A lawyer for Andrew H. Speaker, who made headlines in 2007 when he took a trans-Atlantic commercial flight while infected with a rare strain of tuberculosis, on Tuesday appeared before a federal appeals court panel in a bid to revive his lawsuit against the Centers for Disease Control and Prevention.

The case brought by Speaker, an Atlanta personal injury lawyer, is at the 11th U.S. Circuit Court of Appeals because U.S. District Judge William S. Duffey Jr. dismissed the case in November. At issue is whether the complaint in the lawsuit contained sufficiently specific allegations in light of a pair of recent U.S. Supreme Court cases that toughened standards for what must be alleged in order for a case to go forward.
