Cornell Law professor Michael C. Dorf discusses a lawsuit in which the government of Mexico is suing U.S. firearms manufacturers in federal court for failing to take reasonable steps to prevent their weapons from ending up in Mexico, profit from the trafficking of U.S.-made guns to Mexico, and in some respects deliberately target the illegal Mexican market. Professor Dorf argues that while the lawsuit presents strong moral and policy grounds for granting the Mexican government the relief it seeks, a 2005 federal statute, the Protection of Lawful Commerce in Arms Act (PLCAA), will likely prevent it from succeeding.

Cornell law professor Michael C. Dorf argues that the Trump administration’s new rule that would bar asylum applications from asylum-seekers who did not apply for asylum in at least one country en route to the United States is illegal, cruel, and counterproductive. Dorf explains why federal statutory law precludes such a rule and points out that while the Trump administration is not entirely responsible for the current immigration crisis, it has taken various steps to exacerbate the problem.

Cornell law professor Michael C. Dorf explains why President Trump’s threat to escalate tariffs on all Mexican goods if Mexico had not stopped the flow of Central American Migrants erroneously presumes a win-lose situation where none exists. Dorf also explains the fallacy of the criticism that immigration and trade ought to be always kept separate in negotiations.

Cornell law professor Michael C. Dorf explains why President Trump can unilaterally undermine NAFTA but cannot act to replace it without help from Congress. Dorf distinguishes treaties from “congressional-executive agreements” (NAFTA is an example of the latter), and he points out that any new agreement Trump seeks to enter with Canada and Mexico that differs in any substantial way from NAFTA can only become effective upon the passage of new legislation by Congress.

Illinois law professor Lesley Wexler analyzes the strategy of newly elected Mexican president Andrés Manuel López Obrador with respect to that country’s war on drugs and cartels—a strategy known as transitional justice. Wexler defines transitional justice and explains how the core components of transitional justice might serve as a good framework for addressing some of Mexico’s most daunting challenges.
