A three-judge panel focused on questions of possible juror misconduct as it heard the appeals of former Alabama Gov. Don Siegelman and former HealthSouth chief executive Richard Scrushy, who were convicted two years ago on federal corruption charges. Siegelman, who served as governor from 1999 to 2003, and Scrushy were convicted on bribery and other charges stemming from $500,000 in donations arranged by Scrushy to retire undisclosed debt from Siegelman's failed 1999 lottery campaign.
