Why this guide? The Committee was created with the main objective of promoting national implementation of the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment (UNCAT) in order to ensure increased protection for individuals and groups against torture and ill-treatment at the national level. To achieve this objective, it is essential that the intended beneficiaries, individuals on the ground, have effective access to the Committee to inform it about the situation in their country and advise on what concrete initiatives should be taken to improve that situation. However, the Committee meets in Geneva far away from many of the countries it reviews and even further removed from the individuals it is tasked with protecting. Furthermore, its working methods and practices have developed over the years into a fairly complicated process, which can be difficult to understand and engage with for persons who do not have a regular interaction. The objective of this practical guide is to explain, in a simple and concise format, how the Committee operates and how non-governmental organisations (NGOs) can engage with its State review process, which is the main process by which the Committee monitors compliance with the 6 Convention. The Committee also implements other mandates, such as deciding on individual complaints and drafting General Comments, but these will not be covered by this guide. The guide contains background information on the working methodologies of the Committee as well as practical guidance on how to best influence the process at the different stages of the State review. It starts by explaining the State reporting cycle and providing an outline of the different stakeholders. This is followed by an overview of how NGOs can best ensure that their priority issues are adequately considered at each stage of the process. Finally, the guide provides some practical guidance and strategic reflections for NGO engagement in the State review on issues such as drafting alternative reports, working in coalitions and how the process can be linked with other international human rights monitoring mechanisms. The guide focuses on engagement with the Committee against Torture, but many of the observations made herein are generally applicable to other treaty bodies. It is important to note that working methods and procedures change regularly, so it is always a good idea to check up on these before starting to engage in a State review.
