Latin America scholars have largely neglected the constructivist role of legal discourse as it relates to the region's national legal systems. This dimension of law includes the range of traditional legal scholarship in all its various stripes. It also extends to other forms of legal writing, including expert consultant reports, multidisciplinary studies, and transnational work.

The present Essay-while not a review of her book-explores the broader area in which she writes: namely, Latin American legal transnationalism.
