Section 3 provides for the secondment of members of the PSNI to the Garda Síochána with full Garda powers for a period not exceeding three years. Secondees will continue to be paid by the PSNI but will be under the direction and control of the Garda Commissioner and have the powers, rights, duties and obligations of a member of the Garda Síochána of the rank to which they are appointed. A secondment under this section may be terminated by the Commissioner or the Government where it made the appointment. The ranks in the Garda Síochána to which members may be appointed under this section and the number to be appointed may be prescribed by regulation under the Bill. The section also makes certain technical amendments to the Garda Síochána Acts to reflect the position of secondees.
