In response to this decision, the Luxembourg Public Prosecutor's office addressed a letter to the Spanish Ministry of Justice on Thursday, arguing that Kiesch should serve his residual sentence in Spain.
The Grand Duchy initially requested Kiesch be surrendered to Luxembourgish authorities following his arrest - a request which was denied by the decision taken by the Madrid Central Investigation Court on 21 August.
The judgment gave Kiesch provisional release and opposed the European arrest warrant, on the basis that Kiesch had established a new life in Spain and put down roots with a family.
Luxembourg responded to this refusal, citing the framework decision 2008/909 / JHA on the principle of mutual recognition in judgments in criminal matters in the European Union, and requesting that Kiesch's residual sentence, namely 3,275 days, be executed in Spain.
39-year-old Kiesch was sentenced for murder in 2000, and had been on the run since 2004.
