non-execution provided under articles 3 and 4 FD apply. Luxembourg authorities may also refuser to surrender a minor over 16 years of age at the time where he perpetrated the offence.
In order for the issuing State to prosecute the person subject to the EAW for an offence other than that for which he was surrendered, a request shall be addressed to the Luxembourg executing authority, unless the person renounce entitlement to the speciality rule.
Consent by Luxembourg executing authorities to subsequent surrender or extradition by the issuing State is also required under the conditions provided under article 28 FD.
In order for the issuing State to prosecute the person subject to the EAW for an offence committed before surrender other than that for which he was surrendered, a request for consent must be addressed to the Luxembourg executing authority. The request for consent must be submitted by the same procedure and must contain the same information as a normal EAW. The Luxembourg executing authority gives his consent no later than 30 days after receipt of the request when the offence for which the consent is requested is itself subject to surrender, unless a mandatory or optional ground for non-execution applies.
Such procedure does not apply in the cases listed in article 27(3) of the Framework Decision, essentially (i) when the person renounced, before or after his/her surrender, the speciality rule, (ii) when the person does not incur a penalty or measure involving deprivation of liberty in relation to the new offence, (iii) when the person having had an opportunity to leave the territory of the issuing State has not done so within 45 days of his/her final discharge, or has returned to that territory after leaving it.
