The EJN and Eurojust published a joint note on the practical application of the EIO. The document aims at providing guidance to practitioners on the practical application of the EIO by looking at the issuing phase, the transmission phase, the recognition phase, and the execution phase. The note provides additional information on the scope of the Directive, its use in comparison to other co-existing legal instruments, on competent authorities, the use of a number of specific investigative measures. It also addresses the content, form, and language of the EIO. The note is based on information gathered by Eurojust and the EJN from meetings, documents, and casework. For a recent meeting report on the EIO by Eurojust, see eucrim 1/2019, p. 37 and the article by Guerra/Janssens in the same issue at pp. 46-53.
