The Mexican Supreme Court Wednesday agreed to decide whether genocide charges can be brought against former President Luis Echeverria and other top officials for a 1971 massacre of protesters. Justice Jose de Jesus Gudino, writing for the court, said there was "a national interest in resolving the possible responsibility for events of the past that profoundly affected the country's political life." In July, a lower court refused to allow the charges to be filed, ruling that the statute of limitations had run. Prosecutors argued on appeal that no statutes of limitations apply under international treaties signed by Mexico. AP has more.
