Companies doing business in Latin America face an enhanced risk of lawsuit abuse in the region under proposed changes to the countries’ court systems, according to reports from the U.S. Chamber Institute for Legal Reform released Tuesday.

In “Following Each Other’s Lead: Law Reform in Latin America” and “Class Action Evolution: Improving the Litigation Climate in Brazil,” the Institute said potential judicial reforms in Argentina, Brazil and other Latin American nations could leave businesses at a significant disadvantage as defendants, greatly tilting the courts in favor of plaintiffs.
