Section 3 deals with the amendment of the 1997 Act. The section is in two parts and amends section 4 of the 1997 Act by inserting two additional sections, 4A and 4B. New section 4A concerns directions and orders of the High Court. Thus, subsection 4A(1) provides for the tribunal, or the chairperson if the tribunal has more than one member, whenever they consider it appropriate to do so, to apply to the High Court for directions relating to the performance of the functions of the tribunal or the chairperson, under the Tribunals of Inquiry (Evidence) Acts 1921 to 2003, including their functions relating to costs.
