Effective Interviewing

Although the prohibition of torture is absolute, it frequently occurs during questioning by authorities and for the purpose of obtaining a confession and solving crimes. Around the world, false confessions and unreliable information arising from torture and ill-treatment during questioning have led to wrongful convictions, wasted resources, and miscarriages of justice. To address this, in 2016, Professor Méndez presented his last thematic report to the General Assembly as Special Rapportuer on Torture, calling for the development of a universal protocol on investigative interviewing and attendant legal safeguards. Professor Méndez advocated that non-coercive, ethically sound, evidence-based and empirically founded interviewing practices will enhance human rights compliance, optimize policing efforts, and make communities safer. After over four years of collaborative effort, we are pleased to share that the Principles on Effective Interviewing for Investigations and Information Gathering, which will be referred to as the "Mendez Principles," were launched during an online event on June 9, 2021. 

A website dedicated to the Mendez Principles can be found here.

 

Developing the Principles on Effective Interviewing for Investigations and Information Gathering

Following strategy meetings in 2017 and 2018, the Anti-Torture Initiative, Association for the Prevention of Torture (APT), and the Norwegian Centre for Human Rights (NCHR) formed an institutional partnership to coordinate the development of and advocacy around the Mendez Principles. The ATI and its partners assembled a group of renowned experts to comprise the working groups of the initiative, representing geographical diversity, gender balance, diverse perspectives, and deep expertise in the substantive thematic areas that comprise the Mendez Principles. This included a Steering Committee (15 multi-disciplinary experts tasked with overseeing the development of the principles), an Advisory Council (+80 experts who provide technical and substantive input on various drafts), a Drafting Group, and an Editorial Group. 

Drafting of the document began in 2018 and was completed in May 2021. The Mendez Principles, which are grounded in science, law and ethics, provide guidance on how to conduct rapport-based interviewing, which is more effective in obtaining accurate information and more respectful of the human rights of persons being interviewed. The Mendez Principles aim to transform the relationship between States and their citizens and are intended to change how State authorities conduct interviews and as a result improve civic trust in the State. 

Broad in their scope and flexible in their application, the Mendez Principles apply to all interviews by information-gathering officials and are suitable for uncomplicated interviews as well as interviews that are more complex. The guidance provided in the Mendez Principles is intended for policymakers, interviewing professionals, and authorities involved in the conduct of interviews, including law enforcement and intelligence-gathering agencies. The goal is for the 6 principles elaborated in the document to be incorporated into States’ domestic laws, regulations, practices, and trainings.

The Mendez Principles will assist authorities around the world to improve the effectiveness and fairness of their investigations. By moving away from a culture of accusatory, coercive and confession-driven practices, States can draw upon the principles’ best practices and help ensure that the presumption of innocence is respected, that only guilty persons are convicted, that wrongly accused persons are freed, and that justice is served for victims and society at large.
