Section 3 deals with the establishment of joint investigation teams by the State where the Irish competent authority is satisfied that an offence has been committed, or that there are reasonable grounds for suspecting that an offence has been committed, in the State and the investigation of the offence or suspected offence has links with another member state or states; that conduct which would constitute an offence if it occurred in the State has occurred, or there are reasonable grounds for suspicion that the conduct has occurred partly in the State and partly in another member state; and that where there are reasonable grounds for believing that it would be in the public interest to establish a joint investigation team because it is anticipated or is the case that at least some part of the investigation will be conducted in the State and the investigation requires co-ordinated and concerted action with another member state or states, it may request the relevant competent authority or authorities of the other member state or states to establish a joint investigation team. Section 4 provides for the establishment of joint investigation teams on receipt of requests from other member states and contains provisions which are similar in nature to those contained in section 3.
