Section 7(4) contains the necessary prohibition. This is in line with the practice being adopted in other member states in respect of the role of seconded members in joint investigation teams. Seconded members may be present, however, when investigative measures are taken, unless otherwise decided by the team leader. Evidence obtained during the course of an investigation will remain in the possession of the Garda Síochána or, if not already in its possession, will be taken into its possession.
