COURT RULING TO MEAN THAT IT MUST GO TO CONGRESS TO AUTHORIZE A SYSTEM FOR TRYING THE PRISONERS. CONGRESS PLANNED TO HOLD HEARINGS THIS WEEK. SENATE MAJORITY LEADER BILL FRIST SAID HE WAS CONSULTING WITH THE WHITE HOUSE AND PLANNED TO REACH OUT TO DEMOCRATS TO CRAFT LEGISLATION THAT LIKELY WILL BE ON THE FLOOR IN SEPTEMBER. "THIS DOES GIVE US AN OPPORTUNITY TO UPDATE OUR LAWS TO RESPOND TO NEW REALITIES OF A POST 9/11 WORLD," THE TENNESSEE REPUBLICAN TOLD REPORTERS. FRIST SAID HE EXPECTED CONGRESS WOULD ADDRESS GENEVA CONVENTION ISSUES ON PRISONERS' RIGHTS AS IT WORKED ON LEGISLATION, "AND I THINK THAT IS GOING TO TAKE A LOT OF DEBATE." SNOW SAID THE PRISONERS WERE IN "A HOLDING PATTERN TO THE EXTENT THAT THOSE WHO ARE NOT BEING REPATRIATED ARE GOING TO BE STAYING THERE." THE WHITE HOUSE ARGUES THAT THE TERRORISM SUSPECTS HELD AT GUANTANAMO BAY ARE DIFFERENT FROM PRISONERS TAKEN IN A WAR BETWEEN ARMIES OF TWO COUNTRIES AND THUS NEED TO BE HANDLED DIFFERENTLY. "HOW DO YOU BRING THOSE PROPERLY TO JUSTICE?" SNOW ASKED. "IN SOME CASES, IT MEANS REPATRIATING AND IN SOME CASES IT'S GOING TO MEAN FINDING A PROPER WAY, ACCEPTABLE TO THE SUPREME COURT, TO CONDUCT TRIALS. "I THINK THERE'S A LOT OF HEAD-SCRATCHING GOING ON," HE SAID. "AND PEOPLE REALLY ARE TRYING TO FIGURE OUT WHAT EXACTLY DOES THE SUPREME COURT OPINION IMPLY ABOUT THE WAY IN WHICH WE CAN PROCEED FORWARD."
