In countries where state institutions have limited reach, customary and informal justice is often the most common way in which people resolve disputes and seek justice. Given its prominence, it is considered to be an important element of a people-centered approach to building peaceful, just, and inclusive societies. An understanding of the relationship between customary justice and transitional justice, however, remains underdeveloped. A new ICTJ report provides valuable empirical, qualitative research on the topic, in the context of South Sudan.
