Masaryk University Journal of Law and Technology Vol 11, No 1 (2017) has published an analysis co-authored by NATO CCDCOE Law Branch researcher Ms. Anna-Maria Osula on the notification requirement in transborder remote search and seizure from the perspective domestic and international law. Modern criminal investigations increasingly rely on evidence that is not in a tangible format and can no longer be assumed to be located close to the locus delicti or the perpetrator. This article focuses on the notification requirement embedded into the legal regimes regulating one of the available investigative measures employed to access data stored in digital devices – remote search and seizure. The article will first analyse whether there is an obligation under international law to notify the other state about such a transborder investigative measure. The authors compare the notification requirements for remote search and seizure in three countries’ domestic law: in Estonia, the Netherlands and the United States. Conclusions have been made on the principal challenges related to the implementation of the notification requirement under the domestic regulation. These involve balancing, on the one hand, the difficulties in identifying the location and the identity of the possible suspect and, on the other hand, the need to provide the involved individuals’ protection as guaranteed by the principles of fair trial and effective remedy.
