Though the preliminary injunction barring the deportations issued by Judge James Lawrence King of the United States District Court for southern Florida applies only in Florida, Georgia and Alabama, similar cases are pending elsewhere, Ira Kurzban said. Mr. Kurzban is a member of a group of Miami lawyers who brought the suit against Attorney General Janet Reno, the Justice Department, the immigration service and the Board of Immigration Appeals. Judge King set a trial date for next January.
