The World Court ruled two days ago, acting on a request by the Mexican government, that five Mexicans nationals sentenced to be executed in Texas have not been given proper contact with consular authorities, which according to the court, violates treaty agreements.  Mexican national, Jose Ernesto Medellin Rojas, is the first scheduled to be executed on August 5.  The American member of the tribunal dissented on all points of the court's decision.  The issue involves a 2004 SCOTUS decision regarding the application of the Vienna Convention which is currently being considered in Congress (H.R. 6481).
