There are more than 85 users of the Case Matrix tool and Network services around the world, most of them institutional. There is considerable diversity among them. One group of users encompasses investigation and prosecution agencies in States directly affected by core international crimes, including Argentina, Bosnia and Herzegovina, Indonesia, Iraq and Serbia. A second group consists of similar agencies in non-territorial States, such as Canada, Denmark, the Netherlands and Norway.

A further group is made up of non-governmental organizations such as Amnesty International, the Documentation Centre for Cambodia, Human Rights Watch, and the International Bar Association. A fourth group comprises internationalised criminal jurisdictions such as the ICC, the Extraordinary Chambers in the Courts of Cambodia and the Special Court for Sierra Leone. Military lawyers, defence counsel and counsel for victims are also users of the Matrix and Network services.

To date access to the Case Matrix has been granted to qualified users on the basis of request. The community of users includes institutions and individuals representing a variety of professional groups, coming from common law and civil law countries, with different working languages and public as well as civil society experience. Some individual experts and Governments have been given access because they are making specific contributions to the development and implementation of the Case Matrix. All criminal justice agencies that are working on concrete core international crimes cases should be offered access to the Case Matrix by the end of 2011.

Some Case Matrix users only need the three main legal information services of the Matrix: the 'Legal text', the 'Elements Digest' and the 'Means of Proof Digest'. Others use the evidence database function, the logic of which has been adopted in a number of decisions by the ICC. Many users draw on the training, coaching and advisory services of the Case Matrix Network, customised to their needs. Over time, the Network develops trust, familiarity and closer working relations with user institutions. At the same time, the Network is gradually expanding its working capacity in a cost-effective manner.

Localised versions of the Case Matrix can be made both in terms of law and language. Such versions have been made for Cambodia and Indonesia, and other versions are being prepared. Different models can be developed for localised versions depending on the practical needs of the user.
