The European arrest warrant : a procedure that takes legal security into consideration?

The European union started as an area of economic cooperation, but has developed into an area of cooperation in many legal fields. There are these days even cooperation when it comes to dealing with criminals. There is a new procedure called the European arrest warrant which goal is to make the extradition of criminals between the different member states in the European union more efficient. Sometimes when a state receives a European arrest warrant they have to extradite the person in question without doing any investigation of their own. The procedure is based on the principle of mutual recognition. This principle means that the member states should recognise the legal decisions of the other member states, as they were their own. The aim of the thesis is to see if this procedure is acceptable concerning the legal security. Will the procedure with the European arrest warrant effect the legal security for the suspects, or the rest of the citizens
