Latin America enriches the legal landscape through its contradictions. It is a region known for its rich cultural and socio-economic diversity and its law is shaped by this diversity as legal systems have evolved to reflect the unique social, economic and political realities of each State in the region. Contrasting with this diversity is a commonality, an Iberian heritage in language and culture and above all, from a legal perspective, the common roots of the law that today's Latin American States have drawn upon. This handbook reflects this contradictory diversity focusing on criminal law, constitutional law and international law, i.e., the three areas to which Latin American law makes a particular contribution. It is of interest to all persons and institutions who want to deepen their knowledge about Latin America's legal diversity.
