Shortly after the appellate panel released its decision, attorney Coffey filed an emergency request to Supreme Court Justice Anthony M. Kennedy ( who has jurisdiction over such matters from Florida ) requesting assurance that Elian will remain in the United States until the full Supreme Court can consider a formal appeal.

Verb: serves
Output:
Yes
