The Supreme Court Monday refused to shield Ferdinand and Imelda Marcos from having to give a federal grand jury financial records and other material. The court rejected an emergency request by the former Philippine president and first lady, who are charged with looting their country's treasury of more than $100 million. A grand jury in New York City is seeking fingerprints, palm prints, voice prints and handwriting samples from the couple, in addition to financial records. The grand jury, which previously indicted the Marcoses, is conducting further investigations. (See other court rulings on A3.)
