Hearsay is information, too. Just goes to admissibility and, perhaps, weight.
“Paper Points to Pemex Bribe,” The Wall Street Journal, May 5, 2017 A7. Apparently, an Odebrecht employee testified that he was asked to bribe the person then the head of Pemex (Mexico’s state-owned oil company). Not clear who asked him. Odebrecht ( a large Brazilian contruction company) has admitted it paid a bunch of bribes in a bunch of countries, including Mexico. This according to a document filed in Brazil.
So, a document filed in court in one country alleges bribes to an official in another country. What’s the Mexican government to do? What’s the duty, and to whom?
