The concept of a liberal democratic society requires that the state power is governed by the principle of rule of law and respects, protects, and fulfills the fundamental human rights and basic freedoms of every human being. A democratic society further establishes active oversight mechanisms, ensuring that its foundations are effectively protected. The National Preventive Mechanism, a unique oversight body that reveals and addresses torture and ill-treatment, acts which attack the very nature of democratic values, is indisputably a key component of a well-functioning democracy. However, only the understanding of how the NPM truly works and what its philosophy is will create a genuinely effective guardian of human rights and democratic values.
