The paper deals with a Letter of rights for persons arrested on the basis of a European arrest warrant, a novelty introduced by the Directive 2012/13/ EU on the right to information in criminal proceedings. The Directive stipulates that Member States of the EU shall ensure that persons who are arrested for the purpose of the execution of an European arrest warrant are provided promptly with appropriate Letter of rights containing information on their rights according to the law implementing the Framework Decision 2002/584/JHA on the European arrest warrant in the executing Member State. The paper is divided into three sections. First section presents fundamental knowledge on starting points of the letter of rights. Further, second section analyses its legal basis, i.e. Directive 2012/13/EU. The last third section introduces an indicative model of letter of rights.
