The levels of institutionalization and cooperation within BRICS are increasing each year. Although many studies attempt to explain the BRICS phenomenon, especially from economic and political perspectives, there is a lack of research focused on its legal international dimension.

This book brings together the reflections of several researchers on BRICS international legal aspects.
