14 The ICC needs to rely substantially on the willingness of States and of international organisations to provide support and to assist it in its work.  This is especially true with respect to information and material of importance and relevance to the investigation of crimes and the prosecution of cases, and the arrest and surrender of persons alleged to have committed crimes under the ICC Statute.    Unlike the national courts, the ICC does not have at its disposal the powers and apparatus of the State legal and law enforcement system to enforce its orders and decisions.  The assistance of States parties, as well as of other States and international organisations, will therefore be of the utmost importance to the proper functioning of the ICC.    The regime of international cooperation and judicial assistance under the ICC Statute was carefully worked out.  It is one of the most important and complex parts of the Statute in its legal structure and implications, and for the interaction between the Court and States.    There is a general requirement for the States Parties, in accordance with the Statute, to cooperate fully with the Court in its investigation and prosecution of crimes within the jurisdiction of the Court.  This provision is fundamental and would need to be given full and practical effect.  Equivocation will seriously compromise the ability of the Court to achieve what it is supposed to achieve.  It is therefore vital that the Court be accorded the most effective cooperation and assistance possible.    One concrete measure of support now being widely advocated, by major Governments as by the non governmental community, is the enactment of clear and strong implementing legislation among member States.  Implementing legislation is required to set the domestic legal and procedural framework for carrying out the State’s cooperation obligations and to deal with important practical issues, including: the definition and adoption of ICC crimes into domestic law; arrest and surrender of persons; and assistance and cooperation in the investigation of offences.  A number of key States in Europe and in the Commonwealth of Nations, including Australia¹⁹ and New Zealand²⁰ and have enacted such legislation.  However, many more of the States Parties, including the small island States of the Pacific, would need to undertake this task.  The task is not an easy one, judging by the models that now exist.  The legislation in both Australia and New Zealand appear quite comprehensive and cover a range of matters that enable and facilitate assistance and cooperation with the ICC, as well as substantive criminal law and constitutional law issues.  With the necessary adaptations they could be models for others to consider.     Concluding thoughts     Of necessity this is a selective and generalised survey of the potential for law reform and related activities in the Pacific area.  But it is one that offers the basis for some general thoughts.                                                 19 International Criminal Court Act 2002 (ICC Act) and International Criminal Court (Consequential Amendments) Act 2002; see also Gillian Triggs, Implementation of the Rome Statute for the International Criminal Court: a quiet revolution in Australian law, 2003, a paper at the Twilight Seminar, Institute for Comparative and International Law, University of Melbourne.    20 International Crimes and International Criminal Court Act 2000
